Rust Web Hosting

Rust’s fast and memory-efficient programming language makes it an excellent choice for developing backend servers, services, and web apps with server-rendered pages. Thanks to WebAssembly–a technology which enables languages like C and Rust to run in web browsers–Rust servers boast small resource footprints while still offering high performance. Furthermore, its safety and reliability make this an invaluable technology choice.

Rust’s ecosystem is mature enough for creating complete backends. There’s tokio, an asynchronous runtime which provides a solid basis for networking applications; web frameworks like Axum and Actix-Web which are both well maintained and performant; libraries covering data interactivity, security, serialization (de-/serialization), internationalization and templating are available as part of Rust.

As such, many teams are opting for incremental adoption by (re-)implementing portions of existing systems in Rust incrementally. This approach reduces risk while giving teams the chance to evaluate if Rust fits with their environment; large scale applications may even find this approach cost effective due to Rust’s strong type system which enables writing code with minimal or even no garbage collection overhead overhead costs.

In this article, we’ll look at how to get started with Rocket web framework and create an HTTP web server serving two endpoints. Next, we’ll use GitHub Actions to deploy our app onto Heroku using binary-buildpack – this action supports many community Heroku buildpacks.
