What is draft-js?
Draft.js is a JavaScript rich text editor framework, built for React. It provides a set of immutable models and helper functions for creating rich text editors with a high degree of customization and control over the content and behavior.
What are draft-js's main functionalities?
Creating a Basic Editor
This code demonstrates how to create a basic rich text editor using Draft.js. It initializes an empty editor state and renders the editor component.
import React from 'react';
import { Editor, EditorState } from 'draft-js';
import 'draft-js/dist/Draft.css';
class MyEditor extends React.Component {
constructor(props) {
super(props);
this.state = { editorState: EditorState.createEmpty() };
this.onChange = (editorState) => this.setState({ editorState });
}
render() {
return (
<Editor editorState={this.state.editorState} onChange={this.onChange} />
);
}
}
export default MyEditor;
Handling Text Formatting
This code demonstrates how to handle text formatting commands in Draft.js. It uses the `RichUtils.handleKeyCommand` method to apply formatting like bold, italic, etc., based on keyboard shortcuts.
import React from 'react';
import { Editor, EditorState, RichUtils } from 'draft-js';
import 'draft-js/dist/Draft.css';
class MyEditor extends React.Component {
constructor(props) {
super(props);
this.state = { editorState: EditorState.createEmpty() };
this.onChange = (editorState) => this.setState({ editorState });
this.handleKeyCommand = this.handleKeyCommand.bind(this);
}
handleKeyCommand(command, editorState) {
const newState = RichUtils.handleKeyCommand(editorState, command);
if (newState) {
this.onChange(newState);
return 'handled';
}
return 'not-handled';
}
render() {
return (
<Editor
editorState={this.state.editorState}
handleKeyCommand={this.handleKeyCommand}
onChange={this.onChange}
/>
);
}
}
export default MyEditor;
Custom Block Rendering
This code demonstrates how to implement custom block rendering in Draft.js. It defines a custom block renderer function and a custom block component to render specific types of content blocks.
import React from 'react';
import { Editor, EditorState, ContentBlock } from 'draft-js';
import 'draft-js/dist/Draft.css';
function myBlockRenderer(contentBlock) {
const type = contentBlock.getType();
if (type === 'atomic') {
return {
component: MyCustomBlockComponent,
editable: false,
};
}
}
class MyCustomBlockComponent extends React.Component {
render() {
return <div>My Custom Block</div>;
}
}
class MyEditor extends React.Component {
constructor(props) {
super(props);
this.state = { editorState: EditorState.createEmpty() };
this.onChange = (editorState) => this.setState({ editorState });
}
render() {
return (
<Editor
editorState={this.state.editorState}
onChange={this.onChange}
blockRendererFn={myBlockRenderer}
/>
);
}
}
export default MyEditor;
Other packages similar to draft-js
slate
Slate is a completely customizable framework for building rich text editors. Unlike Draft.js, which provides a more opinionated structure, Slate offers more flexibility and control over the editor's behavior and appearance. It uses a more modern approach with a focus on immutability and functional programming.
quill
Quill is a powerful, rich text editor that provides a wide range of features out of the box. It is more feature-rich and easier to set up compared to Draft.js, but it offers less flexibility for customization and control over the editor's internals.
prosemirror
ProseMirror is a toolkit for building rich text editors with a focus on extensibility and customizability. It provides a more modular approach compared to Draft.js, allowing developers to build complex editors with custom behaviors and features.
Draft.js is a JavaScript rich text editor framework, built for React and
backed by an immutable model.
- Extensible and Customizable: We provide the building blocks to enable
the creation of a broad variety of rich text composition experiences, from
simple text styles to embedded media.
- Declarative Rich Text: Draft.js fits seamlessly into
React applications,
abstracting away the details of rendering, selection, and input behavior with a
familiar declarative API.
- Immutable Editor State: The Draft.js model is built
with immutable-js, offering
an API with functional state updates and aggressively leveraging data persistence
for scalable memory usage.

API Notice
Before getting started, please be aware that we recently changed the API of
Entity storage in Draft. The latest version, v0.10.0
, supports both the old
and new API. Following that up will be v0.11.0
which will remove the old API.
If you are interested in helping out, or tracking the progress, please follow
issue 839.
Getting Started
Currently Draft.js is distributed via npm. It depends on React and React DOM which must also be installed.
npm install --save draft-js react react-dom
or
yarn add draft-js react react-dom
Using Draft.js
import React from 'react';
import ReactDOM from 'react-dom';
import {Editor, EditorState} from 'draft-js';
class MyEditor extends React.Component {
constructor(props) {
super(props);
this.state = {editorState: EditorState.createEmpty()};
this.onChange = (editorState) => this.setState({editorState});
this.setEditor = (editor) => {
this.editor = editor;
};
this.focusEditor = () => {
if (this.editor) {
this.editor.focus();
}
};
}
componentDidMount() {
this.focusEditor();
}
render() {
return (
<div style={styles.editor} onClick={this.focusEditor}>
<Editor
ref={this.setEditor}
editorState={this.state.editorState}
onChange={this.onChange}
/>
</div>
);
}
}
const styles = {
editor: {
border: '1px solid gray',
minHeight: '6em'
}
};
ReactDOM.render(
<MyEditor />,
document.getElementById('container')
);
Since the release of React 16.8, you can use Hooks as a way to work with EditorState
without using a class.
import React from 'react';
import ReactDOM from 'react-dom';
import {Editor, EditorState} from 'draft-js';
function MyEditor() {
const [editorState, setEditorState] = React.useState(
EditorState.createEmpty()
);
const editor = React.useRef(null);
function focusEditor() {
editor.current.focus();
}
React.useEffect(() => {
focusEditor()
}, []);
return (
<div onClick={focusEditor}>
<Editor
ref={editor}
editorState={editorState}
onChange={editorState => setEditorState(editorState)}
/>
</div>
);
}
Note that the editor itself is only as tall as its contents. In order to give users a visual cue, we recommend setting a border and a minimum height via the .DraftEditor-root
CSS selector, or using a wrapper div like in the above example.
Because Draft.js supports unicode, you must have the following meta tag in the <head>
</head>
block of your HTML file:
<meta charset="utf-8" />
Further examples of how Draft.js can be used are provided below.
Examples
Visit http://draftjs.org/ to try out a simple rich editor example.
The repository includes a variety of different editor examples to demonstrate
some of the features offered by the framework.
To run the examples, first build Draft.js locally:
git clone https://github.com/facebook/draft-js.git
cd draft-js
npm install
npm run build
then open the example HTML files in your browser.
Draft.js is used in production on Facebook, including status and
comment inputs, Notes, and
messenger.com.
