code-colors-react v1.2.0

code-colors-react

React component for code syntax highlighting.

Why another code syntax highlighting package?

• This package is simple to use. It is very lightweight, it essentially just ships a single React component.
• The highlight.js dependency is loaded from CDN asynchronously.
• highlight.js is run in a Web Worker, so it doesn't block the main thread.
• No layout shifts before the code is highlighted. While the code is being highlighted in the Web Worker, the component renders plain text with the correct dimensions.

Installation

npm i code-colors-react

Usage

import {ColorTokens} from 'code-colors-react';

<pre>
  <ColorTokens code={"console.log('hello world');"} lang={'js'} />
</pre>

Props

• code — The code to highlight.
• lang — The language of the code. If omitted, it will try to autodetect the language.
• prefix — The prefix to use for the CSS classes. Defaults to hljs-.
• as — The root element to render. Defaults to "code".

Styling

To style the highlighted code, you can use any of the pre-defined themes from highlight.js.

You can do it in JavaScript like so:

import {loadCss} from 'thingies/lib/loadCss';

const theme = 'github';
const href = `https://cdn.jsdelivr.net/gh/highlightjs/cdn-release@11.8.0/build/styles/${theme}.min.css`;

loadCss(href, 'hljs');
