Web Development

This course teaches you how to build modern, dynamic web applications using React.js — one of the most popular JavaScript libraries for building user interfaces. Covering everything from components and hooks to routing, state management, API integration, and deployment, this course takes you from React basics to building and deploying real, production-ready applications.

What Will I Learn?

Build modern web applications using React components, props, and state
Master essential React Hooks including useEffect, useRef, useMemo, and custom hooks
Handle forms, validation, and user input effectively in React
Implement client-side routing using React Router, including dynamic and nested routes
Manage application-wide state using Context API and Redux Toolkit
Fetch and work with data from external APIs, including error and loading handling
Write basic tests for React components using Jest and React Testing Library
Build, optimize, and deploy a complete React application to production

Course Content

Introduction to React
This topic introduces students to React as a library, explaining its core philosophy and helping them get a working project set up so they can start writing React code right away.

Components and Props
This topic covers the building blocks of any React application — components — and how data is passed between them to create reusable, modular UI pieces.

State and Event Handling
This topic introduces state as a way for components to store and manage changing data, along with how React handles user interactions like clicks and inputs.

React Hooks (Deep Dive)
This topic goes deep into React Hooks beyond the basics, covering essential hooks for managing side effects, performance, and reusable logic — critical knowledge for building real-world React applications.

Forms in React
This topic focuses on handling user input through forms, a common requirement in most real-world applications, covering both control patterns and validation.

React Router
This topic introduces client-side routing in React, allowing applications to have multiple pages/views without full page reloads, which is essential for building single-page applications.

State Management
This topic covers how to manage state across an entire application rather than just within individual components, addressing challenges that arise as apps grow larger.

Working with APIs
This topic teaches students how React applications communicate with external data sources, a core skill for building dynamic, real-world applications.

Testing React Applications
This topic introduces the basics of testing React components, helping students ensure their applications work correctly and remain stable as they grow.

Deployment and Final Project
This final topic covers how to prepare a React application for production and deploy it live, followed by a capstone project that ties together everything learned in the course.
