Request is fired on mount even when key is the same

[pke]

Is this the standard behaviour that all swr hooks refetch the data on mount even if the key hasn't changed? What is the reasoning for that? I have hook that downloads large files and I have the files checksum as one of the cache key and even when the checksum stays the same between mounts/rerenders, the fetch method of the swr hook is still called.

When I set "revalidateOnMount" to false then the fetch function is never called.

Where is my misunderstanding?

Hi, you don't say what behaviour you would prefer here.

That it is not refetched if the key hasn't changed
