Server-side GitHub Flavored Markdown rendering for Deno, including GitHub style CSS, syntax highlighting, and HTML sanitization.
import { CSS, render } from "https://deno.land/x/gfm/mod.ts";
const markdown = `
# Hello, world!
| Type | Value |
| ---- | ----- |
| x | 42 |
\`\`\`js
console.log("Hello, world!");
\`\`\`
`;
const rootUrl = "https://example.com";
const body = render(markdown, rootUrl);
const html = `
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
main {
max-width: 800px;
margin: 0 auto;
}
${CSS}
</style>
</head>
<body>
<main data-color-mode="light" data-light-theme="light" data-dark-theme="dark" class="markdown-body">
${body}
</main>
</body>
</html>
`;The GitHub CSS styles (https://primer.style) are used. There are two themes available: light and dark.
There are three data attributes that can be used to control the theme:
data-color-mode:lightordarkorauto.data-light-theme: the name of the light theme (lightordark).data-dark-theme: the name of the dark theme (lightordark).
For example, if you want to use the dark theme only, set the following:
<div data-color-mode="dark" data-dark-theme="dark" class="markdown-body">
... markdown body here ...
</div>If you want to use the light or dark theme depending on the user's browser preference, set the following:
<div data-color-mode="auto" data-light-theme="light" data-dark-theme="dark" class="markdown-body">
... markdown body here ...
</div>Also see the example application in the example/ directory.
By default syntax highlighting for JavaScript, Markdown, and HTML is included. You can include more languages importing them:
