@azure/identity-broker v1.0.0

Azure Identity plugin for brokered authentication

This package provides a plugin to the Azure Identity library for JavaScript (@azure/identity) that enables using an authentication broker such as WAM.

Source code | Samples

Getting started

import { nativeBrokerPlugin } from "@azure/identity-broker";
import { useIdentityPlugin } from "@azure/identity";

useIdentityPlugin(nativeBrokerPlugin);

Prerequisites

• An Azure subscription.

Install the package

This package is designed to be used with Azure Identity for JavaScript. Install both @azure/identity and this package using npm:

npm install --save @azure/identity
npm install --save @azure/identity-broker

Supported environments

Azure Identity plugins for JavaScript support stable (even numbered) versions of Node.js starting from v18. While the plugins may run in other Node.js versions, no support is guaranteed. @azure/identity-broker does not support browser environments.

Key concepts

If this is your first time using @azure/identity or Microsoft Entra ID, we recommend that you read Using @azure/identity with Microsoft Entra ID first. This document will give you a deeper understanding of the platform and how to configure your Azure account correctly.

Azure Identity plugins

As of @azure/identity version 2.0.0, the Identity client library for JavaScript includes a plugin API. This package (@azure/identity-broker) exports a plugin object that you must pass as an argument to the top-level useIdentityPlugin function from the @azure/identity package. Enable native broker in your program as follows:

import { nativeBrokerPlugin } from "@azure/identity-broker";
import { useIdentityPlugin, InteractiveBrowserCredential } from "@azure/identity";

useIdentityPlugin(nativeBrokerPlugin);

const credential = new InteractiveBrowserCredential({
  brokerOptions: {
    enabled: true,
    },
  });

After calling useIdentityPlugin, the native broker plugin is registered to the @azure/identity package and will be available on the InteractiveBrowserCredential that supports WAM broker authentication. This credential has brokerOptions in the constructor options.

Examples

Once the plugin is registered, you can enable WAM broker authentication by passing brokerOptions with an enabled property set to true to a credential constructor. In the following example, we use the InteractiveBrowserCredential.

import { nativeBrokerPlugin } from "@azure/identity-broker";
import { useIdentityPlugin, InteractiveBrowserCredential } from "@azure/identity";

useIdentityPlugin(nativeBrokerPlugin);

async function main() {
  const credential = new InteractiveBrowserCredential({
    brokerOptions: {
      enabled: true,
    },
  });

  // We'll use the Microsoft Graph scope as an example
  const scope = "https://graph.microsoft.com/.default";

  // Print out part of the access token
  console.log((await credential.getToken(scope)).token.substr(0, 10), "...");
}

main().catch((error) => {
  console.error("An error occurred:", error);
  process.exit(1);
});

Troubleshooting

Logging

Enabling logging may help uncover useful information about failures. In order to see a log of HTTP requests and responses, set the AZURE_LOG_LEVEL environment variable to info. Alternatively, logging can be enabled at runtime by calling setLogLevel in the @azure/logger:

import { setLogLevel } from ("@azure/logger");

setLogLevel("info");
