SocketRocket (Ably Fork)

Carthage Compatible

A conforming WebSocket (here.
You can compare to what modern browsers look like here.

SocketRocket currently conforms to all core ~300 of CocoaPods

Add the following line to your Podfile:

pod 'SocketRocketAblyFork'

Run pod install, and you are all set.

  • Carthage

    Add the following line to your Cartfile:

    github "ably-forks/SocketRocket"

    Run carthage update, and you should now have the latest version of SocketRocketAblyFork in your Carthage folder.

  • Using SocketRocket as a sub-project

    You can also include SocketRocket as a subproject inside of your application if you’d prefer, although we do not recommend this, as it will increase your indexing time significantly. To do so, just drag and drop the SocketRocket.xcodeproj file into your workspace.

  • API


    The Web Socket.


    SRWebSocket will retain itself between -(void)open and when it closes, errors, or fails.
    This is similar to how NSURLConnection behaves (unlike NSURLConnection, SRWebSocket won’t retain the delegate).


    @interface SRWebSocket : NSObject
    // Make it with this
    - (instancetype)initWithURLRequest:(NSURLRequest *)request;
    // Set this before opening
    @property (nonatomic, weak) id <SRWebSocketDelegate> delegate;
    // Open with this
    - (void)open;
    // Close it with this
    - (void)close;
    // Send a Data
    - (void)sendData:(nullable NSData *)data error:(NSError **)error;
    // Send a UTF8 String
    - (void)sendString:(NSString *)string error:(NSError **)error;


    You implement this

    @protocol SRWebSocketDelegate <NSObject>
    - (void)webSocketDidOpen:(SRWebSocket *)webSocket;
    - (void)webSocket:(SRWebSocket *)webSocket didReceiveMessageWithString:(NSString *)string;
    - (void)webSocket:(SRWebSocket *)webSocket didReceiveMessageWithData:(NSData *)data;
    - (void)webSocket:(SRWebSocket *)webSocket didFailWithError:(NSError *)error;
    - (void)webSocket:(SRWebSocket *)webSocket didCloseWithCode:(NSInteger)code reason:(nullable NSString *)reason wasClean:(BOOL)wasClean;


    Included are setup scripts for the python testing environment.
    It comes packaged with vitualenv so all the dependencies are installed in userland.

    To run the short test from the command line, run:

      make test

    To run all the tests, run:

      make test_all

    The short tests don’t include the performance tests
    (the test harness is actually the bottleneck, not SocketRocket).

    The first time this is run, it may take a while to install the dependencies. It will be smooth sailing after that.

    You can also run tests inside Xcode, which runs the same thing, but makes it easier to debug.

    • Choose the SocketRocket target
    • Run the test action (⌘+U)

    TestChat Demo Application

    SocketRocket includes a demo app, TestChat.
    It will "chat" with a listening websocket on port 9900.

    TestChat Server

    The sever takes a message and broadcasts it to all other connected clients.

    It requires some dependencies though to run.
    We also want to reuse the virtualenv we made when we ran the tests.
    If you haven’t run the tests yet, go into the SocketRocket root directory and type:

    make test

    This will set up your virtualenv.

    Now, in your terminal:

    source .env/bin/activate
    pip install git+

    In the same terminal session, start the chatroom server:

    python TestChatServer/py/

    There’s also a Go implementation (with the latest weekly) where you can:

    cd TestChatServer/go
    go run chatroom.go


    Now, start (just run the target in the Xcode project).
    If you had it started already you can hit the refresh button to reconnect.
    It should say "Connected!" on top.

    To talk with the app, open up your browser to http://localhost:9000 and start chatting.

    WebSocket Server Implementation Recommendations

    SocketRocket has been used with the following libraries:

    The Tornado one is dirt simple and works like a charm.
    (IPython notebook uses it too).
    It’s much easier to configure handlers and routes than in Autobahn/twisted.


    We’re glad you’re interested in SocketRocket, and we’d love to see where you take it.
