clsx VS usehooks-ts

clsx is a tiny utility for constructing className strings conditionally, I use it in conjunction with tailwind-merge which merges Tailwind CSS classes without style conflicts.

I am familiar with the library clsx although I have never used it personally. I don't often have the need for conditional classes and when I do it's usually an inline ternary expression in the style or className prop. Is that bad/good? Are there any other popular libraries other than clsx, or anti-patterns I should be aware of when doing conditional classes in React? Thanks fam

I use CLSX for all tailwind dynamic styles. Super simple, lightweight and now is almost part of every project I build haha

Then use something like clsx

For conditionally applying or removing classes, you should take a look at clsx.

clsx has better performance over the classnames package. That’s why it was created. Take a look at their benchmarks in the repo.

Hey, I'll have you know I have lots of fun using Tailwind with clsx =)

These depedencies provide unstyled accessible components from headless ui, icons from heroicons and common hooks with typescript support.

🏡 Local Storage - All score history, streaks, and user info is saved in Local Storage! Check out `useLocalStorage` by https://usehooks-ts.com/. A great resource and helpful when you want to quickly manage it like any other state.

We will store last search query string in local storage, thus I will summon useLocalStorage from usehooks-ts:

There are tons of examples of people building hooks for IntersectionObserver, they are probably a good deal more complex than what you want but you can learn a lot from how they do it and then simplify it to your needs, here is one: https://github.com/juliencrn/usehooks-ts/blob/master/src/useIntersectionObserver/useIntersectionObserver.ts

Take a look at Use hooks libraries for examples of code that you may want to have portability with (this is they typescript one because its the one I've used)

One of the simplest examples is "useToggle" which just sets a state variable to true or false. Not hard to write in a class component but it's still stuff that you may end up writing a lot.

A lot of similar ones are click and event handlers that need to be cleaned up after the component is unmounted.

useIsMounted is one I use a lot too to ensure I'm not trying to write state on an API callback once a component is unmounted.

You could add each of these to a class with an hoc and end up with withToggle(withIsMounted(withUseMediaEvent(MyComponent))) but that tends to be a bit of a mess.

This implementation of the useCopyToClipboard hook comes from the usehooks-ts library. It provides an easy way to copy text to the clipboard. Other React hooks libraries also have this hook which they implement differently: some rely on JavaScript libraries like copy-to-clipboard that run on document.execCommand() while others like this one depend on the clipboard API.
