What are the cache policies in Apollo Client?

Apollo Client offers several cache policies, including 'cache-first', 'network-only', and 'cache-and-network'. Each policy determines how the client interacts with the cache and the network.

Can you explain the 'cache-first' policy?

Sure! The 'cache-first' policy checks the cache for data first. If the data is available, it returns it immediately; if not, it fetches from the network.

What about the 'network-only' policy?

The 'network-only' policy bypasses the cache entirely and always fetches data from the network, ensuring you get the most up-to-date information.

Are there any scenarios where 'cache-and-network' is useful?

Yes, 'cache-and-network' is useful when you want to show cached data immediately while also fetching the latest data from the network to update the UI.
