MongoDB CRUD Operations

Master fundamental MongoDB Create, Read, Update, Delete operations.

Quick Start

Connect to MongoDB

const { MongoClient } = require('mongodb');

const client = new MongoClient('mongodb://localhost:27017');
await client.connect();

const db = client.db('myapp');
const users = db.collection('users');

Create Documents

// Insert one document
const result = await users.insertOne({
  name: 'John Doe',
  email: '[e-mail]',
  age: 30,
  createdAt: new Date()
});
console.log('Inserted ID:', result.insertedId);

// Insert multiple documents
await users.insertMany([
  { name: 'Alice', email: '[e-mail]' },
  { name: 'Bob', email: '[e-mail]' }
]);

Read Documents

// Find one document
 user =  users.({ :  });


 allUsers =  users.({}).();


 activeUsers =  users.({ :  }).();


 {  } = ();
 user =  users.({ :  () });
