azure-graphapi

Node.js package for making Azure Active Directory Graph API calls

v0.1.0

Installation

npm install azure-graphapi --save

Usage

var GraphAPI = require('azure-graphapi');
 
var graph = new GraphAPI(tenant, clientId, clientSecret);
// The tenant, clientId, and clientSecret are usually in a configuration file. 
 
graph.get('users/a8272675-dc21-4ff4-bc8d-8647830fa7db', function(err, user) {
    if (!err) {
        console.dir(user);
    }
}

Details

This package provides an HTTPS interface to the Azure Active Directory Graph API. You will need the tenant (i.e., domain) of your Azure AD instance as well as an application within that AD instance that has permissions to access your directory. This application is identified by a clientId and authenticated using a clientSecret. The clientSecret is also called the application key.

The typical verbs are supported (GET, POST, PUT, PATCH, and DELETE). The getObjects method is useful for reading a large number of objects. Azure AD limits each response to 100 objects. The getObject method follows the odata.nextLink and accumulates all objects of a specific object type.

Interface

This section describes the constructor returned by this module and the available instance methodss.

Constructor

GraphAPI(tenant, clientId, clientSecret, [apiVersion])

Creates a new GraphAPI instance. If the apiVersion is not specified, it defaults to version 1.6.

var GraphAPI = require('azure-graphapi');
 
var graph = new GraphAPI(tenant, clientId, clientSecret);

Methods

Each of these methods takes ref parameter with optional replacement args. These are passed to strformat to create the actual URI reference. This allows for the following constructs:

var person = {
    userId: 'a8272675-dc21-4ff4-bc8d-8647830fa7db'
};
 
graph.get('users/{0}', person.userId, function(err, user) {
    if (!err) {
        console.dir(user);
    }
}

The following REST-style URI reference is also available:

var person = {
    userId: 'a8272675-dc21-4ff4-bc8d-8647830fa7db'
};
 
graph.get('users/{userId}', person, function(err, user) {
    if (!err) {
        console.dir(user);
    }
}

In all cases, do not prefix the ref with a forward slash and do not add the API version as this is added automatically based on the API version specified in the constructor.

graph.get(ref [,args...], callback)

Performs an HTTPS GET request. The callback signature is callback(err, response).

graph.post(ref [,args...], data, contentType, callback)

Performs an HTTPS POST request. The callback signature is callback(err, response).

graph.put(ref [,args...], data, contentType, callback)

Performs an HTTPS PUT request. The callback signature is callback(err, response).

graph.patch(ref [,args...], data, contentType, callback)

Performs an HTTPS PATCH request. The callback signature is callback(err, response).

graph.delete(ref [,args...], callback)

Performs an HTTPS DELETE request. The callback signature is callback(err).

graph.getObjects(ref [,args...], objectType, callback)

Performs an HTTPS GET request and accumulates all objects having the specified objectType (e.g., "User"). The callback signature is callback(err, objects). This method follows the odata.nextLink property in the response and continues until no more batches of objects are available.

Notes

  1. The HTTPS request logic parses out the error_description and odata.error messages from JSON responses to unsuccessful requests. These become part of the error message in the err object provided to the callback method.
  2. If the contentType is null and the request data is a string, it is assumed to be form data and is sent as application/x-www-form-urlencoded.
  3. If the contentType is null and the request data is a JavaScript object, it is send as application/json.
  4. The callback is passed only one argument (err) if the response status code is 204 (No Content). This is important when using libraries such as the async utilities.
  5. If the response has a value property, it is that value that is passed to the callback function and not the entire response object.
