Installation

Prerequisites

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

Node SDK can be consumed in two ways.

Install Core Module Published to NPM

The core module uses the callbacks model for responses, exposed through the DocumentClient

npm install @azure/cosmos

Install Core Module From Github

1. Clone Azure/azure-documentdb-node repository Please clone the source and tests from https://github.com/Azure/azure-documentdb-node

2. Install documentdb

    npm install azure-documentdb-node\source
   

Prerequisites

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.

Tests

Prerequisites

1. Clone Azure/azure-cosmos-js repository

git clone https://github.com/azure/azure-cosmos-js.git

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

3. Cosmos DB emulator

   • Note: requires a windows machine or ability to run Windows container

4. Install dependencies

   npm i     # alias for npm install
   

5. Build the source

   npm run build   # compiles the typescript source, runs linting, creates webpack, creates docs
   

Running the tests

npm run test    # runs all tests

Examples

Hello World

import { CosmosClient } from "@azure/cosmos"

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

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

async function helloCosmos() {
    await client.createDatabase(databaseDefinition);
    console.log('created db');

    await client.createCollection(database._self, collectionDefinition);
    console.log('created collection');

    await client.createDocument(collection._self, documentDefinition);
    console.log('Created Document with content: ', document.content);

    await client.deleteDatabase(database._self);
    console.log("Deleted database");
});

helloCosmos().finally(()=>{});
