Vue not updating ARRAY properly using unshift
The main issue here is that when you are looping over a component, you are required to use a key.
In 2.2.0+, when using v-for with a component, a key is now required.
That being the case, your template should look like this:
<feed v-for="feed in feedData" :key="feed.id" :feedContent="feed"></feed> where feed.id is a unique value in each feed object. This is because of Vue's DOM update strategy. Using a key helps Vue identify which components need to be created/destroyed.
Are you using the key param in your template? Like this?
:key="<An ID>"For instance:
<div v-for="(item, index) in array" :key="item.id"> {{index}} - {{item.name}}</div>
