React Hooks is the new hotness in the React world. I'm writing steadily more and more of them and I thought it would be useful to have a cheatsheet...

Thanks man. Are you sure about naming with ‘use’?
I don’t think it’s mandatory, you can create any named function as hooks. Probably this might be the recommended way same as how HOC are made with ‘with’ prefix
The React team provide an ESLint plugin that prevents incorrect usage of hooks, but you must name them with

Yeah I got it, thanks for the link
It's a suggestion by the React team - a best practice to make the intent clear.
Interesting. I guess I haven't tested it but it's straight from their docs:
Hi Antonin, Thanks for writing this. I think it's very useful.
I have one comment regarding your useUser hook. I think it's important to "cancel" the request before the component unmounts to avoid memory leaks.
I wrote about it a few days ago. You might want to have a look:

Cheers!
In this case there's no memory leak though.
It's simply a warning as updating the state will effectively do nothing after the component has been unmounted.
Ah. I see your point. I suppose the dangling reference to the component gets garbage-collected after the promise resolves and state is updated?
Is it possible to use a custom hook in place of something like a render prop or a higher order component?
Yes, that was one of the use-cases they had in mind when creating hooks.
Awesome. I now I need to practice and figure out how to do that.
Nice article, I like the
useReducercode sandbox example, pretty straight forward. I follow a similar template in my "Guide to Learning React Hooks article", you should check it out.Thanks for an article.
Another great place to wrap a head around hooks is Dan's blog.
Dan's blog is awesome.
