Building a non-trivial web application with Rust is simplified by Axum, especially for authentication, middleware, and more complex features.
This step-by-step guide focuses on building a JWT authentication API using Rust and the Axum framework, covering endpoints, JWT middleware, and protected routes.
Installing Rust and Axum involves running commands for setting up Rust, creating a new project, and adding dependencies like tokio, bcrypt, chrono, jsonwebtoken, serde, and serde_json.
The Cargo.toml dependencies include Axum for web framework, bcrypt for password hashing, chrono for timestamps, jsonwebtoken for JWT, serde for serialization, and tokio for async runtime.
