or
<code class="shj-lang-[code-language]">[inline code]</code>

Highlight the code (in your javascript):

import { highlightAll } from '/path/dist/index.js'
highlightAll();

Auto language detection

import { highlightElement } from '../src/index.js';
import { detectLanguage } from '../src/detect.js';

elm.textContent = code;
highlightElement(elm, detectLanguage(code));

import { loadLanguage } from '../src/index.js';

loadLanguage('language-name', customLanguage);

Migrating from prism

Speed-highlight JS is a lighter and faster version of prism that share a similar API

Style

Remove the prism stylesheet in the head of your html file Clone this repository or use a cdn to load our stylesheet

-	
+	

Script

For the script part remove the prism.js script and replace it by a import and a call to highlightAll

-	
+

If you want to highlight only a specific element you can use the highlightElement function instead

Code block

For the code blocks replace the <pre><code> by only one <div> And use shj-lang- prefix instead of language- for the class property

-<pre><code class="language-css">p { color: red }</code></pre>
+<div class="shj-lang-css">p { color: red }</div>

And for inline code block you just have to change the class property

-<code class="language-css">p { color: red }</code>
+<code class="shj-lang-css">p { color: red }</code>
