`$fetch` type-safety for calling other Nitro endpoints

[manniL]

Describe the feature

Hey! It might be a far fetch, but sometimes, one nitro endpoint calls another one via $fetch (e.g. a Nuxt server route calling an API endpoint). Would it be possible to achieve $fetch type-support here too?

Opening in this repo instead of the nuxt framework repo because it could be supported for all nitro setups.

Additional information

• [ ] Would you be willing to help implement this feature?

[danielroe]

This should work already. Would you give an example of it not working?

[manniL]

Yes, sure! StackBlitz attached, tested locally.

It seems to be working in latest nitro
