Fetch policy: cache-first, cache-and-network and network-only #317

ArnaudWeyts · 2020-04-28T15:04:48Z

Added

A new option: fetchPolicy
- cache-first: will look at the cache and return the cached value or send a request
- cache-and-network: returns cached data immediately, but also sends a request to refresh it
- network-only (previously ignoreCache = true): ignores the cache and always sends network requests

The default value is cache-first unless ignoreCache is set to true, in which case fetchPolicy will default to network-only

this is a remnant of the old queries implementation

it will replace the ignoreCache option in the next minor version

this way we preserve backwards compatibility, this will be removed in the next minor version bump

cache-first and cache-and-network will both set the initial state from the global store, otherwise the initial state is empty

cache-first will not send a request, cache-and-network will set the cached state, and send a request, network-only will not take the cache into account

the data will already be set by the initial state
