The problem with current createEffect typescript typings is that
FN extends () => infer Done
condition satisfies zero-or-one-arity effect handlers. Handler like(x?: TYPE) => any
will produceEffect<void,...>
. New test suite with updated snapshots displays these errors.You may see new typings proposal partially improving current situation. I added some comments to explain why it was difficult to deal with type
any
.The last commit contains finally updated snapshots to demonstrate how proposed typings work.
