Issue with connectionStatus about botframework-directlinejs

[billba]

The only problem with the sample code is that switch(connectionStatus) { .. } should be surrounded by curly brackets. I've fixed this in the README, thanks for the bug report.

To answer your question, ConnectionStatus is a TypeScript enum, which really just means that it's a plan old JavaScript object with values for each field. ConnectionStatus.Uninitialized === 0 and so on. If you want a more descriptive log, try console.log(ConnectionStatus[connectionStatus]) which will show the string value, e.g. "Uninitialized".

I'm closing this issue, but feel free to add more comments if you continue to see problems.

Thanks for the quick response @billba 👍

Sorry but I'm still slightly confused because if I console.log(ConnectionStatus[connectionStatus]) I get 'ConnectionStatus' is not defined. Is that because I'm not using TypeScript or am I missing something here?

In the example in the docs I can't see where ConnectionStatus is supposed to be defined, is this an RX thing or something that I'm missing?

directLine.connectionStatus$
.subscribe(connectionStatus =>
    switch(connectionStatus) {
        case ConnectionStatus.Uninitialized:    // the status when the DirectLine object is first created/constructed
        case ConnectionStatus.Connecting:       // currently trying to connect to the conversation
        case ConnectionStatus.Online:           // successfully connected to the converstaion. Connection is healthy so far as we know.
        case ConnectionStatus.ExpiredToken:     // last operation errored out with an expired token. Your app should supply a new one.
        case ConnectionStatus.FailedToConnect:  // the initial attempt to connect to the conversation failed. No recovery possible.
        case ConnectionStatus.Ended:            // the bot ended the conversation
    }
);

It's not an RxJS or TypeScript thing, just an object exported from the library. You need to import it. If you're using ES6 modules then you'll need to do something like:

import { DirectLine, ConnectionStatus } from 'botframework-directlinejs';

This is not necessarily obvious so I have updated the code samples with import statements.

Ahh that makes way more sense ha. Thanks @billba :)
