    Usage

    highlight.js can be used in different ways such using CDNs, hosting the bundle yourself, as a Vue plug-in, as ES6 modules, with Node.js, and web workers.

    See our README on GitHub for more details.

    As a Module

    Highlight.js can be used with Node on the server. The first step is to install the package from npm:

    npm install highlight.js
    # or
    yarn add highlight.jsLanguage:Bash

    Now, it's possible to use the library using either require or import. By default, when you import the main package, all 192 languages will be loaded automatically.

    // Using require
    const hljs = require('highlight.js');
    
    // Using ES6 import syntax
    import hljs from 'highlight.js';Language:JavaScript

    However, importing all our languages will increase the size of your bundle. If you only need a few languages, you can import them individually:

    // Using require
    const hljs = require('highlight.js/lib/core');
    
    // Load any languages you need
    hljs.registerLanguage('javascript', require('highlight.js/lib/languages/javascript'));Language:JavaScript
    // Using ES6 import syntax
    import hljs from 'highlight.js/lib/core';
    import javascript from 'highlight.js/lib/languages/javascript';
    
    // Then register the languages you need
    hljs.registerLanguage('javascript', javascript);Language:JavaScript

    And finally, regardless of how you imported the library, you can highlight code with the highlight or highlightAuto functions:

    const highlightedCode = hljs.highlight(
      '<span>Hello World!</span>',
      { language: 'xml' }
    ).valueLanguage:JavaScript

    For more details, see the "Importing the Library" section of our README.

    As HTML Tags

    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/11.9.0/styles/default.min.css">
    <script src="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/11.9.0/highlight.min.js"></script>
    
    <!-- and it's easy to individually load additional languages -->
    <script src="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/11.9.0/languages/go.min.js"></script>
    
    <script>hljs.highlightAll();</script>Language:HTML, XML

    This will find and highlight code inside <pre><code> tags; it tries to detect the language automatically. If automatic detection does not work for you, you can specify the language in the class attribute:

    <pre><code class="language-html">...</code></pre>Language:HTML, XML
