Full list of features


Basic usage

You will need to include the prism.css and prism.js files you downloaded in your page. Example:

<!DOCTYPE html>
	<link href="themes/prism.css" rel="stylesheet" />
	<script src="prism.js"></script>

Prism does its best to encourage good authoring practices. Therefore, it only works with <code> elements, since marking up code without a <code> element is semantically invalid. According to the HTML5 spec, the recommended way to define a code language is a language-xxxx class, which is what Prism uses. Alternatively, Prism also supports a shorter version: lang-xxxx.

To make things easier however, Prism assumes that this language definition is inherited. Therefore, if multiple <code> elements have the same language, you can add the language-xxxx class on one of their common ancestors. This way, you can also define a document-wide default language, by adding a language-xxxx class on the <body> or <html> element.

If you want to opt-out of highlighting for a <code> element that is a descendant of an element with a declared code language, you can add the class language-none to it (or any non-existing language, really).

The recommended way to mark up a code block (both for semantics and for Prism) is a <pre> element with a <code> element inside, like so:

<pre><code class="language-css">p { color: red }</code></pre>

If you use that pattern, the <pre> will automatically get the language-xxxx class (if it doesn’t already have it) and will be styled as a code block.

If you want to prevent any elements from being automatically highlighted, you can use the attribute data-manual on the <script> element you used for prism and use the API. Example:

<script src="prism.js" data-manual></script>

Usage with Webpack, Browserify, & Other Bundlers

If you want to use Prism with a bundler, install Prism with npm:

$ npm install prismjs

You can then import into your bundle:

import Prism from 'prismjs';

To make it easy to configure your Prism instance with only the languages and plugins you need, use the babel plugin, babel-plugin-prismjs. This will allow you to load the minimum number of languages and plugins to satisfy your needs. See that plugin's documentation for configuration details.

Usage with Node

If you want to use Prism on the server or through the command line, Prism can be used with Node.js as well. This might be useful if you're trying to generate static HTML pages with highlighted code for environments that don't support browser-side JS, like AMP pages.


var Prism = require('prismjs');

// The code snippet you want to highlight, as a string
var code = "var data = 1;";

// Returns a highlighted HTML string
var html = Prism.highlight(code, Prism.languages.javascript, 'javascript');

Requiring prismjs will load the default languages: markup, css, clike and javascript. You can load more languages with the loadLanguages() utility, which will automatically handle any required dependencies.


var Prism = require('prismjs');
var loadLanguages = require('prismjs/components/');

// The code snippet you want to highlight, as a string
var code = "= ['hi', 'there', 'reader!'].join \" \"";

// Returns a highlighted HTML string
var html = Prism.highlight(code, Prism.languages.haml, 'haml');

Note: Do not use loadLanguages() with Webpack or another bundler, as this will cause Webpack to include all languages and plugins. Use the babel plugin described above.

Supported languages

This is the list of all languages currently supported by Prism, with their corresponding alias, to use in place of xxxx in the language-xxxx (or lang-xxxx) class:

Plugins are additional scripts (and CSS code) that extend Prism’s functionality. Many of the following plugins are official, but are released as plugins to keep the Prism Core small for those who don’t need the extra functionality.

No assembly required to use them. Just select them in the download page.

It’s very easy to write your own Prism plugins. Did you write a plugin for Prism that you want added to this list? Send a pull request!
