Pusher HTTP Dart Library #

Build Status (https://pub.dartlang.org/packages/pusher_http_dart)

The Dart library for interacting with the Pusher HTTP API.

This package lets you trigger events to your client and query the state of your Pusher channels. When used with a server, you can authenticate private- or presence-channels.

In order to use this library, you need to have a free account on http://pusher.com. After registering, you will need the application credentials for your app.

Getting Started #

import 'package:pusher_http_dart/pusher.dart';

main() async {
  Pusher pusher = new Pusher('PUSHER_APP_ID','PUSHER_APP_KEY','PUSHER_APP_SECRET');
  Map data = {'message':'Hello world'};
  Response response = await pusher.trigger(['test_channel'],'my_event',data);

Configuration #

There easiest way to configure the library is by creating a new Pusher instance:

Pusher pusher = new Pusher(

Additional options #

PusherOptions options = new PusherOptions(encrypted: true);
Pusher pusher = new Pusher(

Usage #

Triggering events #

It is possible to trigger an event on one or more channels. Channel names can contain only characters which are alphanumeric, _ or `-``. Event name can be at most 200 characters long too.

 Response response = await pusher.trigger(['test_channel'],'my_event',data);

Authenticating Channels #

Pusher provides a mechanism for authenticating a user's access to a channel at the point of subscription.

This can be used both to restrict access to private channels, and in the case of presence channels notify subscribers of who else is also subscribed via presence events.

This library provides a mechanism for generating an authentication signature to send back to the client and authorize them.

For more information see docs.

Private channels

 String socketId = '74124.3251944';
 String auth = pusher.authenticate('test_channel',socketId);

Authenticating presence channels

Using presence channels is similar to private channels, but in order to identify a user, clients are sent a user_id and, optionally, custom data.

 String socketId = '74124.3251944';
 User user = new User('1',{'name':'Adao'});
 String auth = pusher.authenticate('presence-test_channel',socketId,user);

It is possible to query the state of your Pusher application using the generic pusher.get( resource ) method and overloads.

For full details see: http://pusher.com/docs/rest_api

Application state #

This library allows you to query our API to retrieve information about your application's channels, their individual properties, and, for presence-channels, the users currently subscribed to them.

List channels

You can get a list of channels that are present within your application:

Response result = await pusher.get("/channels");

You can provide additional parameters to filter the list of channels that is returned.

Response result = await pusher.get("/channels", { "filter_by_prefix" : "presence-" } );

Fetch channel information

Retrive information about a single channel:

Response result = await pusher.get("/channels/my_channel");

Fetch a list of users on a presence channel

Retrive a list of users that are on a presence channel:

Response result = await pusher.get('/channels/presence-channel/users');
