Pub Version

MSAL.js for Dart #

A Dart wrapper for the Microsoft Authentication Library for JavaScript (MSAL.js).

Contents #

Install msal.js #

This package does not come with msal.js. Please refer to the msal.js documentation for installation.

See the msal.js support table below to determine which version of msal.js should be used with each version of this package.

Usage #

For more complete usage information, see this example.

For usage in a Flutter Web app, see the Flutter Web example.

Also see the msal.js documentation. Class, function, and parameter names are almost all the same between this wrapper and msal.js (please see "Differences from msal.js" for more information). Following msal.js examples should be mostly straight-forward.

Short getting started example:

import 'package:msal_js/msal_js.dart';

void main() {
  // Important note about the below 'options' objects:
  // To set an option to `undefined`, simply don't call
  // the setter for that option at all. This will let
  // msal.js use the option's default value. Setting an
  // option to `null` will not use its default value.

  // Create an MSAL logger (optional)
  var logger = new Logger(_loggerCallback,
    new LoggerOptions()
      ..level = LogLevel.verbose // log everything

  // Configure and create an MSAL authentication context
  // Note: Only clientId is required
  var config = new Configuration()
    ..auth = (new AuthOptions()
      ..clientId = 'your_client_id'

  var userAgentApplication = new UserAgentApplication(config);

  // If you plan on using the redirect flow, register a callback

  // Login by calling either:
  // - userAgentApplication.loginRedirect
  // - userAgentApplication.loginPopup

  // After login, acquire an access token by calling:
  // userAgentApplication.acquireTokenSilent

  // If acquiring the token silently fails, use either:
  // - userAgentApplication.acquireTokenRedirect
  // - userAgentApplication.acquireTokenPopup

  // See the msal.js documentation for more information.

void _loggerCallback(LogLevel level, String message, bool containsPii) {
  print('[$level] $message');

void _authCallback(AuthException error, [AuthResponse response]) {
  // ...

Differences from msal.js #

This package has a few minor differences from the JavaScript and TypeScript APIs in msal.js. These are mainly due to incompatibilities between TypeScript and Dart and quality-of-life differences to provide a more idiomatic Dart API.

  • APIs returning JavaScript Promises instead return Dart Futures.
  • TypeScript string unions (such as cacheLocation) are represented as Dart enums.
  • MSAL errors are represented as Dart exceptions and use the suffix Exception instead of Error (e.g. AuthError in msal.js is AuthException in this wrapper).
  • Typescript interfaces are represented as a full Dart type. Instead of passing a map which meets the interface requirements, an actual type must be constructed (e.g. instead of loginPopup({scopes: []}) you would do loginPopup(new AuthRequest()..scopes = [])).

msal.js Support Table #

Each package version (on the left) specifies which version of msal.js it supports (on the right). Only changes in support are added to this table.

If the package version you are looking for is not listed, use the row corresponding to the next listed version going down. For example, the package version 0.3.0 is not listed, so the version of msal.js that 0.3.0 supports is 0.2.3 since the next package entry down is 0.2.0 (which supports msal.js 0.2.3).
