There was a problem hiding this comment.
Yeah this is expected, I'm okay with the eslint ignore mark here. 👍

This is the last PR to fix all
react-hooks/exhaustive-depswarnings.The PR fixes the warnings in
useSWR, which adds some deps formemoizedStateand disables the rule forrevalidate.For
memoizedState, I've added all deps in the deps array.boundMutateis an immutable function, so we can omit it, but I've added it to the deps array to enablereact-hooks/exhaustive-depsrule. It's an immutable function, so it shouldn't be a problem.For
revalidate, I've disabled thereact-hooks/exhaustive-depsrule becausefnandconfigare defined as the arguments ofuseSWRcall, which means those values would be changed every time.I could add
eventsCallback,fnArgs,keyErr, andkeyValidatinginto the deps array. It should be safe because they only depend onkeythat is already in the deps array.But it makes tests flakier because current tests depends on JavaScript timer naively. If I added meaning-less values in the deps array for
revalidate, tests would be failed frequently. So I didn't add them into the deps array.I'll investigate the way to fix flaky tests.
