What are some effective JSON API caching techniques?

There are several effective techniques for caching JSON APIs, such as using HTTP caching headers, implementing a reverse proxy, and utilizing in-memory data stores like Redis.

Can you explain how HTTP caching headers work?

HTTP caching headers like Cache-Control, ETag, and Last-Modified help control how responses are cached by browsers and intermediate caches, improving performance.

What is a reverse proxy and how does it help with caching?

A reverse proxy sits between clients and your server, caching responses to reduce load and speed up response times for repeated requests.

How does using Redis for caching compare to other methods?

Redis is an in-memory data store that provides fast access to cached data, making it ideal for high-performance applications compared to disk-based caching.

Are there any downsides to caching JSON APIs?

Yes, caching can lead to stale data if not managed properly, and it may add complexity to your application architecture.
