how to define few ws routes?

hello

how to define few ws routes?

for example,
from page 1 we connect to ws://localhost:8080/echo
and from page 2 we connect to ws://localhost:8081/ws2

but in dlang serverino code -

// Accept a new connection only if the request path is "/echo"
@onWebSocketUpgrade bool onUpgrade(Request req){
  return req.path == "/echo";
}

// Handle the WebSocket connection
@endpoint void echo(Request r, WebSocket ws){
  // Read messages from the client
  while(true){
    // Only if the message is valid
    if( WebSocketMessage msg = ws.receiveMessage() ){
      // Send the message back to the client
      ws.send("I received your message: `" ~ msg.asString ~ "`");
    }
  }
}

@route!"/"
@endpoint void index(Request r, Output o){ o.serveFile("static/index.html"); }

@route!"/style.css"
@endpoint void css(Request r, Output o){ o.serveFile("static/style.css"); }

what - and how - needs to change here?
for get different paths - and handlers - for different ws paths - as for different http path

thank you

WebSockets, by their nature, work differently from handling HTTP requests.

In your code, inside the function @onWebSocketUpgrade bool onUpgrade(Request req), you need to decide whether to accept the incoming request that is attempting to establish a connection between the client and your server.

If you want two WebSockets to respond to two different URLs, you probably want to do something like return req.path == "/echo" || req.path == "/ws2"; — this means that any request attempting to connect to one of those two URLs will be accepted (maybe you want to do some extra checks?).

Keep in mind that from that point on, all WebSocket connections will execute the code inside @endpoint void echo(Request r, WebSocket ws) in separate and isolated processes.

yep

but we can have different handlers/endpoints for different pages

for example, how this is in erlang with n2o framework
https://github.com/221V/n2o_4.4/blob/master/samples/apps/review/src/routes.erl

for every page we have other module, that handles http request in main() and ws messages in event(E) functions
router you can see above by link

(in other words -- every html page like /page1 , /page2 etc has own ws endpoint like /ws/page1, /ws/page2 etc, and erlang module that handles page requests - serves both - http and ws requests-messages etc)

all WebSocket connections will execute the code inside @endpoint void echo(Request r, WebSocket ws) in separate and isolated processes

ok, but how I can create 2 ws endpoints with serverino ?
how to handle /echo and /ws2 -- to work with ws messages from different/separated pages in different functions (in different ways)?

maybe my 1st message was not too detail explain about what I am ask.. have hope now I clear my question..
thank you)

You have to do by yourself: inside a function @endpoint void route(Request r, WebSocket ws) you can make check on r.path for example and call another function if (r.path == "/ws/page2") page2(r, ws); else ...
