Dumb Increment Demo
Websocket connection not initialized | dumb increment-protocol
The incrementing number is coming from the server at 20Hz and is individual for each connection to the server... try opening a second browser window. The button sends a message over the websocket link to ask the server to zero just this connection's number.
Mirror Demo
Websocket connection not initialized | lws-mirror-protocol
Use the mouse to draw on the canvas below -- all other browser windows open on this page see your drawing in realtime and you can see any of theirs as well. The lws-mirror protocol doesn't interpret what is being sent to it, it just re-sends it to every other websocket it has a connection with using that protocol, including the guy who sent the packet. libwebsockets-test-client joins in by spamming circles on to this shared canvas when run.

Close Testing
Websocket connection not initialized | Open and close testing
To help with open and close testing, you can open and close a connection by hand using the buttons. "Close" closes the connection from the browser with code 3000 and reason 'Bye!". "Request Server Close" sends a message asking the server to initiate the close, which it does with code 1001 and reason "Seeya".

This information is sent by the server over a ws[s] link and updated live whenever the information changes server-side.
