How do I implement caching in APIs?

Implementing caching in APIs can significantly improve performance. You can use techniques like in-memory caching, HTTP caching, or distributed caching. What specific type of API are you working with?

I'm working with a RESTful API. What caching strategies would you recommend?

For a RESTful API, consider using HTTP caching headers like Cache-Control and ETag. You can also implement server-side caching with tools like Redis or Memcached.

How do I set up Redis for caching?

To set up Redis, first install it on your server. Then, use a Redis client library in your API code to store and retrieve cached data. Would you like a code example?

Yes, please provide a code example for using Redis in a Node.js API.
