Automatically revalidate after any successful fetch() mutation

[colinclerk]

Remix has a feature that automatically re-runs (revalidates) "loaders" after any "actions" (mutations).

That's what enables the automatic refresh after form submissions:

This got me thinking - can useSWR do the same by listening for 200s on POST/PUT/PATCH/DELETE requests and automatically triggering revalidation after they run?

(It's worth mentioning that there's no obvious "best" implementation for this, since Javascript doesn't have a way to listen to requests. Two approaches are: 1) override window.fetch, and 2) ask developers to import a fetch from swr)
