Can patch-package detect content changes in package.json? Let's say I changed a dependency version？

Yes with the method above, or by manually editing the diff. It probably won't help you though, e.g. if you're trying to change peer deps to stop getting warnings/errors with npm update/install.

I believe npm uses its online registry to resolve peerDeps. You can stop warnings with npm install (not update) by changing the peerDependencies for the package in question in your own package-lock.json.
