Creating an extension of a Vue.js component from a third-party library

I'm currently using the ElDatepicker component from element-ui and I am looking to customize its template and event handler method. I have attempted to achieve this within a 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']
}

Unfortunately, my attempts have been unsuccessful. Any advice on how to successfully make these changes?

Answer №1

The primary issue you are facing is that the 'extends' keyword should specify a single component instead of an array. It is important to reference the component directly rather than its name.

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

export default {
  extends: ElDatePicker
}

The repository you shared belongs to element-ui.

To resolve this, run npm install element-ui

Then, modify your code as follows:

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

Answer №2

If you're looking to incorporate Element UI into your project, start by running npm install element-ui in your terminal. Next, make sure to modify your main.ts/main.js file by including the following lines:

import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';

Vue.use(ElementUI);

Following these steps should address any issues you may encounter. Need further assistance? Visit Element UI.
