Rich text editor is a React component based on Slate with the Material UIlook and feel.

Status: alfa. Pending:

• Improve documentation
• Improve performance
• Create unit tests

Install

npm install --save @unicef/material-slate

Include the editor in your component

import React from "react"
import { useState, useMemo } from "react"
import {
  MaterialSlate,
  MaterialEditable,
  createMaterialEditor,
  Toolbar
} from '@unicef/material-slate' 

export default function MyComponent() {
  // Holds the value of the editor
  const [value, setValue] = useState({})

  // An instance of material editor. It is an slate editor with a few more functions
  const editor = useMemo(() => createMaterialEditor(), [])

  return (
    <MaterialSlate editor={editor} value={value} onChange={(value) => setValue(value)}>
      <Toolbar />
      <MaterialEditable />
    </MaterialSlate>
  )
}

Because this editor is just a wrapper of Slate, it can be fully extended following the Slate docs.

More examples

Two types of button bars can be added:

• <Toolbar />. Regular button bar that appears at the top
• <HoveringToolbar />). A toolbar that appears over a selected text. It is displayed only when a text is selected.

Toolbars shall be included within <MaterialSlate /> component.

By default both toolbars display a predefined set of buttons. To customize the buttons that appear in your toolbar, add the buttons you want as children.

For example if you want to display only bold and italic buttons:

//...
import { BoldButton, ItalicButton } from '@unicef/material-slate'
//...

//...
<HoveringToolbar >
  <BoldButton />
  <ItalicButton />
</HoveringToolbar>

The complete list of available buttons is in /src/component/Buttons folder.

In order to create your custom behavior you can add a ToolbarButton in a toolbar.

The steps

1. Add the customized ToolbarButton to the toolbar
2. Extend renderElement
