reconnecting-websocket | small decorator for the JavaScript WebSocket API | Websocket library

It looks like the answer is to implement "ping pong". This prevents the firewall or proxy from terminating the connection.

If you ping a websocket (client or server) then the specification says it has to respond (pong). But Javascript websocket depends on the browser implementation so it is best to implement a 30 second ping on the server to all clients. e.g.

The issue appears to be a conflict between the monaco namespace provided by monaco-editor and the namespace of the same name provided by monaco-editor-core. When both are installed as dependencies, TypeScript seems to assume that monaco.editor.IStandaloneCodeEditor is referring to the latter, which causes issues since the created monaco.editor is imported from the former.

To resolve this, removing monaco-editor-core as a dependency fixes the confusion and uses the correct typings for monaco.editor.IStandaloneCodeEditor.

The basic strategy for dealing with navigation away from the page, page close or errors is this: The client creates the websocket connection on page load. The server expects client connections to come and go and cleans up resources when the client connection errors.

Here's why you get the error 'websocket: close sent': When the user navigates away from the page, the browser sends a close message to the server as part of the websocket closing handshake. The Gorilla package responds to the close message by sending another close message back to the client. From that point on, the server cannot send messages on the connection. The connection returns an error from write methods after the close message is sent.

Close messages are returned as errors from the websocket read methods. To fix the problem, modify the code to handle errors in general. There's no need to handle the closing handshake specifically.

Here's the updated code. The wsEndpoint function creates a channel for the reader to signal the writer that the reader is done. The defer ws.Close() statement is removed because the reader and writer goroutines will take responsibility for closing the connection.

You have a typo: room_name _json instead of room_name_json.

In var roomName = {{ room_name _json }};.

Please, check your build. If you will see that the Django launches the "development server" instead of "ASGI/Channels", it means that the PyInstaller runs the server using the "runserver.py" of "django.core", but you need launch the "runserver.py" of the "channels".

For this you need in the file PyInstaller/hooks/rthooks/pyi_rth_django.py change this string:
'runserver': 'django.core',
with this:
'runserver': 'channels',

One of the approaches could be as below.

Inside WebSocket.js create a function that accepts a navigation property and save it to the class for example

please try this:

in models.py add class Meta:

By looking at your models, in your views you can make a context and then in your messages room you can use that context with django template tag, to loop all the chat rooms of your user, try this:

Edit (after seeing the actual error):

The problem is you're trying to use .toFixed on something that is not a number. To guard against it, you have to wrap the value in Number.
