Overview

Draft Extend is a platform to build a full-featured Draft.js editor using modular plugins that can integrate with draft-convert to serialize with HTML. The higher-order function API makes it extremely easy to use any number of plugins for rendering and conversion.

Usage:

import React from 'react';
import ReactDOM from 'react-dom';
import {EditorState} from 'draft-js';
import {Editor, compose} from 'draft-extend';
import {convertFromHTML, convertToHTML} from 'draft-convert';

const plugins = compose(
    FirstPlugin,
    SecondPlugin,
    ThirdPlugin
);

const EditorWithPlugins = plugins(Editor); // Rich text editor component with plugin functionality
const toHTML = plugins(convertFromHTML); // function to convert from HTML including plugin functionality
const fromHTML = plugins(convertToHTML); // function to convert to HTML including plugin functionality

const MyEditor = React.createClass({
    getInitialState() {
        return {
            editorState: EditorState.createWithContent(fromHTML('<div></div>'))
        };
    },

    onChange(editorState) {
        const html = toHTML(editorState.getCurrentContent());
        console.log(html); // don't actually convert to HTML on every change!
        this.setState({editorState});
    },

    render() {
        return (
            <EditorWithPlugins
                editorState={this.state.editorState}
                onChange={this.onChange}
            />
        );
    }
});

ReactDOM.render(
    <MyEditor />,
    document.querySelector('.app')
);

Examples

Examples of how to build plugins of different types are included in the example directory. To run the examples locally:

1. run npm install in the draft-extend directory
2. open any HTML file in the examples directory in your web browser - no local server is necessary

Editor

Editor component on which to extend functionality with plugins created by createPlugin.

Props

The most important two props are:

• editorState - Draft.js EditorState instance to be rendered.
• onChange: function(editorState: EditorState): void - Like with vanilla Draft.js, function called on any editor change passing the EditorState.

Other props are used by plugins composed around Editor. See Building Plugins for more information. These should generally not be used outside of the context of a plugin:

• buttons: Array<Component> Array of React components to add to the controls of the editor.
• overlays: Array<Component> Array of React components to add as overlays to the editor.
• decorators: Array<DraftDecorator> Array of Draft.js decorator objects used to render the EditorState. They are added to the EditorState as a CompositeDecorator within the component and are of shape {strategy, component}.
• styleMap: Object Object map from Draft.js inline style type to style object. Used for the Draft.js Editor's customStyleMap prop.

All other props are passed down to the Draft.js Editor component and to any buttons and overlays added by plugins.

compose

Since the API of plugins is based around composition, a basic compose function is provided to make it easy to apply plugins to the component as well as conversion functions and provides a single source of truth for plugin configuration.

// without compose
const EditorWithPlugins = FirstPlugin(SecondPlugin(ThirdPlugin(Editor)));
const fromHTML = FirstPlugin(SecondPlugin(ThirdPlugin(convertFromHTML)));
const toHTML = FirstPlugin(SecondPlugin(ThirdPlugin(convertToHTML)));

// with compose
const plugins = compose(
    FirstPlugin,
    SecondPlugin,
    ThirdPlugin
);

const EditorWithPlugins = plugins(Editor);
const toHTML = plugins(convertToHTML);
const fromHTML = plugins(convertFromHTML);
