Rust Web API

Introduction

This page is to point me in the right direction should someone want to do this in rust. I think that Golang, C# or NodeJS (to reduce technology) might be a better choice. This language seems a lot harder to learn. Maybe if you already use it for other stuff in you company. Doing this I was surprise how easy it was. Maybe microcontrollers have clouded my judgement

Server

I am sure there are many choices knowing rust but this is the first one I came across. May rewrite this as we go but here we are

    HttpServer::new(move || {
        App::new()
            .app_data(repository::AppState::new(db.clone()))
            .wrap(Logger::default())
            .configure(routes::home_routes::config) // Better Approach
            .service(hello) // Sample route 1
            .service(echo)  // Sample route 2 
            .route("/hey", web::get().to(manual_hello))
    })
    .bind((address, port))?
    .run()
    .await

Routes

Here is the example for the routes. We will need to look at middleware no doubt

pub fn config(config: &mut web::ServiceConfig) {
    config.service(
        web::scope("/home")
            .service(handlers::home_handlers::greet)
            .service(handlers::home_handlers::test),
    );
}

Handlers

And here are the handlers which I will hopefully update to have your 401, 404 etc

use actix_web::{get, web, Responder};

#[get("/greet/{name}")]
pub async fn greet(name: web::Path<String>) -> impl Responder {
    format!("Hello {name}!",)
}

#[get("/test")]
pub async fn test() -> impl Responder {
    format!("Hello world!")
}
