Prerequisites

Before we begin the MongoDB installation, ensure that you have the following:

• A macOS system with an updated version.
• Homebrew package manager installed on your Mac.
• Basic understanding of the terminal for running commands.

Step-by-Step Guide to Install MongoDB on macOS

Step 1: Install Homebrew

If you don't already have Homebrew installed, you can install it by running the following command in your terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Homebrew is essential for managing packages and dependencies required for MongoDB setup.

Step 2: Install MongoDB Community Edition

Run the following command to install MongoDB Community Edition, which is ideal for development purposes:

brew tap mongodb/brew brew install mongodb-community@6.0

This command will download and install the latest stable version of MongoDB for macOS.

Step 3: Start MongoDB Service

After installation, start the MongoDB service by executing:

brew services start mongodb/brew/mongodb-community

You can verify that the service is running with:

brew services list

Step 4: Access MongoDB Shell

To interact with the database, open the MongoDB shell by typing:

mongosh

The MongoDB shell is a powerful tool for executing MongoDB commands, performing CRUD operations, and running queries.

Installing MongoDB Compass

In addition to the command line, you can use MongoDB Compass, a graphical interface for managing databases:

1. Download MongoDB Compass from the official MongoDB website.
2. Install the application by dragging it to your Applications folder.
3. Open Compass, connect to your database, and start visualizing your data.

Using MongoDB Atlas for Cloud Hosting

If you prefer cloud hosting, consider using MongoDB Atlas, a fully-managed database service. Here's how to get started:

• Create an account on the MongoDB Atlas website.
• Set up a cluster and configure your IP whitelist for secure access.
• Connect to the cluster using your application or MongoDB Compass.

Basic MongoDB Commands

Here are some essential commands to get started:

// Show databases show dbs; // Create or switch to a database use myDatabase; // Insert data db.myCollection.insert({ name: "John", age: 30 }); // Query data db.myCollection.find();

MongoDB Best Practices

While working with MongoDB, follow these best practices:

• Use indexes for better query performance.
• Optimize data modeling for your application requirements.
• Enable security features like authentication and IP whitelisting.
• Regularly back up your databases.
