Adding middlewares on the server

Catalyst offers a flexible approach to defining server-side code, granting you greater control and customization over server operations.

Middleware Best Practices

Order Matters

Middleware executes in the order they're added. Add security middleware first.

Error Handling

Always call next() or send a response to prevent hanging requests.

Performance

Keep middleware lightweight and avoid blocking operations.

Middleware Examples

This example demonstrates how to implement custom middleware in Catalyst applications.

Request Logging

Log all incoming requests for debugging and monitoring.

Benefits

• Debug requests
• Monitor performance
• Track errors

Implementation

app.use((req, res, next) => {
  console.log(`${req.method} ${req.url} - ${new Date().toISOString()}`)
  next()
})
