Enlightening Syntax Highlighting in Docusaurus

Docusaurus is a dynamic platform that works wonders for improving your project webpages and documentation. It's more than simply a static site generator.

Syntax Highlighting: Shedding Light on the Code

The technique of highlighting particular words and characters in source code to make it easier to read and comprehend is known as syntax highlighting.

The Anatomy of Syntax Highlighting

  1. Including Prism.js
    The renowned Prism.js package is used by Docusaurus to highlight syntax. The open-source syntax highlighter Prism.js is renowned for its versatility and wide language support.

  2. Plugin Docusaurus
    Very an exclusive plugin, Docusaurus integrates Prism.js with ease. Prism.js must be configured by the plugin in order for it to function with your documentation.

  3. Component of a Code Block
    Docusaurus makes use of a unique code block component to implement syntax highlighting. Code samples in your Markdown files are processed by this component, which then applies the proper syntax highlighting depending on the code language.

  4. Code Blocks in Markdown

function greet() {
  console.log("Hello, world!");
}
Enter fullscreen mode Exit fullscreen mode

Peeking into the Code
Let's now investigate how Docusaurus handles syntax highlighting inside the source. Here are a few salient points:

  • The Docusaurus configuration file, usually called `docusaurus.config.js}, contains the configuration for the Prism.js plugin.
  • Docusaurus interfaces with Prism.js by developing a unique code block component. This part is contained in the source code of Docusaurus.
  • To provide syntax highlighting, the code block component searches your code blocks for language tags and applies the appropriate Prism.js style.
  • To fit the aesthetics of your project, you may even add your own code themes and modify the Prism.js styles.
