Extend vue.js component from third-party library

Question

I'm using component ElDatepicker from element-ui and I want to change it's template and event handler method. I'm trying to do something like this in single file component:

import Vue from 'vue';
import ElDatePicker from 'element-datepicker'
Vue.use(ElDatePicker)
var dpkr = Vue.component('ElDatePicker')
console.log(dpkr)
export default {
    extends: ['ElDatePicker']
}

But it doesn't work. How i can change it?

Answer 1

Your main problem is that extends should specify a single component and not an array. You should reference the component and not the name.

import Vue from 'vue';
import ElDatePicker from 'element-datepicker'

export default {
  extends: ElDatePicker
}

The repo you posted is from element-ui

Do npm install element-ui

Then:

import { DatePicker } from 'element-ui'
export default {
  // Use mixins for array syntax
  mixins: [DatePicker]
  // OR use extends without array
  extends: DatePicker
}
