Unleashing the Power Trio: Node.js, Express, and MongoDB

In this tutorial, we'll walk through the process of creating a new project using Node.js, Express, and MongoDB, step by step.

Step 1: Set Up Your Project Directory

mkdir my_project
cd my_project

Step 2: Initialize Your Project

npm init -y

Step 3: Install Dependencies

npm install express mongoose

Step 4: Create Your Server File

touch server.js

Step 5: Write Your Server Code

Open server.js in your preferred code editor and add the following code:

const express = require('express');
const mongoose = require('mongoose');

const app = express();
const PORT = process.env.PORT || 3000;

mongoose.connect('mongodb://localhost/my_database', {
    useNewUrlParser: true,
    useUnifiedTopology: true
}).then(() => {
    console.log('Connected to MongoDB');
}).catch((err) => {
    console.error('Error connecting to MongoDB:', err);
    process.exit(1);
});

app.get('/', (req, res) => {
    res.send('Hello World!');
});

app.listen(PORT, () => {
    console.log(`Server is running on port ${PORT}`);
});

Step 6: Run Your Server

node server.js

Your server should now be running, and you can access it by navigating to http://localhost:3000 in your web browser.

Congratulations! You've successfully created a new project using Node.js, Express, and MongoDB.
