The bare minimum for using highlight.js on a web page is linking to the library along with one of the styles and calling initHighlightingOnLoad:
This will find and highlight code inside of
tags; it tries to detect the language automatically. If automatic detection doesn’t work for you, you can specify the language in the class attribute: The list of supported language classes is available in the class reference. Classes can also be prefixed with either language- or lang-.
To make arbitrary text look like code, but without highlighting, use the plaintext class:
To disable highlighting altogether use the nohighlight class:
When you need a bit more control over the initialization of highlight.js, you can use the highlightBlock and configure functions. This allows you to control what to highlight and when.
Here’s an equivalent way to calling initHighlightingOnLoad using vanilla JS:
const result = self.hljs.highlightAuto(event.data);
Getting the Library
You can get highlight.js as a hosted, or custom-build, browser script or as a server module. Right out of the box the browser script supports both AMD and CommonJS, so if you wish you can use RequireJS or Browserify without having to build from source. The server module also works perfectly fine with Browserify, but there is the option to use a build specific to browsers rather than something meant for a server. Head over to the download page for all the options.
Don't link to GitHub directly. The library is not supposed to work straight from the source, it requires building. If none of the pre-packaged options work for you refer to the building documentation.
The CDN-hosted package doesn't have all the languages. Otherwise it'd be too big. If you don't see the language you need in the "Common" section, it can be added manually:
On Almond. You need to use the optimizer to give the module a name. For example:
