CosmosDB API

Getting started

To get started and use this API, you first have to create a CosmosDB account in the Azure portal. Once this is done, just copy this example to get started:

// Your AccountName, this is part of your endpoint 
// (Example: https://my-cosmosdb-account.documents.azure.com" gives "my-cosmosdb-account" as AccountName)
const accountName = "my-cosmosdb-account";

// Find this in the Azure Portal under Keys for your CosmosDB Resource
const primaryKey = '<yourPrimaryKey>'; 

// Initialize the library and connection
const API = require('./CosmosDB')(accountName, primaryKey);

// An example API call
let database = await API.database.createIfNotExists(databaseName);
