Features
- Focus on keyboard shortcuts and auto transform of text blocks.
- Image addition with support for rich text captioning.
- Minimize mouse usage.
- Autolists.
- Proper handling of
RETURN
presses. - It also has implementations of some custom blocks like:
caption
- Can be used as a caption for media blocks like image or video instead of nesteddraft-js
instances for simplicity.block-quote-caption

- * - Toggle Unordered list item
- # - Toggle Header-three.
- < - Toggle Caption block.
- > - Toggle unstyled or paragraph block.
- H - Highlight selection.
Other Shortcuts
- CMD/CTRL + K -> Add Link
- CMD/CTRL + SHIFT + K -> Remove link if cursor is inside a word with link.
Editor level commands
These commands are not a part of the core editor but have been implemented in the example code that uses the medium-draft
editor.
- Command/CTRL + S - Save current data to
localstorage
. - Alt + Shift + L - Load previously saved data from
localstorage
.
Special characters while typing: While typing in an empty block, if the content matches one of the following, that particular block's type and look will be changed to the corresponding block specified below
--
- If current block isblockquote
, it will be changed toblock-quote-caption
, elsecaption

Usage
medium-draft
sits on top of draft-js
with some built in functionalities and blocks. Its API is almost the same as that of draft-js
. You can take a look at the demo editor's code to see the implementation.
CSS
Include the css that comes with the library in your HTML -
<link rel="stylesheet" type="text/css" href="https://unpkg.com/medium-draft/dist/medium-draft.css">
If you are using webpack
for bundling, you can import the CSS like this in your JS code
import 'medium-draft/lib/index.css';
If you are using sideButtons
, you will also need to include the css for font-awesome
-
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/font-awesome/4.6.1/css/font-awesome.min.css">
or something equivalent.
JS (ES6)
At the minimum, you need to provide editorState
and onChange
props, the same as draft-js
.
import React from 'react';
import ReactDOM from 'react-dom';
// if using webpack
// import 'medium-draft/lib/index.css';
import {
Editor,
createEditorState,
} from 'medium-draft';
class App extends React.Component {
constructor(props) {
super(props);
this.state = {
editorState: createEditorState(), // for empty content
};
/*
this.state = {
editorState: createEditorState(data), // with content
};
*/
this.onChange = (editorState) => {
this.setState({ editorState });
};
this.refsEditor = React.createRef();
}
componentDidMount() {
this.refsEditor.current.focus();
}
render() {
const { editorState } = this.state;
return (
<Editor
ref={this.refsEditor}
editorState={editorState}
onChange={this.onChange} />
);
}
};
ReactDOM.render(
<App />,
document.getElementById('app')
);
Customizing side buttons
medium-draft
's Editor
accepts a prop called sideButtons
. By default, there is only one (image) button, but you can add more. The sideButtons
prop must be an array of objects with each object having the following signature:
{
"title": "unique-button-name",
"component": ButtonComponent
}
For ex:
{
"title": "Image",
"component": ImageSideButton
}
Example code:
Right now, the image button simply adds an image inside the editor using URL.createObjectURL
. But if you would like to first upload the image to your server and then add that image to the editor, you can follow one of the 2 methods:
-
Either extend the default
ImageSideButton
component that comes withmedium-draft
. -
Or create your own component with the complete functionality yourself.
For simplicity, we will follow the first method. If you study the implementation of ImageSideButton
, you will see an onChange
method that receives the file chooser event where the seleced files are available as event.target.files
. We will simply override this method as we don't want to customize anything else. Also note that each side button component receives getEditorState
function (returns the draft editorState
), setEditorState(newEditorState)
function (sets the new editorState) and close
function which you need to call manually to close the side buttons list:
import React from 'react';
import {
ImageSideButton,
Block,
addNewBlock,
createEditorState,
Editor,
} from 'medium-draft';
import 'isomorphic-fetch';
class CustomImageSideButton extends ImageSideButton {
/*
We will only check for first file and also whether
it is an image or not.
*/
onChange(e) {
const file = e.target.files[0];
if (file.type.indexOf('image/') === 0) {
// This is a post request to server endpoint with image as `image`
const formData = new FormData();
formData.append('image', file);
fetch('/your-server-endpoint', {
method: 'POST',
body: formData,
}).then((response) => {
if (response.status === 200) {
// Assuming server responds with
// `{ "url": "http://example-cdn.com/image.jpg"}`
return response.json().then(data => {
if (data.url) {
this.props.setEditorState(addNewBlock(
this.props.getEditorState(),
Block.IMAGE, {
src: data.url,
}
));
}
});
}
});
}
this.props.close();
}
}
// Now pass this component instead of default prop to Editor example above.
class App extends React.Component {
constructor(props) {
super(props);
this.sideButtons = [{
title: 'Image',
component: CustomImageSideButton,
}];
this.state = {
editorState: createEditorState(), // for empty content
};
/*
this.state = {
editorState: createEditorState(data), // with content
};
*/
this.onChange = (editorState) => {
this.setState({ editorState });
};
this.refsEditor = React.createRefs()
}
componentDidMount() {
this.refsEditor.current.focus();
}
render() {
const { editorState } = this.state;
return (
<Editor
ref={this.refsEditor}
editorState={editorState}
onChange={this.onChange}
sideButtons={this.sideButtons}
/>
);
}
};
Render data to HTML
The feature to export HTML is available from version 0.4.1
onwards.
medium-draft
uses draft-convert (which in turn uses react-dom-server) to render draft-js
's editorState
to HTML.
The exporter is not a part of the core library. If you want to use medium-draft-exporter
, follow these steps -
Browserify/webpack
npm install draft-convert
.
draft-convert
is part of peerDependencies
of medium-draft
.
Code
import mediumDraftExporter from 'medium-draft/lib/exporter';
const editorState = /* your draft editorState */;
const renderedHTML = mediumDraftExporter(editorState.getCurrentContent());
/* Use renderedHTML */
Browser
- Add the following scripts before your js code.
<script src="https://unpkg.com/[email protected]/dist/react-dom-server.min.js"></script>
<script src="https://unpkg.com/[email protected]/dist/draft-convert.min.js"></script>
<script src="https://unpkg.com/medium-draft/dist/medium-draft-exporter.js"></script>
The exporter is available as MediumDraftExporter
global;
- JS
var mediumDraftExporter = MediumDraftExporter.default;
const editorState = /* your draft editorState */;
const renderedHTML = mediumDraftExporter(editorState.getCurrentContent());
/* Use renderedHTML */
The medium-draft-exporter
also comes with a preset CSS if you want to apply some basic styles to the rendered HTML.
-
In webpack, as part of your rendered HTML's page, use this-
import 'medium-draft/lib/basic.css'
-
In browser, in your rendered html's page, you can include this stylesheet link
<link rel="stylesheet" type="text/css" href="https://unpkg.com/medium-draft/dist/basic.css">
medium-draft-exporter
to editorState
Load HTML exported using The feature to export HTML is available from version 0.5.3
onwards.

is part of peerDependencies
of medium-draft
.
Code
import { convertToRaw } from 'draft-js';
import { createEditorState } from 'medium-draft';
import mediumDraftImporter from 'medium-draft/lib/importer';
const html = /* your previously exported html */;
const editorState = createEditorState(convertToRaw(mediumDraftImporter(html)));
// Use this editorState
Browser
- Add the following scripts before your js code.
<script src="https://unpkg.com/[email protected]/dist/react-dom-server.min.js"></script>
<script src="https://unpkg.com/[email protected]/dist/draft-convert.min.js"></script>
<script src="https://unpkg.com/medium-draft/dist/medium-draft-importer.js"></script>
The importer is available as MediumDraftImporter
global;
- JS
const { convertToRaw } = Draft;
const { createEditorState } = MediumDraft;
const mediumDraftImporter = MediumDraftImporter.default;
const html = /* your previously exported html */;
const editorState = createEditorState(convertToRaw(mediumDraftImporter(html)));
// Use this editorState
Issues
- Write an exporter to export draft data to HTML specifically for
medium-draft
. - Figure out a way to show placeholder text for empty image captions.
- Currently, the toolbar that appears when text is selected needs to be fixed regarding its position in the viewport.
