Vue.js v-cloak Directive

Last Updated : 07 Jun, 2022

The v-cloak directive is a Vue.js directive that will remain on the element until the associated Vue instance finishes compilation. Combined with CSS rules such as [v-cloak] { display: none }, this directive can be used to hide uncompiled mustache bindings until the Vue instance is ready. First, we will create a div element with id as app, and let's apply the v-cloak directive to an element.

Syntax:

Template:

<element v-cloak>
    // content....
</element>

CSS:

[v-cloak] {
  display: none;
}

Parameters: This function doesn't accept any parameter.

Example: This example uses Vue.js to show the working of the data with v-cloak so that it becomes visible only when the compilation completes.
