Feature Request: dedup

[tlrib]

Hey! Recently found this project and I've been loving it.

I've used wretch before and one thing I'm missing is the middlewares - particularly the dedup middleware.

Given the flexibility of up-fetch, I understand that this is something I could implement myself but I feel like it could be a good addition to the library, for a cleaner integration and so consumers don't have to "reinvent the wheel".

Let me know your thoughts

Best regards,
Tiago

Feels a bit out of scope for the core lib, more like something for a higher-level tool (e.g. TanStack Query).

Might be missing context though, can you share your use case?

For client side usage, libraries like Tanstack Query solve it 100%.
My current use case is in server side usage were I just want to reuse in-flight requests (and don't want to reach to a more complicated solution like caching).

I understand the vision of keeping the core library tight, that's a decision I respect. Maybe an option would be to create a "recipe" to show how it could be done?
