React JS with AI
Frontend Development Track
From a blank editor to a deployed, AI-powered web app. Modern JavaScript, React fundamentals and Hooks, routing, state management, API integration, and AI — both using AI tools to code faster and building AI features (chatbots, summarizers, smart search) inside React apps. Taught as one build-and-ship workflow, not isolated topics. Students graduate able to design, build, test and deploy a complete React application.
Web Foundations
Module 1–3F1
HTML5, CSS3 & Responsive Design
Semantic HTML, forms and accessibility basics. CSS box model, Flexbox, Grid, positioning, variables, media queries and mobile-first layouts. Building clean, responsive pages that become the base for every React component later.
Semantic HTMLFlexbox/GridResponsive
F2
Modern JavaScript (ES6+)
Variables, functions, arrow functions, destructuring, spread/rest, template literals, array methods (map, filter, reduce), modules, DOM manipulation, events, Promises, async/await and the Fetch API. The exact JavaScript React leans on every day.
▸ Goal: read and write the JavaScript patterns that appear in every React codebase without hesitation.
ES6+Array methodsAsync/awaitFetch API
F3
Dev Environment, Git & Tooling
VS Code setup, Node.js and npm, project scaffolding with Vite, browser DevTools, Git and GitHub workflow (commit, branch, pull request), and package management. Setting up a professional workflow before writing the first component.

React Core
Module 4–6R1
React Fundamentals
Why React, virtual DOM and component thinking. JSX, functional components, props, children, conditional rendering, lists and keys, event handling, and structuring a component tree. Breaking a UI design into reusable components.
JSXComponentsPropsLists & keys
R2
State & Hooks
useState, useEffect, useRef, useMemo, useCallback, useContext and useReducer. The component lifecycle through effects, data fetching on mount, cleanup, and writing your own custom hooks to share logic across components.
▸ Practical drills: build a to-do app, a weather widget and a debounced search box using hooks.

R3
Routing & Forms
Multi-page apps with React Router: nested routes, dynamic params, protected routes and navigation. Controlled forms, validation, and React Hook Form for real-world sign-up, login and checkout screens.

React Ecosystem & Production Skills
Module 7–10E1
State Management & API Integration
Context API for app-wide state, Redux Toolkit for larger apps, Axios and REST API consumption, loading and error states, and TanStack Query for caching and server state. Connecting a React front end to real data.
Context APIRedux ToolkitAxiosTanStack Query
E2
Styling & UI Libraries
Tailwind CSS, CSS Modules, and a component library (MUI or shadcn/ui). Building a consistent design system, dark mode, reusable buttons, cards and modals, and dashboards that look professional.

E3
Backend Basics for React Developers
Enough backend to ship full apps: Node.js and Express REST APIs, JSON Server for prototyping, Firebase or Supabase for auth and database, JWT authentication flow, and environment variables for keeping secrets out of the browser.
▸ Why it matters: the same backend layer later protects AI API keys in Module 12.

E4
Performance, Testing & Deployment
React.memo, lazy loading and code splitting, Lighthouse audits, unit and component testing with Vitest and React Testing Library, and deployment to Vercel or Netlify with a live URL and a CI-ready GitHub repository.

AI with React
Module 11–13AI runs through the program twice: as a tool that makes developers faster, and as a feature set students learn to build into products.
A1
AI-Assisted Development
Using GitHub Copilot, ChatGPT and Claude as coding partners: prompt engineering for code, generating components, explaining unfamiliar code, debugging errors, writing tests and refactoring. Plus when not to trust AI output and how to review it.
▸ Rule taught in this module: you own every line AI writes — read, test and understand it before committing.
CopilotPrompt engineeringAI debuggingCode review
A2
Building AI Features in React
Integrating LLM APIs into React apps: a chat interface, streaming responses, loading and error handling, conversation history, and an AI text summarizer. API keys are kept server-side through a small Node/serverless proxy, never exposed in the browser.
LLM APIChat UIStreamingSecure API proxy
A3
Smart Apps: RAG, Search & Responsible AI
Prompt design for product features, structured (JSON) outputs rendered as UI, AI-powered search and recommendations, and a beginner's introduction to retrieval-augmented generation over your own documents. Closed with an honest module on cost, privacy, bias and responsible AI use.

Practical Project — Capstone
Module 14One end-to-end product build, run the way it happens on a real team — from a client brief to a deployed, AI-powered React application.
Receive a project briefTake a real client-style brief (e.g. AI study assistant, smart job portal, AI expense tracker) and define scope and features.
Plan & design the UIWireframe screens, break them into a component tree, and plan routes and state.
Build the React front endComponents, hooks, routing, forms and styling with Tailwind or MUI, committed through Git branches.
Connect backend & authenticationREST or Firebase/Supabase data layer with login, protected routes and error handling.
Add the AI featureIntegrate an LLM-powered feature (chat, summary or smart search) through a secure server-side proxy.
Test, optimise & deployComponent tests, Lighthouse fixes, and a live deployment on Vercel or Netlify.
Demo & documentWrite a clear README, record a demo walkthrough, and present the project to a review panel.
▸ Deliverable: a live deployed app, GitHub repository with a professional README, and a demo video — used as the interview portfolio piece.
Placement & Career Preparation
Module 15P1
Getting Job-Ready
Developer resume preparation, LinkedIn and GitHub profile optimization, and a portfolio site built around the capstone project. React interview questions drilled through mock technical interviews and live-coding rounds, plus HR rounds and real interview case studies. A practical assessment before graduation, and a career roadmap covering progression into Frontend Developer, Senior React Developer, Full Stack Engineer and AI-focused engineering roles.
▸ Includes: mock technical interview, live-coding round, practical assessment, and a personalised career roadmap session.
