How can I optimize middleware in my Express application?

How can I optimize middleware in my Express application?

To optimize middleware in Express, consider the order of middleware, use built-in middleware, and avoid heavy computations.

What do you mean by the order of middleware?

The order of middleware matters because Express processes them in the sequence they are defined. Place frequently used middleware first.

Are there any built-in middleware I should use?

Yes, use built-in middleware like express.json() for parsing JSON requests and express.static() for serving static files.

How can I avoid heavy computations in middleware?

Offload heavy computations to background jobs or use caching strategies to minimize processing time in middleware.
