It seems less trivial than PadLeft.

as a joke i got a shirt with left-pad's source printed on it.

I was playing with String.prototype.padLeft earlier and boy that has weird semantics. For the padding length, strings are parsed. NaN is 0, Infinity throws an error, negative Infinity is 0, true is 1. Good ol’ JS!
Also not even test cases for such simple code.
It is a difficult to recommend a small package that is GPLv3, since your entire app would have to be licensed appropriately (since it runs in the same process).
For projects like Blender, where development is a self-reinforcing ecosystem I appreciate what the GPL does, here not so much.

i suspect the choice of GPLv3 was not well informed, given the nature of the code in question.
I have noticed that, in the wild, referencing window.localStorage at all will raise a security exception in some browsers. If this happens inside of a React hook, it will unmount everything up to the nearest componentDidCatch(). In practice, everything involving localStorage needs to make liberal use of try, catch blocks.
Seconded. localStorage can bite in bad ways, and the unmounting concerns are valid.
GPLV3 is an _interesting_ choice for a license for such a small amount of code (17 lines [0])

Is the react hook code so complicated that when it totals up to 17 lines of code[1], it needs to become a npm package? The code it self looks neat and clean - even more reason to just write your own hook.

Exactly, it can be treated as an example. It's an npm package so that I can reuse the code :)
It has been a fun journey implementing hooks in React. Let me know your thoughts on the code :)
Hey congrats! People will complain about the package being to small or trivial, but just keep on creating. We all start somewhere, and hooks are a fun thing to experiment with.
It's true that most folks probably would do their own implementation of this and the GPL license would be a non-starter for most projects, but if it suits your needs and you've learned something in the process, more power to you. :)

browser compatibility/other edge case handling would be one decent reason to utilize a package for otherwise straightforward implementations. The MDN docs have a helpful walkthrough for feature detecting localStorage that would make a useful addition to your library. https://developer.mozilla.org/en-US/docs/Web/API/Web_Storage...
Ooh, thanks. Must have a look
“Journey” is a bit of a stretch here, no? :)
This is a few lines of pretty trivial code

Can you please review the Show HN guidelines? I appreciate that you're not exactly flaming the OP here, but still, the idea is to respond more charitably to people's work. If you know more than others, find a constructive way to express that, such as by teaching them—and by extension, the rest of us—something related to what they've done so far.

This is a great point, and on a second reading my comment did come off as a little insensitive -- will leave it up to give others context and make this a teachable moment for all of us to improve the level of discourse :)
Maybe he meant more hooks, in general. For me that is true, hooks really are a very inspirational pattern
Getting the tooling up and running took awhile.
Must've been pretty hard to type `npx create-react-app my-app`
Please don't be a jerk on HN, regardless of how correct you are or feel you are.

Sorry Dang and Wolco.

I feel like the "it's a bit small for a package" comments have forgotten how js-land is going... For example, check out is-number: https://www.npmjs.com/package/is-number
