What are the best practices for caching in Express.js?

The best practices for caching in Express.js include using middleware like apicache, setting appropriate cache headers, and implementing cache invalidation strategies.

Can you explain how to use apicache?

Sure! To use apicache, first install it via npm. Then, you can use it as middleware in your Express routes to cache responses.

What are cache headers, and why are they important?

Cache headers control how responses are cached by browsers and proxies. They help improve performance and reduce server load.

How do I implement cache invalidation?

Cache invalidation can be implemented by setting expiration times for cached data or by manually clearing the cache when data changes.
