Top 5 React libraries which you must have

The styled components library (https://styled-components.com/) is one of my favorites. Not only helps with simple associations (const Styled = styled.div...) but also allows you to put JS code manipulation in CSS styles. It boosts our efficiency in Mobile Reality (themobilereality.com). It's easier also to reuse and work together on styles as we are component-oriented also in styles environment.

The other great library is zustand (https://github.com/pmndrs/zustand). State management has gone a long way since the beginning of Redux. From complex tools to simplicity. Zustand is one of the libraries where simple management is a goal. Not only simple but also tremendously performant.

React Hook Form. The moment when we in Mobile Reality discovered this library changed our development completely. Before that, we used redux-form. To be honest we weren't happy because of needed complex approach. React hook form did it well. We have switched to it immediately. Hook implementation resolve many issues which we had in previous projects. Recommend for sure!

React Query is a library that improves our development all the time. Instead of creating handlers for pending, fulfilled, and rejected states you can use hooks that give you all needed tools out of the box. You don't have to worry about missed loading phase for the end-user. What's more, you can benefit from cache synchronization and you can forget about re-fetching data. It will handle everything for you.

Finally, you can't forget about tests! React Testing Library is crucial to do it right and with ease. Good development includes best testing possible. With this library you can achieve it. It encourages performing component testing in a way that closely simulates how users would interact with your product. Highly recommend!
