Laravel Markdown

A shared CommonMark renderer for Laravel with GitHub Flavored Markdown, optional heading permalinks, and server-side syntax highlighting on fenced code blocks. Highlighting is class-based (<span class="hl-…"> tokens via tempest/highlight's CssTheme) so the markup survives HTML sanitisation — you style the .hl-* classes in your own CSS.

Installation

You can install the package via composer:

composer require jeffersongoncalves/laravel-markdown

You can publish the config file with:

php artisan vendor:publish --tag="markdown-config"

This is the contents of the published config file:

return [
    'html_input' => 'allow',
    'allow_unsafe_links' => false,
    'heading_permalink' => [
        'symbol' => '#',
        'html_class' => 'md-anchor',
    ],
];

Usage

use JeffersonGoncalves\Markdown\Markdown;

// Render GitHub Flavored Markdown to HTML
$html = Markdown::render('# Hello **world**');

// Enable heading permalink anchors (adds <a class="md-anchor"> to each heading)
$html = Markdown::render($readme, headingPermalinks: true);

Fenced code blocks are highlighted server-side and emit class-based tokens:

$html = Markdown::render(<<<'MD'
```php
echo 'hello';
```
MD);
// => <pre><code>…<span class="hl-keyword">echo</span>…</code></pre>

Add the matching .hl-* styles (and .md-anchor if you use heading permalinks) to your own CSS.

Warning

The renderer runs with html_input set to allow, so the output is UNSAFE for untrusted input (third-party READMEs, imported article bodies): raw HTML in the source is preserved. Always pass the output through an HTML sanitizer such as jeffersongoncalves/laravel-html-sanitizer before displaying it. Class-based highlight tokens are designed to survive sanitisation; inline-style highlighting would not.
