Enterprise-grade webhook processing engine for Node.js applications with production-ready features:
- ✅ 7 Webhook Adapters - Stripe, GitHub, Discord, Shopify, PayPal, Twilio, SendGrid
- ✅ Signature Verification - Cryptographic validation for all providers
- ✅ Structured Logging - JSON logs with multiple outputs and rotation
- ✅ Security & Reliability - Rate limiting, circuit breakers, health monitoring
- ✅ CLI Tools - Development, testing, and monitoring utilities
- ✅ Multi-tenant Support - Handle multiple customers/environments
- ✅ Performance Monitoring - Real-time metrics and observability
- ✅ Error Recovery - Retry logic with exponential backoff
Most webhook implementations suffer from:
- 💥 Poor Error Handling - Silent failures in production
- 🔒 Security Gaps - Missing signature verification
- 📊 No Observability - Lack of monitoring and logging
- 🔁 No Retry Logic - Lost events due to temporary failures
- 🧪 Hard to Test - No development tools or replay capabilities
- 🏗️ Not Scalable - Can't handle multiple providers or high volume
Hook-Engine solves all these problems with a production-ready, enterprise-grade solution.
npm install hook-engine
# or
yarn add hook-engine
# or
pnpm add hook-engine
Global CLI installation:
npm install -g hook-engine
import express from 'express';
import { receiveWebhook } from 'hook-engine';
const app = express();
// Raw body parser for signature verification
app.use('/webhooks', express.raw({ type: 'application/json' }));
app.post('/webhooks/stripe', async (req, res) => {
try {
const event = await receiveWebhook(req, {
source: 'stripe',
secret: process.env.STRIPE_WEBHOOK_SECRET
});
console.log(`✅ Received ${event.type}:`, event.id);
// Your business logic here
switch (event.type) {
case 'invoice.payment_succeeded':
console.log('💰 Payment succeeded!');
break;
case 'customer.subscription.created':
console.log('🎉 New subscription!');
break;
}
res.status(200).json({ success: true });
} catch (error) {
console.error('❌ Webhook failed:', error.message);
res.status(400).json({ error: 'Webhook processing failed' });
}
});
app.listen(3000, () => {
console.log('🚀 Webhook server running on port 3000');
});

// Stripe
const stripeEvent = await receiveWebhook(req, {
source: 'stripe',
secret: 'whsec_...'
});
// GitHub
const githubEvent = await receiveWebhook(req, {
source: 'github',
secret: 'github_webhook_secret'
});
// Shopify
const shopifyEvent = await receiveWebhook(req, {
source: 'shopify',
secret: 'shopify_webhook_secret'
});
Handle webhooks from multiple providers in a single application:
import { receiveWebhook, adapters } from 'hook-engine';
const webhookConfigs = {
stripe: { source: 'stripe', secret: process.env.STRIPE_SECRET },
github: { source: 'github', secret: process.env.GITHUB_SECRET },
shopify: { source: 'shopify', secret: process.env.SHOPIFY_SECRET }
};
app.post('/webhooks/:provider', async (req, res) => {
const provider = req.params.provider;
const config = webhookConfigs[provider];
if (!config) {
return res.status(400).json({
error: `Unsupported provider: ${provider}`,
supportedProviders: Object.keys(webhookConfigs)
});
}
const event = await receiveWebhook(req, config);
// Route to appropriate handler
switch (provider) {
case 'stripe':
await handleStripeEvent(event);
break;
case 'github':
await handleGitHubEvent(event);
break;
case 'shopify':
await handleShopifyEvent(event);
break;
}
res.status(200).json({ success: true, provider, eventId: event.id });
});
Enterprise-grade logging with JSON output, multiple transports, and rich metadata:
import { StructuredLogger } from 'hook-engine';
const logger = new StructuredLogger({
level: 'info',
format: 'json',
outputs: [
{
type: 'console',
config: { colorize: true }
},
{
type: 'file',
config: {
filename: './logs/webhooks.log'
}
}
],
enableColors: true,
enableTimestamps: true,
enableStackTrace: true,
maxFileSize: 10 * 1024 * 1024, // 10MB
maxFiles: 5,
rotateDaily: true
});
// Webhook-specific logging
logger.webhook({
level: 'info',
source: 'stripe',
operation: 'webhook_processed',
duration: 150,
status: 'success',
metadata: {
eventType: 'invoice.payment_succeeded',
eventId: 'evt_123',
requestId: 'req_456'
}
});
// Performance logging
logger.performance({
level: 'info',
operation: 'payment_processing',
duration: 200,
metrics: {
memoryUsage: process.memoryUsage().heapUsed,
requestCount: 1
},
metadata: { requestId: 'req_456' }
});
// Security logging
logger.security({
level: 'warn',
securityEvent: 'invalid_signature',
source: '192.168.1.100',
severity: 'medium',
details: {
ip: '192.168.1.100',
userAgent: 'curl/7.68.0',
endpoint: '/webhooks/stripe',
reason: 'Invalid webhook signature'
},
metadata: { requestId: 'req_456' }
});
Built-in security and reliability features for production environments:
import { SecurityManager, ReliabilityManager } from 'hook-engine';
// Security features
const securityManager = new SecurityManager({
rateLimiting: {
windowMs: 15 * 60 * 1000, // 15 minutes
maxRequests: 100
},
ipFiltering: {
allowlist: ['192.168.1.0/24'],
denylist: ['10.0.0.0/8']
},
signatureValidation: {
enforceSignatures: true,
allowedClockSkew: 300 // 5 minutes
}
});
// Reliability features
const reliabilityManager = new ReliabilityManager({
circuitBreaker: {
failureThreshold: 5,
resetTimeout: 60000
},
healthChecks: {
interval: 30000,
timeout: 5000
},
gracefulShutdown: {
timeout: 30000
}
});
// Apply middleware
app.use('/webhooks', securityManager.middleware());
app.use('/webhooks', reliabilityManager.middleware());

Complete e-commerce platform handling payments, orders, deployments, and email events:
import express from 'express';
import {
receiveWebhook,
StructuredLogger,
SecurityManager,
ReliabilityManager
} from 'hook-engine';
const app = express();
// Setup structured logging
const logger = new StructuredLogger({
level: 'info',
format: 'json',
outputs: [
{ type: 'console', config: { colorize: true } },
{ type: 'file', config: { filename: './logs/ecommerce.log' } }
]
});
// Business services
class EcommerceServices {
static async processPayment(event, logger) {
logger.info('Processing payment event', {
operation: 'payment_processing',
eventType: event.type,
eventId: event.id
});
switch (event.type) {
case 'invoice.payment_succeeded':
await this.handlePaymentSuccess(event, logger);
break;
case 'invoice.payment_failed':
await this.handlePaymentFailure(event, logger);
break;
}
}
static async processOrder(event, logger) {
logger.info('Processing order event', {
operation: 'order_processing',
eventType: event.type,
eventId: event.id
});
switch (event.type) {
case 'orders/create':
await this.handleNewOrder(event, logger);
break;
case 'orders/paid':
await this.handleOrderPaid(event, logger);
break;
}
}
}
// Webhook handler with full feature demonstration
app.post('/webhooks/:provider', async (req, res) => {
const provider = req.params.provider;
const startTime = Date.now();
try {
const config = webhookConfigs[provider];
const event = await receiveWebhook(req, config);
// Route to appropriate service
switch (provider) {
case 'stripe':
await EcommerceServices.processPayment(event, logger);
break;
case 'shopify':
await EcommerceServices.processOrder(event, logger);
break;
}
const duration = Date.now() - startTime;
logger.webhook({
level: 'info',
source: provider,
operation: 'webhook_processed',
duration,
status: 'success',
metadata: { eventType: event.type, eventId: event.id }
});
res.status(200).json({
success: true,
provider,
eventId: event.id,
processingTime: `${duration}ms`
});
} catch (error) {
logger.error('Webhook processing failed', error);
res.status(400).json({ error: 'Webhook processing failed' });
}
});
Handle webhooks for multiple customers or environments:
import { MultiTenantManager } from 'hook-engine';
const tenantManager = new MultiTenantManager({
tenantResolver: (req) => {
// Extract tenant from subdomain, header, or path
return req.headers['x-tenant-id'] || 'default';
},
configProvider: async (tenantId) => {
// Load tenant-specific configuration
return await loadTenantConfig(tenantId);
}
});
app.use('/webhooks', tenantManager.middleware());
Advanced event processing with filtering and routing:
import { EventProcessor } from 'hook-engine';
const processor = new EventProcessor({
filters: [
{
eventType: 'push',
condition: (event) => event.payload.ref === 'refs/heads/main'
}
],
routes: [
{
condition: (event) => event.type === 'invoice.payment_succeeded',
destination: 'payment-service'
},
{
condition: (event) => event.type.startsWith('orders/'),
destination: 'order-service'
}
]
});
Process multiple events efficiently:
import { BatchProcessor } from 'hook-engine';
const batchProcessor = new BatchProcessor({
batchSize: 10,
flushInterval: 5000, // 5 seconds
processor: async (events) => {
console.log(`Processing batch of ${events.length} events`);
await processBatch(events);
}
});
