mui-rte

The Material-UI Rich Text Editor and Viewer

mui-rte is a complete text editor and viewer for material-ui based on draft-js and written in Typescript. It is ready to use out of the box yet supports user defined blocks, styles, callbacks, and decorators as well as toolbar and theme customization to enhance the editor to all needs.

Installation

npm install mui-rte --save

Install the peer dependencies: @material-ui/core, @material-ui/icons, react and react-dom.

Demo

Usage

import MUIRichTextEditor from 'mui-rte'

ReactDOM.render(
    <MUIRichTextEditor label="Start typing..." />, 
    document.getElementById("root")
)

You can load default content as the following example. The value should be a stringified RawDraftContentState object:

import MUIRichTextEditor from 'mui-rte'

const data = getContentStateAsStringFromSomewhere()

ReactDOM.render(
    <MUIRichTextEditor 
        value={data}
        label="Start typing..." 
    />, 
    document.getElementById("root")
)

Examples

Custom Controls

You can define your custom inline styles, blocks, atomic blocks and callback actions to the editor. Just select an icon from @material-ui/icons or create your own FunctionComponent and define your rules.

Adding a custom inline style

This sample adds a control to change the background color and font color of the typed or selected text:

import MUIRichTextEditor from 'mui-rte'
import InvertColorsIcon from '@material-ui/icons/InvertColors'

<MUIRichTextEditor 
    controls={["my-style"]}
    customControls={[
        {
            name: "my-style",
            icon: <InvertColorsIcon />,
            type: "inline",
            inlineStyle: {
                backgroundColor: "black",
                color: "white"
            }
        }
    ]}
/>

Adding a custom block

This sample adds a block to the editor based on a React Element:

import MUIRichTextEditor from 'mui-rte'
import TableChartIcon from '@material-ui/icons/TableChart'

const MyBlock = (props) => {
    return (
        <div style={{
            padding: 10,
            backgroundColor: "#ebebeb"
        }}>
            My Block content is:
            {props.children}
        </div>
    )
}

<MUIRichTextEditor 
    controls={["my-block"]}
    customControls={[
        {
            name: "my-block",
            icon: <TableChartIcon />,
            type: "block",
            blockWrapper: <MyBlock />
        }
    ]}
/>

Adding a custom atomic block

Check this sample that shows how to create a control to add a @material-ui/core Card component to the editor.

Adding a custom callback control

This sample adds a control that will trigger a custom callback function to clear the editor state:

import MUIRichTextEditor from 'mui-rte'
import DoneIcon from '@material-ui/icons/Done'
import { EditorState } from 'draft-js'

<MUIRichTextEditor 
    controls={["my-callback"]}
    customControls={[
        {
            name: "my-callback",
            icon: <DoneIcon />,
            type: "callback",
            onClick: (editorState, name, anchor) => {
                console.log(`Clicked ${name} control`)
                return EditorState.createEmpty()
            }
        }
    ]}
/>

Custom Decorators

You can define custom decorators to apply styles and/or functionality based on a provided regular expression.

Adding custom functionality with a decorator

To add some functionality when a user inputs a #hashtag use the following example. In this case, everytime the user inputs a word starting with a # character it will be automatically converted into a styled link:

import MUIRichTextEditor from 'mui-rte'

const MyHashTagDecorator = (props) => {
    const hashtagUrl = "http://myurl/" + props.decoratedText
    return (
        <a 
            href={hashtagUrl}
            style={{
                color: "green"
            }}
        >
            {props.children}
        </a>
    )
}

<MUIRichTextEditor 
    label="Type something here..."
    decorators={[
        {
            component: MyHashTagDecorator,
            regex: /\#[\w]+/g
        }
    ]}
/>

Inline toolbar

The editor includes an inline toolbar option which renders a pop-up inside the editor area when the user makes a selection. The inline toolbar supports user defined controls. Notice that only inline type controls will be rendered. The controls displayed on the main toolbar can be different from the ones in the inline toolbar. You can also hide the main toolbar and just enable the inline toolbar.

import MUIRichTextEditor from 'mui-rte'

<MUIRichTextEditor 
    label="Type something here..."
    inlineToolbar={true}
/>

Styling the editor

You can style the editor using the Material-UI theming feature. First create a theme with createMuiTheme and override classes such as root, container, editor, and editorContainer. Check the examples directory for more.

import { createMuiTheme, MuiThemeProvider } from '@material-ui/core/styles'
import MUIRichTextEditor from 'mui-rte'

const defaultTheme = createMuiTheme()

Object.assign(defaultTheme, {
    overrides: {
        MUIRichTextEditor: {
            root: {
                marginTop: 20,
                width: "80%"
            },
            editor: {
                borderBottom: "1px solid gray" 
            }
        }
    }
})

<MuiThemeProvider theme={defaultTheme}>
    <MUIRichTextEditor 
        label="Type something here..."
    />
</MuiThemeProvider>
