vue.js proper way to determine empty object
<p>Classic scenario: I want to display a list, but when it's empty I want to display "No data".</p>

<p>The fact that it is somewhat complicated to do something I would expect to be simple makes me think I'm probably doing it wrong.</p>

<p>Here is my current solution.</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"&gt;&lt;/script&gt;
&lt;script src="http://cdn.jsdelivr.net/vue/1.0.16/vue.js"&gt;&lt;/script&gt;

&lt;div id="element"&gt;
  &lt;div v-if="empty"&gt;No item in inventory&lt;/div&gt;
  &lt;div v-for="(index, item) in inventory"&gt;
    {{item.key}}&lt;button onclick="remove('{{index}}')"&gt;remove&lt;/button&gt;
  &lt;/div&gt;
&lt;/div&gt;

&lt;script type="text/javascript"&gt;
"use strict";
var vm;
$(function() {
    vm = new Vue({
        el: '#element',
        data: {
            inventory: {"id1" : {"key" : "val1"}, "id2" : {"key" : "val2"}},
            empty: false
        },
        watch: {
            inventory: function() {
                vm.empty = $.isEmptyObject(vm.inventory);
            }
        }
    });
});

function remove(key) {
  Vue.delete(vm.inventory, key);
}
&lt;/script&gt;</code></pre>
</div>
</div>
</p>

<p>Is there a better solution than this?</p>
