How to create a Node.js project?

I'm new to Node.js and want to create my first project. Can someone guide me through the steps to set up a basic Node.js project? Do I need any specific tools or configurations to get started? Also, are there essential commands or files I should know about, like package.json? Any tips for beginners would be helpful!

You can follow the following steps to create a Node.js project:

1. Install Node.js:

If Node.js is not installed in your computer , download and install it from it's official website.

2. Initialize the Project:

Open a terminal and create a new directory for your project:

mkdir project-namecd project-name

Initialize a new Node.js project by running:

npm init

This command will ask a series of questions (like project name, version, description, etc.). If you want to skip the questions, use:

npm init -y

Now a package.json file is created which will keeps track of your project's dependencies and configurations.

3. Install Dependencies (Optional):

Install any libraries you need, such as express for creating a server:

npm install express

4. Create the Main JavaScript File:

Create a server.js (or another name) file in the project folder:

touch server.js

Add the following example code to create a basic server using express:

const express = require('express');

const app = express();

const port = 5000; app.get('/', (req, res) => {  res.send('Hi, Eduerka!');});app.listen(port, () => {  console.log(`Server running at http://localhost:${port}`);});

5. Run the Project:

Start the server by running:

node server.js

You should see a message: Server running at http://localhost:5000.
