Ky has a stream API as far as I am concerned. The API is a bit different since it uses WHATWG streams, and I suppose we don't have got-style shortcuts for it, but it's very easy to use.

Can't we also say Ky has Electron support, at least via ky-universal? Maybe that's not fair since it uses node-fetch to do so. 🤷‍♂️

For progress events, at the moment we have download progress, but not upload progress.

But node-fetch does not support electron, electron-fetch does, right?

[sholladay]

I guess I assumed "Electron support" meant that it has to work in both main and renderer processes, which ky-universal should be able to, but node-fetch couldn't on its own. Or am I misunderstanding?

I guess "Electron support" mean support Electron's net module.

node-fetch use http module in nodejs.
