kabelwerk 0.1.0

The Kabelwerk SDK for Dart.

Kabelwerk

This is the Kabelwerk SDK for Dart.

Installation

Add kabelwerk as a dependency in your pubspec.yaml.

Usage

Connection

The entry point is to create and configure an instance of the Kabelwerk class, which opens and maintains the websocket connection to the Kabelwerk backend.

final kabelwerk = Kabelwerk();

kabelwerk.config(url: url, token: token);

kabelwerk.on('ready', (KabelwerkReady event) {
  // this event is fired once when the initial connection is established
  final inbox = kabelwerk.openInbox();
  final room = kabelwerk.openRoom();
});

kabelwerk.on('error', (ErrorEvent event) {
  // e.g. when the token is invalid
});

kabelwerk.connect();

A Kabelwerk instance takes care of automatically re-connecting when the connection drops, opening inboxes and rooms (see below), retrieving and updating user info.

Read more about the Kabelwerk class in the docs.

Inboxes

An inbox is a view on the rooms the user has access to; it maintains a list of rooms ordered by recency of their latest message.

final inbox = kabelwerk.openInbox();

inbox.on('ready', (InboxReady event) {
  // this event is fired once when the initial list of inbox items is loaded
});

inbox.on('updated', (InboxUpdated event) {
  // whenever a new message is posted, the list of inbox items is updated
  // accordingly and this event is fired
});

inbox.connect();

Rooms

A room object handles posting and retrieving messages in a chat room.

final room = kabelwerk.openRoom(roomId);

room.on('ready', (RoomReady event) {
  // this event is fired once when the room is loaded
});

room.on('message_posted', (MessagePosted event) {
  // this event is fired every time a new message is posted in this room
});

room.connect();

room.postMessage(text: text).then((message) {
  // you will also get the same message via the `message_posted` event
});

You can open as many rooms as you need. However, if you just want to listen for newly posted messages, then it is simpler to leverage the InboxUpdated event.
