About this course

React is the front-end library behind most web products, and React developer is the most advertised front-end role in India. This course teaches React the way it is written in 2026: function components and hooks, React Router, TanStack Query for server state, Zustand or Redux Toolkit for client state, Tailwind for styling, TypeScript and tests.

The course starts with the JavaScript a React developer must know (ES6+, async, modules), then React itself: JSX, components, props, state, events, lists, forms, hooks (useState, useEffect, useRef, useMemo, useCallback, custom hooks), routing with React Router, context and global state, data fetching with loading and error states, and styling with CSS modules, Tailwind and component libraries.

You then make apps production-grade: performance (memoisation, code splitting, lazy loading), accessibility, forms with React Hook Form and validation, authentication flows, testing with Vitest and React Testing Library, TypeScript, and deployment on Vercel with CI. The course ends with two portfolio apps (a product catalogue with cart and a dashboard) and interview preparation for React roles. Every topic is coded live, and every session is recorded.
