Hello!

 

I have a problem: 

I was going to use kendo-grid with typescript. I use npm packages @progress/kendo-grid-vue-wrapper and typescript version ^2.9.2. When I used sample with localdatasource, I got the error:

 

vue.runtime.esm.js?2b0e:1819 TypeError: Cannot read property 'length' of undefined
    at VueComponent.mounted (index.js?363d:39)
    at callHook (vue.runtime.esm.js?2b0e:3025)
 
in this code @progress/kendo-base-components-vue-wrapper/dist/es/kendo-base-component/index.js?363d
 
 mounted: function mounted() {
        if (this.$el.classList.length > 0) { <-- $this.el is #comment node and does not have classList property
            this.nativeClasses = [].concat(_toConsumableArray(this.$el.classList));
        } else {
            this.nativeClasses = [];
        }

Hi Evgeni,

Yes indeed the Kendo Vue Wrappers are not written in typescript themselves so such error is expected.  In such case I would recommend to exclude the node_modules from the files that are type checked because the code that is generated in them and used there may not be passing some of your type checks.

If the scenario is somehow different please let me know.
