How can I improve the performance of middleware in Express.js?

To improve middleware performance in Express.js, consider minimizing the number of middleware functions, using asynchronous functions, and caching responses.

What are some common performance bottlenecks in Express middleware?

Common bottlenecks include synchronous operations, excessive logging, and heavy computations within middleware.

Can you suggest some best practices for writing efficient middleware?

Sure! Use lightweight libraries, avoid blocking code, and ensure middleware is only applied to necessary routes.

How does middleware order affect performance?

Middleware order is crucial; placing heavier middleware later can prevent unnecessary processing for certain requests.
