What are Apollo Client fetch policies?

What are Apollo Client fetch policies?

Apollo Client fetch policies determine how the client interacts with the cache and the server when fetching data.

Can you explain the different fetch policies available?

Sure! The main fetch policies are 'cache-first', 'network-only', 'cache-only', and 'no-cache'. Each has its own use case.

When should I use 'cache-first'?

Use 'cache-first' when you want to prioritize cached data for performance, falling back to the network only if the data isn't available.

What about 'network-only'? When is that useful?

'Network-only' is useful when you always want the most up-to-date data from the server, ignoring the cache.
