📦 Usage npm

Ref. Getting Started

Install

$ npm install @toast-ui/editor-plugin-code-syntax-highlight

Import Plugin

Along with the plugin, the plugin's dependency style must be imported. The code-syntax-highlight plugin has prismjs as a dependency, and you need to add a CSS file of prismjs.

ES Modules

import 'prismjs/themes/prism.css';
import '@toast-ui/editor-plugin-code-syntax-highlight/dist/toastui-editor-plugin-code-syntax-highlight.css';

import codeSyntaxHighlight from '@toast-ui/editor-plugin-code-syntax-highlight';

CommonJS

require('prismjs/themes/prism.css');
require('@toast-ui/editor-plugin-code-syntax-highlight/dist/toastui-editor-plugin-code-syntax-highlight.css');

const codeSyntaxHighlight = require('@toast-ui/editor-plugin-code-syntax-highlight');

Create Instance

When you set up a plugin function, you must set it with an option. The option has highlighter, and you need to import prismjs before creating an instance and set it to the value of that option.

The main bundle file of prismjs contains just several language pack it supports. So we provides the bundle file(toastui-editor-plugin-code-syntax-highlight-all.js) to import all languages you need in prismjs.

Basic

Import All Languages

// ...
import 'prismjs/themes/prism.css';
import '@toast-ui/editor-plugin-code-syntax-highlight/dist/toastui-editor-plugin-code-syntax-highlight.css';

import Editor from '@toast-ui/editor';
import codeSyntaxHighlight from '@toast-ui/editor-plugin-code-syntax-highlight/dist/toastui-editor-plugin-code-syntax-highlight-all.js';


const editor = new Editor({
  // ...
  plugins: [codeSyntaxHighlight]
});

Import Only Languages ​​You Need

You need to import the language files you want to use in the code block and register them in the prismjs object. A list of available language files can be found here.

// ...
import 'prismjs/themes/prism.css';
import '@toast-ui/editor-plugin-code-syntax-highlight/dist/toastui-editor-plugin-code-syntax-highlight.css';

// Step 1. Import prismjs
import Prism from 'prismjs';

// Step 2. Import language files of prismjs that you need
import 'prismjs/components/prism-clojure.js';

import Editor from '@toast-ui/editor';
import codeSyntaxHighlight from '@toast-ui/editor-plugin-code-syntax-highlight';

const editor = new Editor({
  // ...
  plugins: [[codeSyntaxHighlight, { highlighter: Prism }]]
});

With Viewer

As with creating an editor instance, you need to import prismjs and pass it to the highlighter option.

// ...
import 'prismjs/themes/prism.css';
import '@toast-ui/editor-plugin-code-syntax-highlight/dist/toastui-editor-plugin-code-syntax-highlight.css';

// Import prismjs
import Prism from 'prismjs';

import Viewer from '@toast-ui/editor/dist/toastui-editor-viewer';
import codeSyntaxHighlight from '@toast-ui/editor-plugin-code-syntax-highlight';


const viewer = new Viewer({
  // ...
  plugins: [[codeSyntaxHighlight, { highlighter: Prism }]]
});

or

// ...
import 'prismjs/themes/prism.css';
import '@toast-ui/editor-plugin-code-syntax-highlight/dist/toastui-editor-plugin-code-syntax-highlight.css';

// Import prismjs
import Prism from 'prismjs';

import Editor from '@toast-ui/editor';
import codeSyntaxHighlight from '@toast-ui/editor-plugin-code-syntax-highlight';

const viewer = Editor.factory({
  // ...
  viewer: true,
  plugins: [[codeSyntaxHighlight, { highlighter: Prism }]]
});
