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 documentdb

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.

Traces

The documentdb module support tracing via the debug module. Traces will go to stderr by default. To enable tracing, you can set the DEBUG environment variable in a variety of ways.

• documentdb:* will output all logs. This can be verbose, so it's helpful to filter on log level.
• documentdb:<log level>:* will output all traces for a given <log level> value. The valid levels are error, warn, info, and debug.
• documentdb:<log level>:<component> will output all traces for a given <log level> and <component>. The valid components are request and query.

You can combine filters via ,. So if you wanted to have error info for all components, but only debug info for query, then you'd use documentdb:error:*,documentdb:debug:query.

Tests

Prerequisites

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

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

3. Install mocha package globally

    npm install -g mocha
   

Running the tests

Using your command-line tool, from the root of your local copy of azure-documentdb-node repository: (If you are contributing changes and submitting PR then you need to ensure that you run the tests against your local copy of the source, and not the published npm package.)

1. Remove documentdb, if previously installed

    npm remove documentdb
   

2. Install documentdb

    npm install source
   

3. Change to test directory

    cd source\test
   

4. Run the tests

    mocha -t 0 -R spec
   

If you just want to run the tests against the published npm package then skip steps #1 & #2 proceed directly to step #3

Examples

Hello World using Callbacks via the Core Module

var DocumentClient = require('documentdb').DocumentClient;

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

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

client.createDatabase(databaseDefinition, function(err, database) {
    if(err) return console.log(err);
    console.log('created db');

    client.createCollection(database._self, collectionDefinition, function(err, collection) {
        if(err) return console.log(err);
        console.log('created collection');

        client.createDocument(collection._self, documentDefinition, function(err, document) {
            if(err) return console.log(err);
            console.log('Created Document with content: ', document.content);

            cleanup(client, database);
        });
    });
});

function cleanup(client, database) {
    client.deleteDatabase(database._self, function(err) {
        if(err) console.log(err);
    })
}
