draft-js-regex-highlighter-plugin

A DraftJS plugin for highlighting valid/invalid strings based on regex and/or supplied strings.

This plugin has only been tested with [react-draft-wysiwyg] but should work using any DraftJS-based editor.

View Demo

Usage

npm i --save draft-js-regex-highlighter-plugin

then import from your editor component

import { createHighlighterPlugin } from "draft-js-regex-highlighter-plugin"

Example

This example uses a regex to match all {{ handlebar }} variables.

import React, { Component } from "react"
import { Editor } from "react-draft-wysiwyg"
import { createHighlighterPlugin } from "draft-js-regex-highlighter-plugin"
import { EditorState } from "draft-js"

const highlighterConfig = {
      regex: new RegExp(/{{\s*([^}]+)\s*}}/, 'g'),
      theme: {
        valid: {
            background: "lightblue"
        }
        invalid: {
            background: "red"
        }
      }
    }

const customDecorators = [
    createHighlighterPlugin(highlighterConfig)
]

export default class DemoEditor extends Component {

    state = {
        editorState: EditorState.createEmpty()
    }

    onChange = (editorState) => {
        this.setState({ editorState })
    }

    render() {
        return (
            <Editor
                editorState={this.state.editorState}
                onEditorStateChange={this.onChange}
                customDecorators={customDecorators}
            />
        )
    }
}
