Capacitor MSAL Plugin

This is an OAuth 2 client plugin for Capacitor. It uses the Microsoft Authentication Library (MSAL) to authenticate the user and acquire access tokens.

Installing

npm install capacitor-msal

Configuration

The capacitor-msal plugin needs to be imported into your application to register the plugin with Capacitor. In your app's entry point (such as main.ts in Angular applications), add the following line:

import 'capacitor-msal';

Once imported, the plugin needs to be initialized with app-specific values. In your initialization logic (such as APP_INTIALIZER in Angular), call the Msal.init() method. For example:

import { Plugins } from '@capacitor/core';
const { Msal } = Plugins;

await Msal.init({
	auth: {
		clientId: 'YOUR_CLIENT_ID'
	}
});

The init method accepts all configuration options from MSAL.js. Note that some options may not be supported on all platforms. The only required parameter is clientId.

Web

The Web platform is implemented as a passthrough to MSAL.js. No extra configuration is needed.

Electron

Once this plugin has been installed in your application, the Electron implementation needs to be installed into your Electron app as a dependency. Assuming your Electron app is one level below your root package.json, use the following command.

npm install ../node_modules/capacitor-msal/capacitor-msal-electron-<version>.tgz

The Electron plugin uses the native module keytar to securely store user refresh tokens. You will need a module that rebuilds native dependencies, such as electron-rebuild or electron-builder.

Next, the Electron implementation needs to be imported into your application as a preload script. This implementation is exported as ES Modules. The esm package is recommended to import this module.

Create a script (e.g. preload.js) with the following content.

require = require('esm')(module, {
	mainFields: ['module']
});

require('@capacitor/electron/dist/electron-bridge');
require('capacitor-msal-electron');

This will run in the renderer process to add Msal to the Capacitor Plugins proxy.

Add the newly created script to the main window as a preload script. For example,

mainWindow = new BrowserWindow({
	height: 920,
	width: 1600,
	show: false,
	webPreferences: {
		nodeIntegration: true,
		preload: path.join(__dirname, 'preload.js')
	}
});

Finally, the plugin needs to be added to the main process. A custom logger can be used to capture debug information from the plugin. The module electron-log is recommended.

const logger = require('electron-log');
const { CapacitorMsal } = require('capacitor-msal-electron');

const msal = new CapacitorMsal(logger);
msal.init();

The configuration file capacitor.config.json is required to use this plugin. The appId specified in this file will be used as the storage key for refresh tokens. Additionally,auth configuration options can be specified in this file. Options specified here will override the options specified in the init method. For example:

{
	"appId": "YOUR_APP_ID",
	"plugins": {
		"Msal": {
			"redirectUri": "https://login.microsoftonline.com/common/oauth2/nativeclient"
		}
	}
}

Proxy Settings

This plugin internally uses electron-fetch to access the token endpoint, and an Electron BrowserWindow is used to access the authorize endpoint. Both of these components use Chromium and its underlying network operations. As a result, this plugin will automatically use system-wide proxy settings without any additional configuration.
