MEAN.js with Cosmos DB on Azure

(a YouTube series by John Papa)

Cosmos DB is of significant interest to myself for projects I have been engaged in for the past couple of years which use MongoDB and MEAN in several ways. Scaling for us has always been a bit of a pain with MongoDB, and Cosmos DB on Azure looks to be relieving a lot of the headaches we have had.

MEAN stands for MongoDB, Express, Angular and Node.

I am not the author of these – this is a reference list to a YouTube series by John Papa introducing MEAN with Cosmos DB on Azure. I would normally just link directly to the creators blog or post for a series such as this, but it seems to be offline just now so I thought I would share a full list of current videos here – hopefully the original link will work again soon – which is https://johnpapa.net/angular-cosmosdb-1/.

MEAN.js with Cosmos DB – Part 1: Introduction

John builds a lot of apps with MongoDB, Express, Angular and Node (MEAN). MongoDB just works so well with these, but recently he has been using Cosmos DB on Azure in its place because it’s easy to use, scale, is super fast, and he does not have to change how he codes.

MEAN.js with Cosmos DB – Part 2: Creating the Node.js and Express App

Creating a Node.js and Express App along with the Angular CLI. Then create a web API endpoint and try it out.

MEAN.js with Cosmos DB – Part 3: Angular and Express APIs

The A in MEAN stands for Angular. This video shows how to build an Angular UI that talks to the Express API, with GET, POST, PUT, and DELETE.

MEAN.js with Cosmos DB – Part 4: Creating and Deploying Cosmos DB

Using the Azure CLI, to create the Cosmos DB account to represent a MongoDB model database and deploy it to Azure. Then view what we created in the Azure portal.

MEAN.js with Cosmos DB – Part 5: Querying Cosmos DB

How to connect to the MongoDB database with Azure Cosmos DB, using Mongoose, and query it for data.

RESTful interactions with Azure Cosmos DB resources using the DocumentDB API, CRUD operations, API for MongoDB and additional quick starts

Posted on by

Azure Cosmos DB is a globally distributed system that supports the document, graph, and key-value data models which Microsoft have classified as a multi-model database service for mission-critical systems.

It also supports both the API for MongoDB and the DocumentDB API for creating, querying, and managing resources.

If you would like to understand how to answer any of the following questions: –

  • How do the standard HTTP methods work with Azure Cosmos DB resources?
  • How do I create a new resource using POST?
  • How do I register a stored procedure using POST?
  • How does Azure Cosmos DB support concurrency control?
  • What are the connectivity options for HTTPS and TCP?

Interaction model using the standard HTTP methods

Then take a look at Azure Cosmos DB REST API for full details first published on 18th July 2017 which covers these topics.

If interested in performing CRUD operations using REST, see Common tasks using the Azure Cosmos DB REST API.

If interested in performing CRUD operations using C# and REST, see the REST from .NET Sample on GitHub which can help you out.

If interested in more details of the MongoDB API, then see Introduction to Azure Cosmos DB: API for MongoDB which covers the benefits of using Azure Cosmos DB for MongoDB applications.
