# angel_auth
[![Pub](https://img.shields.io/pub/v/angel_auth.svg)](https://pub.dartlang.org/packages/angel_auth)
[![build status](https://travis-ci.org/angel-dart/auth.svg?branch=master)](https://travis-ci.org/angel-dart/auth)
A complete authentication plugin for Angel. Inspired by Passport.
# Wiki
[Click here](https://github.com/angel-dart/auth/wiki).
# Bundled Strategies
* Local (with and without Basic Auth)
* Find other strategies (Twitter, Google, OAuth2, etc.) on Pub!!!
# Example
Ensure you have read the [wiki](https://github.com/angel-dart/auth/wiki).
```dart
configureServer(Angel app) async {
var auth = AngelAuth<User>();
auth.serializer = ...;
auth.deserializer = ...;
auth.strategies['local'] = LocalAuthStrategy(...);
// POST route to handle username+password
app.post('/local', auth.authenticate('local'));
// Using Angel's asynchronous injections, we can parse the JWT
// on demand. It won't be parsed until we check.
app.get('/profile', ioc((User user) {
print(user.description);
}));
// 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);
}
```
# Default Authentication Callback
A frequent use case within SPA's is opening OAuth login endpoints in a separate window.
[`angel_client`](https://github.com/angel-dart/client)
provides a facility for this, which works perfectly with the default callback provided
in this package.
```dart
configureServer(Angel app) async {
var handler = auth.authenticate(
'facebook',
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](https://github.com/angel-dart/client#authentication):
```dart
app.authenticateViaPopup('/auth/google').listen((jwt) {
// Do something with the JWT
});
```
