This module allows you to create and use standalone block editors.
Install the module
npm install @wordpress/block-editor --saveThis package assumes that your code will run in an ES2015+ environment. If you're using an environment that has limited or no support for such language features and APIs, you should include the polyfill shipped in @wordpress/babel-preset-default in your code.
import { useState } from 'react';
import {
BlockCanvas,
BlockEditorProvider,
BlockList,
} from '@wordpress/block-editor';
function MyEditorComponent() {
const [ blocks, updateBlocks ] = useState( [] );
return (
<BlockEditorProvider
value={ blocks }
onInput={ ( blocks ) => updateBlocks( blocks ) }
onChange={ ( blocks ) => updateBlocks( blocks ) }
>
<BlockCanvas height="400px" />
</BlockEditorProvider>
);
}
// Make sure to load the block editor stylesheets too
// import '@wordpress/components/build-style/style.css';
// import '@wordpress/block-editor/build-style/style.css';In this example, we're instantiating a block editor. A block editor is composed by a BlockEditorProvider wrapper component where you pass the current array of blocks and on each change the onInput or onChange callbacks are called depending on whether the change is considered persistent or not.
Inside BlockEditorProvider, you can nest any of the available @wordpress/block-editor UI components to build the UI of your editor.
In the example above we're rendering the BlockList to show and edit the block list. For instance we could add a custom sidebar and use the BlockInspector component to be able to edit the advanced settings for the currently selected block. (See the API for the list of all the available components).
The BlockTools component is used to render the toolbar for a selected block.
In the example above, there's no registered block type, in order to use the block editor successfully make sure to register some block types. For instance, registering the core block types can be done like so:
import { registerCoreBlocks } from '@wordpress/block-library';
registerCoreBlocks();
// Make sure to load the block stylesheets too
// import '@wordpress/block-library/build-style/style.css';
// import '@wordpress/block-library/build-style/editor.css';
// import '@wordpress/block-library/build-style/theme.css';Any components in this package that have a counterpart in @wordpress/components are an extension of those components.
Unless you're creating an editor, it is recommended that the components in @wordpress/components should be used rather than the ones in this package as these components have been customized for use in an editor and may result in unexpected behaviour if used outside of this context.

BlockCanvas component is a component used to display the canvas of the block editor. What we call the canvas is an iframe containing the block list that you can manipulate. The component is also responsible of wiring up all the necessary hooks to enable the keyboard navigation across blocks in the editor and inject content styles into the iframe.
Usage
function MyBlockEditor() {
const [ blocks, updateBlocks ] = useState( [] );
return (
<BlockEditorProvider
value={ blocks }
onInput={ updateBlocks }
onChange={ persistBlocks }
>
<BlockCanvas height="400px" />
</BlockEditorProvider>
);

props
Object: Component props. -
props.height
string: Canvas height, defaults to 300px. -

Changelog
6.7.0 Introduced in WordPress core.
Undocumented declaration.
Hook used to try to find a matching block variation and return the appropriate information for display reasons. In order to to try to find a match we need to things: 1. Block's client id to extract it's current attributes. 2. A block variation should have set isActive prop to a proper function.
If for any reason a block variation match cannot be found, the returned information come from the Block Type. If no blockType is found with the provided clientId, returns null.
Parameters
-
clientId
string: Block's client id.
Returns
-
?WPBlockDisplayInformation: Block's display information, ornullwhen the block or its type not found.
The useBlockEditContext hook provides information about the block this hook is being used in. It returns an object with the name, isSelected state, and the clientId of the block. It is useful if you want to create custom hooks that need access to the current blocks clientId but don't want to rely on the data getting passed in as a parameter.
Returns
-
Object: Block edit context
Allows a block to restrict the user interface that is displayed for editing that block and its inner blocks.
Usage
function MyBlock( { attributes, setAttributes } ) {
useBlockEditingMode( 'disabled' );
return <div { ...useBlockProps() }></div>;
}mode can be one of three options:
-
'disabled': Prevents editing the block entirely, i.e. it cannot be selected. -
'contentOnly': Hides all non-content UI, e.g. auxiliary controls in the toolbar, the block movers, block settings. -
'default': Allows editing the block as normal.
The mode is inherited by all of the block's inner blocks, unless they have their own mode.
If called outside of a block context, the mode is applied to all blocks.
Parameters
-
mode
?BlockEditingMode: The editing mode to apply. If undefined, the current editing mode is not changed.
Returns
-
BlockEditingMode: The current editing mode.
This hook is used to lightly mark an element as a block element. The element should be the outermost element of a block. Call this hook and pass the returned props to the element to mark as a block. If you define a ref for the element, it is important to pass the ref to this hook, which the hook in turn will pass to the component through the props it returns. Optionally, you can also pass any other props through this hook, and they will be merged and returned.
Use of this hook on the outermost element of a block is required if using API >= v2.
Usage
import { useBlockProps } from '@wordpress/block-editor';
export default function Edit() {
const blockProps = useBlockProps( {
className: 'my-custom-class',
style: {
color: '#222222',
backgroundColor: '#eeeeee',
},
} );
return <div { ...blockProps }></div>;
}Parameters
-
props
Object: Optional. Props to pass to the element. Must contain the ref if one is defined. -
options
Object: Options for internal use only. -
options.__unstableIsHtml
boolean:
Returns
-
Object: Props to pass to the element to mark as a block.

A React hook for keeping track of blocks previously rendered up in the block tree. Blocks susceptible to recursion can use this hook in their Edit function to prevent said recursion.
Use this with the RecursionProvider component, using the same uniqueId value for both the hook and the provider.
Parameters
-
uniqueId
*: Any value that acts as a unique identifier for a block instance. -
blockName
string: Optional block name.
Returns
-
boolean: A boolean describing whether the provided id has already been rendered.
This hook is used to lightly mark an element as an inner blocks wrapper element. Call this hook and pass the returned props to the element to mark as an inner blocks wrapper, automatically rendering inner blocks as children. If you define a ref for the element, it is important to pass the ref to this hook, which the hook in turn will pass to the component through the props it returns. Optionally, you can also pass any other props through this hook, and they will be merged and returned.

Parameters
-
props
Object: Optional. Props to pass to the element. Must contain the ref if one is defined. -

Usage
export default compose(
withColors( 'backgroundColor', { textColor: 'color' } ),
MyColorfulComponent
);Parameters
-
colorTypes
...(Object|string): The arguments can be strings or objects. If the argument is an object, it should contain the color attribute name as key and the color context as value. If the argument is a string the value should be the color attribute name, the color context is computed by applying a kebab case transform to the value. Color context represents the context/place where the color is going to be used. The class name of the color is generated using 'has' followed by the color name and ending with the color context all in kebab case e.g: has-green-background-color.

-
Function: Higher-order component.
Higher-order component, which handles font size logic for class generation, font size value retrieval, and font size change handling.

Returns
-
Function: Higher-order component.
