MongoDB is a popular NoSQL database that is known for its flexible data model, scalability, and ease of use. With its document-oriented architecture, MongoDB is an ideal choice for developing modern applications that require a dynamic schema and the ability to handle large volumes of data. In this blog post, we will discuss how to use MongoDB locally with VS Code, one of the most popular code editors used by developers worldwide. We will also provide a detailed overview of the features and benefits of MongoDB tailored to the specific needs of VS code users.

What is MongoDB?

MongoDB is a document-oriented NoSQL database that stores data in BSON format, a binary representation of JSON documents. Unlike traditional relational databases that use tables and rows to store data, MongoDB uses collections and documents. A document is a set of key-value pairs that can have nested structures and arrays, making it ideal for storing complex and hierarchical data. MongoDB is also known for its ability to scale horizontally, allowing you to add more nodes to your cluster as your application grows.

What is VS Code?

Visual Studio Code (VS Code) is a lightweight and powerful code editor that is used by millions of developers worldwide. Developed by Microsoft, VS Code provides a wide range of features and extensions that make it easy to customize and enhance your development experience. Some of the key features of VS Code include:

• Code navigation and editing

• Debugging and testing

• Git integration

• Extension marketplace

• Integrated terminal

Steps to use MongoDB locally with VS Code

In this blog post, we will provide a detailed guide on how to use MongoDB locally with VS Code, one of the most popular code editors used by developers worldwide.

Step 1: Install MongoDB

Before we begin, it is important to have MongoDB installed on your local machine. You can download the latest version of MongoDB from the official website and follow the installation instructions provided.

1. Go to the MongoDB download page: https://www.mongodb.com/try/download/community

2. Select the appropriate version of MongoDB for your operating system (Windows in this case).

3. Click the "Download" button.

4. Once the download is complete, double-click the .msi installer file to start the installation process.

5. Follow the prompts in the installation wizard to complete the installation.

Step 2: Install VS Code

If you haven't already, download and install VS Code from the official website.

1. Go to the Visual Studio Code download page: https://code.visualstudio.com/download

2. Select the appropriate version of VS Code for your operating system (Windows in this case).

3. Click the "Download" button.

4. Once the download is complete, double-click the .exe installer file to start the installation process.

5. Follow the prompts in the installation wizard to complete the installation.

Step 3: Install the MongoDB extension for VS Code

1. Open VS Code and go to the Extensions panel (Ctrl + Shift + X on Windows or Cmd + Shift + X on macOS).

2. Search for "mongodb" and select MongoDB for VS Code extension.

3. Click the "Install" button to install the extension.

   You can also install the MongoDB Node.js driver using npm

    npm install mongodb
   

Step 4: Connect to a MongoDB database

Once the extension is installed, you can connect to a MongoDB database by clicking on the "MongoDB" icon in the left sidebar of VS Code. Click the "Add Connection" button to create a new connection.

Enter the connection details, including the MongoDB URI, database name, and authentication credentials if necessary.

const MongoClient = require('mongodb').MongoClient;

const uri = 'mongodb+srv://<username>:<password>@<cluster-url>/<dbname>?retryWrites=true&w=majority';

const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });

client.connect(err => {
  if (err) {
    console.error('Failed to connect to MongoDB:', err);
    return;
  }

  console.log('Connected to MongoDB!');

  // Perform database operations here...

  client.close();
});

Replace <username>, <password>, <cluster-url>, and <dbname> with your MongoDB server details.

Step 5: Manage MongoDB databases and collections

After you have connected to a MongoDB database, you can manage your databases and collections using MongoDB Explorer. The MongoDB Explorer provides a tree view of your databases and collections, allowing you to easily browse and interact with your data. You can perform a wide range of operations, including creating, deleting, and modifying databases and collections, inserting and updating documents, and executing queries and aggregations.

These are just a few examples of the many operations you can perform with MongoDB's Node.js driver.

Create a database

const db = client.db('my-database');

// If you need to create a collection, just reference it - MongoDB will create it automatically
const myCollection = db.collection('my-collection');

Insert documents into a collection

const documents = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Charlie', age: 35 }
];

myCollection.insertMany(documents, (err, result) => {
  if (err) {
    console.error('Failed to insert documents:', err);
    return;
  }

  console.log('Inserted', result.insertedCount, 'documents into my-collection');
});

Find documents in a collection

const query = { age: { $gte: 30 } }; // Find all documents where age is greater than or equal to 30

myCollection.find(query).toArray((err, documents) => {
  if (err) {
    console.error('Failed to find documents:', err);
    return;
  }

  console.log('Found', documents.length, 'documents:', documents);
});

Update documents in a collection

const filter = { name: 'Bob' }; // Find the document with name = "Bob"
const update = { $set: { age: 32 } }; // Set Bob's age to 32

myCollection.updateOne(filter, update, (err, result) => {
  if (err) {
    console.error('Failed to update document:', err);
    return;
  }

  console.log('Updated', result.modifiedCount, 'documents');
});

Delete documents from a collection

const filter = { age: { $gte: 35 } }; // Find all documents where age is greater than or equal to 35

myCollection.deleteMany(filter, (err, result) => {
  if (err) {
    console.error('Failed to delete documents:', err);
    return;
  }

  console.log('Deleted', result.deletedCount, 'documents');
});
