# Node `Node` is not a publicly accessible module, but instead an interface that [`Document`](https://docs.slatejs.org/v0.47/slate-core/document), [`Block`](https://docs.slatejs.org/v0.47/slate-core/block) and [`Inline`](https://docs.slatejs.org/v0.47/slate-core/inline) all implement. ## Properties ### `key` `String` A short-lived, unique identifier for the node. By default, keys are **not** meant to be long-lived unique identifiers for nodes that you might store in a database, or elsewhere. They are meant purely to identify a node inside of a single Slate instance. For that reason, they are simply auto-incrementing strings. (eg. `'0'`, `'1'`, `'2'`, ...) If you want to make your keys uniqueness long-lived, you'll need to supply your own key generating function via the [`setKeyGenerator`](https://docs.slatejs.org/v0.47/utils#setkeygenerator) util. ### `nodes` `Immutable.List` A list of child nodes. Defaults to a list with a single text node child. ### `object` `String` An immutable string value of `'document'`, `'block'`, `'inline'` or `'text'` for easily separating this node from [`Inline`](https://docs.slatejs.org/v0.47/slate-core/inline) or [`Text`](https://docs.slatejs.org/v0.47/slate-core/text) nodes. ## Computed Properties ### `text` `String` A concatenated string of all
