This is example of simple Vue plugin. It works exatcly same as the Vue instance data property, but the name is gunData.<br>
The cool part is that every property in the gunData is realtime synced via gunDB to every other page viewer!<br>
<table>
<tr>
<td>
Vue instance data:
<pre>{{ $data }}</pre>
</td>
<td valign="top" style="text-align:right;">
test<br>
arr[1]<br>
obj.a<br>
deepObj.level1.prop<br>
deepObj.level1.arr[1]<br>
</td>
<td valign="top">
<input v-model="test"><br>
<input v-model="arr[1]"><br>
<input v-model="obj.a"><br>
<input v-model="deepObj.level1.prop"><br>
<input v-model="deepObj.level1.arr[1]"><br>
<input v-if="obj.newProp_1" v-model="obj.newProp_1"><br>

<button @click="addProp()">Add new prop to obj</button>
