## API reference

|
|
|
## Debugging
|
|
|
|
In order to make it easier to debug this extension, we provide a `game.project` setting `websocket.debug`.
|
|
|
|
Set it to:
|
|
|
|
* `0` to disable debugging (i.e. no debug output).
|
|
* `1` to display state changes.
|
|
* `2` to display the messages sent and received.
|
|
|
|
## External resources
|
|
|
|
To verify that your websocket server works, you can test it with some tools.
|
|
|
|
* [websocat](https://github.com/vi/websocat)
|
|
|
|
Or, you can test your server on this web page:
|
|
|
|
* https://www.websocket.org/echo.html
|
|
|
|
To monitor all the packets sent to/from the client/server, you can use e.g.
|
|
|
|
* [Wireshark](https://www.wireshark.org)
|
|
|
|
For command line debugging, there's
|
|
|
|
* tcpdump: `sudo tcpdump -X -s0 -ilo0 port 8080 ` (example for local ws:// connection)
|
|
|
|
* tcpdump: `sudo tcpdump -X -s0 host echo.websocket.org` (Monitors packets to/from echo.websocket.org)
