// Uncommment the following to see NativeScript-Vue output logs
Vue.config.silent = false;

console.log(store.state);
store.dispatch("auth/init").then(user => {
  if (user) {
    router.replace("home");
  } else {
    router.replace("login");
  }
});

new Vue({
  router,
  store,

TNSPusherBeams.addDeviceInterest('debug-hello');
  TNSPusherBeams.addDeviceInterest('hello');
  console.log(TNSPusherBeams.getDeviceInterests());
  TNSPusherBeams.clearDeviceInterests();
  setTimeout(() => {
    TNSPusherBeams.addDeviceInterest('debug-hello');
    TNSPusherBeams.addDeviceInterest('hello');
    TNSPusherBeams.addDeviceInterest('osei');
  }, 5000);
  // TNSPusherBeams.addOnMessageReceivedCallback(message => {

// Prints Vue logs when --env.production is *NOT* set while building
