A lightweight, and easy-to-use, JavaScript library for code syntax highlighting!

v3.1.0

• Zero-dependencies and extremely lightweight!
• Written in TypeScript, allowing greater support for React, Angular, and other libraries!
• Highlights keywords, values, strings, and comments.
• 51 language translations available!
• Full API available via public functions.
• Fully styled in CSS/SASS (including the buttons) and compatible with the Bootstrap library.
• Full CSS theme support (using :root variables, with a default dark-mode theme).
• Coping and Printing support is available via action buttons.
• Custom triggers for actions (when elements are rendered, keywords are clicked, etc).
• 27 of the most popular languages built in by default (with public function support to add more).
• Language aliases.
• Custom action buttons (via a binding attribute), with opening/closing support.
• Unknown language support (renders the display, but does not highlight any syntax).
• Tabbing (allows multiple languages to be shown in one tabbed container, which is great for code examples).

All the documentation can be found here:

All modern browsers (such as Google Chrome, FireFox, and Opera) are fully supported.
