Vue instance for specific Blade Templates - Spark

How can i create Vue instance for specific Blade templates. I am not interested in making components and registering them to app.js because if i write something in app.js

blade.php

var app1 = new Vue({
  el: '#app1',
  data: {
    message: 'Life is good. Seems like it is working'
  }
})

var app2 = new Vue({
  el: '#app-2',
  data: {
    message: 'You loaded this page on ' + new Date().toLocaleString()
  }
})

i just want simple Vue instance for a specific blade template
