React 19 Roadmap: Because HTML Was Too Boring

Context :

“Why write HTML when you can overthink with React 19?”

Welcome to the React 19 roadmap — smarter components, sneakier compiler, and useEffect still haunts us all.
Quick setup, brain-melting hooks, and just enough memes to survive.

Let’s build (and cry) together.

1. React Fundamentals

  • JSX

  • Components (Functional vs Class — focus on functional)

  • Props and State

  • Event Handling

  • Conditional Rendering

  • Lists and Keys

  • Forms and Controlled Components

2. React Hooks (Core)

  • useState

  • useEffect

  • useRef

  • useContext

  • useReducer (for more complex state logic)

3. Component Patterns

  • Lifting state up

  • Prop drilling

  • Composition vs Inheritance

  • Controlled vs Uncontrolled components

  • Reusable components

4. React Router (for SPA navigation)

  • react-router-dom (v6+)

    • Routes, useNavigate, useParams, Outlet, nested routes

5. State Management

  • Context API (basic to intermediate)

  • Redux Toolkit (optional but preferred in bigger apps)

    • Store, slice, asyncThunk, devtools, selectors

6. API Handling

  • fetch / axios

  • useEffect for data fetching

  • Error & loading states

  • Async/Await

  • Optional: react-query (TanStack Query) for caching and advanced fetching

7. Styling in React

  • CSS Modules / SCSS

  • Styled-components (or Emotion)

  • Tailwind CSS (preferred in modern dev)

  • Responsive design (Flexbox, Grid, Media Queries)

8. Form Handling & Validation

  • Controlled Inputs

  • Libraries:

    • react-hook-form (recommended)

    • yup or zod for schema validation

9. Project Structure & Best Practices

  • File/folder structure (e.g., components, pages, hooks, utils)

  • Naming conventions

  • Reusable components

  • Clean code, DRY principle

10. Testing Basics

  • Unit testing with Jest & React Testing Library

  • Testing components, props, and async logic

11. Authentication (Frontend)

  • Token-based auth (JWT)

  • Route guards

  • Protected routes using context

  • Login/logout state handling

12. Deployment & Optimization

  • Code splitting and lazy loading (React.lazy, Suspense)

  • Basic performance optimization (useMemo, useCallback)

  • Deployment: Vercel, Netlify, Firebase Hosting

13. Version Control & Collaboration

  • Git (commits, branches, merges)

  • GitHub (PRs, issues)

  • Understanding of basic CI/CD pipelines is a plus

Bonus: Learn basics of TypeScript with React

  • Typing props, state, and components

  • Interfaces and types for common React patterns
