stateful fetch client #435

Describe the feature

ofetch/$fetch same as native fetch is stateless by-design. This has safety advantages when ofetch is deeply integrated into tools such as Nitro and Nuxt and prevents global side effects and potential header leaks.

However, there are also good use cases of having stateful fetch instances:

Sharable headers
Cookie jar (#382)
Global interceptors such as auth

I think $fetch.withState() could be useful.

It's very good idea especially useful for testing API's

Hi @pi0 What's the difference between this and ofetch.create ?

pi0 commented 1 day ago

@guyaumetremblay ofetch.create creates instance with immutable defaults. this version has mutable state (and most importantly working cookies, just like a browser tab)
