Microsoft Graph JavaScript Client Library

npm version badge Known Vulnerabilities Licence code style: prettier Downloads

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 v1.0 and beta!!

TypeScript demo

Node version requirement

Node.js 12 LTS or higher. The active Long Term Service (LTS) version of Node.js is used for on-going testing of existing and upcoming product features.

For Node.js 18 users, it is recommended to disable the experimental fetch feature by supplying the --no-experimental-fetch command-line flag while using the Microsoft Graph JavaScript client library.


Via npm

npm install @microsoft/microsoft-graph-client

import @microsoft/microsoft-graph-client into your module.

Also, you will need to import any fetch polyfill which suits your requirements. Following are some fetch polyfills -

import "isomorphic-fetch"; // or import the fetch polyfill you installed
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/polyfill@7.4.4/dist/polyfill.min.js"></script>

Getting started

1. Register your application

To call Microsoft Graph, your app must acquire an access token from the Microsoft identity platform. Learn more about this -

2. Create a Client Instance

The Microsoft Graph client is designed to make it simple to make calls to Microsoft Graph. You can use a single client instance for the lifetime of the application.

For information on how to create a client instance, see Creating Client Instance

3. 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 start with client.api(path) and end with an action.

Example of getting user details:

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

Example of sending an email to the recipients:

// Construct email object
const mail = {
	subject: "Microsoft Graph JavaScript Sample",
	toRecipients: [
			emailAddress: {
				address: "example@example.com",
	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 });
} catch (error) {
	throw error;
