As mentioned by @Fiete the vm variable wont be available by default.

You need to define vm globally to access it from the console.

Something like this should work

var vm = new Vue({
  el: '#app',
  data: {
    a: 1
  },
  router,
  template: '<App/>',
  components: {
    App
  }
});

global.vm = vm; //Define you app variable globally

Now you can use vm.$data.PROPERTY or vm.PROPERTY.

The vm variable does not exists by default. And vuejs does not set that variable. If you want to debug your vuejs application I recommend the vuejs Chrome extension.

By opening the extension on your page you can select the component you want to debug. After that you can access the selected component by using the $vm0 variable.
