Connecting Node.js to MongoDB

To use MongoDB with Node.js, follow these steps:

1. Install MongoDB Driver or Mongoose

Install Mongoose, a popular ODM library, for easy interaction with MongoDB

				
					npm install mongoose

				
			

2. Set Up MongoDB Connection

Connect your Node.js application to a MongoDB database.

Example Code:

				
					const mongoose = require('mongoose');

// Connect to MongoDB
mongoose.connect('mongodb://localhost:27017/mydatabase', {
  useNewUrlParser: true,
  useUnifiedTopology: true,
})
  .then(() => console.log('Connected to MongoDB'))
  .catch((err) => console.error('Connection error:', err));


				
			

3. Verify the Connection

Ensure the database is running and your app connects successfully. Check for error handling in case of connectivity issues.


Conclusion

Connecting Node.js to MongoDB is straightforward with Mongoose. It ensures a reliable connection and simplifies database operations, enabling efficient data management.
