You Don't Know The ClassNames Library

You don't know the classNames library. You likely use the classNames library every day - but how well do you know it? You likely use the classNames library every day - but how well do you know it? Diving into React popularity, classNames performance. #reactjs #opensource #javascript #webdev #webdevelopment

Let me contradict the very title of this post from the start by saying that you probably know the classNames library very well.

This tiny open-source library, originally created by JedWatson, is nothing but a versatile string “concatenator.” Currently sitting at over 6M weekly downloads, it rose to popularity alongside React - the UI library that it’s most commonly used with.

As the name implies, it’s primarily meant for dealing with CSS classNames (very common in React and any other JSX-based UI framework), although you can use it for any kind of string concatenation.

The novelty of tiny NPM packages

But you most likely know it all. After all, given classNames and React popularity, there’s a high chance that you’ve used it before. But yeah, about this popularity.

It’s not uncommon to see tiny packages have insanely high download stats on NPM. You most likely have heard the stories of NPM packages with even less than 20 lines of code, breaking the internet because of the slightest change. Take is-promise for example - sitting at around 10M weekly downloads (mainly from its highly-popular dependents) - with its largest CJS version measuring 5 lines of code (LOCs):

module.exports = isPromise;
module.exports.default = isPromise;

function isPromise(obj) {
  return !!obj && (typeof obj === 'object' || typeof obj === 'function') && typeof obj.then === 'function';
}

React Testing Library: The Modern Way to Test React Components

Unit testing, and in our case, testing components, is a key element of any scalable and maintainable project. That truism is even more obvious now in the age of independent and shareable components. When sharing components between projects, testing serves as a way to both validate that a component behaves as expected and that it is independent and reusable (otherwise it would show to be very difficult to test).
