Send message to all connected web socket clients

[mer23]

I'm using Jooby's MVC routes for an API. I have also set up a websocket, to which a few clients connect. What I'm trying to do is send a message to all connected websocket clients whenever a specific http request is received in the server. This is how my route method looks like:

    @Path("/player")
    @Produces("application/json")
    public class PlayerRoute {
        @POST
        public Result newPlayer(Request req, @Body Player player) {
            //this is what I'm trying to achieve..
            allWebsocketSessions.foreach(session ->
                    session.send("a new player has been created")
            );
            return Results.ok();
        }
}

I've read jooby's documentation but can't figure out how to do it.

Thanks in advance.

Correct, there is no way to do such thing today. But what you showed me should works.

Go to your application do something like:

public static final List<WebSocket> allWebsocketSessions = new CopyOnWriteArrayList<>();

{
    ws("/ws", ws -> {
       sessions.add(ws);

       ws.onClose(() -> sessions.remove(ws));
    }); 
}

From your controller you can access to allWebsocketSessions.

It is a (not that ugly) workaround.

Let's keep this open and will find a way to do it automatically.
