browser support

[ronag]

This is just a fun thought that I don't personally plan to spend much time on.

It should be in theory possible to run undici in the browser (especially the fetch parts) if one creates a BrowserClient implementation based on e.g. XMLHTTPRequest. That way we could in theory even act as an alternative to e.g. https://github.com/github/fetch fetch polyfill.

We have implemented some of the web stuff from the spec and there a clear TODOs (examples) with references to spec for the missing parts. There are a few node specific stuff we make use of (e.g. Buffer) but those should be somewhat trivial to either replace or polyfill.

@JakeChampion just a friendly ping in case there is any potential room for collaboration with https://github.com/github/fetch.

Sounds fun but also pointless, XMLHttpRequest don't have any good streaming support

also you would be importing a browserified version of node:http that includes buffer, readable-stream and many other small sub packages like inherit. that alone is some few 170kb of code the amount code would be large

pretty much all browser ships fetch now days. so what would be the point?
