The powerful API client for Cloudly. Connect your applications to multi-cloud infrastructure with type-safe, real-time communication.

🎯 What is @serve.zone/api?

This is your programmatic gateway to the Cloudly platform. Built with TypeScript, it provides a robust, type-safe interface for managing cloud resources, orchestrating containers, and automating infrastructure operations.

✨ Features

• 🔒 Type-Safe - Full TypeScript support with comprehensive interfaces
• ⚡ Real-Time - WebSocket-based communication for instant updates
• 🔑 Secure Authentication - Token-based identity management
• 📦 Resource Management - Complete control over clusters, images, and services
• 🎭 Multi-Identity - Support for service accounts and user authentication
• 🔄 Reactive Streams - RxJS integration for event-driven programming

🚀 Installation

pnpm add @serve.zone/api

🎬 Quick Start

import { CloudlyApiClient } from '@serve.zone/api';

// Initialize the client
const client = new CloudlyApiClient({
  registerAs: 'api',
  cloudlyUrl: 'https://cloudly.example.com:443'
});

// Start the connection
await client.start();

// Authenticate with a service token
const identity = await client.getIdentityByToken('your-service-token', {
  tagConnection: true,
  statefullIdentity: true
});

console.log('🎉 Connected as:', identity.name);

🔐 Authentication

Service Token Authentication

// Authenticate using a service token
const identity = await client.getIdentityByToken(serviceToken, {
  tagConnection: true,        // Tag this connection with the identity
  statefullIdentity: true     // Maintain state across reconnections
});

Identity Management

// Get current identity
const currentIdentity = client.identity;

// Check permissions
if (currentIdentity.permissions.includes('cluster:write')) {
  // Perform cluster operations
}

📚 Core Operations

🐳 Image Management

// Create an image entry
const image = await client.images.createImage({
  name: 'my-app',
  description: 'Production application image'
});

// Push a new version
const imageStream = fs.createReadStream('app.tar');
await image.pushImageVersion('2.0.0', imageStream);

// List all images
const images = await client.images.listImages();

🌐 Cluster Operations

// Get cluster configuration
const clusterConfig = await client.getClusterConfigFromCloudlyByIdentity(identity);

// Deploy to cluster
await client.deployToCluster({
  clusterName: 'production',
  serviceName: 'api-service',
  image: 'my-app:2.0.0',
  replicas: 3
});

🔒 Certificate Management

// Request SSL certificate
const certificate = await client.getCertificateForDomain({
  domainName: 'api.example.com',
  type: 'ssl',
  identity: identity
});

// Use certificate in your application
console.log('Certificate:', certificate.cert);
console.log('Private Key:', certificate.key);

🔐 Secret Management

// Create secret group
const secretGroup = await client.secrets.createSecretGroup({
  name: 'api-secrets',
  secrets: [
    { key: 'DATABASE_URL', value: 'postgres://...' },
    { key: 'REDIS_URL', value: 'redis://...' }
  ]
});

// Retrieve secrets
const secrets = await client.secrets.getSecretGroup('api-secrets');

🔄 Real-Time Updates

Subscribe to configuration changes and server actions using RxJS:

// Listen for configuration updates
client.configUpdateSubject.subscribe({
  next: (config) => {
    console.log('📡 Configuration updated:', config);
    // React to configuration changes
  }
});

// Handle server action requests
client.serverActionSubject.subscribe({
  next: (action) => {
    console.log('⚡ Server action:', action.type);
    // Process server-initiated actions
  }
});

🎯 Advanced Usage

Streaming Operations

// Stream logs from a service
const logStream = await client.logs.streamLogs({
  service: 'api-service',
  follow: true
});

logStream.on('data', (log) => {
  console.log(log.message);
});

Batch Operations

// Deploy multiple services
const deployments = await Promise.all([
  client.deploy({ service: 'frontend', image: 'app:latest' }),
  client.deploy({ service: 'backend', image: 'api:latest' }),
  client.deploy({ service: 'worker', image: 'worker:latest' })
]);

Error Handling

try {
  await client.start();
} catch (error) {
  if (error.code === 'AUTH_FAILED') {
    console.error('Authentication failed:', error.message);
  } else if (error.code === 'CONNECTION_LOST') {
    console.error('Connection lost, retrying...');
    await client.reconnect();
  }
}

🧹 Cleanup

Always gracefully disconnect when done:

// Stop the client connection
await client.stop();
console.log('✅ Disconnected cleanly');
