Initialize Your Project Create a new project directory and initialize it with npm:

mkdir my-node-server
cd my-node-server
npm init -y

Install Essential Dependencies Install the necessary packages for your server:

npm install express cors dotenv cookie-parser body-parser jsonwebtoken bcrypt uuid

For development convenience, install nodemon to automatically restart the server on code changes:

npm install --save-dev nodemon

Configure package.json Update your package.json to include the following:

{
  "type": "module",
  "scripts": {
    "dev": "nodemon index.js"
  }
}

Setting "type": "module" enables ES6 module syntax.

Create the Server Entry Point In the root directory, create an index.js file with the following content:

import express from 'express';
import dotenv from 'dotenv';
import cors from 'cors';
import cookieParser from 'cookie-parser';
import bodyParser from 'body-parser';

dotenv.config();

const app = express();

// Middleware
app.use(express.json());
app.use(cookieParser());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

// CORS configuration
const allowedOrigins = [
  'http://localhost:5173',
  'http://localhost:5174',
  'http://localhost:3000'
];

app.use(cors({
  origin: allowedOrigins,
  methods: ['GET', 'POST', 'PUT', 'DELETE'],
  credentials: true
}));

// Static files
app.use(express.static('public'));

// Routes
app.get('/', (req, res) => {
  res.send('Welcome to the Running Server');
});

// Start the server
const PORT = process.env.PORT || 8080;
app.listen(PORT, () => {
  console.log(`Server is running at http://localhost:${PORT}`);
});

Set Up Environment Variables Create a .env file in the root directory to store environment-specific variables:

PORT=8080
JWT_SECRET=your_jwt_secret_key
DB_HOST=localhost
DB_USER=root
DB_PASSWORD=your_db_password
DB_NAME=your_db_name

Ensure that .env is listed in your .gitignore to prevent sensitive information from being committed to version control.

Create a .gitignore File In the root directory, create a .gitignore file with the following content:

# Node modules
node_modules/

# Logs
logs
*.log
npm-debug.log*

# Environment variables
.env

# OS-specific files
.DS_Store

# IDE-specific files
.vscode/
.idea/

Start the Development Server Run the server in development mode using nodemon:

npm run dev

wow! you are creating your frist server . welcome to the server should now be running at http://localhost:8080.

if need a any package update please follow this

npm outdated

9.When ready, update all packages:

npm install -g npm-check-updates
ncu -u
npm install
