RxStarscream

A lightweight extension to Starscream to track websocket events using RxSwift observables.

Installation

CocoaPods

RxStarscream is available through CocoaPods.
Add the following line to your Podfile:

pod 'RxStarscream'

Then run:

pod install

RxStarscream version vs Swift version.

Below is a table that shows which version of RxStarscream you should use for
your Swift version.

Swift	RxStarscream	RxSwift
>= 4.2	>= 0.10	>= 4.3
< 4.2	>= 0.8	>= 4.0
3.X	0.7	3.0.0 - 3.6.1

Carthage

Add this to your Cartfile

github "RxSwiftCommunity/RxStarscream"

Then run:

carthage update

Usage examples

After installing via CococPods or Carthage, you should import the framework.

import RxStarscream

Once imported, you can open a connection to your WebSocket server.

socket = WebSocket(url: URL(string: "ws://localhost:8080/")!)
socket.connect()

Now you can subscribe e.g to all of the websocket events:

socket.rx.response.subscribe(onNext: { (response: WebSocketEvent) in
	switch response {
	case .connected:
		print("Connected")
	case .disconnected(let error):
		print("Disconnected with optional error : \(error)")
	case .message(let msg):
		print("Message : \(msg)")
	case .data(_):
		print("Data")
	case .pong:
		print("Pong")
  	}
}).disposed(by: disposeBag)

Or just to a connect event:

socket.rx.connected.subscribe(onNext: { (isConnected: Bool) in
	print("Is connected : \(isConnected)")
}).disposed(by: disposeBag)

Or just to a message event:

socket.rx.text.subscribe(onNext: { (message: String) in
	print("Message : \(message)")
}).disposed(by: disposeBag)

Sample Project

There’s a sample project (you need to run carthage update for it to compile).

The sample project uses echo server - https://www.websocket.org/echo.html

Have fun!
