What is lowlight?

The lowlight npm package is a library for syntax highlighting of code using languages supported by highlight.js. It is primarily used to parse and transform code into a syntax-highlighted format without a browser, making it suitable for server-side applications or pre-processing of static pages.

What are lowlight's main functionalities?

Syntax Highlighting

This feature allows you to highlight syntax of various programming languages. The code sample demonstrates highlighting a simple JavaScript code snippet.

const lowlight = require('lowlight');
const highlightedCode = lowlight.highlight('javascript', 'const x = 123;').value;
console.log(highlightedCode);

Registering Languages

This feature enables the addition of new languages to lowlight's highlighting capabilities by registering them through highlight.js. The code sample shows how to register and highlight Python code.

const lowlight = require('lowlight');
lowlight.registerLanguage('python', require('highlight.js/lib/languages/python'));
const highlightedPython = lowlight.highlight('python', 'def foo(): return 123').value;
console.log(highlightedPython);

Auto-Detection of Language

This feature automatically detects the programming language of a given code snippet and applies appropriate syntax highlighting. The code sample demonstrates auto-detection for a JavaScript snippet.

const lowlight = require('lowlight');
const result = lowlight.highlightAuto('const x = 123;');
console.log(result.language); // 'javascript'
console.log(result.value);
