Now that you’re familiar with Rust’s fundamentals, its concurrency model, error handling, and ecosystem, it’s time to put your knowledge into practice by building a simple web application. This project will guide you through setting up your project environment, implementing the application logic, and finalizing your project.
First, create a new Rust project:
cargo new rust_web_app cd rust_web_app
Then, add necessary dependencies in your Cargo.toml:
Cargo.toml
[dependencies] warp = "0.3" tokio = { version = "1", features = ["full"] } serde = { version = "1.0", features = ["derive"] }
We’ll use warp for the web server framework, tokio for asynchronous runtime, and serde for serializing and deserializing the JSON data.
warp
tokio
serde
Create a new file in the src directory called server.rs. Here, you will define your routes and request handlers. Start with a simple health check endpoint:
src
server.rs
use warp::Filter; async fn health_check() -> Result<impl warp::Reply, warp::Rejection> { Ok("OK") } pub fn routes() -> impl Filter<Extract = impl warp::Reply, Error = warp::Rejection> + Clone { warp::path!("health").and(warp::get()).and_then(health_check) }
In your main.rs, set up the server to run:
main.rs
use warp::Filter; mod server; #[tokio::main] async fn main() { let routes = server::routes(); warp::serve(routes).run(([127, 0, 0, 1], 3030)).await; }
Before running your application, review the code to ensure it follows best practices and that you’ve handled potential errors. Run your project:
cargo run
Test your application by visiting http://127.0.0.1:3030/health in a web browser or using a tool like curl:
http://127.0.0.1:3030/health
curl
curl http://127.0.0.1:3030/health
In this project, you’ve built a simple web application using Rust. You set up the project environment, implemented a basic web server, and learned how to run and test your Rust web application. This project serves as a foundation for building more complex web applications with Rust.
