Ultimate React Course - From Zero to Hero

Course Objectives

  • Learn everything about React from basics to advanced concepts.
  • By the end, build and deploy fast and scalable React apps.
  • No prior knowledge of React needed; HTML, CSS, and JavaScript basics required.
  • Comprehensive, easy to follow, practical course building a production-grade video game discovery app.
  • Advanced topics: routing, state management, data fetching, authentication, error handling, performance optimization.

Course Structure

  1. Introduction

    • Instructor: Mosh Hamedani
    • Experience: 20 years in software engineering
    • Teaching: Millions via YouTube and online school
    • Tools: Node.js (v16+), Visual Studio Code (with Prettier extension)

  2. Setting Up Development Environment

    • Install Node.js
    • Use Visual Studio Code with Prettier extension
    • Create a React application using create-react-app or Vite
      • Recommended: Vite (faster and smaller bundle sizes)
    • Steps:
      • Open terminal
      • Run npm create vite@latest
      • Install necessary dependencies: npm install
      • Open project in VS Code and start development server: npm run dev

  3. Understanding React

    • React: JavaScript library for building dynamic UIs.
    • Origins: Created at Facebook in 2011
    • Difference from Vanilla JavaScript: Components and Virtual DOM
      • Components: Reusable, modular code blocks
      • Virtual DOM: Efficiently updates elements

  4. React Basics

    • Create function-based components (preferred over class-based)
    • JSX: JavaScript XML for UI rendering
    • Dynamic rendering using JavaScript expressions within JSX
    • Using Props: Passing data to components
    • State Management: Using useState hook for dynamic behavior
    • Event Handling: Handling click events and updating states

  5. Advanced Concepts

    • Component Tree
      • App structure visualized as a tree
    • Props vs. State
      • Props: Read-only data passed to components
      • State: Internal data that can change over time
      • Changes in props/state trigger React to re-render components
    • Conditional Rendering
      • Using ternary operators and logical operations for dynamic content display
    • Handling Events
      • Attaching and responding to user events (e.g., clicks)
    • Children Prop
      • Passing nested elements/content to components
    • React DevTools
      • Browser extension for inspecting and analyzing React apps

  6. Building a Sample App

    • List Group Component: Dynamic lists with mapping and index handling
    • Alert Component: Dismissable alerts with state management
    • Button Component: Dynamic and event-driven buttons with strict type safety using TypeScript

Exercises and Challenges

  • Create button components and handle events to display alerts
  • Make components reusable with props and dynamic states
  • Ensure type safety and proactively catch errors with TypeScript

Conclusion

  • Encourage to check out the complete React course
  • Course provides exercises, summary notes, cheat sheets, and full project guidance
  • Includes 30-day money-back guarantee
