Using Rust and Axum to build a JWT authentication API

Building a non-trivial web application with Rust becomes more manageable with the Axum framework, especially when implementing complex features like authentication and middleware. This guide provides a step-by-step process for creating a JWT authentication API using Rust and Axum, from setting up the necessary dependencies to defining authentication endpoints and middleware for protected routes. It involves the use of libraries such as Tokio for asynchronous functions, Serde for data serialization, BCrypt for password hashing, and JSON Web Token for secure token management. The tutorial also includes practical code examples and explanations for creating sign-in functionality, encoding and decoding JWT tokens, and protecting routes. Additionally, the guide demonstrates testing the implementation using Postman and offers resources for further exploration, such as a GitHub repository with the complete project and LogRocket for monitoring and debugging Rust applications.
