1. Introduction to Next.js​

  • What is Next.js and why use it?
  • Comparing Next.js to React
  • Setting up a Next.js project (create-next-app)
  • File-based routing in Next.js

2. Client-Side Rendering (CSR)​

  • When and how to use CSR in Next.js
  • Fetching data on the client side using hooks (useEffect, useState)
  • Combining CSR with other rendering methods

3. Static Site Generation (SSG)​

  • Generating static pages with getStaticProps
  • Dynamic static pages with getStaticPaths
  • Incremental Static Regeneration (ISR)

4. Server-Side Rendering (SSR)​

  • Understanding SSR vs. Static Site Generation (SSG)
  • Using getServerSideProps to fetch data on the server
  • Benefits and trade-offs of SSR

5. Pages and Routing​

  • Creating pages
  • Dynamic routing with param].js
  • Nested routes
  • Catch-all routes (...param].js)
  • API routes

6. Data Fetching​

  • Using getServerSideProps for server-side data fetching
  • Using getStaticProps and getStaticPaths for static data fetching
  • Fetching data with external APIs or databases

7. API Routes​

  • Creating custom backend endpoints in the pages/api/ directory
  • Handling HTTP methods (GET, POST, PUT, DELETE)
  • Connecting API routes to a database (e.g., MongoDB, PostgreSQL)
  • Securing API routes (e.g., with authentication)

8. Middleware​

  • Introduction to Next.js Middleware
  • Writing and using middleware for custom logic
  • Middleware for authentication, logging, or redirection
  • Understanding next.config.js for middleware configuration

9. Styling in Next.js​

  • CSS Modules for scoped styles
  • Using global styles
  • Tailwind CSS integration
  • Styled-components or Emotion for CSS-in-JS

10. Authentication and Authorization​

  • Implementing authentication with libraries like next-auth
  • Using JWT for custom authentication
  • Protecting API routes and pages
  • Role-based access control

11. Image Optimization​

  • Using the Next.js Image component
  • Automatic image optimization with lazy loading
  • Configuring external image domains

12. Performance Optimization​

  • Code splitting and lazy loading
  • Prefetching and preloading data
  • Optimizing server-side and client-side rendering
  • Using next/image and next/font for performance

13. Deployment​

  • Deploying Next.js apps on Vercel (recommended)
  • Hosting on other platforms like AWS, Netlify, or DigitalOcean
  • Setting up environment variables for production
  • Optimizing the build process (next build)

14. Internationalization (i18n)​

  • Configuring built-in i18n support in Next.js
  • Localizing pages and components
  • Managing translations

15. Advanced Topics​

  • Custom _app.js and _document.js
  • Customizing the server with a custom server setup
  • Using next.config.js for custom configurations
  • Advanced middleware patterns

16. Testing​

  • Writing unit tests with Jest
  • Testing React components with React Testing Library
  • End-to-end testing with Puppeteer
  • Testing API routes and server-side logic

17. SEO and Metadata​

  • Managing metadata with the Head component
  • Creating dynamic metadata for SEO
  • Open Graph and social media meta tags

18. Error Handling​

  • Handling errors in server-side and client-side rendering
  • Custom error pages
  • Using error boundaries for React components

19. Integrating with Frontend and Backend​

  • Combining Next.js frontend with a separate backend
  • Creating a full-stack Next.js app with integrated APIs
  • Proxying API requests during development
