How can I optimize the performance of my Express middleware?

To optimize your Express middleware, consider minimizing synchronous operations, using caching, and reducing the number of middleware functions.

What are some common performance bottlenecks in middleware?

Common bottlenecks include heavy computations, database calls, and excessive logging. Profiling your middleware can help identify these.

Can you suggest some caching strategies?

You can use in-memory caching with Redis or implement HTTP caching headers to reduce load times and improve response speed.

How do I measure the performance of my middleware?

You can use tools like Node.js built-in profiler, or third-party libraries like express-status-monitor to track performance metrics.
