Microsoft Graph JavaScript Client Library

The Microsoft Graph JavaScript client library is a lightweight wrapper around the Microsoft Graph API that can be used server-side and in the browser.

Looking for IntelliSense on models (Users, Groups, etc.)? Check out the Microsoft Graph Types repository!

Installation

Via npm

npm install @microsoft/microsoft-graph-client

import @microsoft/microsoft-graph-client into your module and also you will need polyfills for fetch like isomorphic-fetch.

import "isomorphic-fetch";
import { Client } from "@microsoft/microsoft-graph-client";

Via Script Tag

Include graph-js-sdk.js in your HTML page.

<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/@microsoft/microsoft-graph-client/lib/graph-js-sdk.js"></script>

In case your browser doesn't have support for Fetch [support] or Promise [support], you need to use polyfills like github/fetch for fetch and es6-promise for promise.

<!-- polyfilling promise -->
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/es6-promise/dist/es6-promise.auto.min.js"></script>

<!-- polyfilling fetch -->
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/whatwg-fetch/dist/fetch.umd.min.js"></script>

<!-- depending on your browser you might wanna include babel polyfill -->
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/@babel/[email protected]/dist/polyfill.min.js"></script>

Getting started

1. Register your application

Microsoft Application Registration Portal: Register a new application that works with Microsoft Accounts and/or organizational accounts using the unified V2 Authentication Endpoint.
Microsoft Azure Active Directory: Register a new application in your tenant's Active Directory to support work or school users for your tenant or multiple tenants.

2. Authenticate for the Microsoft Graph service

The Microsoft Graph JavaScript Client Library has an adapter implementation (ImplicitMSALAuthenticationProvider) for MSAL (Microsoft Authentication Library) which takes care of getting the accessToken. MSAL library does not ship with this library, user has to include it externally (For including MSAL, refer this).

Important Note: MSAL is supported only for frontend applications, for server-side authentication you have to implement your own AuthenticationProvider. Learn how you can create a Custom Authentication Provider.

Creating an instance of ImplicitMSALAuthenticationProvider in browser environment

Refer devDependencies in package.json for the compatible msal version and update that version in below.

<script src="https://secure.aadcdn.microsoftonline-p.com/lib/<version>/js/msal.min.js"></script>

// Configuration options for MSAL @see https://github.com/AzureAD/microsoft-authentication-library-for-js/wiki/MSAL.js-1.0.0-api-release#configuration-options
const msalConfig = {
	auth: {
		clientId: "your_client_id", // Client Id of the registered application
		redirectUri: "your_redirect_uri",
	},
};
const graphScopes = ["user.read", "mail.send"]; // An array of graph scopes

// Important Note: This library implements loginPopup and acquireTokenPopup flow, remember this while initializing the msal
// Initialize the MSAL @see https://github.com/AzureAD/microsoft-authentication-library-for-js#1-instantiate-the-useragentapplication
const msalApplication = new Msal.UserAgentApplication(msalConfig);
const options = new MicrosoftGraph.MSALAuthenticationProviderOptions(graphScopes);
const authProvider = new MicrosoftGraph.ImplicitMSALAuthenticationProvider(msalApplication, options);

Creating an instance of ImplicitMSALAuthenticationProvider in node environment

Refer devDependencies in package.json for the compatible msal version and update that version in below.

npm install msal@<version>

import { UserAgentApplication } from "msal";

import { ImplicitMSALAuthenticationProvider } from "@microsoft/microsoft-graph-client/lib/src/ImplicitMSALAuthenticationProvider";
import { MSALAuthenticationProviderOptions } from '@microsoft/microsoft-graph-client/lib/src/MSALAuthenticationProviderOptions';

// An Optional options for initializing the MSAL @see https://github.com/AzureAD/microsoft-authentication-library-for-js/wiki/MSAL-basics#configuration-options
const msalConfig = {
	auth: {
		clientId: "your_client_id", // Client Id of the registered application
		redirectUri: "your_redirect_uri",
	},
};
const graphScopes = ["user.read", "mail.send"]; // An array of graph scopes

// Important Note: This library implements loginPopup and acquireTokenPopup flow, remember this while initializing the msal
// Initialize the MSAL @see https://github.com/AzureAD/microsoft-authentication-library-for-js#1-instantiate-the-useragentapplication
const msalApplication = new UserAgentApplication(msalConfig);
const options = new MSALAuthenticationProviderOptions(graphScopes);
const authProvider = new ImplicitMSALAuthenticationProvider(msalApplication, options);

User can integrate own preferred authentication library by implementing IAuthenticationProvider interface. Refer implementing Custom Authentication Provider.

3. Initialize a Microsoft Graph Client object with an authentication provider

An instance of the Client class handles requests to Microsoft Graph API and processing the responses. To create a new instance of this class, you need to provide an instance of IAuthenticationProvider which needs to be passed as a value for authProvider key in ClientOptions to a static initializer method Client.initWithMiddleware.

For browser environment

const options = {
	authProvider, // An instance created from previous step
};
const Client = MicrosoftGraph.Client;
const client = Client.initWithMiddleware(options);

For node environment

import { Client } from "@microsoft/microsoft-graph-client";

const options = {
	authProvider, // An instance created from previous step
};
const client = Client.initWithMiddleware(options);

For more information on initializing client, refer this document.

4. Make requests to the graph

Once you have authentication setup and an instance of Client, you can begin to make calls to the service. All requests should be start with client.api(path) and end with an action.

Getting user details

try {
	let userDetails = await client.api("/me").get();
	console.log(userDetails);
} catch (error) {
	throw error;
}

Sending an email to the recipients

// Construct email object
const mail = {
	subject: "Microsoft Graph JavaScript Sample",
	toRecipients: [
		{
			emailAddress: {
				address: "[email protected]",
			},
		},
	],
	body: {
		content: "<h1>MicrosoftGraph JavaScript Sample</h1>Check out https://github.com/microsoftgraph/msgraph-sdk-javascript",
		contentType: "html",
	},
};
try {
	let response = await client.api("/me/sendMail").post({ message: mail });
	console.log(response);
} catch (error) {
	throw error;
}
