- 🪶 Lightweight (~2kB for the core + ~1kB by language)
- ⚡ Fast (faster than prism and highlight.js on average)
- 🧹 Minimal Codebase
Simple setup 🚀
Web
Style/theme (in the header of your html file):
<link rel="stylesheet" href="/path/dist/themes/default.css">
In the body of your html file:
<div class='shj-lang-[code-language]'>[code]</div>
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 '../dist/index.js';
import { detectLanguage } from '../dist/detect.js';
elm.textContent = code;
highlightElement(elm, detectLanguage(code));
Load custom language
import { loadLanguage } from '../dist/index.js';
loadLanguage('language-name', customLanguage);
CDN
<link rel="stylesheet" href="https://unpkg.com/@speed-highlight/core/dist/themes/default.css">
<link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/speed-highlight/core/dist/themes/default.css">
import ... from 'https://unpkg.com/@speed-highlight/core/dist/index.js';
import ... from 'https://cdn.jsdelivr.net/gh/speed-highlight/core/dist/index.js';
Deno
Use the deno module
import { setTheme, printHighlight } from 'https://deno.land/x/speed_highlight_js/dist/terminal.js';
await setTheme('[theme-name]');
printHighlight('console.log("hello")', 'js');
Node
Use the npm package
npm i @speed-highlight/core
const { setTheme, printHighlight } = require('@speed-highlight/core/terminal');
setTheme('[theme-name]');
printHighlight('console.log("hello")', 'js');
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
<head>
- <link href="themes/prism.css" rel="stylesheet" />
+ <link rel="stylesheet" href="https://unpkg.com/@speed-highlight/core/dist/themes/default.css">
</head>
Script
For the script part remove the prism.js script and replace it by a import and a call to highlightAll
<body>
- <script src="prism.js"></script>
+<script>
+ import { highlightAll } from 'https://unpkg.com/@speed-highlight/core/dist/index.js';
+ highlightAll();
+</script>
</body>
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>
