In this article, you'll learn how to build a secure and efficient backend API in Rust with JWT access and refresh tokens functionality. We'll leverage the high-performance Axum framework and SQLX to store data in a PostgreSQL database.

• Set up and Run the Axum API on your Machine
• Run the Axum API with a Frontend App
• Set up the Rust Project with Cargo
• Launch PostgreSQL, Redis and pgAdmin Servers
• Perform Database Migration with SQLx-CLI
• Load the Environment Variables into the App
• Connect the Axum Server to the Redis and Postgres Servers
• Define the SQLX Database Model
• Define the API Response Structs
• Generate the RS256 Private and Public Keys
• Create Helper Functions to Sign and Verify the JWTs
  • Function to Sign the JWT using the Private Key
  • Function to Verify the JWT using the Public Key
• Create an Axum JWT Middleware Guard
• Implement the JWT Authentication Route Handlers
  • Create Utility Functions
  • Route Handler to Register Users
  • Route Handler to Sign In Users
  • Route Handler to Refresh the JWTs
  • Route Handler to Logout Users
  • Route Handler to Fetch the Authenticated User
  • The Complete Code of the Route Handlers
• Create Axum Routes for the Handler Functions
• Register the Axum Router and Set up CORS
