Create an Angular app with Azure Cosmos DB's API for MongoDB

APPLIES TO: MongoDB

This multi-part tutorial demonstrates how to create a new app written in Node.js with Express and Angular and then connect it to your Azure Cosmos DB account configured with Azure Cosmos DB's API for MongoDB.

Azure Cosmos DB is Microsoft’s fast NoSQL database with open APIs for any scale. It allows you to develop modern apps with SLA-backed speed and availability, automatic and instant scalability, and open source APIs for many NoSQL engines.

This multi-part tutorial covers the following tasks:

• Create a Node.js Express app with the Angular CLI
• Build the UI with Angular
• Create an Azure Cosmos DB account using the Azure CLI
• Use Mongoose to connect to Azure Cosmos DB
• Add Post, Put, and Delete functions to the app

Trying to do capacity planning for a migration to Azure Cosmos DB? You can use information about your existing database cluster for capacity planning.

• If all you know is the number of vcores and servers in your existing database cluster, read about estimating request units using vCores or vCPUs
• If you know typical request rates for your current database workload, read about estimating request units using Azure Cosmos DB capacity planner
