(: Import the WebSocket module :)
* First of all: include the websocket module* The function has a <code>$%ws:connect("/")</code> annotation . It gets called if a client successfully creates a websocket WebSocket connection to the path "<code>/</" code> (checkout check out [[WebSockets]] for further information).* Get A JSON response is generated, which contains the <code>new client-id</code> and the a <code>client-path</code> with <code>ws:id()</code> and <code>ws:path()Connect</code>string.* Create a json-result * Broadcast the result This response will be sent to all other connected clients without the calling client.

It gets called if a client sends a new message arrives at the server (checkout [[WebSockets]] for further information).* With <code>ws:ids()</code> you will get the ids of all connected clients.* The function <code>ws:send($messageA JSON response is generated,$first-client-id)</code> sends which contains the <code>$message</code> to the client with the id <code>$first-client-id</code>string.* <code>ws:path($first-client-id)</code> returns the path of the client with the id <code>$first-client-id</code>* To emit a message This response will be sent to all connected clients you call <code>ws:emit($responseincluding the calling client)</code>.
