Is there a v-cloak inverse?

There plenty of solutions, I think another one will be to use v-if with a false property in data like:

<div v-if="false">Loading Vue....</div>
<div v-cloak>vue loaded</div>

As simple as:

<div v-if="false">Will be visible until vue is mounted/ready...</div>

Work for all versions.

The element has to be inside your container... if you use to hide your master container, change it that way:

<div id="app">
    <div v-if="false">Visible while loading...</div>
    <div v-cloak>Visible when ready...</div>
</div>
