Reporting Bugs

If you run into any weird behavior while using Slate, feel free to open a new issue in this repository! Please run a search before opening a new issue, to make sure that someone else hasn't already reported or solved the bug you've found.

Any issue you open must include:

  • A JSFiddle that reproduces the bug with a minimal setup.

  • A GIF showing the issue in action. (Using something like RecordIt.)

  • A clear explanation of what the issue is.

Here's a JSFiddle template for Slate to get you started:

Asking Questions

We've also got a Slate Slack team where you can ask questions and get answers from other people using Slate:

Please use the Slack instead of asking questions in issues, since we want to reserve issues for keeping track of bugs and features. We close questions in issues so that maintaining the project isn't overwhelming.

Submitting Pull Requests

All pull requests are super welcomed and greatly appreciated! Issues in need of a solution are marked with a ♥ help please label if you're looking for somewhere to start.

Please include tests and docs with every pull request!

Running Examples

Check out the Examples readme to see how to get the examples running locally!

Running Tests

To run the tests, you need to have the Slate repository cloned to your computer. After that, you need to cd into the directory where you cloned it, and install the dependencies with yarn and build the monorepo:

yarn install
yarn build

Then run the tests with:

yarn test

To keep the source rebuilding on every file change, you need to run an additional watching command in a separate process:

yarn watch

If you need to debug something, you can add a debugger line to the source, and then run yarn test debug.

If you only want to run a specific test or tests, you can run yarn test --fgrep="slate-react rendering" flag which will filter the tests being run by grepping for the string in each test.

Running Benchmarks

To run the benchmarks, first make some changes to the source that you want to benchmark. Now that you're ready, you need to save a "baseline" for what the performance was before you made you change.

To do that, stash your changes and save the benchmarks:

git stash
yarn benchmark:save

Then once the reference has been saved, unstash your changes and run the benchmarks to see a comparison:

git stash pop
yarn benchmark

There will be some subtle changes in iteration speed always, but the comparison reporter will highlight any changes that seem meaningful. You can run benchmark multiple times to ensure the speed up persists.

Run Selected Benchmarks

To run selected benchmarks, create tmp/benchmark-config.js with module.exports.include. For example, to run slate-core benchmarks only with get-*, we can create a tmp/benchmark-config.js as

module.exports.include = {
  slate: /^get/

Adding Browser Support

Slate aims to targeted all of the modern browsers, and eventually the modern mobile platforms. Right now browser support is limited to the latest versions of Chrome, Firefox, and Safari, but if you are interested in adding support for another modern platform, that is welcomed!

Testing Input Methods

Here's a helpful page detailing how to test various input scenarios on Windows, Mac and Linux.

Debugging Slate Methods

Slate makes use of debug to log information about various methods. You can enable the logger in the browser by setting localStorage.debug = "*" (to log methods on all modules) or to a single namespace (e.g. slate:editor). Look for const debug = Debug('<namespace>') to get the namespace of various modules.

Publishing Releases

Since we use Lerna to manage the Slate packages this is fairly easy, but you must make sure you are using npm to run the release script, because using yarn results in failures. So just run:

npm run release

And follow the prompts Lerna gives you.
