Angel3 Client #




A browser, mobile and command line based client that supports querying Angel3 backend.
Usage #
// Choose one or the other, depending on platform
import 'package:angel3_client/io.dart';
import 'package:angel3_client/browser.dart';
import 'package:angel3_client/flutter.dart';

main() async {
Angel app = Rest("http://localhost:3000");
}

You can call service to receive an instance of Service, which acts as a client to a service on the server at the given path (say that five times fast!).
foo() async {
Service Todos = app.service("todos");
List<Map> todos = await Todos.index();

print(todos.length);
}

The CLI client also supports reflection via package:belatuk_json_serializer. There is no need to work with Maps; you can use the same class on the client and the server.
class Todo extends Model {
String text;

Todo({String this.text});
}

bar() async {
// By the next release, this will just be:
// app.service<Todo>("todos")
Service Todos = app.service("todos", type: Todo);
List<Todo> todos = await Todos.index();

print(todos.length);
}

Just like on the server, services support index, read, create, modify, update and remove.
Authentication #
Local auth:
var auth = await app.authenticate(type: 'local', credentials: {username: ..., password: ...});
print(auth.token);
print(auth.data); // User object

Revive an existing jwt:
Future<AngelAuthResult> reviveJwt(String jwt) {
return app.authenticate(credentials: {'token': jwt});
}
copied to clipboard
Via Popup:
app.authenticateViaPopup('/auth/google').listen((jwt) {
// Do something with the JWT
});
copied to clipboard
Resume a session from localStorage (browser only):
// Automatically checks for JSON-encoded 'token' in localStorage,
// and tries to revive it
await app.authenticate();

Logout:
await app.logout();

Live Updates #
Oftentimes, you will want to update a collection based on updates from a service. Use ServiceList for this case:
build(BuildContext context) async {
var list = ServiceList(app.service('api/todos'));

return StreamBuilder(
stream: list.onChange,
builder: _yourBuildFunction,
);
}
