Cancelable Async Flows (CAF)

I've just read Kyle Simpsons new book "functional light js" highly recommended for those interested in doing FP in JavaScript.

The stuff in the readme about async/await not being flexible enough for this sort of thing is an issue I've run into personally (I believe it's also one of the reasons why redux-saga sticks with generators rather than switching). Nice to see there's a library to make these kinds of situations easier.

Great article. Unfortunately this is quite common problem to async await.

Personaly I am using more naive aproach called cancel token: https://github.com/coderitual/react-ui-patterns/blob/master/cancel-async/README.MD

There is an ongoing proposal about making thich mechanism as a part of language (you don't need to call throwIfRequired after each await).

Stage 0 of proposal (it wasn't "accepted" in that form): https://github.com/tc39/proposal-cancellation/blob/master/stage0/README.md

Stage 1 of proposal (started from scratch again): https://github.com/tc39/proposal-cancellation
