In no particular order, here are the ten libraries that I think every React dev should at least know about.

1. MobX

This is a library for managing state in JavaScript applications. It helps you keep track of changes to your data and automatically updates your user interface when those changes occur.

Think of it like a magic assistant sitting in your code and watching everything happening. Whenever something changes, it waves its wand and updates your app accordingly. You don’t have to worry about manually updating the interface or keeping track of all the different pieces of data. MobX takes care of it for you.

This makes it much easier to build complex applications. Because you can focus on writing the code that makes your app work. Rather than worrying about the plumbing that connects everything. With MobX, you can create reactive, responsive apps that feel snappy and fast.Eeven when dealing with large amounts of data.

2. MUI Core

Also known as Material-UI, this is a popular open-source UI component library for React based on Google’s Material Design principles. Providing pre-built and customizable UI components such as buttons, forms, icons, typography, and more. Developers can use these to quickly build modern and visually appealing web applications.

It follows a component-based architecture, allowing developers to easily create reusable and composable UI components. It also provides theming support, allowing developers to customize the look and feel of their applications. This is done by defining their colour palette, typography, and other design elements.

MUI Core is widely used in the React community and has a large and active community of contributors. It is continuously updated and improved, with new features and components regularly added. Licensed under the MIT License, making it free to use and modify in commercial and non-commercial projects.

3. Styled Components

Styled Components

A popular CSS-in-JS library for React that allows developers to write CSS code inside their React components. It provides a way to style components more modularly and reusable way. The styles are encapsulated within the component. Therefore they don’t affect other components of the application.

This library allows developers to define styles as JavaScript functions or tagged template literals. These styles are then applied to the corresponding components using a higher-order component (HOC) or a styled component factory function. This makes it easy to create responsive and dynamic styles based on props or state.

It also supports server-side rendering, theming, and automatic vendor prefixing. Making it a versatile and powerful tool for styling React components.

One of the advantages of using this is that it allows developers to write CSS in a more maintainable way. By keeping styling close to the components they style, it becomes easier to reason about how style changes will affect the component and its children. Additionally, this library allows developers to use all the power of JavaScript to create dynamic and complex styles. This makes it a very flexible and powerful tool for building modern web applications.

Could you think of how styled components could be used in our Card component?

4. react-icons

React Icons is a popular open-source library that provides a set of customizable icons for use in React applications. It offers a wide range of icons from popular icon sets such as FontAwesome, Material Design, and Ionicons, as well as custom-designed icons.

React Icons provides a simple and flexible API that allows developers to add icons to their components easily. It supports multiple sizes, colours, and styles for each icon and provides different ways to import and use icons depending on the developer’s preferences.

Some of the advantages of using React Icons include the following:

Summing up, React Icons is a great tool for developers who need to add icons to their React applications in a flexible and customizable way.

5. react-query

Create React App (CRA) is an open-source tool created by Facebook for setting up a modern React application with zero build configuration. It provides a simple and streamlined way to create and manage a new React project, allowing developers to focus on building their applications instead of worrying about tooling and configuration.

Create React App sets up a development environment for React that includes many of the commonly-used tools and technologies, such as:

Create React App also provides several configuration options, allowing developers to customize their development environment to suit their needs. It supports CSS modules, environment variables, code splitting, and more.

Overall, Create React App is a powerful tool that makes it easy to set up a new React project with minimal configuration, allowing developers to focus on building their applications instead of managing tooling and configuration.

8. react-motion

React Motion is a popular open-source library for building animated user interfaces in React applications. It provides a simple and intuitive API for creating complex animations and interactions, allowing developers to create fluid and engaging user experiences.

React Motion is based on the principles of physics-based animation, which means that a set of parameters such as velocity, acceleration, and damping drives animations. This approach allows for more natural and realistic animations that respond to user input and change over time.

Some of the key features of React Motion include:

Overall, React Motion is a powerful tool for building animated user interfaces in React applications, allowing developers to create engaging and interactive experiences that respond to user input and change over time.

9. Enzyme

Enzyme is a popular open-source JavaScript testing utility created by Airbnb for testing React components. It provides a set of intuitive and flexible APIs for testing React components’ behaviour and state changes, making it easy to write comprehensive and reliable tests for React applications.

Enzyme offers several features that make it a powerful tool for testing React components, including:

Enzyme is a powerful testing utility that makes writing comprehensive and reliable tests for React components easy. Its intuitive and flexible API, along with its support for shallow rendering, full DOM rendering, and snapshot testing makes it a popular choice among developers for testing React applications.

10. Next.js
