Question

How to setup Node.js project?

I'm starting a new project and need to set up a Node.js environment. Can someone guide me through the setup process step by step?

Answer 1

Here's a short guide to set up a Node.js project:

1. Install Node.js

·         Download and install Node.js from nodejs.org.

2. Create a Project Directory

mkdir my-node-project

cd my-node-project

3. Initialize the Project

npm init -y

This creates a package.json file with default settings.

4. Install Dependencies

Install necessary packages (e.g., express):

npm install express

5. Create the Entry File

Create an index.js file:

touch index.js

6. Write a Simple Server

Add the following to index.js:

const express = require('express');

const app = express();


app.get('/', (req, res) => {

  res.send('Hello, World!');

});

app.listen(3000, () => {

  console.log('Server running on http://localhost:3000');

});

7. Run the Project

Start the server:

node index.js

Run the server with:

bash

npm start
