Learn how to deploy a Rust web server to Heroku

Axum is an asynchronous web framework built on the Tokio project, providing a minimal layer over hyper and compatibility with the Tower ecosystem to support middleware integration. The article provides a walkthrough on deploying a Rust web server using axum on Heroku, leveraging tools such as GitHub Actions for continuous integration and deployment. Axum facilitates route management and handler functions, enabling both GET and POST request handling, and supports JSON serialization and deserialization. The framework also includes extractors for shared state management across server handlers. GitHub Actions automate testing, building, and deploying Rust applications, while Heroku uses community buildpacks for Rust apps, despite lacking an official Rust buildpack, with deployment facilitated through GitHub Actions and tools like akhileshns/heroku-deploy. The article emphasizes the seamless integration of these technologies to create efficient, scalable Rust web servers, highlighting the potential for enhanced performance monitoring using LogRocket.
