Set Up Actix Web

Explore the steps for setting up Actix Web in Rust projects. Learn how to create basic HTTP endpoints, return JSON responses, implement middleware like logging, and write tests to validate your web server functionality.

We'll cover the following...

[dependencies]
actix-web = "3"

Next, we run cargo build to install the dependency.

Now, we’re ready to write our Hello World application.

Rust 1.40.0
use actix_web::{web, App, HttpRequest, HttpServer, Responder};
async fn greet(req: HttpRequest) -> impl Responder {
    let name = req.match_info().get("name").unwrap_or("World");
    format!("Hello {}!", &name)
}
#[actix_web::main]
async fn main() -> std::io::Result<()> {

        App::new()
            .route("/{name}", web::get().to(greet))
    })
    .bind(("127.0.0.1", 8080))?
    .run()
    .await
}

We create an async ...
