angel_auth

Pub build status

A complete authentication plugin for Angel. Inspired by Passport.

Bundled Strategies

  • Local (with and without Basic Auth)
  • Find other strategies (Twitter, Google, OAuth2, etc.) on Pub!!!

Example

Ensure you have read the wiki.

configureServer(Angel app) async {
  var auth = new AngelAuth();
  auth.serializer = ...;
  auth.deserializer = ...;
  auth.strategies['local'] = new LocalAuthStrategy(...);
  
  // POST route to handle username+password
  app.post('/local', auth.authenticate('local'));
  
  // Use a comma to try multiple strategies!!!
  //
  // Each strategy is run sequentially. If one succeeds, the loop ends.
  // Authentication failures will just cause the loop to continue.
  // 
  // If the last strategy throws an authentication failure, then
  // a `401 Not Authenticated` is thrown.
  var chainedHandler = auth.authenticate(
    ['basic','facebook'],
    authOptions
  );
  
  // Apply angel_auth-specific configuration
  await app.configure(auth.configureServer);
  
  // Middleware to decode JWT's...
  app.use(auth.decodeJwt);
}

Default Authentication Callback

A frequent use case within SPA's is opening OAuth login endpoints in a separate window. angel_client provides a facility for this, which works perfectly with the default callback provided in this package.

configureServer(Angel app) async {
  var handler = auth.authenticate(
    'facebook',
    new AngelAuthOptions(callback: confirmPopupAuthentication()));
  app.get('/auth/facebook', handler);
  
  // Use a comma to try multiple strategies!!!
  //
  // Each strategy is run sequentially. If one succeeds, the loop ends.
  // Authentication failures will just cause the loop to continue.
  // 
  // If the last strategy throws an authentication failure, then
  // a `401 Not Authenticated` is thrown.
  var chainedHandler = auth.authenticate(
    ['basic','facebook'],
    authOptions
  );
}

This renders a simple HTML page that fires the user's JWT as a token event in window.opener. angel_client exposes this as a Stream:

app.authenticateViaPopup('/auth/google').listen((jwt) {
  // Do something with the JWT
});

2.0.1

  • Add generic parameter to options on AuthStrategy.authenticate.

import 'dart:async';
import 'package:angel_auth/angel_auth.dart';
import 'package:angel_framework/angel_framework.dart';

main() async {
  var app = new Angel();
  var auth = new AngelAuth<User>();

  auth.serializer = (user) => user.id;

  auth.deserializer = (id) => fetchAUserByIdSomehow(id);

  // Middleware to decode JWT's and inject a user object...
  app.fallback(auth.decodeJwt);

  auth.strategies['local'] = new LocalAuthStrategy((username, password) {
    // Retrieve a user somehow...
    // If authentication succeeds, return a User object.
    //
    // Otherwise, return `null`.
  });

  app.post('/auth/local', auth.authenticate('local'));

  var http = new AngelHttp(app);
  await http.startServer('127.0.0.1', 3000);

  print('Listening at http://127.0.0.1:3000');

  String id, username, password;

Future<User> fetchAUserByIdSomehow(id) async {
  // Fetch a user somehow...
