[![TypeScript demo](https://raw.githubusercontent.com/microsoftgraph/msgraph-sdk-javascript/master/types-demo.PNG)](https://github.com/microsoftgraph/msgraph-typescript-typings)

## 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.

## Installation

### Via npm

```cmd
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 -

-   [isomorphic-fetch](https://www.npmjs.com/package/isomorphic-fetch).
-   [cross-fetch](https://www.npmjs.com/package/cross-fetch)
-   [whatwg-fetch](https://www.npmjs.com/package/whatwg-fetch)

```typescript
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](https://cdn.jsdelivr.net/npm/@microsoft/microsoft-graph-client/lib/graph-js-sdk.js) in your HTML page.

```HTML
<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](https://developer.mozilla.org/docs/Web/API/Fetch_API) [[support](https://developer.mozilla.org/docs/Web/API/Fetch_API#Browser_compatibility)] or [Promise](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise) [[support](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise#Browser_compatibility)], you need to use polyfills like [github/fetch](https://github.com/github/fetch) for fetch and [es6-promise](https://github.com/stefanpenner/es6-promise) for promise.

```HTML
<!-- 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 -

-   [Authentication and authorization basics for Microsoft Graph](https://docs.microsoft.com/graph/auth/auth-concepts)
-   [Register your app with the Microsoft identity platform](https://docs.microsoft.com/graph/auth-register-app-v2)

### 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](./docs/CreatingClientInstance.md)

### 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](./docs/Actions.md).

Example of getting user details:

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

Example of sending an email to the recipients:

```typescript
// 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 });
	console.log(response);
} catch (error) {
	throw error;
}
```

For more information, refer: [Calling Pattern](docs/CallingPattern.md), [Actions](docs/Actions.md), [Query Params](docs/QueryParameters.md), [API Methods](docs/OtherAPIs.md) and [more](docs/).

-   [TokenCredentialAuthenticationProvider Samples](samples/)

The Microsoft Graph JavaScript SDK provides a `LargeFileUploadTask` to upload large files to OneDrive, Outlook and Print API:

-   [LargeFileUploadTask documentation](docs/tasks/LargeFileUploadTask.md)
-   [Samples using `LargeFileUploadTask` and `OneDriveLargeFileTask`](samples/) The following `MSAL` samples provide information on authentication using `MSAL` libraries and how to use the Microsoft Graph JavaScript SDK client with MSAL as a custom authentication provider to query the Graph API:
