How do I use Node.js for server-side JavaScript?
Asked on Sep 18, 2024
Answer
Node.js allows you to run JavaScript on the server side, enabling you to build scalable network applications. Here's a simple example of creating a basic HTTP server using Node.js.
<!-- BEGIN COPY / PASTE -->
const http = require('http');
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello, World!\n');
});
const PORT = 3000;
server.listen(PORT, () => {
console.log(`Server running at http://localhost:${PORT}/`);
});
<!-- END COPY / PASTE -->Additional Comment:
✅ Answered with JavaScript best practices.- This code creates an HTTP server using Node.js's built-in "http" module.
- The server listens on port 3000 and responds with "Hello, World!" to any incoming requests.
- To run this server, save the code to a file (e.g., "server.js") and execute it using the command "node server.js" in your terminal.
- Ensure Node.js is installed on your system to execute the code.
