### Configure laravel-github-readme options

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/README.md

Default configuration for the laravel-github-readme package. Set the disk, check interval, token, user agent, timeout, and optional custom renderer. The renderer defaults to null, using the internal League\CommonMark renderer with GFM and heading permalinks.

```php
return [
    // The filesystem disk used to store rendered README HTML files.
    'disk' => env('GITHUB_README_DISK', 'local'),

    // Minutes a freshly verified README is served without contacting GitHub.
    'check_interval_minutes' => (int) env('GITHUB_README_CHECK_INTERVAL', 10),

    // Optional GitHub token (falls back to config('services.github.token')).
    'token' => env('GITHUB_TOKEN', env('GITHUB_README_TOKEN')),

    // User-Agent header sent on every GitHub API request.
    'user_agent' => env('GITHUB_README_USER_AGENT', 'laravel-github-readme'),

    // Request timeout in seconds.
    'timeout' => (int) env('GITHUB_README_TIMEOUT', 8),

    // Optional renderer callable: fn (string $markdown): string.
    // Null uses the internal League\CommonMark renderer (GFM + heading permalinks).
    'renderer' => null,
];
```

--------------------------------

### Run tests, coverage, PHPStan, and Pint

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/resources/boost/skills/github-readme-development/SKILL.md

Commands to run the test suite, generate coverage, run static analysis with PHPStan, and format code with Pint.

```bash
vendor/bin/pest          # run tests
vendor/bin/pest --coverage
vendor/bin/phpstan analyse
vendor/bin/pint
```

--------------------------------

### Publish and Run Migration

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/README.md

Publishes and runs the migration that creates the `github_readme_cache` table.

```bash
php artisan vendor:publish --tag="laravel-github-readme-migrations"
php artisan migrate
```

--------------------------------

### Configuration keys for laravel-github-readme

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/resources/boost/skills/github-readme-development/SKILL.md

Configuration keys for the package. The token falls back to `config('services.github.token')` when the package key is null.

```php
'disk' => env('GITHUB_README_DISK', 'local'),
'check_interval_minutes' => (int) env('GITHUB_README_CHECK_INTERVAL', 10),
'token' => env('GITHUB_TOKEN', env('GITHUB_README_TOKEN')),
'user_agent' => env('GITHUB_README_USER_AGENT', 'laravel-github-readme'),
'timeout' => (int) env('GITHUB_README_TIMEOUT', 8),
'renderer' => null,
```

--------------------------------

### Publish Config File

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/README.md

Optionally publishes the config file.

```bash
php artisan vendor:publish --tag="laravel-github-readme-config"
```

--------------------------------

### Use a dedicated disk for cached READMEs

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/README.md

Define a dedicated 'github' disk in config/filesystems.php and set the GITHUB_README_DISK environment variable to 'github' to isolate cached READMEs from the default local disk.

```php
// config/filesystems.php
'disks' => [
    'github' => [
        'driver' => 'local',
        'root' => storage_path('app/github'),
        'throw' => false,
    ],
],
```

```dotenv
GITHUB_README_DISK=github
```

--------------------------------

### Configure Laravel package with Spatie PackageServiceProvider

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/resources/boost/skills/github-readme-development/SKILL.md

Registers the package with Spatie's PackageServiceProvider. The hasMigration call publishes the migration stub under the 'laravel-github-readme-migrations' tag.

```php
public function configurePackage(Package $package): void
{
    $package
        ->name('laravel-github-readme')
        ->hasConfigFile()
        ->hasMigration('create_github_readme_cache_table');
}
```

--------------------------------

### Fetch and Sanitize README HTML

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/README.md

Fetches a repository README as HTML, optionally for a specific branch/tag/ref, and sanitizes it before display. The HTML is untrusted and must always be sanitized.

```php
use JeffersonGoncalves\GitHubReadme\GitHubReadme;
use JeffersonGoncalves\HtmlSanitizer\Facades\HtmlSanitizer; // example sanitizer

// Fetch the default-branch README, rendered to HTML and cached on disk.
$html = GitHubReadme::fetchHtml('https://github.com/owner/repo');

// Fetch a specific branch/tag/ref.
$html = GitHubReadme::fetchHtml('https://github.com/owner/repo', '2.x');

// ALWAYS sanitize before display — the HTML is untrusted.
echo HtmlSanitizer::clean($html);
```

--------------------------------

### Run tests with composer test

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/README.md

Runs the test suite for the package using Composer.

```bash
composer test
```

--------------------------------

### Post-process HTML with Helpers

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/README.md

Post-processing helpers to decorate the rendered HTML: mark external links, lazy-load images, and wrap wide tables. All are pure and safe to chain.

```php
// Open off-site links in a new tab with rel="nofollow noopener".
$html = GitHubReadme::markExternalLinks($html, 'mysite.test');

// Lazy-load every image except the first (kept eager as the LCP candidate).
$html = GitHubReadme::lazyloadImages($html);

// Wrap wide tables in a horizontally-scrollable container.
$html = GitHubReadme::wrapTables($html);
```

--------------------------------

### Pest tests for GitHubReadme fetch and cache behavior

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/resources/boost/skills/github-readme-development/SKILL.md

Pest tests for the GitHubReadme package. The first test verifies that a fresh fetch renders the README and stores a cache entry. The second test travels 11 minutes past the freshness window to force a conditional request and asserts the cached HTML is reused on a 304 response.

```php
use Illuminate\Support\Facades\Http;
use Illuminate\Support\Facades\Storage;
use JeffersonGoncalves\GitHubReadme\GitHubReadme;
use JeffersonGoncalves\GitHubReadme\Models\ReadmeCache;

it('renders and stores on first fetch', function () {
    Storage::fake('local');
    Http::fake([
        'api.github.com/repos/owner/repo/readme*' => Http::response('# Hi', 200, ['ETag' => '"e1"']),
    ]);

    $html = GitHubReadme::fetchHtml('https://github.com/owner/repo', 'main');

    expect($html)->toContain('Hi');
    expect(ReadmeCache::where('repo', 'owner/repo')->exists())->toBeTrue();
    Http::assertSentCount(1);
});

it('reuses the cache on a 304', function () {
    Storage::fake('local');
    Http::fakeSequence('api.github.com/*')
        ->push('# Hi', 200, ['ETag' => '"e1"'])
        ->push('', 304);

    $first = GitHubReadme::fetchHtml('https://github.com/owner/repo', 'main');
    $this->travel(11)->minutes();
    $second = GitHubReadme::fetchHtml('https://github.com/owner/repo', 'main');

    expect($second)->toBe($first);
    Http::assertSentCount(2);
});
```

--------------------------------

### Custom markdown renderer with heading permalinks

Source: https://github.com/jeffersongoncalves/laravel-github-readme/blob/master/README.md

Set a custom markdown renderer callable. The built-in renderer strips raw HTML; if your custom renderer allows raw HTML, you must sanitize the output before it reaches a browser.

```php
'renderer' => fn (string $markdown): string => \JeffersonGoncalves\Markdown\Markdown::render($markdown, headingPermalinks: true),
```
