VueResize: A Vue Directive for Detecting DOM Element Size Changes

VueResize is a Vue directive designed to monitor changes in the size of DOM elements, allowing developers to trigger actions when element dimensions change.

Using VueResize is straightforward. You simply need to apply the v-resize directive to the desired element.

HTML:

<div id="app">
  <div v-resize="handleResize">
    This method will be triggered when the element's size changes.
  </div>
</div>

JavaScript:

<script>
import Vue from 'vue';
import VueResize from 'vueresize';

export default {
  name: 'App',

    VueResize,
  },
  methods: {
    handleResize() {
      console.log('Element size has changed');
    },
  },
};
</script>

This code snippet will trigger the handleResize() method when the element's size changes.
