Provide example usage with mutations in Tanstack query

[onyedikachi23]

I'm really interested in understanding the need for this project, as optimistic updates have never been a problem for me using Tanstack Query.

The README only gave an example implementation in ElectricSQL. In which I was really expecting an example with actual Tanstack stuffs like Tanstack Query. In most cases, I only happen to perform optimistic updates during mutations ( with useMutation). So please, give an example.

The mutations are done in the mutationFn. The example in the readme show doing fetch calls to a backend API. There's also a full example in the repo you can look at. This isn't meant to be used with Tanstack/query, it's rather a replacement for when you're building with a sync engine

The goal here is to make optimistic updates very easy -- not everyone will need it but if you're building an app with extensive optimistic updates and lots of backend changes (especially unpredictable ones or in multi-user or agentic apps) then this will be really helpful.

I reviewed the full React example and understand it now.

I posted this discussion because someone on X mentioned rewriting their optimistic updates in the useMutation hook to use this library when it's ready.

I was looking for an example and a compelling reason to migrate from the already simple useMutation setup.

Which discussion btw?
