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.

README

Draft.js

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.

Examples

Visit https://facebook.github.io/draft-js/ 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.
