javascript - What is the difference between isomorphic-fetch and fetch?

Question

I've seen two different fetch here:

• https://github.com/github/fetch

• https://github.com/matthew-andrews/isomorphic-fetch

Can someone tell me the difference between the two?

PS: I've read the README.md but I still didn't get the difference. Last time I checked, Isomorphic means it has similar form or relation. It still doesn't make sense to me.

Answer 1

FETCH is polyfill for browsers which don't have fetch function (caniuse.com/#search=fetch). It will add fetch function to your browser window object.

While isomorphic-fetch is implementation of fetch for both node.js and browser, built on top of fetch polyfill.
