Microsoft Graph JavaScript Client Library

npm version badge Travis

The Microsoft Graph JavaScript client library is a lightweight wrapper around the Microsoft Graph API that supports both Node and the browser. See the samples folder for code examples. You can also use our TypeScript graph types with this library. We love your feedback! You can file an issue in this repository or write on our UserVoice page.

Installation

Node

You can find installation instructions at the Node.js website.

npm install @microsoft/microsoft-graph-client

Include the library in your JavaScript file with const MicrosoftGraph = require("@microsoft/microsoft-graph-client");

Browser

Include lib/graph-js-sdk-web.js in your page.

<script type="text/javascript" src="graph-js-sdk-web.js"></script>

Usage

Initialize client with access token provider

This client library only handles authentication in the most basic way possible. The application is responsible for refreshing tokens and returning an immediately valid access token in the authentication provider.

 
var client = MicrosoftGraph.Client.init({
    authProvider: (done) => {
        done(null, "PassInAccessTokenHere"); //first parameter takes an error if you can't get an access token
    }
});
 

Calling pattern

All calls to Microsoft Graph are chained together starting with client.api(path). Path supports the following formats:

For more examples of accepted paths, see the test cases.

// Example calling /me with no parameters
client
    .api('/me')
    .get((err, res) => {
        console.log(res); // prints info about authenticated user
    });

Calls should start with .api(), then chain query parameters and end with an action.

// get the names of my top 5 contacts on the beta endpoint
client
    .api('me/people')
    .version("beta") //optional, but recommeded to have before query params
    .top(5)
    .select("displayName")
    .get((err, res) => {
        const topContacts = res.value.map((u) => {return u.displayName});    
        console.log("Your top contacts are", topContacts.join(""));
    });

The actions(.get(), .put(), etc.) accept a callback or don't pass in a function to get back a Promise.

client
    .api('/me')
    .select("displayName")
    .get()
    .then((res) => {
        console.log(res);
    }).catch((err) => {
        console.log(err);
    });

Actions

.post() and .patch()

The first parameter of .post() and .patch() takes an object that will be sent as the content of the request.

// construct the 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"
    }
}
 
client
    .api('/users/me/sendMail')
    .post({message: mail}, (err, res) => {
        console.log(res)
    })

.del() and .delete()

// delete a OneDrive item
client
    .api(`/me/drive/items/${ONE_DRIVE_FILE_ID_TO_DELETE}`)
    .delete((err, res) => {
        if (err) {
            console.log(err)
            return;
        }
        console.log(res)
    })
 

.put() and .putStream()

You can upload files to the graph using .put(). For example, this can be used to update a profile picture from an HTML input form. See the browser sample for complete code.

var file = document.querySelector('input[type=file]').files[0];
 
client
    .api('/me/photo/$value')
    .put(file, (err, res) => {
        if (err) {
            console.log(err);
            return;
        }
        console.log("We've updated your picture!");
    });

Use .putStream() to upload files to Microsoft Graph with Node.js streams.

 
// Upload a file to OneDrive
let fs = require('fs'); // requires filesystem module
let stream = fs.createReadStream('./logo.png'); //path to local file
client
    .api('/me/drive/root/children/logo.png/content') // path to the destination in OneDrive
    .put(stream, (err) => {
        console.log(err);
    });

.getStream()

Use .getStream() to stream a download from Microsoft Graph.

const fs = require('fs'); // requires filesystem module
client
    .api('/me/drive/root/children/Book.xlsx/content') // path of  source file in OneDrive
    .getStream((err, downloadStream) => {
        let writeStream = fs.createWriteStream('Book.xlsx'); // path to save file to
        downloadStream.pipe(writeStream).on('error', console.log);
    });

Query Parameters

$select, $expand and $orderby

These methods can take a string property, an array of strings or you can pass in each value as a separate argument.

.select("birthday")
.select("department")
// same as
.select("birthday", "department")
// same as
.select(["birthday", "department"])
client
    .api('/me/people')
    .select(["displayName", "department", "title"])
    .get((err, res) => {
        console.log(res)
    })

$top and $skip

These parameters only take a number. Calling them multiple times is not supported.

.top(5)
.skip(10)

$count

Set .count() to true to also return the number of objects in the collection.

.count(true)

$filter

Pass a filter string to .filter() for filtering result collections. Calling filter multiple times will override previous filter strings.

client
    .api("/users")
    .filter("startswith(displayName, 'david')")
    .get((err, res) => {
        console.log(res)
    })

Other API methods

.version()

Passing in a version through .version() has the highest priority. It overrides the Microsoft Graph client default version from .init() and the global library default (currently v1.0).

.query()

You can pass in any URL query parameters as a dictionary or string.

.query({"$select":"displayName"})
// same as 
.query("$select=displayName")
// same as
.select("displayName")
 

.header() and .headers()

You can pass in additional request headers, either individually or in a dictionary.

.header("someHeaderName", "someHeaderValue")
// or
.headers({"someHeaderName":"someHeaderValue"})
 

.responseType()

To set a custom response type, use the .responseType(string) method. To see an example, check the browser sample that downloads an image and displays it in an <img> element.

Additional information

Options in MicrosoftGraph.Client.init()

The following are optional parameters to pass to MicrosoftGraph.Client.init(), except for the authProvider:

  • defaultVersion - When .version() isn't called, this version is used. (defaults to v1.0)
  • debugLogging - Set to true to see the URL of the request printed.
  • authProvider - See the usage section for info.
  • baseUrl - If you need to call a different URL instead of graph.microsoft.io, specify it as a string here.

Full service response

The full response containing the headers, status code, and body can be obtained by passing a third parameter to the callback.

client
    .api('/me')
    .select("displayName")
    .get((err, res, rawResponse) => {
        console.log(rawResponse.statusCode);
        console.log(rawResponse.header);
    });

Native date objects can be passed in as parameters

var date = new Date();
date.setDate(date.getDate()-365); // ~ 1 year ago
 
client
    .api('/me')
    .body({"birthday": date})
    .update((err, res) => {
        console.log("Updated my birthday")
    })

Development

These steps are not required to use this library.

npm install installs development dependencies (TypeScript, Mocha, etc.).

Note: If you want to run tsc from the command line, install TypeScript globally with npm install -g typescript or reference ./node_modules/.bin/tsc

npm run build generates lib/ files for node and browser versions.

npm pack bundles the npm module.

npm test runs tests of the core library (URL parsing, mock responses, etc)

npm run test:types to run tests against the Graph API for users, groups, Excel, OneNote, etc.

To build only browser version:

node node-browserify.js > lib/graph-js-sdk-web.js
