8. makeMonitoredFetch

makeMonitoredFetch

makeMonitoredFetch wraps fetch functions and invokes onFetching while it is fetching, onSuccess when a fetch has successfully resolved and onError if the fetch rejects. If the fetch is not enabled then fetch is not executed.

makeMonitoredFetch can be used to display a loading indicator when a fetch is inflight or in conjunction with useNetworkMode to disable a fetch when there is no network connectivity.

Options

makeMonitoredFetch has the following options available:

Required

• fetchFn: any function that returns a Promise

Optional

• onFetching: invoked with true when a fetch is inflight and false when a fetch has settled

• onSuccess: invoked with the result of the fetch and the arguments to it upon resolving successfully

• onError: invoked with the resulting error and the arguments to fetch upon rejecting

• enabled: if false, the fetch will be disabled. Defaults to true
