Path Curriculum
JSX, components, and the virtual DOM
Understand why React re-renders, what reconciliation does, and how keys matter.
Props, state, and event handling
Pass data down with props, lift state up, and handle user events without side effects.
Core hooks: useState, useEffect, useRef
Manage local state, run effects on mount and dependency changes, and access DOM nodes.
Conditional rendering and list rendering
Render UI based on state, map arrays to elements, and avoid key pitfalls in lists.
useReducer for predictable state transitions
Model complex state machines with actions and reducers, test transitions in isolation.
Context API for cross-component state
Create providers and consumers, avoid unnecessary re-renders with context splitting.
Custom hooks for reusable logic
Extract stateful logic into hooks like useLocalStorage, useDebounce, and useMediaQuery.
TanStack Query v5 for server state
Define queries and mutations, handle loading/error states, and set up background refetching.
Client-side routing with React Router v6
Declare routes, navigate programmatically, and lazy-load route components with Suspense.
Optimistic updates and cache invalidation
Update the UI instantly on mutation and revert gracefully if the server request fails.
Responsive layouts with Tailwind CSS
Apply mobile-first breakpoints, flexbox, and grid utilities to build adaptive UIs fast.
Accessible forms and focus management
Use aria-label, role, and focus trapping to make dialogs and forms keyboard-navigable.
Dark mode and CSS custom properties
Toggle themes with a CSS variable strategy that works across Tailwind and raw CSS.
Animations with Framer Motion basics
Add entrance animations, layout transitions, and gesture-based interactions declaratively.
Component testing with Vitest and Testing Library
Render components, fire user events, and assert on accessible roles and text content.
Code splitting, lazy loading, and memoisation
Use React.lazy, Suspense, useMemo, and useCallback to eliminate unnecessary renders.
Deploying to Vercel and measuring Core Web Vitals
Connect a GitHub repo, configure preview deployments, and interpret LCP and CLS scores.
