FetchPolicy enum

FetchPolicy determines where the client may return a result from.

  • cacheFirst: return result from cache. Only fetch from network if cached result is not available.
  • cacheAndNetwork: return result from cache first (if it exists), then return network result once it's available.
  • cacheOnly: return result from cache if available, fail otherwise.
  • noCache: return result from network, fail if network call doesn't succeed, don't save to cache.
  • networkOnly: return result from network, fail if network call doesn't succeed, save to cache.

The default fetchPolicy for each method are:

These can be overriden at client construction time by passing a DefaultPolicies instance to defaultPolicies.
