• Express routing
• Route parameters
• Query parameters
• Middleware
• HTTP methods
• CRUD operations
• JSON APIs
• Static file serving

• JavaScript fetch()

Example:

curl http://localhost:3000/books

• No database
• Data is stored in memory
• All books are lost when the server restarts
• No authentication
• No persistent storage

• Add SQLite or PostgreSQL
• Add request validation
• Split routes into separate modules
• Add controllers and middleware
• Add user authentication
• Add pagination and sorting

• Node.js
• Express.js
