It can be helpful when you try to get a list of your local devices over WiFi when the devices includes at least one websocket connection.
This package allows you detect all devices over your local network with websocket connection.
You've to add a timeout and an array of ports as parameters. The package will try to create a connection with those ports and return the ip addresses which have successful connection.
