Azure Active Directory modules for Node.js

2025-10-08

Overview

Important

Use Microsoft Graph instead of Azure AD Graph API to access Azure Active Directory resources. Our development efforts are now concentrated on Microsoft Graph and no further enhancements are planned for Azure AD Graph API. For more information, see Migrate Azure AD Graph apps to Microsoft Graph.

The Azure Active Directory Authentication Library (ADAL) for Node.js enables Node.js applications to authenticate to Azure AD in order to access AAD protected web resources.

Client package

Install the npm modules

Use npm to install the Azure storage client or management modules.

npm install adal-node

Example

This example from the client credentials sample illustrates server-to-server authentication via client credentials.

const adal = require('adal-node').AuthenticationContext;

const authorityHostUrl = 'https://login.windows.net';
const tenant = 'your-tenant-id';
const authorityUrl = authorityHostUrl + '/' + tenant;
const clientId = 'your-client-id';
const clientSecret = 'your-client-secret';
const resource = 'your-app-id-uri';

const context = new adal(authorityUrl);

context.acquireTokenWithClientCredentials(
  resource,
  clientId,
  clientSecret,
  (err, tokenResponse) => {
    if (err) {
      console.log(`Token generation failed due to ${err}`);
    } else {
      console.dir(tokenResponse, { depth: null, colors: true });
    }
  }
);
