Declare and use local variables per connection

[lzaiko]

Hi Alex,

I’m having an issue to declare a local variable foo (see below) which is only visible inside the socket connection handlers (open, message, close).

cost port = 9000;
const app = uWS.App()
          .ws('/', {
              maxPayloadLength: 1024 * 1024,
              idleTimeout: 15,
              open: (ws, req) => {
                  foo = true;
              },
              message: (ws, message, isBinary) => {
                 if(foo) {
                   // do something with the message
                  }
              }
          }).listen(port, token => {
             console.log(`WebSocket server listening on: ${port}`);
          });
});

The variable foo can’t be declared globally, otherwise it will be visible for all the connections (total mess).

I checked the examples but couldn’t find a solution to my problem.
Help appreciated.

You've got an extra set of }) at the end that needs to be removed, and open event does not have req so you need to remove that, and if you want to share something across open and message events you should put it in the ws object

open:ws=>{
   ws.foo=true
},
message:(ws,message,isBinary)=>{
   console.log(ws.foo)
}
