To initialize the Validator, either:

Initializing with Webpack

  1. Install Kendo UI and add a theme.

    npm install --save @progress/kendo-ui
    npm install --save @progress/kendo-theme-default
  2. Install the Kendo UI Validator package for Vue.

    npm install --save @progress/kendo-validator-vue-wrapper
  3. Import the Kendo UI packages to the App component. If you use the Kendo UI components more than once in your application, add all Kendo UI-related files to the main.js file. If you use the Kendo UI components once in your application, add the Kendo UI-related files the component where they will be referred.

    import '@progress/kendo-ui' // This will import the entire Kendo UI library
    // As an alternative, you could import only the scripts that are used by a specific widget:
    // import '@progress/kendo-ui/js/kendo.validator' // Imports only the Validator script and its dependencies
    import '@progress/kendo-theme-default/dist/all.css'
    import { Validator, ValidatorInstaller } from '@progress/kendo-validator-vue-wrapper'
    new Vue({
    	el: '#vueapp',
    	components: {
