Hi Chris,
The interface to the application programmer is less clear. Is the expectation that you'd use the WebSocketData type class?
I want the library to be flexible for both high- and low-level scenarios. Basically, there are three ways to use the library: * For a really low-level server (e.g. you want to send control frames such as pings yourself), you can use the `sendFrame`, `receiveFrame`, `sendMessage` and `receiveMessage` methods. * For a typical application, you would indeed use `sendDataMessage` and `receiveDataMessage`, as you said. * In some cases, the user doesn't care about the internal representation of frames (binary or text), and he just wants to send and receive messages in some format. For this scenario, there is the `WebSocketsData` typeclass, and the `receiveData` method. I hope this clears things up a little (I'll add an explanation like this to the docs), Cheers, Jasper
