JavaScript and Node.js library for Azure Cosmos DB

Microsoft Azure Cosmos JavaScript SDK

This project provides JavaScript & Node.js SDK library for SQL API of Azure Cosmos Database Service. This project also includes samples, tools, and utilities.

// JavaScript
const cosmos = require('@azure/cosmos');
const CosmosClient = cosmos.CosmosClient;

const endpoint = "[hostendpoint]";                 // Add your endpoint
const masterKey = "[database account masterkey]";  // Add the masterkey of the endpoint
const client = new CosmosClient({ endpoint, auth: { masterKey } });

const databaseDefinition = { id: 'sample database' };
const collectionDefinition = { id: 'sample collection' };
const documentDefinition = { id: 'hello world doc', content: 'Hello World!' };

async function helloCosmos() {
  const { database: db } = await client.databases.create(databaseDefinition);
  console.log('created db');

  const { container } = await db.containers.create(collectionDefinition);
  console.log('created collection');

  const { body } = await container.items.create(documentDefinition);
  console.log('Created item with content: ', body.content);

  await db.delete();
  console.log('Deleted database');
}

helloCosmos().catch(err => {
  console.error(err);
});

Installation

Prerequisites

Install Node.js 6 or above and npm https://docs.npmjs.com/getting-started/installing-node

The SDK is not supported in Node v4 or below. Those Node.js versions are out of support and not recommended for production. Our support will only cover maintained versions of Node.js.

To use the SDK, first create an account and follow tutorial.

Note:

When connecting to the emulator from the SDK, SSL verification is disabled.

Follow these instructions to run the tests locally.

Install

npm install @azure/cosmos
