## 🚀 Installation

```bash
pnpm add @serve.zone/interfaces
```

## 🏗️ Interface Categories

### 📡 Request/Response Interfaces

Typed contracts for API communication:

```typescript
import { 
  IRequest_GetAllImages,
  IRequest_CreateCluster,
  IRequest_DeployService 
} from '@serve.zone/interfaces';

// Type-safe request
const request: IRequest_GetAllImages['request'] = {
  identity: userIdentity,
  filters: {
    tag: 'production'
  }
};

// Type-safe response
const response: IRequest_GetAllImages['response'] = {
  images: [...]
};
```

### 📦 Data Models

Core data structures for Cloudly entities:

```typescript
import { 
  ICluster, 
  IService, 
  IImage, 
  ISecret,
  IServer 
} from '@serve.zone/interfaces';

// Define a service
const service: IService = {
  id: 'service-123',
  data: {
    name: 'api-service',
    imageId: 'image-456',
    imageVersion: '2.0.0',
    environment: {
      NODE_ENV: 'production'
    },
    scaleFactor: 3,
    balancingStrategy: 'round-robin',
    ports: {
      web: 80,
      metrics: 9090
    },
    domains: [
      { name: 'api.example.com' }
    ],
    deploymentIds: [],
    deploymentDirectiveIds: []
  }
};
```

### 🔐 Authentication & Identity

Identity management interfaces:

```typescript
import { 
  IIdentity, 
  IServiceToken,
  IPermission 
} from '@serve.zone/interfaces';

const identity: IIdentity = {
  id: 'user-789',
  name: 'service-account',
  type: 'service',
  permissions: ['cluster:read', 'service:write'],
  tokenHash: 'hashed-token',
  metadata: {
    createdAt: new Date(),
    lastAccess: new Date()
  }
};
```

### 🌐 Network Configuration

Networking and routing interfaces:

```typescript
import { 
  IReverseProxyConfig,
  IDomainConfig,
  ILoadBalancerConfig 
} from '@serve.zone/interfaces';

const proxyConfig: IReverseProxyConfig = {
  domain: 'app.example.com',
  path: '/api',
  serviceAddress: 'http://api-service:3000',
  ssl: true,
  headers: {
    'X-Real-IP': '$remote_addr'
  }
};
```

### 📊 Monitoring & Metrics

Observability interfaces:

```typescript
import { 
  IServerMetrics,
  IServiceMetrics,
  IClusterHealth 
} from '@serve.zone/interfaces';

const metrics: IServerMetrics = {
  serverId: 'server-001',
  cpuUsageInPercent: 65,
  memoryUsageinMB: 3072,
  memoryAvailableInMB: 8192,
  diskUsageInPercent: 40,
  networkInMbps: 100,
  networkOutMbps: 150,
  containerCount: 12,
  containerMetrics: [...]
};
```

### 🔒 Secret Management

Security and credential interfaces:

```typescript
import { 
  ISecretGroup,
  ISecretBundle,
  IEncryptedData 
} from '@serve.zone/interfaces';

const secretGroup: ISecretGroup = {
  id: 'secrets-123',
  name: 'database-credentials',
  secrets: [
    {
      key: 'DB_HOST',
      value: 'encrypted-value',
      encrypted: true
    },
    {
      key: 'DB_PASSWORD',
      value: 'encrypted-value',
      encrypted: true
    }
  ],
  metadata: {
    environment: 'production',
    service: 'api'
  }
};
```

## 📚 Common Usage Patterns

### Creating Type-Safe API Clients

```typescript
import { 
  IRequest_CreateService,
  IService 
} from '@serve.zone/interfaces';

class ServiceClient {
  async createService(
    serviceData: IService['data']
  ): Promise<IService> {
    const request: IRequest_CreateService['request'] = {
      identity: this.identity,
      serviceData
    };
    
    const response = await this.client.send<IRequest_CreateService>(
      'createService',
      request
    );
    
    return response.service;
  }
}
```

### Validating Incoming Data

```typescript
import { ICluster } from '@serve.zone/interfaces';
import { validateType } from 'your-validation-library';

function validateClusterData(data: unknown): ICluster {
  if (!validateType<ICluster>(data)) {
    throw new Error('Invalid cluster data');
  }
  return data;
}
```

### Building Configuration Objects

```typescript
import { 
  ICloudlyConfig,
  IMongoDescriptor 
} from '@serve.zone/interfaces';

const config: ICloudlyConfig = {
  cfToken: process.env.CF_TOKEN!,
  hetznerToken: process.env.HETZNER_TOKEN!,
  environment: 'production',
  letsEncryptEmail: 'certs@example.com',
  publicUrl: 'cloudly.example.com',
  publicPort: 443,
  mongoDescriptor: {
    mongoDbUrl: process.env.MONGO_URL!,
    mongoDbName: 'cloudly',
    mongoDbUser: process.env.MONGO_USER!,
    mongoDbPass: process.env.MONGO_PASS!
  }
};
```

## 🎯 Advanced Features

### Generic Request Handler

```typescript
import { ITypedRequest } from '@serve.zone/interfaces';

class RequestHandler {
  async handle<T extends ITypedRequest>(
    request: T['request']
  ): Promise<T['response']> {
    // Type-safe request handling
    return this.processRequest(request);
  }
}
```

### Discriminated Unions

```typescript
import { IDeploymentStatus } from '@serve.zone/interfaces';

function handleStatus(status: IDeploymentStatus) {
  switch (status.type) {
    case 'pending':
      console.log('Deployment pending...');
      break;
    case 'running':
      console.log(`Running on ${status.serverId}`);
      break;
    case 'failed':
      console.log(`Failed: ${status.error}`);
      break;
  }
}
```

### Extending Interfaces

```typescript
import { IService } from '@serve.zone/interfaces';

interface IExtendedService extends IService {
  customMetadata: {
    team: string;
    costCenter: string;
    sla: 'standard' | 'premium';
  };
}
```

## 📖 Interface Documentation

All interfaces include comprehensive JSDoc comments:

```typescript
/**
 * Represents a cluster configuration
 * @interface ICluster
 */
export interface ICluster {
  /**
   * Unique identifier for the cluster
   * @type {string}
   */
  id: string;
  
  /**
   * Cluster configuration data
   * @type {IClusterData}
   */
  data: IClusterData;
}
```

## 🛠️ Development Tips

### Import Organization

```typescript
// Group imports by category
import { 
  // Data models
  ICluster,
  IService,
  IImage,
  
  // Requests
  IRequest_CreateCluster,
  IRequest_DeployService,
  
  // Configuration
  ICloudlyConfig,
  IReverseProxyConfig
} from '@serve.zone/interfaces';
```

### Type Guards

```typescript
import { IService, ICluster } from '@serve.zone/interfaces';

function isService(entity: IService | ICluster): entity is IService {
  return 'imageId' in entity.data;
}
```
