Setup and Insert Data

• Initialize the database and insert sample data.
• Script: 01_setup.mongodb.js

Example:

// Connect to MongoDB
const { MongoClient } = require("mongodb");
const url = "mongodb://localhost:27017";
const client = new MongoClient(url);

async function run() {
  try {
    await client.connect();
    console.log("Connected to MongoDB!");
    const db = client.db("ecommerce");
    const products = db.collection("products");
    // More setup code...
  } finally {
    await client.close();
  }
}

run().catch(console.error);

Reading Data

• Find all documents and pretty print them.
• Filter data using queries.
• Script: 02_reading.mongodb.js

Example:

db.products.find();
db.products.find().pretty();

Updating Documents

• Update single and multiple documents.
• Script: 03_update.mongodb.js

Example:

db.products.updateOne({ name: "Wireless Mouse" }, { $set: { price: 899 } });

Deleting Documents

• Delete individual and multiple documents.
• Script: 04_delete.mongodb.js

Example:

db.contacts.deleteOne({ name: "Alice" });

Aggregation Examples

• Perform aggregation operations like $match, $group, and $sort.
• Script: 05_aggregation.mongodb.js

Example:

db.orders.aggregate([{ $group: { _id: "$status", totalOrders: { $sum: 1 } } }]);

Indexing and Performance

• Create and manage indexes for better performance.
• Script: 06_indexes.mongodb.js

Example:

db.products.createIndex({ name: 1 });

Admin Commands

• Useful commands for managing the database.
• Script: 07_AdminCommands.mogodb.js

Example:

db.stats();
db.serverStatus();
