API docs lack auth reference

There is a crossbarexamples example of using WAMP-CRA with AutobahnJS, but the JS API docs don't tell you how to do it

In fact, the API reference for AutobahnJS does not seem to contain any information regarding authentication at all.

@csmcanarney welcome to autobahn! I did end up figuring out how to tie into the auth by looking at source code so what's your question?

Thank you, @erichonkanen! It seems like I'm in the same spot as you: I was able to solve all my issues by looking at the source code.

Here is my coffeescript code that handles creating the autobahn connection optionally with challenge auth...

  _getConnection: ->
    ###
    Returns a new or existing Autobahn websocket connection.

    @private
    @method _getConnection
    @return autobahn.Connection
    ###
    token = @get 'session.data.authenticated.token'
    connection = =>
      onchallenge = (session, method, extra) ->
        if method == 'ticket'
          if token
            return token
          else
            throw new Error 'Missing required token.'
        else
          throw new Error 'Invalid method type.'
      _config =
        initial_retry_delay: 0
        max_retries: -1
        max_retry_delay: 0
        realm: "foo-app"
        retry_delay_growth: 0
        retry_delay_jitter: 0
        url: config.chatHost
      # Check if the user is authenticated and if so set the authmethods.
      if @get 'session.isAuthenticated'
        _config['authid'] = @get 'session.data.authenticated.user.username'
        _config['authmethods'] = ['ticket']
        _config['onchallenge'] = onchallenge
      new autobahn.Connection _config
    return @set('connection', @get('connection') or connection())

This reminds me why I stopped using CoffeeScript :)

[erichaus]

@agronholm completely subjective... I'd rather use coffeescript all day everyday than vanilla js

[agronholm]

These days I prefer TypeScript.

@meejah can you share example url?

[alexey2baranov]

@erichonkanen can you please rewrite your code in JS
