This is a list of changes to Slate with each new release. Until 1.0 is released, breaking changes will be added as minor version bumps, and smaller, patch-level changes won't be noted since the library is moving quickly while in beta.
⚠️ Until is solved, each package will maintain its own individual changelog, which you can find here:
0.61 — March 29, 2021New CustomTypes for Editor, Element, Text and other implementation specific objects. Improved typing with TypeScript lets you add CustomTypes for the Slate Editor. This change requires you to set up your types at the start. It's a new concept so please read the new TypeScript documentation here:
0.60 — November 24, 2020Introduced new customizable TypeScript typings. You can override the built-in types to extend them for your own editor's domain model. However the changes to make this possible likely resulted in some changes to the existing type contracts.
The useEditor hook was renamed to useSlateStatic. This was done to better differentiate between the useSlate hook and to make it clear that the static version will not re-render when changes occur.
0.59 — September 24, 2020There were no breaking changes or new additions in this release.
0.58 — May 5th, 2020User properties on Elements and Texts now have an unknown type instead of any. Previously, the arbitrary user defined keys on the Text and Element interface had a type of any which effectively removed any potential type checking on those properties. Now these have a type of unknown so that type checking can be done by consumers of the API when they are applying their own custom properties to the Texts and Elements.
0.57 — December 18, 2019Overridable commands now live directly on the editor object. Previously the Command concept was implemented as an interface that was passed into the editor.exec function, allowing the "core" commands to be overridden in one place. But this introduced a lot of Redux-like indirection when implementing custom commands that wasn't necessary because they are never overridden. Instead, now the core actions that can be overridden are implemented as individual functions on the editor (eg. editor.insertText) and they can be overridden just like any other function (eg. isVoid).
Previously to override a command you'd do:
Now, you'd override the specific function directly:
You shouldn't ever need to call these functions directly! They are there for plugins to tap into, but there are higher level helpers for you to call whenever you actually need to invoke them. Read on…
Transforms now live in a separate namespace of helpers. Previously the document and selection transformation helpers were available directly on the Editor interface as Editor.*. But these helpers are fairly low level, and not something that you'd use in your own codebase all over the place, usually only inside specific custom helpers of your own. To make room for custom userland commands, these helpers have been moved to a new Transforms namespace.
Previously you'd write:
Now you'd write:
The Command interfaces were removed. As part of those changes, the existing Command, CoreCommand, HistoryCommand, and ReactCommand interfaces were all removed. You no longer need to define these "command objects", because you can just call the functions directly. Plugins can still define their own overridable commands by extending the Editor interface with new functions. The slate-react plugin does this with insertData and the slate-history plugin does this with undo and redo.
User action helpers now live directly on the Editor.* interface. These are taking the place of the existing Transforms.* helpers that were moved. These helpers are equivalent to user actions, and they always operate on the existing selection. There are some defined by core, but you are likely to define your own custom helpers that are specific to your domain as well.
For example, here are some of the built-in actions:
Every one of the old "core commands" has an equivalent Editor.* helper exposed now. However, you can easily define your own custom helpers and place them in a namespace as well:
Whatever makes sense for your specific use case!
0.56 — December 17, 2019The format_text command is split into add_mark and remove_mark. Although the goal is to keep the number of commands in core to a minimum, having this as a combined command made it very hard to write logic that wanted to guarantee to only ever add or remove a mark from a text node. Now you can be guaranteed that the add_mark command will only ever add custom properties to text nodes, and the remove_mark command will only ever remove them.
Previously you would write:
Now you would write:
🤖 Note that the "mark" term does not mean what it meant in
0.47and earlier. It simply means formatting that is applied at the text level—bold, italic, etc. We need a term for it because it's such a common pattern in richtext editors, and "mark" is often the term that is used. For example the<mark>tag in HTML.
The Node.text helper was renamed to Node.string. This was simply to reduce the confusion between "the text string" and "text nodes". The helper still just returns the concatenated string content of a node.
0.55 — December 15, 2019The match option must now be a function. Previously there were a few shorthands, like passing in a plain object. This behavior was removed because it made it harder to reason about exactly what was being matched, it made debugging harder, and it made it hard to type well. Now the match option must be a function that receives the Node object to match. If you're using TypeScript, and the function you pass in is a type guard, that will be taken into account in the return value!
Previously you might write:
Now you'd write:
The mode option now defaults to 'lowest'. Previously the default varied depending on where in the codebase it was used. Now it defaults to 'lowest' everywhere, and you can always pass in 'highest' to change the behavior. The one exception is the Editor.nodes helper which defaults to 'all' since that's the expected behavior most of the time.
The Editor.match helper was renamed to Editor.above. This was just to make it clear how it searched in the tree—it looks through all of the nodes directly above a location in the document.
The Editor.above/previous/next helpers now take all options in a dictionary. Previously their APIs did not exactly match the Editor.nodes helper which they are shorthand for, but now this is no longer the case. The at, match and mode options are all passed in the options argument.
Previously you would use:
Now you'd use:
The Editor.elements and Editor.texts helpers were removed. These were simple convenience helpers that were rarely used. You can now achieve the same thing by using the Editor.nodes helper directly along with the match option. For example:
0.54 — December 12, 2019The <Slate> onChange handler no longer receives the selection argument. Previously it received (value, selection), now it receives simply (value). Instead, you can access any property of the editor directly (including the value as editor.children). The value/onChange convention is provided purely for form-related use cases that expect it. This is along with the change to how extra props are "controlled". By default they are uncontrolled, but you can pass in any of the other top-level editor properties to take control of them.
The Command and CoreCommand interfaces have been split apart. Previously you could access Command.isCoreCommand, however now this helper lives directly on the core command interface as CoreCommand.isCoreCommand. This makes it more symmetrical with userland commands.
Command checkers have been simplified. Previously Slate exposed command-checking helpers like Command.isInsertTextCommand. However these were verbose and not useful most of the time. Instead, you can now check for CoreCommand.isCoreCommand and then use the command.type property to narrow further. This keeps core more symmetrical with how userland will implement custom commands.
The <Slate> component is now pseudo-controlled. It requires a value= prop to be passed in which is controlled. However, the selection, marks, history, or any other props are not required to be controlled. They default to being uncontrolled. If your use case requires controlling these extra props you can pass them in and they will start being controlled again. This change was made to make using Slate easier, while still allowing for more complex state to be controlled by core or plugins going forward—state that users don't need to concern themselves with most of time.
The Editor now has a marks property. This property represents text-level formatting that will be applied to the next character that is inserted. This is a common richtext editor behavior, where pressing a Bold button with a collapsed selection turns on "bold" formatting mode, and then typing a character becomes bold. This state isn't stored in the document, and is instead stored as an extra property on the editor itself.
0.53 — December 10, 2019The slate-schema package has been removed! This decision was made because with the new helpers on the Editor.* interface, and with the changes to normalizeNode in the latest version of Slate, adding constraints using normalizeNode actually leads to more maintainable code than using slate-schema. Previously it was required to keep things from getting too unreadable, but that always came at a large cost of indirection and learning additional APIs. Everything you could do with slate-schema you can do with normalizeNode, and more.
Node matching functions now receive just a Node. Previously they received a NodeEntry tuple, which consisted of [node, path]. However now they receive only a node argument, which makes it easier to write one-off node-checking helpers and pass them in directly as arguments. If you need to ensure a path, lookup the node first.
A few unnecessary helpers were removed. There were a handful of leftovers helpers that were not used anywhere in Slate's core logic, and were very unlikely to be used in userland, so they've been removed to reduce bundle size. You are always free to re-implement them if you truly need them. The list of helpers removed is:
Editor.ancestor
Node.closest
Node.furthest
Range.exists
Range.isRangeList
Range.isRangeMap
0.52 — December 5, 2019The slate-schema package now exports a factory. Previously you imported the withSchema function directly from the package, and passed in your schema rules when you called it. However, now you import the defineSchema factory instead which takes your schema rules and returns a custom withSchema plugin function. This way you can still use helpers like compose with the plugin, while pre-defining your custom rules.
The properties validation in the schema is now exhaustive. Previously a properties validation would check any properties you defined, and leave any unknown ones as is. This made it hard to be certain about which properties would end up on a node. Now any non-defined properties are considered invalid. And using an empty {} validation would ensure that there are no custom properties at all.
The leaves schema validation ensures text-level formatting. You can use it from any higher up element node in the tree, to guarantee that it only contains certain types of text-level formatting on its inner text nodes. For example you could use it to ensure that a code block doesn't allow any of its text to be bolded or italicized.
0.51 — December 5, 2019The Mark interface has been removed! Previously text-level formatting was stored in an array of unique marks. Now that same formatting is stored directly on the Text nodes themselves. For example instead of:
You now have:
And the marks are added and removed from the text nodes using the same Editor.setNodes transform that you use for toggling formatting on block and inline nodes. This greatly simplifies things and makes Slate's core even smaller.
The <Slate> component is now a "controlled" component. This makes things a bit more React-ish, and makes it easier to update the editor's value when new data is received after the initial render. To arrive at the previous "uncontrolled" behavior you'll need to implement it in userland using React's built-in hooks.
Whereas previously you would do:
Now you must manage the value and selection yourself, like:
0.50 — November 27, 2019⚠ Warning: Changes past this point refer to the older Slate architecture, based on Immutable.js and without TypeScript. Many things are different in the older architecture and may not apply to the newer one.
0.47 — May 8, 2019Introducing the Annotation model. This is very similar to what used to be stored in value.decorations, except they also contain a unique "key" to be identified by. They can be used for things like comments, suggestions, collaborative cursors, etc.
There are three new *_annotation operations. The set of operations now includes add_annotation, remove_annotation and set_annotation. They are similar to the existing *_mark operations.
Introducing "iterable" model methods. This introduces several iteratable-producing methods on the Element interface, which Document, Block and Inline all implement. There are iterables for traversing the entire tree:
You can use them just like the native JavaScript iterables. For example, you can loop through the text nodes after a specific node:
Or you can traverse all of the "leaf" blocks:
And because these iterations use native for/of loops, you can easily break or return out of the loops directly—a much nicer DX than remembering to return false.
The value.decorations property is now value.annotations. Following with the split of decorations into annotations, this property was also renamed. They must now contain unique key properties, as they are stored as a Map instead of a List. This allows for much more performant updates.
The Decoration model no longer has a nested mark property. Previously a real Mark object was used as a property on decorations, but now the type and data properties are first class properties instead.
0.46 — May 1, 2019Mark operations no longer have offset or length properties. Since text nodes now contain a unique set of marks, it wouldn't make sense for a single mark-related operation to result in a splitting of nodes. Instead, when a mark is added to only part of a text node, it will result in a split_node operation as well as an add_mark operation.
Text operations no longer have a marks property. Previously it was used to add text with a specific set of marks. However this is no longer necessary, and when text is added with marks it will result in an insert_text operation as well as an add_mark operation.
Using Text.create or Text.createList with a leaves property will error. Now that text nodes no longer have leaves, you will need to pass in the text string and marks directly when creating a new text node. (However, you can still create entire values using Value.create in a backwards compatible way for convenience while migrating.)
Value.toJSON returns the new data model format, without leaves. Although Value.fromJSON and Value.create allow the old format in deprecated mode, calling Value.toJSON will return the new data format. If you still need the old one you'll need to iterate the document tree converting text nodes yourself.
The low-level Value.* and Node.* mutation methods have changed. These changes follow the operation signature changes, since the methods take the same arguments as the operations themselves. For example:
These are low-level methods, so this change shouldn't affect the majority of use cases.
Initializing editors with Text nodes with a leaves property is deprecated. In this new version of Slate, creating a new value with Value.create with the old leaf data model is still allowed for convenience in migration, but it will be removed in a coming version. (However, using the low-level Text.create will throw an error!)
0.45 — April 2, 2019A few properties of Operation objects have changed. In an effort to standardize and streamline operations, their properties have changed. This won't affect 90% of use cases, since operations are usually low-level concerns. However, if you are using operational transform or some other low-level parts of Slate, this may affect you. The value, selection, node, and mark properties—which contained references to Immutable.js objects—have all been removed. In their place, we have standardized a properties and newProperties pair. This will greatly reduce the size of operations stored in memory, and makes dealing with them easier when serialized as well.
0.44 — November 8, 2018Introducing the child_min_invalid and child_max_invalid schema errors. These new schema errors map directly to the mix and max schema rule definitions, and make it easier to determine exactly what your normalization logic needs to do to fix the document.
Added new node retrieval methods. There are three new methdos for node retrieval. The first is getNodesAtRange which will retrieve all of the nodes in the tree in a given range. And the second two are getRootBlocksAtRange and getRootInlinesAtRange for retrieving the top-most blocks or inlines in a given range. These should be helpful in defining your own command logic.
Schema errors for min and max rules have changed. Previously they would result in errors of child_required, child_object_invalid, child_type_invalid and child_unknown. Now that we have the new child_min_invalid and child_max_invalid errors, these schema rules will return them instead, making it much easier to determine exactly which rule is causing a schema error.
The getBlocksAtRange and getInlinesAtRange methods have been renamed. To clear up confusion about which blocks and inlines are retrieve in the case of nesting, these two methods have been renamed to getLeafBlocksAtRange and getLeafInlinesAtRange to clarify that they retrieve the bottom-most nodes. And now there are two additional methods called getRootBlocksAtRange and getRootInlinesAtRange for cases where you want the top-most nodes instead.
0.43 — October 27, 2018The editor.command and editor.query methods can take functions. Previously they only accepted a type string and would look up the command or query by type. Now, they also accept a custom function. This is helpful for plugin authors, who want to accept a "command option", since it gives users more flexibility to write one-off commands or queries. For example a plugin could be passed either:
Or a custom command function:
The Change object has been removed. The Change object as we know it previously has been removed, and all of its behaviors have been folded into the Editor controller. This includes the top-level commands and queries methods, as well as methods like applyOperation and normalize. All places that used to receive change now receive editor, which is API equivalent.
Changes are now flushed to onChange asynchronously. Previously this was done synchronously, which resulted in some strange race conditions in React environments. Now they will always be flushed asynchronously, just like setState.
The normalize* and validate* middleware signatures have changed! Previously the normalize* and validate* middleware was passed (node, next). However now, for consistency with the other middleware they are all passed (node, editor, next). This way, all middleware always receive editor and next as their final two arguments.
The editor.event method has been removed. Previously this is what you'd use when writing tests to simulate events being fired—which were slightly different to other running other middleware. With the simplification to the editor and to the newly-consistent middleware signatures, you can now use editor.run directly to simulate events:
The editor.change method is deprecated. With the removal of the Change object, there's no need anymore to create the small closures with editor.change(). Instead you can directly invoke commands on the editor in series, and all of the changes will be emitted asynchronously on the next tick.
The applyOperations method is deprecated. Instead you can loop a set of operations and apply each one using applyOperation. This is to reduce the number of methods exposed on the Editor to keep it simpler.
The change.call method is deprecated. Previously this was used to call a one-off function as a change method. Now this behavior is equivalent to calling editor.command(fn) instead.
0.42 — October 9, 2018Introducing the Editor controller. Previously there was a vague editor concept, that was the React component itself. This was helpful, but because it was tightly coupled to React and the browser, it didn't lend itself to non-browser use cases well. This meant that the line between "model" and "controller/view" was blurred, and some concepts lived in both places at once, in inconsistent ways.
A new Editor controller now makes this relationship clear. It borrows many of its behaviors from the React <Editor> component. And the component actually just instantiates its own plain JavaScript Editor under the covers to delegate the work to.
This new concept powers a lot of the thinking in this new version, unlocking a lot of changes that bring a clearer separation of responsibilities to Slate. It allows us to create editors in any environment, which makes server-side use cases easier, brings parity to testing, and even opens us up to supporting other view layers like React Native or Vue.js in the future.
It has a familiar API, based on the existing editor concept:
However it also introduces imperative methods to make testing easier:
I'm very excited about it, so I hope you like it!
Introducing the "commands" concept. Previously, "change methods" were treated in a first-class way, but plugins had no easy way to add their own change methods that were reusable elsewhere. And they had no way to override the built-in logic for certain commands, for example splitBlock or insertText. However, now this is all customizable by plugins, with the core Slate plugin providing all of the previous default commands.
Those commands are then available directly on the change objects, which are now editor-specific:
This allows you to define all of your commands in a single, easily-testable place. And then "behavioral" plugins can simply take command names as options, so that you have full control over the logic they trigger.
Introducing the "queries" concept. Similarly to the commands, queries allow plugins to define specific behaviors that the editor can be queried for in a reusable way, to be used when rendering buttons, or deciding on command behaviors, etc.
For example, you might define an getActiveList query:
And then be able to re-use that logic easily in different places in your codebase, or pass in the query name to a plugin that can use your custom logic itself:
Taken together, commands and queries offer a better way for plugins to manage their inter-dependencies. They can take in command or query names as options to change their behaviors, or they can export new commands and queries that you can reuse in your codebase.
The middleware stack is now deferrable. With the introduction of the Editor controller, the middleware stack in Slate has also been upgraded. Each middleware now receives a next function (similar to Express or Koa) that allows you to choose whether to iterating the stack or not.
While that may seem inconvenient, it opens up an entire new behavior, which is deferring to the plugins later in the stack to see if they "handle" a specific case, and if not, handling it yourself:
This is how all of the core logic in slate-react is now implemented, eliminating the need for a "before" and an "after" plugin that duplicate logic.
Under the covers, the schema, commands and queries concept are all implemented as plugins that attach varying middleware as well. For example, commands are processed using the onCommand middleware under the covers:
This allows you to actually listen in to all commands, and override individual behaviors if you choose to do so, without having to override the command itself. This is a very advanced feature, which most people won't need, but it shows the flexibility provided by migrating all of the previously custom internal logic to be based on the new middleware stack.
Plugins can now be defined in nested arrays. This is a small addition, but it means that you no longer need to differentiate between individual plugins and multiple plugins in an array. This allows plugins to be more easily composed up from multiple other plugins themselves, without the end user having to change how they use them. Small, but encourages reuse just a little bit more.
The slate-simulator is deprecated. Previously this was used as a pseudo-controller for testing purposes. However, now with the new Editor controller as a first-class concept, everything the simulator could do can now be done directly in the library. This should make testing in non-browser environments much easier to do.
The Value object is no longer tied to changes. Previously, you could create a new Change by calling value.change() and retrieve a new value. With the re-architecture to properly decouple the schema, commands, queries and plugins from the core Slate data models, this is no longer possible. Instead, changes are always created via an Editor instance, where those concepts live.
Sometimes this means you will need to store the React ref of the editor to be able to access its editor.change method in your React components.
Remove the Stack "model", in favor of the new Editor. Previously there was a pseudo-model called the Stack that was very low level, and not really a model. This concept has now been rolled into the new Editor controller, which can be used in any environment because it's just plain JavaScript. There was almost no need to directly use a Stack instance previously, so this change shouldn't affect almost anyone.
Remove the Schema "model", in favor of the new Editor. Previously there was another pseudo-model called the Schema, that was used to contain validation logic. All of the same validation features are still available, but the old Schema model is now rolled into the Editor controller as well, in the form of an internal SchemaPlugin that isn't exposed.
Remove the schema.isVoid and schema.isAtomic in favor of queries. Previously these two methods were used to query the schema about the behavior of a specific node or decoration. Now these same queries as possible using the "queries" concept, and are available directly on the change object:
The middleware stack must now be explicitly continued, using next. Previously returning undefined from a middleware would (usually) continue the stack onto the next middleware. Now, with middleware taking a next function argument you must explicitly decide to continue the stack by call next() yourself.
Remove the History model, in favor of commands. Previously there was a History model that stored the undo/redo stacks, and managing saving new operations to those stacks. All of this logic has been folded into the new "commands" concept, and the undo/redo stacks now live in value.data. This has the benefit of allowing the history behavior to be completely overridable by userland plugins, which was not an easy feat to manage before.
Values can no longer be normalized on creation. With the decoupling of the data model and the plugin layer, the schema rules are no longer available inside the Value model. This means that you can no longer receive a "normalized" value without having access to the Editor and its plugins.
While this seems inconvenient, it makes the boundaries in the API much more clear, and keeps the immutable and mutable concepts separated. This specific code sample gets longer, but the complexities elsewhere in the library are removed.
The Change class is no longer exported. Changes are now editor-specific, so exporting the Change class no longer makes sense. Instead, you can use the editor.change() API to receive a new change object with the commands and queries specific to your editor's plugins.
The getClosestVoid, getDecorations and hasVoidParent method now take an editor. Previously these Node methods took a schema argument, but this has been replaced with the new editor controller instead now that the Schema model has been removed.
0.41 — September 21, 2018The withoutNormalization helper has been renamed to withoutNormalizing. This is to stay consistent with the new helpers for withoutSaving and withoutMerging.
The the "operation flags" concept was removed. This was a confusing concept that was implemented in multiple different ways and led to the logic around normalizing, saving, and merging operations being more complex than it needed to be. These flags have been replaced with three simpler helper functions: withoutNormalizing, withoutSaving and withoutMerging.
This means that you no longer use the { normalize: false } or { save: false } options as arguments to individual change methods, and instead use these new helper methods to apply these behaviors to groups of changes at once.
The "normalize" change methods have been removed. Previously there were a handful of different normalization change methods like normalizeNodeByPath, normalizeParentByKey, etc. These were confusing because it put the onus on the implemented to know exact which nodes needed to be normalized. They have been removed, and implementers no longer ever need to worry about which specific nodes to normalize, as Slate will handle that for them.
The internal refindNode and refindPath methods were removed. These should never have been exposed in the first place, and are now no longer present on the Element interface. These were only used internally during the normalization process.
0.40 — August 22, 2018Remove all previously deprecated code paths. This helps to reduce some of the complexity in Slate by not having to handle these code paths anymore. And it helps to reduce file size. When upgrading, it's highly recommended that you upgrade to the previous version first and ensure there are no deprecation warnings being logged, then upgrade to this version.
0.39 — August 22, 2018Introducing the Range model and interface. Previously the "range" concept was used in multiple different places, for the selection, for decorations, and for acting on ranges of the document. This worked okay, but it was hiding the underlying system which is that Range is really an interface that other models can choose to implement. Now, we still use the Range model for referencing parts of the document, but it can also be implemented by other models that need to attach more semantic meaning...
Introducing the Decoration and Selection models. These two new models both implement the new Range interface. Where previously they had to mis-use the Range model itself with added semantics. This just cleans up some of the confusion around overlapping properties, and allows us to add even more domain-specific methods and properties in the future without trouble.
Decorations have changed! Previously, decorations piggybacked on the Range model, using the existing marks property, and introducing their own isAtomic property. However, they have now been split out into their own Decoration model with a single mark and with the isAtomic property controlled by the schema. What previously would have looked like:
Is now:
Each decoration maps to a single mark object. And the atomicity of the mark controlled in the schema instead, for example:
The Range model has reduced semantics. Previously, since all decorations and selections were ranges, you could create ranges with an isFocused, isAtomic or marks properties. Now Range objects are much simpler, offering only an anchor and a focus, and can be extended by other models implementing the range interface. However, this means that using Range.create or document.createRange might not be what you want anymore. For example, for creating a new selection, you used to use:
But now, you'll need to use document.createSelection instead:
The value.decorations property is no longer nullable. Previously when no decorations were applied to the value, the decorations property would be set to null. Now it will be an empty List object, so that the interface is more consistent.
The Node.createChildren static method is deprecated. This was just an alias for Node.createList and wasn't necessary. You can use Node.createList going forward for the same effect.
The renderPortal property of plugins is deprecated. This allows slate-react to be slightly slimmer, since this behavior can be handled in React 16 with the new <React.Fragment> using the renderEditor property instead, in a way that offers more control over the portal behavior.
The data property of plugins is deprecated. This property wasn't well designed and circumvented the core tenet that all changes to the value object will flow through operations inside Change objects. It was mostly used for view-layer state which should be handled with React-specific conventions for state management instead.
0.38 — August 21, 2018Node.isVoid access is deprecated. Previously the "voidness" of a node was hardcoded in the data model. Soon it will be determined at runtime based on your editor's schema. This deprecation just ensures that you aren't using the node.isVoid property which will not work in future verisons. What previously would have been:
Now becomes:
This requires you to have a reference to the schema object, which can be access as value.schema.
Value.isFocused/isBlurred and Value.hasUndos/hasRedos are deprecated. These properties are easily available via value.selection and value.history instead, and are now deprecated to reduce the complexity and number of different ways of doing things.
0.37 — August 3, 2018Introducing the Point model. Ranges are now built up of two Point models—an anchor and a focus—instead of having the properties set directly on the range itself. This makes the "point" concept first-class in Slate and better API's can be built around point objects.
These points are exposed on Range objects via the anchor, focus, start and end properties:
These replace the earlier anchorKey, anchorOffset, etc. properties.
Document.createRange creates a relative range. Previously you'd have to use Range.create and make sure that you passed valid arguments, and ensure that you "normalized" the range to sync its keys and paths. This is no longer the case, since the createRange method will do it for you.
This will automatically ensure that the range references leaf text nodes, and that its anchor and focus paths are set.
Document.createPoint creates a relative point. Just like the createRange method, createPoint will create a point that is guaranteed to be relative to the document itself. This is often a lot easier than using Point.create directly.
The Range.focus method was removed. (Not Change.focus!) This was necessary to make way for the new range.focus point property. Usually this would have been done in a migration-friendly way like the rest of the method changes in this release, but this was an exception. However the change.focus() method is still available and works as expected.
Range.set and Range.merge are dangerous. If you were previously using the super low-level Immutable.js methods range.set or range.merge with any of the now-removed properties of ranges, these invocations will fail. Instead, you should use the range.set* helpers going forward which can be migrated with deprecations warnings instead of failing outright.
The offset property of points defaults to null. Previously it would default to 0 but that could be confusing because it made no distinction from a "set" or "unset" offset. Now they default to null instead. This shouldn't really affect any real-world usage of Slate.
The Range.toJSON() structure has changed. With the introduction of points, the range now returns its anchor and focus properties as nested point JSON objects instead of directly as properties. For example:
The selection-based shorts on Value were deprecated. Previously you could access things like anchorKey, startOffset and isCollapsed directly on Value objects. This results in extra duplication that is hard to maintain over time, and hard for newcomers to understand, without much benefit. All of these properties are deprecated and should be accessed on the value.selection object directly instead.
The Range methods were standardized, with many deprecated. The methods on Range objects had grown drastically in size. Many of them weren't consistently named, or overlapped in unnecessary ways. With the introduction of Point objects a lot of these methods could be cleaned up and their logic delegated to the points directly. All of these methods remain available but will raise deprecation warnings, making it easier to upgrade.
Here's a full list of the newly deprecated methods and properties, and their new alternative if one exists:
The selection-based changes were standardized, with many deprecated. Similarly to the Range method deprecations, the same confusion and poor naming choices existed in the Change methods that dealt with selections. Many of them have been renamed for consistency, or deprecated when alternatives existed. All of these methods remain available but will raise deprecation warnings, making it easier to upgrade.
Here's a full list of the newly deprecated changed methods, and their new alternative if one exists:
0.36 — July 27, 2018Schema rules have changed! To make them able to be used in more cases (so you don't have to dip down to the slower validateNode/normalizeNode function), the matching syntax for schema rules has changed. Previously multiples types/objects would be expressed as:
Now there is a new match object concept, which looks like:
Match objects can be objects, or an array of objects which acts as OR:
Additionally, schema rules can now be defined using a schema.rules array of objects with top-level match properties. This allows for matching nodes in ways that were previously impossible. For example:
All of the shorthands like schema.blocks and schema.inlines are still available, and are simply rewritten to the more flexible rules syntax under the covers. These changes are just a small way of making Slate more flexible for advanced use cases when you run into them.
Schema rule normalize functions now receive SlateError objects. Previously they would be called with a signature of (change, violation, context). They are now called with (change, error). This new error is a SlateError object with an error.code and all of the same context properties.
A normalizer that previously looked like:
Would now look like:
This is just an attempt to make dealing with normalization errors slightly more idiomatic with how errors are represented in most libraries, in order to not reinvent the wheel unnecessarily.
0.35 — July 27, 2018Range objects now keep track of paths, in addition to keys. Previously ranges only stored their points as keys. Now both paths and keys are used, which allows you to choose which one is the most convenient or most performant for your use case. They are kept in sync my Slate under the covers.
A new set of *ByPath change methods have been added. All of the changes you could previously do with a *ByKey change are now also supported with a *ByPath change of the same name. The path-based changes are often more performant than the key-based ones.
Internal-yet-public Node methods have been changed. There were a handful of internal methods that shouldn't be used in 99% of Slate implementations that updated or removed. This was done in the process of streamlining many of the Node methods to make them more consistent and easier to use. For a list of those affected:
Node.assertPath was changed. It was previously confusingly named because the equivalent Node.getPath did something completely different. You should now use Node.assertNode(path) if you need this behavior.
Node.removeDescendant was removed. There's no reason you should have been using this, since it was an undocumented and unused method that was left over from a previous version.
Node.updateNode, Node.insertNode, Node.removeNode, Node.splitNode and Node.mergeNode mutating methods were changed. All of your changes should be done with operations, so you likely weren't using these internal methods. They have been changed internally to use paths.
The setKeyGenerator and resetKeyGenerator helpers are deprecated. These were previously used to change the default key generation logic. Now you can use the equivalent KeyUtils.setGenerator and KeyUtils.resetGenerator helpers instead. This follows the new pattern of grouping related utilities into single namespaces, as is the case with the new PathUtils and TextUtils.
Internal-yet-public Node methods have been deprecated. There were a handful of internal methods that shouldn't be used in 99% of Slate implementations that were deprecated. For a list of those affected:
Node.getKeys and Node.getKeysAsArray were deprecated. If you really need to check the presence of a key, use the new Node.getKeysToPathsObject instead.
Node.areDescendantsSorted and Node.isInRange were deprecated. These were used to check whether a node was in a range, but this can be done more performantly and more easily with paths now.
Node.getNodeAtPath and Node.getDescendantAtPath were deprecated. These were probably not in use by anyone, but if you were using them you can use the existing Node.getNode and Node.getDescendant methods instead which now take either paths or keys.
0.34 — June 14, 2018Decorations can now be "atomic". If you set a decoration as atomic, it will be removed when changed, preventing it from entering a "partial" state, which can be useful for some use cases.
Text nodes now represent their content as "leaves". Previously their immutable representation used individual Character instance for each character. Now they have changed to group characters into Leaf models, which more closely resembles how they are used, and results in a lot fewer immutable object instances floating around. For most people this shouldn't cause any issues, since this is a low-level aspect of Slate.
The Character model is deprecated. Although the character concept is still in the repository for now, it is deprecated and will be removed in a future release. Everything it solves can be solved with leaves instead.
0.33 — February 21, 2018Void nodes no longer prescribe their text content. Previously void nodes would automatically normalize their text content to be a single text node containing ' ' an empty string of content. This restriction was removed, so that void nodes can have arbitrary content. You can use this to store information in void nodes in a way that is more consistent with non-void nodes.
The setBlock method has been renamed to setBlocks. This is to make it more clear that it operates on any of the current blocks in the selection, not just a single blocks.
The setInline method has been renamed to setInlines. For the same reason as setBlocks, to be clear and stay consistent.
0.32 — January 4, 2018The kind property of Slate objects has been renamed to object. This is to reduce the confusion over the difference between "kind" and "type" which are practically synonyms. The "object" name was chosen to match the Stripe API, since it seems like a sensible choice and reads much more nicely when looking through JSON.
All normalization reasons containing kind have been renamed too. Previously there were normalization reason strings like child_kind_invalid. These types of strings have been renamed to child_object_invalid to stay consistent.
0.31 — November 16, 2017Added a new Operation model. This model is used to store operations for the history stack, and (de)serializes them in a consistent way for collaborative editing use cases.
Operation objects in Slate are now immutable records. Previously they were native, mutable JavaScript objects. Now, there's a new immutable Operation model in Slate, ensuring that all of the data inside Value objects are immutable. And it allows for easy serialization of operations using operation.toJSON() for when sending them between editors. This should not affect most users, unless you are relying on changing the values of the low-level Slate operations (simply reading them is fine).
Operation lists in Slate are now immutable lists. Previously they were native, mutable JavaScript arrays. Now, to keep consistent with other immutable uses, they are immutable lists. This should not affect most users.
0.30 — October 27, 2017Remove all previously deprecated code paths. This helps to reduce some of the complexity in Slate by not having to handle these code paths anymore. And it helps to reduce file size. When upgrading, it's highly recommended that you upgrade to the previous version first and ensure there are no deprecation warnings being logged, then upgrade to this version.
0.29 — October 27, 2017Added the new Value model to replace State. The new model is exactly the same, but with a new name. There is also a shimmed State model exported that warns when used, to ease migration.
The set_state operation has been renamed set_value. This shouldn't affect almost anyone, but in the event that you were relying on the low-level operation types you'll need to update this.
The "state" has been renamed to "value" everywhere. All of the current references are maintained as deprecations, so you should be able to upgrade and see warnings logged instead of being greeted with a broken editor. This is to reduce the confusion between React's "state" and Slate's editor value, and in an effort to further mimic the native DOM APIs.
0.28 — October 25, 2017State objects now have an embedded state.schema property. This new schema property is used to automatically normalize the state as it changes, according to the editor's current schema. This makes normalization much easier.
The Schema objects in Slate have changed! Previously, they used to be where you could define normalization rules, define rendering rules, and define decoration rules. This was overloaded, and made other improvements hard. Now, rendering and decorating is done via the newly added plugin functions (renderNode, renderMark, decorateNode). And validation is done either via the lower-level validateNode plugin function, or via the new schema objects.
The normalize* change methods no longer take a schema argument. Previously you had to maintain a reference to your schema, and pass it into the normalize methods when you called them. Since State objects now have an embedded state.schema property, this is no longer needed.
0.27 — October 14, 2017The Range model is now called Leaf. This is to disambiguate with the concept of "ranges" that is used throughout the codebase to be synonymous to selections. For example in methods like getBlocksAtRange(selection).
The text.ranges property in the JSON representation is now text.leaves. When passing in JSON with text.ranges you'll now receive a deprecation warning in the console in development.
The Selection model is now called Range. This is to make it more clear what a "selection" really is, to make many of the other methods that act on "ranges" make sense, and to more closely parallel the native DOM API for selections and ranges. A mock Selection object is still exported with deprecated static methods, to make the transition to the new API easier.
The Text.getRanges() method is now Text.getLeaves(). It will still work, and it will return a list of leaves, but you will see a deprecation warning in the console in development.
0.26 — October 13, 2017The set_data operation type has been replaced by set_state. With the new state.decorations property, it doesn't make sense to have a new operation type for every property of State objects. Instead, the new set_state operation more closely mimics the existing set_mark and set_node operations.
The setData change method has been replaced by setState. Previously you would call change.setData(data). But as new State properties are introduced it doesn't make sense to need to add new change methods each time. Instead, the new change.setState(properties) more closesely mimics the existing setMarkByKey and setNodeByKey. To achieve the old behavior, you can do change.setState({ data }).
The preserveStateData option of state.toJSON has changed. The same behavior is now called preserveData instead. This makes it consistent with all of the existing options, and the new preserveDecorations option as well.
0.25 — September 21, 2017The insertBlock change method no longer replaces empty blocks. Previously if you used insertBlock and the selection was in an empty block, it would replace it. Now you'll need to perform that check yourself and use the new replaceNodeByKey method instead.
The Block.create and Inline.create methods no longer normalize. Previously if you used one of them to create a block or inline with zero nodes in it, they would automatically add a single empty text node as the only child. This was unexpected in certain situations, and if you were relying on this you'll need to handle it manually instead now.
0.24 — September 11, 2017Slate is now a "monorepo". Instead of a single package, Slate has been divided up into individual packages so that you can only require what you need, cutting down on file size. In the process, some helpful modules that used to be internal-only are now exposed.
The slate-prop-types package is now exposed. Previously this was an internal module, but now you can use it for adding prop types to any components or plugins you create.
The slate-simulator package is now exposed. Previously this was an internal testing utility, but now you can use it in your own tests as well. It's currently pretty bare bones, but we can add to it over time.
immutable is now a peer dependency of Slate. Previously it was a regular dependency, but this prevented you from bringing your own version, or you'd have duplication. You'll need to ensure you install it!
The Html, Plain and Raw serializers are broken into new packages. Previously you'd import them from slate. But now you'll import them from slate-html-serializer and slate-plain-serializer. And the Raw serializer that was deprecated is now removed.
The Editor and Placeholder components are broken into a new React-specific package. Previously you'd import them from slate. But now you import { Editor } from 'slate-react' instead.
0.23 — September 10, 2017Slate models now have Model.fromJSON(object) and model.toJSON() methods. These methods operate with the canonical JSON form (which used to be called "raw"). This way you don't need to import a serializer to retrieve JSON, if you have the model you can serialize/deserialize.
Models also have toJS and fromJS aliases. This is just to match Immutable.js objects, which have both methods. For Slate though, the methods are equivalent.
The isNative property of State has been removed. Previously this was used for performance reasons to avoid re-rendering, but it is no longer needed. This shouldn't really affect most people because it's rare that you'd be relying on this property to exist.
The Raw serializer is now deprecated. The entire "raw" concept is being removed, in favor of allowing all models to be able to serialize and deserialize to JSON themselves. Instead of using the Raw serializer, you can now use the fromJSON and toJSON on the models directly.
The toRaw options for the Plain and Html serializers are now called toJSON. This is to stay symmetrical with the removal of the "raw" concept everywhere.
The terse option for JSON serialization has been deprecated! This option causes lots of abstraction leakiness because it means there is no one canonical JSON representation of objects. You had to work with either terse or not terse data.
The Html serializer no longer uses the terse representation. This shouldn't actually be an issue for anyone because the main manifestation of this has a deprecation notice with a patch in place for now.
The defaultBlockType of the Html serializer is now called defaultBlock. This is just to make it more clear that it supports not only setting the default type but also data and isVoid.
0.22 — September 5, 2017The state.activeMarks returns the intersection of marks in the selection. Previously there was only state.marks which returns marks that appeared on any character in the selection. But state.activeMarks returns marks that appear on every character in the selection, which is often more useful for implementing standard richtext editor behaviors.
The Plain serializer now adds line breaks between blocks. Previously between blocks the text would be joined without any space whatsoever, but this wasn't really that useful or what you'd expect.
The toggleMark transform now checks the intersection of marks. Previously, toggling would remove the mark from the range if any of the characters in a range didn't have it. However, this wasn't what all other richtext editors did, so the behavior has changed to mimic the standard behavior. Now, if any characters in the selection have the mark applied, it will first be added when toggling.
The .length property of nodes has been removed. This property caused issues with code like in Lodash that checked for "array-likeness" by simply looking for a .length property that was a number.
onChange now receives a Change object (previously named Transform) instead of a State. This is needed because it enforces that all changes are represented by a single set of operations. Otherwise right now it's possible to do things like state.transform()....apply({ save: false }).transform()....apply() and result in losing the operation information in the history. With OT, we need all transforms that may happen to be exposed and emitted by the editor. The new syntax looks like:
Similarly, handlers now receive e, data, change instead of e, data, state. Instead of doing return state.transform()....apply() the plugins can now act on the change object directly. Plugins can still return change... if they want to break the stack from continuing on to other plugins. (Any != null value will break out.) But they can also now not return anything, and the stack will apply their changes and continue onwards. This was previously impossible. The new syntax looks like:
The onChange and on[Before]Change handlers now receive Change objects. Previously they would also receive a state object, but now they receive change objects like the rest of the plugin API.
The .apply({ save }) option is now state.change({ save }) instead. This is the easiest way to use it, but requires that you know whether to save or not up front. If you want to use it inline after already saving some changes, you can use the change.setOperationFlag('save', true) flag instead. This shouldn't be necessary for 99% of use cases though.
The .undo() and .redo() transforms don't save by default. Previously you had to specifically tell these transforms not to save into the history, which was awkward. Now they won't save the operations they're undoing/redoing by default.
onBeforeChange is no longer called from componentWillReceiveProps, when a new state is passed in as props to the <Editor> component. This caused lots of state-management issues and was weird in the first place because passing in props would result in changes firing. It is now the parent component's responsibility to not pass in improperly formatted State objects.
The splitNodeByKey change method has changed to be shallow. Previously, it would deeply split to an offset. But now it is shallow and another splitDescendantsByKey change method has been added (with a different signature) for the deep splitting behavior. This is needed because splitting and joining operations have been changed to all be shallow, which is required so that operational transforms can be written against them.
Blocks cannot have mixed "inline" and "block" children anymore. Blocks were implicitly expected to either contain "text" and "inline" nodes only, or to contain "block" nodes only. Invalid case are now normalized by the core schema.
The shape of many operations has changed. This was needed to make operations completely invertible without any extra context. The operations were never really exposed in a consumable way, so I won't detail all of the changes here, but feel free to look at the source to see the details.
All references to "joining" nodes is now called "merging". This is to be slightly clearer, since merging can only happen with adjacent nodes already, and to have a nicer parallel with "splitting", as in cells. The operation is now called merge_node, and the transforms are now merge*.
The transform.apply() method is deprecated. Previously this is where the saving into the history would happen, but it created an awkward convention that wasn't necessary. Now operations are saved into the history as they are created with change methods, instead of waiting until the end. You can access the new State of a change at any time via change.state.
0.21 — July 20, 2017The Html serializer now uses DOMParser instead of cheerio. Previously, the Html serializer used the cheerio library for representing elements in the serialization rule logic, but cheerio was a very large dependency. It has been removed, and the native browser DOMParser is now used instead. All HTML serialization rules will need to be updated. If you are working with Slate on the server, you can now pass in a custom serializer to the Html constructor, using the parse5 library.
0.20 — May 17, 2017Returning null from the Html serializer skips the element. Previously, null and undefined had the same behavior of skipping the rule and trying the rest of the rules. Now if you explicitly return null it will skip the element itself.
0.19 — March 3, 2017The filterDescendants and findDescendants methods are now depth-first. This shouldn't affect almost anyone, since they are usually not the best things to be using for performance reasons. If you happen to have a very specific use case that needs breadth-first, (or even likely something better), you'll need to implement it yourself.
Some Node methods have been deprecated! There were a few methods that had been added over time that were either poorly named that have been deprecated and renamed, and a handful of methods that are no longer useful for the core library that have been deprecated. Here's a full list:
areDescendantSorted -> areDescendantsSorted
getHighestChild -> getFurthestAncestor
getHighestOnlyChildParent -> getFurthestOnlyChildAncestor
concatChildren
decorateTexts
filterDescendantsDeep
findDescendantDeep
getChildrenBetween
getChildrenBetweenIncluding
isInlineSplitAtRange
0.18 — March 2, 2017The plugin.render property is now called plugin.renderPortal. This is to make way for the new plugin.render property that offers HOC-like behavior, so that plugins can augment the editor however they choose.
0.17 — February 27, 2017Some Selection methods have been deprecated! Previously there were many inconsistencies in the naming and handling of selection changes. This has all been cleaned up, but in the process some methods have been deprecated. Here is a full list of the deprecated methods and their new alternatives:
moveToOffsets -> moveOffsetsTo
moveForward -> move
moveBackward -> move
moveAnchorOffset -> moveAnchor
moveFocusOffset -> moveFocus
moveStartOffset -> moveStart
moveEndOffset -> moveEnd
extendForward -> extend
extendBackward -> extend
unset -> deselect
Some selection transforms have been deprecated! Along with the methods, the selection-based transforms have also been refactored, resulting in deprecations. Here is a full list of the deprecated transforms and their new alternatives:
moveTo -> select
moveToOffsets -> moveOffsetsTo
moveForward -> move
moveBackward -> move
moveStartOffset -> moveStart
moveEndOffset -> moveEnd
extendForward -> extend
extendBackward -> extend
flipSelection -> flip
unsetSelection -> deselect
unsetMarks
0.16 — December 2, 2016Inline nodes are now always surrounded by text nodes. Previously this behavior only occured for inline nodes with isVoid: true. Now, all inline nodes will always be surrounded by text nodes. If text nodes don't exist, empty ones will be created. This allows for more consistent behavior across Slate, and parity with other editing experiences.
0.15 — November 17, 2016The unique key generated values have changed. Previously, Slate generated unique keys that looked like '9dk3'. But they were not very conflict-resistant. Now the keys are simple string of auto-incrementing numbers, like '0', '1', '2'. This makes more clear that keys are simply a convenient way to uniquely reference nodes in the short-term lifespan of a single in-memory instance of Slate. They are not designed to be used for long-term uniqueness. A new setKeyGenerator function has been exported that allows you to pass in your own key generating mechanism if you want to ensure uniqueness.
The Raw serializer doesn't preserve keys by default. Previously, the Raw serializer would omit keys when passed the terse: true option, but preserve them without it. Now it will always omit keys, unless you pass the new preserveKeys: true option. This better reflects that keys are temporary, in-memory IDs.
Operations on the document now update the selection when needed. This won't affect you unless you were doing some very specific things with transforms and updating selections. Overall, this makes it much easier to write transforms, since in most cases, the underlying operations will update the selection as you would expect without you doing anything.
Node accessor methods no longer accept being passed another node! Previously, node accessor methods like node.getParent could be passed either a key string or a node object. For performance reasons, passing in a node object is being deprecated. So if you have any calls that look like: node.getParent(descendant), they will now need to be written as node.getParent(descendant.key). They will throw a warning for now, and will throw an error in a later version of Slate.
0.14 — September 10, 2016The undo and redo transforms need to be applied! Previously, undo and redo were special cased such that they did not require an .apply() call, and instead would return a new State directly. Now this is no longer the case, and they are just like every other transform.
Transforms are no longer exposed on State or Node. The transforms API has been completely refactored to be built up of "operations" for collaborative editing support. As part of this refactor, the transforms are now only available via the state.transform() API, and aren't exposed on the State or Node objects as they were before.
The selection can now be "unset". Previously, a selection could never be in an "unset" state where the anchorKey or focusKey was null. This is no longer technically true, although this shouldn't really affect anyone in practice.
0.13 — August 15, 2016The renderDecorations property is gone! Decoration rendering has also been replaced by the new schema property of the <Editor>.
0.12 — August 9, 2016The data.files property is now an Array. Previously it was a native FileList object, but needed to be changed to add full support for pasting an dropping files in all browsers. This shouldn't affect you unless you were specifically depending on it being array-like instead of a true Array.
0.11 — August 4, 2016Void nodes are renderered implicitly again! Previously Slate had required that you wrap void node renderers yourself with the exposed <Void> wrapping component. This was to allow for selection styling, but a change was made to make selection styling able to handled in JavaScript. Now the <Void> wrapper will be implicitly rendered by Slate, so you do not need to worry about it, and "voidness" only needs to toggled in one place, the isVoid: true property of a node.
0.10 — July 29, 2016Marks are now renderable as components. Previously the only supported way to render marks was by returning a style object. Now you can return a style object, a class name string, or a full React component. Because of this, the DOM will be renderered slightly differently than before, resulting in an extra <span> when rendering non-component marks. This won't affect you unless you were depending on the DOM output by Slate for some reason.
0.9 — July 28, 2016The wrap and unwrap method signatures have changed! Previously, you would pass type and data as separate parameters, for example: wrapBlock('code', { src: true }). This was inconsistent with other transforms, and has been updated such that a single argument of properties is passed instead. So that example could now be: wrapBlock({ type: 'code', { data: { src: true }}). You can still pass a type string as shorthand, which will be the most frequent use case, for example: wrapBlock('code').
0.8 — July 27, 2016The onKeyDown and onBeforeInput handlers signatures have changed! Previously, some Slate handlers had a signature of (e, state, editor) and others had a signature of (e, data, state, editor). Now all handlers will be passed a data object—which contains Slate-specific data related to the event—even if it is empty. This is helpful for future compatibility where we might need to add data to a handler that previously didn't have any, and is nicer for consistency. The onKeyDown handler's new data object contains the key name, code and a series of is* properties to make working with hotkeys easier. The onBeforeInput handler's new data object is empty.
The Utils export has been removed. Previously, a Key utility and the findDOMNode utility were exposed under the Utils object. The Key has been removed in favor of the data object passed to onKeyDown. And then findDOMNode utility has been upgraded to a top-level named export, so you'll now need to access it via import { findDOMNode } from 'slate'.
Void nodes now permanently have " " as content. Previously, they contained an empty string, but this isn't technically correct, since they have content and shouldn't be considered "empty". Now they will have a single space of content. This shouldn't really affect anyone, unless you happened to be accessing that string for serialization.
Empty inline nodes are now impossible. This is to stay consistent with native contenteditable behavior, where although technically the elements can exist, they have odd behavior and can never be selected.
0.7 — July 24, 2016The Raw serializer is no longer terse by default! Previously, the Raw serializer would return a "terse" representation of the document, omitting information that wasn't strictly necessary to deserialize later, like the key of nodes. By default this no longer happens. You have to opt-in to the behavior by passing { terse: true } as the second options argument of the deserialize and serialize methods.
0.6 — July 22, 2016data-offset-key is now <key>-<index> instead of <key>:<start>-<end>. This shouldn't actually affect anyone, unless you were specifically relying on that attribute in the DOM. This change greatly reduces the number of re-renders needed, since previously any additional characters would cause a cascading change in the <start> and <end> offsets of latter text ranges.
0.5 — July 20, 2016Node methods now throw earlier during unexpected states. This shouldn't break anything for most folks, unless a strange edge-case was going undetected previously.
0.4 — July 20, 2016renderMark(mark, state, editor) is now renderMark(mark, marks, state, editor). This change allows you to render marks based on multiple marks presence at once on a given range of text, for example using a custom BoldItalic.otf font when text has both bold and italic marks.
0.3 — July 20, 2016transform.unwrapBlock() now unwraps selectively. Previously, calling unwrapBlock with a range representing a middle sibling would unwrap all of the siblings, removing the wrapping block entirely. Now, calling it with those same arguments will only move the middle sibling up a layer in the hierarchy, preserving the nesting on any of its siblings. This changes makes it much simpler to implement functionality like unwrapping a single list item, which previously would unwrap the entire list.
0.2 — July 18, 2016transform.mark() is now transform.addMark() and transform.unmark() is now transform.removeMark(). The new names make it clearer that the transforms are actions being performed, and it paves the way for adding a toggleMark convenience as well.
0.1 — July 13, 2016A complete overhaul. The Slate codebase has had a complete overhaul and many pieces of its core architecture have been reconsidered from the ground up. There are lots of changes. We recommend re-reading the and documentation and the to get a sense for everything that has changed. As well as the writeup for what the major changes are.
There's a very good chance you're only using a handful of them in your codebase. Either way, all of them will log warnings. For an example of migrating see .
There's a very good chance you're only using a handful of these change methods in your codebase. Either way, all of them will log warnings. For an example of migrating see .
Paths are now of type instead of array. See the documentation of for its differences to array (get method instead of array indexing, size instead of length, etc).
The decorate function of schema rules has changed. Previously, in decorate you would receive a text node and the matched node, and you'd need to manually add any marks you wanted to the text node's characters. Now, "decorations" have changed to just be Selection objects with marks in the selection.marks property. Instead of applying the marks yourself, you simply return selection ranges with the marks to be applied, and Slate will apply them internally. This makes it possible to write much more complex decoration behaviors. Check out the revamped example and the new example to see this in action.
You can now set decorations based on external information. Previously, the "decoration" logic in Slate was always based off of the text of a node, and would only re-render when that text changed. Now, there is a new state.decorations property that you can set via change.setState({ decorations }). You can use this to add presentation-only marks to arbitrary ranges of text in the document. Check out the new example to see this in action.
There's a new slate-hyperscript helper. This was possible thanks to the work on , which paved the way.
Transform objects are now mutable. Previously Transform was an Immutable.js Record, but now it is a simple constructor. This is because transforms are inherently mutating their representation of a state, but this decision is .
The renderNode and renderMark properties are gone! Previously, rendering nodes and marks happened via these two properties of the <Editor>, but this has been replaced by the new schema property. Check out the updated examples to see how to define a schema! There's a good chance this eliminates extra code for most use cases!
Void components are no longer rendered implicity! Previously, Slate would automatically wrap any node with isVoid: true in a <Void> component. But doing this prevented you from customizing the wrapper, like adding a className or style property. So you must now render the wrapper yourself, and it has been exported as Slate.Void. This, combined with a small change to the <Void> component's structure allows the "selected" state of void nodes to be rendered purely with CSS based on the :focus property of a <Void> element, which previously . This allows us to streamline selection-handling logic, improving performance and reducing complexity.
node.getTextNodes() is now node.getTexts(). This is just for consistency with the other existing Node methods like getBlocks(), getInlines(), etc. And it's nicely shorter.
