mui-rte

The Material-UI Rich Text Editor and Viewer

mui-rte is a complete text editor and viewer for the MUI library (formerly 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, autocomplete strategies, async/sync custom atomic blocks, 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: @mui/material, @mui/icons-material, @mui/styles, react and react-dom. Also you will need to install the peer dependencies for MUI: @emotion/react and @emotion/styled.

Demo

Edit mui-rte basic

Usage

import { createTheme, ThemeProvider } from '@mui/material/styles'
import MUIRichTextEditor from 'mui-rte'

const myTheme = createTheme({
    // Set up your custom MUI theme here
})

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

Material-UI v4 compatibility

mui-rte version 2.x is compatible with MUI (v5) only. You can still use version 1.x for Material-UI v4. Current code using mui-rte version 1.x should be compatible with version 2.x, the only breaking change is that it requires to be wrapped on a ThemeProvider as shown in the examples.

Examples

Custom Controls

You can define your custom inline styles, blocks, atomic blocks and callback actions to the editor. Just select an icon from @mui/icons-material 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 '@mui/icons-material/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 '@mui/icons-material/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 (Async)

It is possible to insert custom blocks based on asynchronous behavior using the insertAtomicBlockAsync API. The above example shows an example on how to upload an image and use the MUIRichTextEditor default image control for further edition. You can use this behavior to upload a file when dropping it inside the editor and render it as an image entity after upload.

Check this other sample that shows how to add a @mui/material Card with asynchronous downloaded content.

Adding a custom atomic block (Sync)

Check this sample that shows how to create a control to add a @mui/material 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 '@mui/icons-material/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()
            }
        }
    ]}
/>

Autocomplete strategies

You can define autocomplete strategies to present suggested content lists based on the text input. Just set your trigger character, add some search keys and the content to insert and the editor will do everything for you. You can navigate through suggestions using the keyboard arrows and finally press 'Enter' to insert your content into the editor.

Simple strategy example

This is an example to show emoji suggestions when the user start typing a text like ':face', ':joy', or ':grin':

import MUIRichTextEditor from 'mui-rte'

const emojis = [
    {
        keys: ["face", "grin"],
        value: "😀",
        content: "😀",
    },
    {
        keys: ["face", "joy"],
        value: "😂",
        content: "😂",
    },
    {
        keys: ["face", "sweat"],
        value: "😅",
        content: "😅",
    }
]

<MUIRichTextEditor 
    autocomplete={{
        strategies: [
            {
                items: emojis,
                triggerChar: ":"
            }
        ]
    }}
/>

Check this sample that shows how to add multiple autocomplete strategies to a single editor.

Atomic strategy example

Check this sample that shows how to combine atomic custom controls with the autocomplete strategy feature.

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 '@mui/material/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>
