React Learning Resources

A curated list of resources to learn React and related web technologies as fast as possible. The goal is to help you create production quality React apps even if you are starting from scratch. Just bring plenty of motivation and perseverance 😄

If you are curious, this is my preferred React stack:

Core

• TypeScript for type safety
• React - for building component-based UIs
• React Context & hooks for state management

Foundational libraries

• React Router for navigation
• React Query for fetching data using REST
• Apollo GraphQL for fetching data using GraphQL
• React Hook Form for form handling
• ag-Grid - a feature-packed JavaScript grid
• Highcharts for interactive charts

Essential tools

• Storybook to develop UI components in isolation
• React Testing Library for unit testing
• Cypress for end-to-end testing
• Mock Service Worker to mock HTTP requests
• Prettier to format code consistently

I have created the React Accelerate template to kick-start React apps using the above stack.

P.S. If you find this content useful, please show your appreciation by starring this repository.

The React Crash Course

This crash course is designed to teach you React and related web technologies as fast as possible. Feel free to skip any topic that you already know. For video tutorials, I highly recommend to type along with the instructor to have it sink in faster.

• CSS Crash Course For Absolute Beginners (1:25) by Brad Traversy
• Flexbox CSS In 20 Minutes (20:00) by Brad Traversy
• JavaScript Crash Course For Beginners (1:40) by Brad Traversy
• TypeScript Crash Course (0:53) by Brad Traversy
• React Crash Course (1:49) by Brad Traversy
• Jest Crash Course (0:57) by Brad Traversy (does not cover mocking, see below for mocking)
• Jest Crash Course (start at 0:50 for mocking) by Laith Harb
• Coding Conventions and Patterns by Naresh Bhatia

  • Application State Management with React - makes a case for using React Context and Hooks to manage state vs. external libraries like Redux
  • How to use React Context effectively - describes a nice pattern for using React Context
  • Should I useState or useReducer? - both can be used for most state management scenarios, however depending on the scenario, one may be cleaner than the other
