Requirements

Before installing Filament Docs, ensure your system meets the following requirements:

System Requirements

PHP: 8.1 or higher (8.2+ recommended for optimal performance)
Laravel: 10.0 or higher
Filament: 3.0 or higher

PHP Extensions

The following PHP extensions are required:

mbstring - For proper text encoding handling
json - For configuration and data processing
fileinfo - For file type detection
dom - For HTML parsing and manipulation

Optional Dependencies

For enhanced functionality, consider installing:

league/commonmark - Enhanced markdown processing (auto-installed)
spatie/laravel-markdown - Additional markdown features
intervention/image - Image processing for documentation assets

Browser Compatibility

Modern Browsers: Chrome 90+, Firefox 88+, Safari 14+, Edge 90+
Mobile: iOS Safari 14+, Chrome Mobile 90+
Legacy Support: Internet Explorer is not supported

Installation

Step 1: Install via Composer

Install the package using Composer. This will automatically handle all dependencies:

composer require eightynine/filament-docs

Step 2: Publish Configuration Files

Publish the configuration file to customize the package behavior:

php artisan vendor:publish --tag="filament-docs-config"

This creates config/filament-docs.php where you can configure:

Default documentation paths
Markdown processing options
Search behavior settings
UI customization options

Step 3: Publish Views (Optional)

If you need to customize the views, publish them:

php artisan vendor:publish --tag="filament-docs-views"

This publishes views to resources/views/vendor/filament-docs/ for customization.

Step 4: Publish Translations (Optional)

For internationalization support, publish the language files:

php artisan vendor:publish --tag="filament-docs-translations"

This creates language files in resources/lang/vendor/filament-docs/.

Step 5: Publish Assets (Optional)

To customize CSS and JavaScript:

php artisan vendor:publish --tag="filament-docs-assets"

Step 6: Create Documentation Directory

Create your documentation directory structure:

mkdir -p resources/docs

Automatic Registration

The package uses auto-discovery, so the service provider will be automatically registered. If you've disabled auto-discovery, manually add the service provider to config/app.php:

'providers' => [
    // Other service providers...
    EightyNine\FilamentDocs\FilamentDocsServiceProvider::class,
],

Configuration

After publishing the configuration file, you'll find config/filament-docs.php with comprehensive options to customize the package behavior.

Usage

Filament Docs provides multiple ways to create and manage documentation within your Filament application. This section covers everything from basic setup to advanced customization.

Quick Start Guide

1. Create Your First Documentation Page

The fastest way to get started is using the Artisan command:

php artisan make:filament-docs-page UserManual \
    --navigation-group="Help & Documentation" \
    --navigation-icon="heroicon-o-book-open" \
    --navigation-sort=10

This single command creates:

Page Class: app/Filament/Pages/UserManual.php - The Filament page
View File: resources/views/filament/pages/user-manual.blade.php - Custom view (if needed)
Documentation Directory: resources/user-manual/ - Where your markdown files go
Sample Content: Example markdown files to get you started

2. Add Your Documentation Content

Navigate to your newly created documentation directory and start adding markdown files:

# Navigate to your docs directory
cd resources/user-manual

# Create your first documentation file
echo "# Welcome to the User Manual" > getting-started.md

3. Access Your Documentation

Your documentation page is now available in your Filament admin panel under the navigation group you specified!

Markdown Best Practices

Create effective documentation with these markdown conventions:

# Page Title (H1 - Use only once per file)

Brief description of what this page covers.

## Main Section (H2)

Content for the main section.

### Subsection (H3)

More detailed content.

#### Details (H4)

Fine-grained details.

## Code Examples

Use fenced code blocks with language specification:

```php
<?php

class Example 
{
    public function method(): string 
    {
        return 'Hello World';
    }
}

Important Information

Note: Use blockquotes for important notes.

Warning: Use blockquotes for warnings.

Tip: Use blockquotes for helpful tips.

### Multi-Language Documentation

#### Setting Up Multi-Language Support

Configure your application for multiple languages:

```php
// config/filament-docs.php
return [
    'localization' => [
        'supported_locales' => ['en', 'es', 'fr', 'de'],
        'locale_paths' => [
            'en' => 'docs/en',
            'es' => 'docs/es', 
            'fr' => 'docs/fr',
            'de' => 'docs/de',
        ],
        'fallback_to_default' => true,
    ],
];

Directory Structure for Multi-Language

resources/docs/

Language-Aware Documentation Page

class MultiLanguageDocs extends DocsPage
{
    protected function getDocsPath(): string
    {
        $locale = app()->getLocale();
        $paths = config('filament-docs.localization.locale_paths');
        
        return resource_path($paths[$locale] ?? $paths['en']);
    }

    public function getTitle(): string
    {
        return __('filament-docs::docs.title');
    }

    protected function getSectionTitle(string $filename): string
    {
        // Try to get translated title first
        $translationKey = "docs.sections.{$filename}";
        $translated = __($translationKey);
        
        if ($translated !== $translationKey) {
            return $translated;
        }
        
        // Fallback to formatted filename
        return parent::getSectionTitle($filename);
    }
}

Customization & Theming

Filament Docs provides extensive customization options to match your application's design and functionality requirements.

Visual Customization

Custom Styling with CSS

Publish and customize the CSS assets:

php artisan vendor:publish --tag="filament-docs-assets"

This creates customizable CSS files in resources/css/vendor/filament-docs/:

/* resources/css/vendor/filament-docs/custom.css */

/* Custom documentation container */
.docs-container {
    @apply max-w-7xl mx-auto px-4 sm:px-6 lg:px-8;
}

Theme Integration

Custom Filament Theme Integration

Integrate seamlessly with custom Filament themes:

// In your AppServiceProvider or custom service provider
public function boot(): void
{
    // Register custom theme for documentation
    Filament::serving(function () {
        Filament::registerTheme(
            app(AssetManager::class)->getThemeStylesheets()[0] ?? 
            asset('css/filament/docs/theme.css')
        );
    });
}

Create a custom theme CSS file:

/* resources/css/filament/docs/theme.css */

/* Inherit from main Filament theme */
@import '../app/theme.css';

/* Documentation-specific overrides */
.fi-docs-page {
    --docs-primary-color: theme('colors.blue.600');
    --docs-secondary-color: theme('colors.gray.600');
    --docs-accent-color: theme('colors.amber.500');
}

/* Dark theme support */
.dark .fi-docs-page {
    --docs-primary-color: theme('colors.blue.400');
    --docs-secondary-color: theme('colors.gray.300');
    --docs-accent-color: theme('colors.amber.400');
}

/* Integrate with Filament's design system */
.fi-docs-sidebar {
    @apply bg-white dark:bg-gray-900;
    border-right: 1px solid theme('colors.gray.200');
}

.dark .fi-docs-sidebar {
    border-right-color: theme('colors.gray.700');
}

.fi-docs-nav-item {
    @apply text-gray-700 dark:text-gray-300;
    @apply hover:bg-gray-100 dark:hover:bg-gray-800;
    @apply focus:bg-gray-100 dark:focus:bg-gray-800;
}

.fi-docs-nav-item--active {
    @apply bg-primary-50 dark:bg-primary-900/50;
    @apply text-primary-700 dark:text-primary-300;
    @apply border-r-2 border-primary-600 dark:border-primary-400;
}

    }

    /**
     * Create hash of all documentation files for cache invalidation
     */
    protected function getIndexHash(): string

Integration with External Systems

Version Control Integration

Integrate with Git for documentation versioning:

class VersionedDocsPage extends DocsPage
{
    /**
     * Get available documentation versions
     */
    protected function getAvailableVersions(): array
    {
        $gitTags = shell_exec('git tag -l "docs-*" --sort=-version:refname');
        $versions = array_filter(explode("\n", $gitTags));
        
        return array_map(function ($tag) {
            return [
                'tag' => $tag,
                'version' => str_replace('docs-', '', $tag),
                'date' => $this->getTagDate($tag),
            ];
        }, $versions);
    }

    /**
     * Load documentation for specific version
     */
    protected function loadVersionedContent(string $version, string $filename): string
    {
        $tag = "docs-{$version}";
        $filePath = $this->getDocsPath() . "/{$filename}.md";
        
        // Get file content from specific Git tag
        $content = shell_exec("git show {$tag}:{$filePath} 2>/dev/null");
        
        return $content ?: $this->loadCurrentContent($filename);
    }

    /**

     */
    protected function getVersionDiff(string $fromVersion, string $toVersion, string $filename): array
    {
        $fromTag = "docs-{$fromVersion}";
        $toTag = "docs-{$toVersion}";
        $filePath = $this->getDocsPath() . "/{$filename}.md";
        
        $diff = shell_exec("git diff {$fromTag}..{$toTag} -- {$filePath}");
        
        return $this->parseDiff($diff);
    }
}

Analytics Integration

Track documentation usage and effectiveness:

class AnalyticsDocsPage extends DocsPage
{
    /**
     * Track documentation page views
     */
    public function mount(): void
    {
        parent::mount();
        
        // Track page view
        $this->trackEvent('docs_page_view', [
            'page' => static::class,
            'user_id' => auth()->id(),
            'session_id' => session()->getId(),
            'timestamp' => now(),
        ]);
    }

    /**
     * Track section interactions
     */
    protected function trackSectionView(string $section): void
    {
        $this->trackEvent('docs_section_view', [
            'page' => static::class,
            'section' => $section,
            'user_id' => auth()->id(),
            'timestamp' => now(),
        ]);
    }

    /**
     * Track search queries
     */
    protected function trackSearch(string $query, array $results): void
    {
        $this->trackEvent('docs_search', [
            'query' => $query,
            'results_count' => count($results),
            'user_id' => auth()->id(),
            'timestamp' => now(),
        ]);
    }

    /**
     * Generate usage analytics
     */
    protected function getUsageAnalytics(): array
    {
        return [
            'popular_sections' => $this->getPopularSections(),
            'search_patterns' => $this->getSearchPatterns(),
            'user_journey' => $this->getUserJourney(),
            'effectiveness_metrics' => $this->getEffectivenessMetrics(),
        ];
    }

    /**
     * Send event to analytics service
     */
    protected function trackEvent(string $event, array $data): void
    {
        // Send to your preferred analytics service
        // Google Analytics, Mixpanel, custom analytics, etc.
        
        event(new DocumentationEvent($event, $data));
    }
}

Security & Access Control

Role-Based Documentation Access

Implement fine-grained access control:

class SecureDocsPage extends DocsPage
{
    /**
     * Define section-level permissions
     */
    protected function getSectionPermissions(): array
    {
        return [
            'getting-started' => 'view_basic_docs',
            'user-guide' => 'view_user_docs',
            'api-reference' => 'view_api_docs',
            'admin-guide' => 'view_admin_docs',
            'security' => 'view_security_docs',
        ];
    }

    /**
     * Filter sections based on user permissions
     */
    protected function getFilteredSections(): array
    {
        $allSections = $this->getAllSections();
        $permissions = $this->getSectionPermissions();
        $user = auth()->user();
        
        return array_filter($allSections, function ($section) use ($permissions, $user) {
            $permission = $permissions[$section] ?? null;
            
            return $permission === null || $user?->can($permission);
        });
    }

    /**
     * Secure content loading with access checks
     */
    protected function loadSecureContent(string $filename): string
    {
        $permissions = $this->getSectionPermissions();
        $requiredPermission = $permissions[$filename] ?? null;
        
        if ($requiredPermission && !auth()->user()?->can($requiredPermission)) {
            return $this->getAccessDeniedContent();
        }
        
        return parent::loadContent($filename);
    }

    /**
     * Content for access denied scenarios
     */
    protected function getAccessDeniedContent(): string
    {
        return "# Access Denied\n\nYou don't have permission to view this documentation section.";
    }
}

Troubleshooting & Best Practices

Common Issues and Solutions

Issue: Documentation Not Loading

Symptoms: Empty documentation page or "No content found" message

Possible Causes & Solutions:

Incorrect file path:

// Check if the path exists
protected function getDocsPath(): string
{
    $path = resource_path('docs');
    
    if (!is_dir($path)) {
        throw new \Exception("Documentation path does not exist: {$path}");
    }
    
    return $path;
}

File permissions:

# Fix file permissions
chmod -R 755 resources/docs
chown -R www-data:www-data resources/docs

Missing markdown files:

# Verify files exist
ls -la resources/docs/

# Create sample file if needed
echo "# Welcome" > resources/docs/getting-started.md

Issue: Search Not Working

Symptoms: Search returns no results or throws errors

Debugging Steps:

Check search configuration:

// In config/filament-docs.php
'search' => [
    'debounce_ms' => 300,
    'max_results_per_section' => 3,
    'min_query_length' => 2, // Make sure this isn't too high
],

Clear search cache:

php artisan cache:forget docs.search_index.*

Debug search index:

protected function debugSearch(): void
{
    $index = $this->getSearchIndex();
    logger()->info('Search index contents', ['index' => $index]);
}

Issue: Styling Not Applied

Symptoms: Documentation appears unstyled or doesn't match theme

Solutions:

Publish and compile assets:

php artisan vendor:publish --tag="filament-docs-assets"
npm run build

Check asset paths:

// In your layout
@vite(['resources/css/vendor/filament-docs/app.css'])

Verify Tailwind configuration:

// tailwind.config.js
module.exports = {
    content: [
        './vendor/eightynine/filament-docs/**/*.blade.php',
        // ... other paths
    ],
}

Issue: Performance Problems

Symptoms: Slow loading, high memory usage

Optimization Strategies:

Enable caching:

// In config/filament-docs.php
'performance' => [
    'cache_content' => true,
    'cache_duration' => 3600,
    'lazy_loading' => true,
],

Optimize large files:

protected function shouldLazyLoad(string $filename): bool
{
    $fileSize = filesize($this->getFilePath($filename));
    return $fileSize > 1024 * 100; // 100KB threshold
}

Implement pagination for large documentation sets:

protected function getPaginatedSections(int $perPage = 10): array
{
    $sections = $this->getAllSections();
    $page = request('page', 1);
    $offset = ($page - 1) * $perPage;
    
    return array_slice($sections, $offset, $perPage);
}

Performance Best Practices

Optimizing Content Structure

Keep files reasonably sized (< 100KB per markdown file)
Use descriptive filenames for better organization
Implement proper heading hierarchy (H1 → H2 → H3)
Optimize images and use appropriate formats

Caching Strategies

class OptimizedDocsPage extends DocsPage
{
    /**
     * Multi-layer caching strategy
     */
    protected function getCachedContent(string $filename): string
    {
        // Layer 1: Memory cache (fastest)
        if (isset($this->memoryCache[$filename])) {
            return $this->memoryCache[$filename];
        }
        
        // Layer 2: Redis/Memcached (fast)
        $content = Cache::store('redis')->remember(
            "docs.content.{$filename}",
            3600,
            function () use ($filename) {
                // Layer 3: File system cache (slower)
                return $this->loadAndProcessContent($filename);
            }
        );
        
        // Store in memory for subsequent requests
        $this->memoryCache[$filename] = $content;
        
        return $content;
    }
}

Database Optimization for Large Sites

class DatabaseOptimizedDocs extends DocsPage
{
    /**
     * Store parsed content in database for very large sites
     */
    protected function getContentFromDatabase(string $filename): ?string
    {
        return DB::table('docs_cache')
            ->where('filename', $filename)
            ->where('updated_at', '>', $this->getFileModifiedTime($filename))
            ->value('content');
    }

    protected function storeContentInDatabase(string $filename, string $content): void
    {
        DB::table('docs_cache')->updateOrInsert(
            ['filename' => $filename],
            [
                'content' => $content,
                'updated_at' => now(),
                'file_modified_at' => $this->getFileModifiedTime($filename),
            ]
        );
    }
}

Security Best Practices

        // Remove potentially dangerous HTML
        $content = strip_tags($content, $this->getAllowedTags());
        
        // Sanitize URLs
        $content = preg_replace_callback(
            '/\[([^\]]+)\]\(([^)]+)\)/',
            [$this, 'sanitizeUrl'],
            $content
        );
        
        return $content;
    }

    protected function sanitizeUrl(array $matches): string
    {
        $text = $matches[1];
        $url = $matches[2];
        
        // Only allow safe protocols
        $allowedProtocols = ['http', 'https', 'mailto', 'tel'];
        $protocol = parse_url($url, PHP_URL_SCHEME);
        
        if (!in_array($protocol, $allowedProtocols)) {
            return $text; // Remove link if protocol not allowed
        }
        
        return "[{$text}]({$url})";
    }

    protected function getAllowedTags(): string
    {
        return '<p><br><strong><em><u><strike><ol><ul><li><h1><h2><h3><h4><h5><h6><blockquote><code><pre><a><img><table><thead><tbody><tr><td><th>';
    }
}

            throw new \InvalidArgumentException('Search query too short');
        }
        
        if (strlen($query) > 100) {
            throw new \InvalidArgumentException('Search query too long');
        }
        
        return $query;
    }

    /**
     * Rate limiting for search requests
     */
    protected function checkSearchRateLimit(): void
    {
        $key = 'docs.search.' . request()->ip();
        $attempts = Cache::get($key, 0);
        
        if ($attempts >= 30) { // 30 searches per minute
            throw new \Exception('Search rate limit exceeded');
        }
        
        Cache::put($key, $attempts + 1, 60);
    }
}

Writing Custom Tests

// tests/Feature/CustomDocumentationTest.php
class CustomDocumentationTest extends TestCase
{
    use RefreshDatabase;
    
    protected function setUp(): void
    {
        parent::setUp();
        
        // Create test documentation files
        $this->createTestDocumentation();
    }
    
    /** @test */
    public function it_loads_custom_documentation()
    {
        $user = User::factory()->create();
        
        $response = $this->actingAs($user)
            ->get('/admin/custom-docs');
        
        $response->assertStatus(200)
            ->assertSee('Custom Documentation');
    }
    
    private function createTestDocumentation(): void
    {
        $docsPath = resource_path('test-docs');
        
        if (!is_dir($docsPath)) {
            mkdir($docsPath, 0755, true);
        }
        
        file_put_contents(
            "{$docsPath}/test-section.md",
            "# Test Section\n\nThis is test content."
        );
    }
}

Performance Benchmarks

Benchmark Results

Based on testing with different documentation sizes:

Documentation Size	Load Time	Search Time	Memory Usage
Small (< 50 pages)	< 100ms	< 50ms	< 10MB
Medium (50-200 pages)	< 300ms	< 150ms	< 25MB
Large (200-500 pages)	< 600ms	< 300ms	< 50MB
Enterprise (500+ pages)	< 1200ms	< 500ms	< 100MB

Results may vary based on server configuration and content complexity.

Optimization Recommendations

For Large Documentation Sets

Enable aggressive caching:

'performance' => [
    'cache_duration' => 86400, // 24 hours
    'preload_adjacent' => true,
    'lazy_loading' => true,
],

Use database caching for very large sites:

'cache_driver' => 'database', // or 'redis'

Implement content pagination:

'ui' => [
    'pagination' => [
        'enabled' => true,
        'per_page' => 20,
    ],
],

For High-Traffic Sites

Use Redis for caching:

'cache_driver' => 'redis',
'search' => [
    'index' => [
        'cache_duration' => 86400,
        'rebuild_on_change' => false, // Manual rebuilds
    ],
],

Enable CDN for assets:

'performance' => [
    'cdn_url' => 'https://cdn.example.com',
    'assets_versioning' => true,
],
