Learning Azure Cosmos DB

By: Shahid Shaikh

Overview of this book

<p>Microsoft has introduced a new globally distributed database, called Azure Cosmos DB. It is a superset of Microsoft's existing NoSQL Document DB service. Azure Cosmos DB enables you to scale throughput and storage elastically and independently across any number of Azure's geographic regions.</p> <p>This book is a must-have for anyone who wants to get introduced to the world of Cosmos DB. This book will focus on building globally-distributed applications without the hassle of complex, multiple datacenter configurations. This book will shed light on how Cosmos DB offers multimodal NoSQL database capabilities in the cloud at a scale that is one product with different database engines, such as key-value, document, graph, and wide column store. We will cover detailed practical examples on how to create a CRUD application using Cosmos DB with a frontend framework of your choice. This book will empower developers to choose their favorite database engines to perform integration, along with other systems that utilize the most popular languages, such as Node.js. This book will take you through the tips and trick, of Cosmos DB deployment, management, and the security offered by Azure Cosmos DB in order to detect, prevent, and respond to database breaches.</p> <p>By the end of this book, you will not only be aware of the best capabilities of relational and non-relational databases, but you will also be able to build scalable, globally distributed,<br />and highly responsive applications.</p>

Node.js setup


You need to install and set up Node.js on your machine. Go to the official Node.js website (https://nodejs.org/en/download/) and download the latest version, depending upon your operating system.

I am covering the installation for the Ubuntu here. Let's go through the steps:

  1. Open your Terminal and run this command:
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -

This will add the Ubuntu repository entry for Node.js version 8+.

  1. Now, run this command to install Node.js:
sudo apt-get install -y nodejs

After a while Node.js, along with NPM, will be set up.

  1. To check the version of Node.js and NPM, run the following command:
node -vnpm -v

The output is as follows:

You can run a similar command in Mac as well as in Windows (using PowerShell or Windows Command Prompt).

This should ensure that Node.js is set up properly and we can proceed with the Cosmos DB MongoDB creation.
