Hasura Connect Package #

Connect your Flutter/Dart apps to Hasura simply.

Install #

Add dependency in your pubspec.yaml file:

dependencies:
  hasura_connect:

or use Slidy:

slidy install hasura_connect

Usage #

A simple usage example:

//import
import 'package:hasura_connect/hasura_connect.dart';

String url = 'http://localhost:8080/v1/graphql';
HasuraConnect hasuraConnect = HasuraConnect(url);

You can encapsulate this instance into a BLoC class or directly into a Provider.

Crie um documento com a Query:

//document
String docQuery = """
  query {
    authors {
        id
        email
        name
      }
  }
""";

Now just add the document to the "query" method of the HasuraConnect instance.

var r = await hasuraConnect.query(docQuery);
print(r);

Subscriptions #

Subscriptions will notify you each time you have a change to the searched items. Use the "hasuraConnect.subscription" method to receive a stream.

Snapshot snap = hasuraConnect.subscription(docSubscription);
  snap.stream.listen((data) {
    print(data);
  }).onError((err) {
    print(err);
  });

Authorization (JWT Token) #

View Hasura's official Authorization documentation.

  String url = 'http://localhost:8080/v1/graphql';
HasuraConnect hasuraConnect = HasuraConnect(url, token: () async {
  //sharedPreferences or other storage logic
  return "Bearer YOUR-JWT-TOKEN";
});

Dispose #

HasuraConnect provides a dispose () method for use in Provider or BlocProvider. Subscription will start only when someone is listening, and when all listeners are closed HasuraConnect automatically disconnects.

Therefore, we only connect to Hasura when we are actually using it;
