Type Alias ConfigurationExtended<Data, Error, Fn>

Type Declaration

• Optionalwhen?: boolean | (() => boolean)

  Conditional fetching as option

  Moving this to an option allows us to keep the endpoints typed dictionary, e.g. we can write:

  const { data, mutate } = myApi.use("User/{id}",
   { params: { id: aVariableMaybeContainingAnId || "" }, },
   { when: !!aVariableMaybeContainingAnId }
  );
  
  // we still have typed `data`, `mutate`
  Copy
