port issue

[ajayashuba]

how do i make sure the port is not used by any other instance if i choose port by myself there is some % chance that that port might be in use ..is there way to programatically access the free port given by the system

For all the recent and future readers, you can use https://github.com/doppiaQ/cordova-plugin-portfinder

Then start the webserver like that:

portfinder.getPort().then((port) => {
    webserver.start(
          function() {
            console.log("Started the HTTP server on port ", port);
          },
          function() {
            console.log('Failed to start the HTTP server');
          },
          port
    )
}).catch((e) => {
    console.log("Failed to find a free port");
});
