Message Channel

Get Start

• Add it in your root build.gradle at the end of repositories:

  allprojects {
      repositories {
        ...
        maven { url 'https://jitpack.io' }
      }
  }

• Add the dependency:

  dependencies {
  }

Usage

1. Subscribe simple:

   val channel: Channel = WebSocketChannel("wss://echo.websocket.org")
   channel.onMessage = { println(it) }
   channel.send("hello world!")
   Thread.sleep(2000)
   channel.close()

2. Subscribe with channel id:

   val channel: Channel = WebSocketChannel("wss://echo.websocket.org")
   channel.onMessage = { println(it) }
   
   val input = SubscribeInput(
     mapSubscribe = { operation, channelId ->
       when (operation) {
         SubscribeInput.Operation.SUBSCRIBE -> "{\"op\":\"subscribe\",\"channel\":\"$channelId\"}"
         SubscribeInput.Operation.UNSUBSCRIBE -> "{\"op\":\"unsubscribe\",\"channel\":\"$channelId\"}"
       }
     }
   )
   input.add("hello_message")
   
   channel.addChannelListener(input)
