Web Development in Practice

📖 Learning Objectives

Learn to build web applications with Rust, master the Axum framework, database operations, API design, and deployment, contrasting with JavaScript's web development ecosystem.

🎯 Web Framework Comparison

JavaScript's Web Development

JavaScript uses frameworks like Express.js:

Rust's Web Development

Rust uses the Axum framework:

Web Framework Differences

1. Performance: Rust compiles to machine code, higher performance
2. Type Safety: Rust compile-time checks, JavaScript runtime checks
3. Memory Safety: Rust no data races, JavaScript single-threaded event loop
4. Ecosystem: JavaScript ecosystem more mature, Rust ecosystem rapidly growing

🗄️ Database Operations

Using SQLx for Database Operations

Production Error Handling Tips

In production environments, operations like database connections and initialization should have more robust error handling. For example, use Result and Box<dyn std::error::Error> to catch and propagate all possible errors, rather than simply using unwrap() or expect(). This ensures that the application can fail gracefully or provide meaningful error messages when encountering database issues.
