Workshop: 2-3 days, on-site or remote
Web-based Services in Rust
Rust is an excellent programming language for developing web applications and web services due to its concurrency approach, tool flexibility, library availability, and rich ecosystem. As a result, you can create services that are fast, reliable, and cost-effective. In fact, using Rust to write services can tremendously reduce your operating costs. However, the main challenge is knowing where to start. This workshop aims to guide you through the process of building web services using the ecosystem around the Tokio async runtime. You will learn how to make basic API calls, create advanced middleware layers to add functionality, and conduct tracing and testing.
This workshop is intended for developers who have some experience with Rust and want to learn more about its problem domain for web applications. It is not necessary to have written Rust in a production environment yet. If you are just starting out with Rust, we will provide you with preparatory material beforehand.
anchorWorkshop overview
Tokio, Hyper, and Axum
We will begin by setting up a web server for our web application using the Axum framework, which is built on top of Tokio and Hyper. We will learn about the FromRequest and IntoResponse traits, Extractors, Routers, and how to connect JSON serialization and deserialization. If time permits, we will also create a web socket connection for our clients.
Tower and Middlewares
We will expand our application by creating middleware layers that handle crucial aspects such as sessions, authentication, timeouts, and compression. We will not only apply built-in middlewares but also create our own by implementing Tower's Service trait and learning more about futures and async.
Tracing, Logging, and Testing
In the final part, we will examine how to gain insights into our application's behavior and perform performance and correctness tests. Ultimately, we will be able to publish our application on AWS, Shuttle, and other services.
