Does Nitro polyfill Node APIs like fetch?

[sannajammeh]

Hi! We are building apps with Nitro and run all systems on Node v20 and v21. These have builtin support for fetch via Undici. Will Nitro polyfill this with node-fetch or similar? There is very little information about the internals of Nitro on the docs page.

I am asking as the native Node.js fetch has support for Undici's CacheStorage API allowing us to cache things like JWKs from authorization servers at the runtime level.

Nitro uses https://github.com/unjs/ofetch, which will use globalThis.fetch when available.
