🚀 Getting Started

🏗️ Architecture Overview

Lexicon Structure

The SDK uses a well-organized namespace structure that mirrors the AT Protocol's lexicon hierarchy:

use Atproto\Lexicons\{
    App\Bsky\Feed\Post,           // app.bsky.feed.post
    App\Bsky\Actor\Profile,       // app.bsky.actor.profile
    Com\Atproto\Repo\CreateRecord // com.atproto.repo.createRecord
};

NSID (Namespaced Identifier)

Each operation in the SDK corresponds to a specific NSID (Namespaced Identifier) in the AT Protocol. For example:

- app.bsky.feed.post            -> Atproto\Lexicons\App\Bsky\Feed\Post
- app.bsky.actor.getProfile     -> Atproto\Lexicons\App\Bsky\Actor\GetProfile

Smart Builder Pattern

The SDK implements a smart builder pattern using method chaining. This provides an intuitive way to construct API requests:

$response = $client->app()      // Navigate to 'app' namespace
    ->bsky()            // Navigate to 'bsky' subspace
    ->feed()            // Navigate to 'feed' operations
    ->post()            // Select 'post' operation
    ->forge()           // Initialize the request builder
    ->text("Hello!")    // Add content
    ->send();           // Execute the request

Response Handling

The SDK uses type-safe response objects that automatically cast API responses into convenient PHP objects:

// Getting a profile
$profile = $client->app()
    ->bsky()
    ->actor()
    ->getProfile()
    ->forge()
    ->actor('user.bsky.social')
    ->send();

// Access data through typed methods
echo $profile->displayName();    // Returns string
echo $profile->followersCount(); // Returns int

/** @var \Carbon\Carbon $createdAt */
$createdAt = $profile->createdAt();      // Returns Carbon instance

// Response objects are iterable when representing collections
/** @var \Atproto\Responses\Objects\FollowersObject $followers */
$followers = $client->app()
    ->bsky()
    ->graph()
    ->getFollowers()
    ->forge()
    ->actor('user.bsky.social')
    ->send();

foreach ($followers as $follower) {
    // Each $follower is a typed object with guaranteed methods
    /** @var \Atproto\Responses\Objects\FollowerObject $follower */
    
    echo sprintf(
        "%s joined on %s\n",
        $follower->handle(),
        $follower->createdAt()->format('Y-m-d')
    );
}

Authentication

The first step to using the SDK is establishing a connection with BlueSky's servers. The SDK provides a straightforward authentication process:

use Atproto\Client;

$client = new Client();

// Basic authentication
$client->authenticate('your.identifier', 'your-password');

// Or using environment variables (recommended)
$client->authenticate(
    getenv('BLUESKY_IDENTIFIER'),
    getenv('BLUESKY_PASSWORD')
);

📝 Content Creation

Rich Text Posts

The SDK excels at creating engaging social media content with rich text features. Here's a comprehensive guide to creating various types of posts:

Marketing Campaign Example

Perfect for social media managers running promotional campaigns:

// Announcing a special promotion
$client->app()
    ->bsky()
    ->feed()
    ->post()
    ->forge()
    ->text(
        "🎉 Summer Sale Spectacular! 🌞\n\n",
        "Get ready for amazing deals on all our premium products! ",
        RichText::link('https://yourstore.com/summer-sale', 'Shop Now'),
        "\n\n✨ Highlights:\n",
        "• Up to 50% off on selected items\n",
        "• Free shipping worldwide\n",
        "• Limited time offers\n\n",
        "Questions? Ask ",
        RichText::mention('did:plc:support', 'our support team'),
        "!\n\n",
        RichText::tag('SummerSale', 'SummerSale'),
        " ",
        RichText::tag('ShopNow', 'ShopNow')
    )
    ->send();

Tech Tutorial Series

Ideal for educational content and technical blogs:

// Upload tutorial screenshot
$tutorialImage = $client->com()
    ->atproto()
    ->repo()
    ->uploadBlob()
    ->forge()
    ->token($client->authenticated()->accessJwt())
    ->blob('path/to/tutorial-screenshot.jpg')
    ->send()
    ->blob();

// Create in-depth tutorial post
$client->app()
    ->bsky()
    ->feed()
    ->post()
    ->forge()
    ->text(
        "📘 PHP Best Practices Guide: Part 1\n\n",
        "Today we're diving into modern PHP development. ",
        "First in our series about building robust applications.\n\n",
        "Key topics covered:\n",
        "1. Dependency Injection\n",
        "2. Service Containers\n",
        "3. Repository Pattern\n\n",
        "Full tutorial: ",
        RichText::link('https://blog.dev/php-best-practices', 'Read More'),
        "\n\nSpecial thanks to ",
        RichText::mention('did:plc:reviewer', 'our technical reviewer'),
        " for the insights!\n\n",
        RichText::tag('PHP', 'PHP'),
        " ",
        RichText::tag('WebDev', 'WebDev'),
        " ",
        RichText::tag('Coding', 'Coding')
    )
    ->embed(new ImageCollection([
        new Image($tutorialImage, "Code example showing dependency injection in PHP")
    ]))
    ->send();

👥 Community Management

Profile Analytics

The SDK provides powerful tools for managing and analyzing user profiles. Here's how to build a simple analytics system:

use GenericCollection\Collection;
use GenericCollection\Types\Primitive\StringType;

class CommunityAnalytics {
    private $client;
    
    public function __construct(Client $client) {
        $this->client = $client;
    }
    
    public function analyzeTeamProfiles() {
        // Get team members' profiles
        $teamHandles = new Collection(StringType::class, [
            'lead.dev.bsky.social',
            'frontend.dev.bsky.social',
            'backend.dev.bsky.social',
            'design.bsky.social'
        ]);
        
        $profiles = $this->client->app()
            ->bsky()
            ->actor()
            ->getProfiles()
            ->forge()
            ->actors($teamHandles)
            ->send();
            
        // Analyze profile data
        $analytics = [];
        foreach ($profiles as $profile) {
            $analytics[] = [
                'name' => $profile->displayName(),
                'followers' => $profile->followersCount(),
                'posts' => $profile->postsCount(),
                'engagement_rate' => $this->calculateEngagement($profile)
            ];
        }
        
        return $analytics;
    }
    
    private function calculateEngagement($profile) {
        // Custom engagement calculation logic
        return ($profile->followersCount() * $profile->postsCount()) / 100;
    }
}

Follower Engagement System

Create meaningful interactions with your community:

class FollowerEngagement {
    private $client;
    
    public function __construct(Client $client) {
        $this->client = $client;
    }
    
    public function welcomeNewFollowers() {
        $followers = $this->client->app()
            ->bsky()
            ->graph()
            ->getFollowers()
            ->forge()
            ->actor($this->client->authenticated()->did())
            ->send();
            
        $newFollowers = $this->filterTodaysFollowers($followers);
        
        foreach ($newFollowers as $follower) {
            $this->sendWelcomeMessage($follower);
        }
    }
    
    private function sendWelcomeMessage($follower) {
        $this->client->app()
            ->bsky()
            ->feed()
            ->post()
            ->forge()
            ->text(
                "👋 Welcome to our community ",
                RichText::mention($follower->did(), $follower->handle()),
                "!\n\n",
                "We're excited to have you here. ",
                "Check out our pinned posts for community guidelines ",
                "and ongoing discussions.\n\n",
                "Feel free to introduce yourself in the comments! 🌟"
            )
            ->send();
    }
}

🎨 Advanced Content Strategies

Content Calendar Integration

Example of how to integrate the SDK with a content calendar system:

class ContentScheduler {
    private $client;
    
    public function __construct(Client $client) {
        $this->client = $client;
    }
    
    public function schedulePost($content, $images = [], $scheduledTime) {
        // Prepare image uploads if any
        $uploadedImages = [];
        foreach ($images as $image) {
            $uploadedBlob = $this->client->com()
                ->atproto()
                ->repo()
                ->uploadBlob()
                ->forge()
                ->token($this->client->authenticated()->accessJwt())
                ->blob($image['path'])
                ->send()
                ->blob();
                
            $uploadedImages[] = new Image($uploadedBlob, $image['description']);
        }
        
        // Create the post
        $post = $this->client->app()
            ->bsky()
            ->feed()
            ->post()
            ->forge()
            ->text(...$this->formatContent($content));
            
        // Add images if any
        if (!empty($uploadedImages)) {
            $post->embed(new ImageCollection($uploadedImages));
        }
        
        return $post->send();
    }
    
    private function formatContent($content) {
        // Transform content into rich text components
        // Implementation depends on your content structure
    }
}

🛠️ Error Handling & Best Practices

The SDK provides comprehensive error handling to ensure your application gracefully handles any issues:

use Atproto\Exceptions\{
    InvalidArgumentException,
    Auth\AuthRequired,
    Http\MissingFieldProvidedException
};

class PostManager {
    private $client;
    
    public function __construct(Client $client) {
        $this->client = $client;
    }
    
    public function createSafePost($content) {
        try {
            return $this->client->app()
                ->bsky()
                ->feed()
                ->post()
                ->forge()
                ->text($content)
                ->send();
                
        } catch (AuthRequired $e) {
            // Handle authentication issues
            $this->logError('Authentication failed', $e);
            $this->refreshAuthentication();
            
        } catch (MissingFieldProvidedException $e) {
            // Handle missing required fields
            $this->logError('Missing required field', $e);
            throw new ValidationException("Post creation failed: {$e->getMessage()}");
            
        } catch (InvalidArgumentException $e) {
            // Handle invalid input
            $this->logError('Invalid input provided', $e);
            throw new ValidationException("Invalid post content: {$e->getMessage()}");
        }
    }
}

🧪 Testing

The SDK comes with comprehensive testing tools to ensure your integration works flawlessly:

# Run complete test suite
composer test

# Run specific test suites
