Course Structure:
1. Introduction to React
- What is React? Key concepts and the advantages of using React for web development. - How React works: The virtual DOM and reconciliation process. - Setting up a React environment: Create React App, Node.js, npm, and JSX. - Understanding the React ecosystem: React Developer Tools, Babel, Webpack. - Building your first React application: A simple “Hello World” example.
2. React Components and JSX
- Introduction to React components: Functional vs. Class components. - Understanding JSX: How JSX works and how it translates to JavaScript. - Props: Passing data to components through props. - Children in React: How to manage children components and dynamic content. - Handling events in React: Using event handlers like onClick, onSubmit, etc. - Conditional rendering: How to display content based on conditions.
3. State Management in React
- Understanding React state: The concept of state and how it differs from props. - Using the `useState` Hook for managing local component state in functional components. - Handling forms and user input: Using controlled components for form inputs. - Lifting state up: How to pass state between components and manage shared state. - The Context API: Managing global state for small to medium-sized applications.
4. React Hooks
- Introduction to React Hooks: Why and how Hooks replace lifecycle methods in functional
components. - The `useEffect` Hook: Handling side effects such as data fetching and subscriptions. - The `useContext` Hook: Simplifying state management with context. - The `useReducer` Hook: Managing complex state logic with reducers. - Custom Hooks: Creating reusable hooks for modular and cleaner code. - Best practices for using Hooks in React applications
5. React Router
- Introduction to React Router: Routing in single-page applications (SPA). - Setting up React Router and understanding its core components: `Route`, `Switch`, and `Link`. - Dynamic routing: Using route parameters and query strings. - Nested routing: How to organize routes within parent-child structures. - Redirecting users: Implementing navigation and programmatic routing. - Protecting routes: Managing private routes and user authentication flows.
6. State Management with Redux
- Introduction to Redux: Centralized state management in React applications. - Understanding Redux architecture: Actions, reducers, and the store. - Using Redux with React: Connecting components to the Redux store using `connect` and
`useSelector`. - Dispatching actions and updating state in the Redux store. - Middleware in Redux: Using middleware like Redux Thunk for async actions. - Advanced Redux patterns: Normalizing state and utilizing selectors.
7. Component Lifecycle and Side Effects
- Understanding the React component lifecycle: Mounting, updating, and unmounting. - Class components vs. functional components lifecycle methods. - Using the `useEffect` Hook to replicate lifecycle methods like `componentDidMount`, `componentDidUpdate`, and `componentWillUnmount`. - Handling asynchronous operations in React, such as fetching data from an API. - Optimizing side effects: Cleaning up side effects with `useEffect`
8. Performance Optimization in React
- React re-rendering: Understanding when and why React re-renders components. - Memoization: Using `React.memo` to prevent unnecessary re-renders of functional components. - The `useMemo` and `useCallback` Hooks: Optimizing expensive computations and callback
functions. - Lazy loading components with `React.lazy` and `Suspense` for code splitting. - Virtualization techniques: Using libraries like React Virtualized for rendering large lists efficiently.
9. Testing React Applications
- Introduction to testing in React: The importance of testing and the tools available. - Setting up Jest and React Testing Library for testing React components. - Writing unit tests for functional and class components. - Mocking API calls and asynchronous data fetching in tests. - Testing component behavior and user interactions with `fireEvent`. - End-to-end testing with tools like Cypress.
10. Advanced React Patterns
- Higher-order components (HOC): Enhancing component functionality with HOCs. - Render props: Sharing logic between components through render props.
- Controlled and uncontrolled components: Managing form inputs and handling DOMelements. - Context for dependency injection: Managing cross-cutting concerns like themes and
authentication.
11. Capstone Project: Building a React Application
- Building a full-fledged React application from scratch. - Incorporating React Router for navigation, Redux for state management, and Axios for data
fetching. - Implementing authentication and authorization flows using JWT. - Writing tests to ensure the app’s functionality is correct and robust. - Optimizing the app for performance and scalability. - Deploying the application to a cloud platform like Netlify or Vercel.
Learning Methodology:
