### Message Patterns ### Message Patterns
#### 🔥 Fire and Forget #### 🔥 Fire and Forget
Fast, one-way messaging when you don't need a response: Send messages without waiting for a response:
```typescript ```typescript
// Server // Server
server.onMessage('log', (data, clientId) => { server.onMessage('log', (data, clientId) => {
console.log(`[${clientId}]:`, data.message); console.log(`[${clientId}] ${data.level}:`, data.message);
// No return value needed // No return needed
}); });
// Client // Client
await client.sendMessage('log', { await client.sendMessage('log', {
level: 'info',
message: 'User logged in', message: 'User logged in',
timestamp: Date.now() timestamp: Date.now()
}); });
``` ```
#### 📞 Request/Response #### 📞 Request/Response
RPC-style communication with timeouts and type safety: RPC-style communication with type safety:
```typescript ```typescript
// Server - Define your handler with types interface UserRequest {
interface CalculateRequest { userId: string;
operation: 'add' | 'multiply'; fields?: string[];
values: number[];
} }
interface CalculateResponse { interface UserResponse {
result: number; id: string;
computedAt: number; name: string;
email?: string;
createdAt: number;
} }
server.onMessage<CalculateRequest, CalculateResponse>('calculate', async (data) => { // Server
const result = data.operation === 'add' server.onMessage<UserRequest, UserResponse>('getUser', async (data) => {
? data.values.reduce((a, b) => a + b, 0) const user = await db.getUser(data.userId);
: data.values.reduce((a, b) => a * b, 1);
return { return {
result, id: user.id,
computedAt: Date.now() name: user.name,
email: data.fields?.includes('email') ? user.email : undefined,
createdAt: user.createdAt
}; };
}); });
// Client - Type-safe request // Client - with timeout
const response = await client.request<CalculateRequest, CalculateResponse>( const user = await client.request<UserRequest, UserResponse>(
'calculate', 'getUser',
{ operation: 'add', values: [1, 2, 3, 4, 5] }, { userId: '123', fields: ['email'] },
{ timeout: 5000 } { timeout: 5000 }
); );
console.log(`Sum is ${response.result}`);
``` ```
#### 📢 Pub/Sub Pattern #### 📢 Pub/Sub Pattern
Topic-based message broadcasting: Topic-based message broadcasting:
```typescript ```typescript
// Server automatically handles subscriptions // Subscribers
const publisher = SmartIpc.createClient({
id: 'events-service',
clientId: 'publisher'
});
const subscriber1 = SmartIpc.createClient({ const subscriber1 = SmartIpc.createClient({
id: 'events-service', id: 'events-service',
clientId: 'subscriber-1' socketPath: '/tmp/events.sock'
}); });
const subscriber2 = SmartIpc.createClient({ await subscriber1.connect();
id: 'events-service',
clientId: 'subscriber-2'
});
// Subscribe to topics
await subscriber1.subscribe('user.login', (data) => { await subscriber1.subscribe('user.login', (data) => {
console.log('User logged in:', data); console.log('User logged in:', data);
}); });
await subscriber2.subscribe('user.*', (data) => { // Publisher
console.log('User event:', data); const publisher = SmartIpc.createClient({
id: 'events-service',
socketPath: '/tmp/events.sock'
}); });
// Publish events await publisher.connect();
await publisher.publish('user.login', { await publisher.publish('user.login', {
userId: '123', userId: '123',
ip: '192.168.1.1',
timestamp: Date.now() timestamp: Date.now()
}); });
``` ```
## Advanced Features ## 💪 Advanced Features
### 🔄 Auto-Reconnection with Exponential Backoff ### 🏁 Server Readiness Detection
Clients automatically reconnect on connection loss: Eliminate race conditions in tests and production:
```typescript
const server = SmartIpc.createServer({
id: 'my-service',
socketPath: '/tmp/my-service.sock',
autoCleanupSocketFile: true
});
// Option 1: Wait for full readiness
await server.start({ readyWhen: 'accepting' });
// Server is now FULLY ready to accept connections
// Option 2: Use ready event
server.on('ready', () => {
console.log('Server is ready!');
startClients();
});
await server.start();
// Option 3: Check readiness state
if (server.getIsReady()) {
console.log('Ready to rock! 🎸');
}
```
### 🔄 Smart Connection Retry
Never lose messages due to temporary connection issues:
```typescript ```typescript
const client = SmartIpc.createClient({ const client = SmartIpc.createClient({
id: 'resilient-service', id: 'resilient-client',
clientId: 'auto-reconnect-client', socketPath: '/tmp/service.sock',
reconnect: { connectRetry: {
enabled: true, enabled: true,
initialDelay: 1000, // Start with 1 second initialDelay: 100, // Start with 100ms
maxDelay: 30000, // Cap at 30 seconds maxDelay: 1500, // Cap at 1.5 seconds
factor: 2, // Double each time maxAttempts: 20, // Try 20 times
maxAttempts: Infinity // Keep trying forever totalTimeout: 15000 // Give up after 15 seconds total
} },
registerTimeoutMs: 8000 // Registration handshake timeout
}); });
// Monitor connection state // Will retry automatically if server isn't ready yet
client.on('connected', () => console.log('Connected! 🟢')); await client.connect({
client.on('disconnected', () => console.log('Connection lost! 🔴')); waitForReady: true, // Wait for server to exist
client.on('reconnecting', (attempt) => console.log(`Reconnecting... Attempt ${attempt} 🟡`)); waitTimeout: 10000 // Wait up to 10 seconds
});
``` ```
### 💓 Heartbeat Monitoring ### 💓 Graceful Heartbeat Monitoring
Keep connections alive and detect failures quickly: Keep connections alive without crashing on timeouts:
```typescript ```typescript
const server = SmartIpc.createServer({ const server = SmartIpc.createServer({
id: 'monitored-service', id: 'monitored-service',
heartbeat: { socketPath: '/tmp/monitored.sock',
enabled: true, heartbeat: true,
interval: 5000, // Send heartbeat every 5 seconds heartbeatInterval: 3000,
timeout: 15000 // Consider dead after 15 seconds heartbeatTimeout: 10000,
} heartbeatInitialGracePeriodMs: 5000, // Grace period for startup
heartbeatThrowOnTimeout: false // Emit event instead of throwing
}); });
// Clients automatically respond to heartbeats server.on('heartbeatTimeout', (clientId) => {
console.log(`Client ${clientId} heartbeat timeout - will handle gracefully`);
});
// Client configuration
const client = SmartIpc.createClient({ const client = SmartIpc.createClient({
id: 'monitored-service', id: 'monitored-service',
clientId: 'heartbeat-client', socketPath: '/tmp/monitored.sock',
heartbeat: true // Enable heartbeat responses heartbeat: true,
heartbeatInterval: 3000,
heartbeatTimeout: 10000,
heartbeatInitialGracePeriodMs: 5000,
heartbeatThrowOnTimeout: false
});
client.on('heartbeatTimeout', () => {
console.log('Heartbeat timeout detected, reconnecting...');
// Handle reconnection logic
}); });
``` ```
### 📊 Real-time Metrics & Observability ### 🧹 Automatic Socket Cleanup
Track performance and connection health: Never worry about stale socket files:
```typescript ```typescript
// Server metrics const server = SmartIpc.createServer({
id: 'clean-service',
socketPath: '/tmp/service.sock',
autoCleanupSocketFile: true, // Remove stale socket on start
socketMode: 0o600 // Set socket permissions (Unix only)
});
// Socket file will be cleaned up automatically on start
await server.start();
```
### 📊 Real-time Metrics
Monitor your IPC performance:
```typescript
// Server stats
const serverStats = server.getStats(); const serverStats = server.getStats();
console.log({ console.log({
isRunning: serverStats.isRunning, isRunning: serverStats.isRunning,
connectedClients: serverStats.connectedClients, connectedClients: serverStats.connectedClients,
totalConnections: serverStats.totalConnections, totalConnections: serverStats.totalConnections,
uptime: serverStats.uptime,
metrics: { metrics: {
messagesSent: serverStats.metrics.messagesSent, messagesSent: serverStats.metrics.messagesSent,
messagesReceived: serverStats.metrics.messagesReceived, messagesReceived: serverStats.metrics.messagesReceived,
bytesSent: serverStats.metrics.bytesSent,
bytesReceived: serverStats.metrics.bytesReceived,
errors: serverStats.metrics.errors errors: serverStats.metrics.errors
} }
}); });
// Client metrics // Client stats
const clientStats = client.getStats(); const clientStats = client.getStats();
console.log({ console.log({
connected: clientStats.connected, connected: clientStats.connected,
reconnectAttempts: clientStats.reconnectAttempts, reconnectAttempts: clientStats.reconnectAttempts,
lastActivity: clientStats.lastActivity,
metrics: clientStats.metrics metrics: clientStats.metrics
}); });
// Track specific clients on server // Get specific client info
const clientInfo = server.getClientInfo('client-1'); const clientInfo = server.getClientInfo('client-123');
console.log({ console.log({
clientId: clientInfo.clientId, connectedAt: new Date(clientInfo.connectedAt),
metadata: clientInfo.metadata, lastActivity: new Date(clientInfo.lastActivity),
connectedAt: clientInfo.connectedAt, metadata: clientInfo.metadata
lastActivity: clientInfo.lastActivity,
subscriptions: clientInfo.subscriptions
}); });
``` ```
### 🛡️ Security & Limits ### 🎯 Broadcasting
Protect against malicious or misbehaving clients: Send messages to multiple clients:
```typescript
const secureServer = SmartIpc.createServer({
id: 'secure-service',
maxMessageSize: 10 * 1024 * 1024, // 10MB max message size
maxConnections: 100, // Limit concurrent connections
connectionTimeout: 60000, // Drop idle connections after 1 minute
// Authentication (coming soon)
auth: {
required: true,
validator: async (token) => {
// Validate auth token
return validateToken(token);
}
}
});
// Rate limiting per client
secureServer.use(rateLimitMiddleware({
windowMs: 60000, // 1 minute window
max: 100 // 100 requests per window
}));
```
### 🎯 Broadcast to Specific Clients
Send targeted messages:
```typescript ```typescript
// Broadcast to all connected clients // Broadcast to all connected clients
server.broadcast('system-alert', { await server.broadcast('announcement', {
message: 'Maintenance in 5 minutes' message: 'Server will restart in 5 minutes',
severity: 'warning'
}); });
// Send to specific client // Send to specific clients
server.sendToClient('client-1', 'personal-message', { await server.broadcastTo(
content: 'This is just for you' ['client-1', 'client-2'],
}); 'private-message',
{ content: 'This is just for you two' }
);
// Send to multiple specific clients // Send to one client
server.sendToClients(['client-1', 'client-2'], 'group-message', { await server.sendToClient('client-1', 'direct', {
content: 'Group notification' data: 'Personal message'
}); });
// Get all connected client IDs
const clients = server.getConnectedClients();
console.log('Connected clients:', clients);
``` ```
## Error Handling ## 🧪 Testing Utilities
Comprehensive error handling with typed errors: SmartIPC includes powerful helpers for testing:
### Wait for Server
```typescript ```typescript
import { IpcError, ConnectionError, TimeoutError } from '@push.rocks/smartipc'; import { SmartIpc } from '@push.rocks/smartipc';
// Client error handling // Start your server in another process
const serverProcess = spawn('node', ['server.js']);
// Wait for it to be ready
await SmartIpc.waitForServer({
socketPath: '/tmp/test.sock',
timeoutMs: 10000
});
// Now safe to connect clients
const client = SmartIpc.createClient({
id: 'test-client',
socketPath: '/tmp/test.sock'
});
await client.connect();
```
### Spawn and Connect
```typescript
// Helper that spawns a server and connects a client
const { client, serverProcess } = await SmartIpc.spawnAndConnect({
serverScript: './server.js',
socketPath: '/tmp/test.sock',
clientId: 'test-client',
connectRetry: {
enabled: true,
maxAttempts: 10
}
});
// Use the client
const response = await client.request('ping', {});
// Cleanup
await client.disconnect();
serverProcess.kill();
```
## 🎭 Event Handling
SmartIPC provides comprehensive event emitters:
```typescript
// Server events
server.on('start', () => console.log('Server started'));
server.on('ready', () => console.log('Server ready for connections'));
server.on('clientConnect', (clientId, metadata) => {
console.log(`Client ${clientId} connected with metadata:`, metadata);
});
server.on('clientDisconnect', (clientId) => {
console.log(`Client ${clientId} disconnected`);
});
server.on('error', (error, clientId) => {
console.error(`Error from ${clientId}:`, error);
});
// Client events
client.on('connect', () => console.log('Connected to server'));
client.on('disconnect', () => console.log('Disconnected from server'));
client.on('reconnecting', (attempt) => {
console.log(`Reconnection attempt ${attempt}`);
});
client.on('error', (error) => { client.on('error', (error) => {
if (error instanceof ConnectionError) { console.error('Client error:', error);
console.error('Connection failed:', error.message); });
} else if (error instanceof TimeoutError) { client.on('heartbeatTimeout', (error) => {
console.error('Request timed out:', error.message); console.warn('Heartbeat timeout:', error);
});
```
## 🛡️ Error Handling
Robust error handling with detailed error information:
```typescript
// Client-side error handling
try {
const response = await client.request('riskyOperation', data, {
timeout: 5000
});
} catch (error) {
if (error.message.includes('timeout')) {
console.error('Request timed out');
} else if (error.message.includes('Failed to register')) {
console.error('Could not register with server');
} else { } else {
console.error('Unknown error:', error); console.error('Unknown error:', error);
} }
});
// Server error handling
server.on('client-error', (clientId, error) => {
console.error(`Client ${clientId} error:`, error);
// Optionally disconnect misbehaving clients
if (error.code === 'INVALID_MESSAGE') {
server.disconnectClient(clientId);
}
});
// Request with error handling
try {
const response = await client.request('risky-operation', data, {
timeout: 5000,
retries: 3
});
} catch (error) {
if (error instanceof TimeoutError) {
// Handle timeout
} else {
// Handle other errors
}
} }
```
## Testing // Server-side error boundaries
server.onMessage('process', async (data, clientId) => {
SmartIPC includes comprehensive testing utilities: try {
return await riskyProcessing(data);
```typescript } catch (error) {
import { createTestServer, createTestClient } from '@push.rocks/smartipc/testing'; console.error(`Processing failed for ${clientId}:`, error);
throw error; // Will be sent back to client as error
describe('My IPC integration', () => { }
let server, client;
beforeEach(async () => {
server = await createTestServer();
client = await createTestClient(server);
});
afterEach(async () => {
await client.disconnect();
await server.stop();
});
it('should handle messages', async () => {
server.onMessage('test', (data) => ({ echo: data }));
const response = await client.request('test', { value: 42 });
expect(response.echo.value).toBe(42);
});
}); });
``` ```
