To connect Node.js to MongoDB and easily run CRUD operations, just follow these simple steps:

1. Install Dependencies: First, make sure you have the MongoDB driver installed. You can do this using npm by running:

   npm install mongodb
   

2. Set Up Connection: Next, you need to connect to your MongoDB. You can do this with the MongoClient:

   const { MongoClient } = require('mongodb');
   const uri = 'your_mongodb_connection_string';
   const client = new MongoClient(uri);
   

3. Perform CRUD Operations: Now you can do the main tasks—Create, Read, Update, and Delete—like this:

   • Create: To add new data, use: await collection.insertOne(data);
   • Read: To get your data, use: const items = await collection.find().toArray();
   • Update: To change existing data, use: await collection.updateOne(filter, { $set: update });
   • Delete: To remove data, use: await collection.deleteOne(filter);

By following these steps, you'll be ready to handle basic operations with MongoDB!
