Async functions lack cancelability. We can use generator functions for mimicking cancelable async functions. I created a library fo...

This is really cool! Is this published anywhere as a package?
Also you seem to have an error in your last example, you are doing
await fetchinstead ofyield fetchThanks for this piece of code, really helpful!
Thanks 🙏 I fixed it!
I have no package published, currently I am just copy pasting it into my projects.
Please do publish it
Finally got around building the package with tests: github.com/n1ru4l/use-async-effect
Thank you
Very useful! Busy to transfer a huge app from angularjs to react and I have implemented your strategy in our fetch calls. Thanks for sharing practical info!
I have also added "sleep" in the API of the server sering data to the app (c# web.api) to test all kind of scenarios and everything was working exactly as expected ;-)
Looks really nice!
Do you know if there is a way to extend this so that it could be executed on demand? What I'm after is a basic save functionality.
What I have been doing so far is just having a callback which calls an async function. The callback is then called from the save buttons onClick handler. This of course doesn't support cleaning up so if the component gets unmounted before saving request has finished it might call setState on an unmounted component
I thought about creating useAsyncCallback. Shouldn‘t be to hard to implement!
[Already Solved] React Hook Warnings for async function in useEffect: useEffect function must return a cleanup function or nothing
completely different solutions and none of them show case aborting effects upon component unmount as well as handling effect re-runs with potential race conditions :)
Superb dissection of this issue and work!
Really nice of you to share this! I will definitely use it in dashboard I'm working on :)
Thank you
