This content originally appeared on DEV Community and was authored by Alex

React has become one of the most popular libraries for building user interfaces, and it's continuously evolving. As we move into 2024, understanding the latest roadmap for learning React is crucial for developers looking to stay ahead of the curve. This guide will walk you through the essential topics and concepts you need to master to become proficient in React. We'll provide links to official documentation and resources for further reading and practice.

1. CLI Tools

Vite

Vite is a next-generation front-end tool that allows for fast and optimized development. It serves as an excellent alternative to create-react-app for setting up your React projects. Vite provides a lightning-fast development server and a highly efficient build process.

Create React App

Create React App is the official React CLI tool for setting up a new React project. It's an excellent starting point for beginners as it abstracts away the configuration details, allowing you to focus on writing your application.

2. Components

Class Components

Although functional components are now the preferred way of writing components in React, understanding class components is still beneficial, especially for maintaining legacy codebases.

Functional Components

Functional components have become the standard for writing React components due to their simplicity and the introduction of Hooks, which allow for state and lifecycle management within these components.

Component Life Cycle

Understanding the component lifecycle is essential for managing the state and side effects in your application. It helps in optimizing performance and ensuring proper resource management.

Lists and Keys

Managing lists and keys correctly is crucial for performance optimization in React. Learn more about lists and keys.

Render Props

Render props is a pattern for sharing code between React components using a prop whose value is a function.

Refs

Refs provide a way to access DOM nodes or React elements created in the render method.

Events

Handling events in React is different from handling DOM events in plain HTML, primarily due to the virtual DOM.

High Order Components

High Order Components (HOCs) are a pattern in React for reusing component logic.

3. State Management

Recoil

Recoil provides a way to manage the global state in React applications. It's an alternative to other state management solutions and integrates seamlessly with the React ecosystem.

MobX

MobX is a simple, scalable state management solution that uses observables to track state changes.

Redux / Toolkit

Redux is one of the most popular state management libraries for React. The Redux Toolkit simplifies the process of setting up and using Redux in your projects.

Zustand

Zustand is a small, fast, and scalable state management solution that provides an intuitive API for managing state in React applications.

Context

The Context API is built into React and allows you to share state across your application without passing props down manually through every level of the component tree.

4. Routers

React Router

React Router is the standard routing library for React. It allows you to handle navigation in your single-page application effectively.

Reach Router

Reach Router aims to provide accessible routing for React applications with a focus on accessibility and simplicity.

5. Hooks

Basic Hooks

• useState: useState is a Hook that lets you add state to functional components.
• useEffect: useEffect lets you perform side effects in function components.

Writing Custom Hooks

Custom Hooks allow you to extract component logic into reusable functions.

Common Hooks

• useCallback: useCallback returns a memoized callback.
• useMemo: useMemo returns a memoized value.
• useRef: useRef returns a mutable ref object.
• useReducer: useReducer is usually preferable to useState when you have complex state logic.
• useContext: useContext lets you subscribe to React context without introducing nesting.

6. Styling

Emotion

Emotion is a performant and flexible CSS-in-JS library.

Styled Components

Styled Components allows you to write plain CSS in your JavaScript.

CSS Modules

CSS Modules are a popular way to write scoped CSS.

TailwindCSS

TailwindCSS is a utility-first CSS framework that allows you to build modern websites without leaving your HTML.

Material UI

Material UI is a popular React UI framework that implements Google's Material Design.

Mantine

Mantine is a modern React component library with a focus on accessibility and usability.

Chakra UI

Chakra UI is a simple, modular, and accessible component library that provides the building blocks you need to build your React applications.

7. API Calls

REST

REST is the standard for building APIs. Learn more about REST.

SWR

SWR is a React Hook for data fetching that makes it easy to fetch, cache, and revalidate data at the component level.

react-query

react-query simplifies data fetching and state management in your React applications.

Axios

Axios is a promise-based HTTP client for the browser and Node.js.

superagent

superagent is a small progressive client-side HTTP request library.

rtk-query

rtk-query is part of Redux Toolkit and provides powerful data fetching and caching capabilities.

GraphQL

GraphQL is a query language for your API, and a runtime for executing those queries by using a type system you define for your data.

Apollo

Apollo is a comprehensive state management library for JavaScript that enables you to manage both local and remote data with GraphQL.

Relay

Relay is a JavaScript framework for building data-driven React applications.

Urql

Urql is a highly customizable and versatile GraphQL client for React.

8. Testing

Jest

Jest is a delightful JavaScript testing framework with a focus on simplicity.

Vitest

Vitest is a blazing-fast unit test framework powered by Vite.

React Testing Library

React Testing Library provides simple and complete React DOM testing utilities.

Cypress

Cypress is a next-generation front-end testing tool built for the modern web.

Playwright

Playwright enables reliable end-to-end testing for modern web apps.

9. Forms

React Hook Form

React Hook Form provides performant, flexible, and extensible forms with easy-to-use validation.

Formik

Formik is the world's most popular open-source form library for React and React Native.

Final Form

Final Form is a framework-agnostic library for managing form state in React.

10. Mobile

React Native

React Native enables you to build mobile applications using only JavaScript and React.

11. Advanced Topics

Suspense

React Suspense lets you wait for some code to load and declaratively specify a loading state while waiting.

Portals

Portals provide a way to render children into a DOM node that exists outside the DOM hierarchy of the parent component.

Error Boundaries

Error Boundaries are React components that catch JavaScript errors anywhere in their child component tree, log those errors, and display a fallback UI instead of the component tree that crashed.

Fiber Architecture

React Fiber is the new reconciliation algorithm in React 16.

Remix

Remix is a full stack web framework that lets you focus on the user interface and works back through web fundamentals to deliver a fast, slick, and resilient user experience.

Next.js

Next.js is a React framework that enables functionality such as server-side rendering and generating static websites for React-based web applications.

Conclusion

Following this roadmap will ensure you have a comprehensive understanding of React and its ecosystem.
