Node.js & Express.js Series | Chapter 9 | MongoDB Installation

Welcome to Chapter 9 of our Node.js & Express.js series. In this chapter, we will guide you through the installation of MongoDB, a popular NoSQL database, which is commonly used with Node.js and Express.js applications.

Step 1: Download MongoDB

The first step in installing MongoDB is to download the appropriate version for your operating system from the official MongoDB website. Make sure to choose the version that is compatible with your operating system.

Step 2: Install MongoDB

Once you have downloaded the MongoDB installer, follow the installation instructions provided on the MongoDB website for your specific operating system. These instructions will guide you through the installation process and set up any necessary configurations.

Step 3: Verify Installation

After the installation is complete, you can verify that MongoDB has been installed successfully by running the following command in your terminal or command prompt:

mongod --version

If MongoDB is installed correctly, you should see the version number displayed in the terminal or command prompt.

Step 4: Start MongoDB

To start the MongoDB server, run the following command in your terminal or command prompt:

mongod

This will start the MongoDB server with the default settings. You can also provide a configuration file using the --config option if you have custom configuration settings.

Step 5: Connect to MongoDB

Now that MongoDB is installed and running, you can connect to it from your Node.js and Express.js applications using a MongoDB driver such as mongodb or mongoose. Make sure to install the necessary dependencies using npm or yarn.

That’s it! You have now successfully installed MongoDB and are ready to use it with your Node.js and Express.js applications.
