  var app = new Vue({
    el: '#app',
    data: {
      posts: {}
    },
    mounted: function() { 

    },
    methods: {
      updatePosts: function () {
        $.get('/api/v1/posts',function(response){
          this.posts = response.data;
          setInterval(this.updatePosts, 10000);
        }.bind(this));
      };      
    },
    created: function () {
