Building Backends with Node.js and MongoDB

As a seasoned backend Node.js developer, I understand the importance of creating robust and efficient applications. In this blog post, we will delve into the world of Node.js and MongoDB, exploring best practices and techniques that can help you build powerful and scalable backend systems.

To develop a Robust project the foundation needs to be strong, for that the general practice of creating a node project is shared below step-by-step

• Create a project folder like "nodeBasic" and cd into the directory.
• Run "npm init" and setup the project.
• Now type "npm i express" to add express in your dependency
• In the directory create index.js file and follow along with the code below.

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

app.get('/api/users', (req, res) => {
  const users = ['User 1', 'User 2', 'User 3'];
  res.json(users);
});

const PORT = 3000;
app.listen(PORT, () => {
  console.log(`Server listening on port ${PORT}`);
});

Express.js, a minimal and flexible web application framework for Node.js, simplifies the process of building APIs. Its middleware architecture, routing capabilities, and extensibility make it a go-to choice for backend developers.

• Now to connect the Mongo db we are going to use the most famous ODM "Mongoose"
• To install it type "npm i mongoose"
• Then follow along the code in the index.js file to connect the mongo db

const mongoose = require('mongoose');

mongoose.connect('mongodb://{localhost:PORT}/nodeBasic')
  .then(() => console.log('Connected to MongoDB'))
  .catch(error => console.error('Error connecting to MongoDB:', error));

Node.js and MongoDB form a powerful duo for backend development. With Node.js's event-driven architecture and MongoDB's flexibility, you can create highly responsive and scalable applications. By utilizing frameworks like Express.js, you can design elegant APIs that cater to your application's needs. As you embark on your backend journey, remember to prioritize code quality, security, and performance to build a foundation that stands the test of time.
