What are some effective caching strategies for JSON fetch requests?

There are several effective caching strategies for JSON fetch requests, including: 1. In-memory caching: Store responses in memory for quick access. 2. Local storage: Use browser local storage to persist data across sessions. 3. Service workers: Implement service workers to cache responses and serve them offline. 4. Cache-Control headers: Utilize HTTP headers to control caching behavior.

Can you explain how to implement in-memory caching?

Sure! In-memory caching can be implemented using a simple JavaScript object or a Map. When you fetch data, first check if it's in the cache. If it is, return the cached data; if not, fetch it from the server and store it in the cache for future requests.

What are the pros and cons of using local storage for caching?

Pros of local storage include persistence across sessions and easy access. However, cons include limited storage space and potential security risks if sensitive data is stored.

How do service workers improve caching?

Service workers act as a proxy between your web app and the network. They can intercept network requests and serve cached responses, allowing for offline access and faster load times.
