  1. Great tutorial!

    Everything works right out of the box except for the following minor details

    – move extends directive to top of file in game/templates/main.html
    – remove extraneous backslashes from game/consumers.py
    self.room_name = self.scope\[‘url_route’\][‘kwargs’][‘room_code’]

    1. none of this works for me…
      [HTTP/1.1 404 Not Found 0ms]

      [HTTP/1.1 404 Not Found 7ms]

      Firefox can’t establish a connection to the server at ws://localhost:8081/ws/play/xxx/. game.js:5:17
      Socket is closed. Reconnect will be attempted in 1 second. game.js:132:17

  2. Great tutorial, in addition to Silkentrance updates, for django 4 I had to make the following changes:

    – game.js – change event.path[0] to event.composedPath()[0]
    – routing.py – change django.conf.urls import url to from django.urls import re_path
    – routing.py – change url to re_path in websocket_urlpatterns

    Thank you for putting this together!
