4. Step-by-Step Guides, Tutorials, and Examples

Rust

Building a Simple Web Server:

use actix_web::{web, App, HttpResponse, HttpServer};

#[actix_web::main]
async fn main() -&gt; std::io::Result&lt;()&gt; {
    HttpServer::new(|| {
        App::new()
            .route("/", web::get().to(index))
    })
    .bind("127.0.0.1:8080")?
    .run()
    .await
}

async fn index() -&gt; HttpResponse {
    HttpResponse::Ok().body("Hello from Rust!")
}

This code creates a simple web server using Actix Web that listens on port 8080 and responds with "Hello from Rust!" when accessed.

Node.js

Building a Simple REST API:

const express = require('express');
const app = express();
const port = 3000;

app.get('/api/users', (req, res) =&gt; {
  res.json({ message: 'Welcome to the user API!' });
});

app.listen(port, () =&gt; {
  console.log(`Server listening at http://localhost:${port}`);
});

This code uses Express.js to create a simple REST API endpoint that responds with a JSON message when accessed.
