vue3-resize

Detect DOM element resizing

Demo - JSFiddle

Sponsors

Installation

npm install --save vue3-resize

Module import

⚠️ You need to include the package CSS:

 import 'vue3-resize/dist/vue3-resize.css'

Then import the package and install it into Vue:

 // main.js
import { createApp } from 'vue'
import App from './App.vue'
import Vue3Resize from 'vue3-resize'

createApp(App)
  .use(Vue3Resize)
  .mount('#app')

Or:

 import { createApp } from 'vue'
import App from './App.vue'
import { ResizeObserver } from 'vue3-resize'

const app = createApp(App)

app.component('resize-observer', ResizeObserver)
// or
app.component(ResizeObserver.name, ResizeObserver)


app.mount('#app')

Browser

 <link rel="stylesheet" href="vue3-resize/dist/vue3-resize.css"/>

<script src="vue.js"></script>
<script src="vue3-resize/dist/vue3-resize.min.js"></script>

The plugin should be auto-installed. If not, you can install it manually:

 app.use(Vue3Resize)

Or:

 Vue.component('resize-observer', Vue3Resize.ResizeObserver)

Usage

Add the <resize-observer> inside a DOM element and make its position to something other than 'static' (for example 'relative'), so that the observer can fill it.

Listen to the notify event that is fired when the above DOM element is resized.

Example

 <template>
  <div class="demo">
    <h1>Hello world!</h1>
    <resize-observer @notify="handleResize" :showTrigger="true" />
  </div>
</template>

<script>
export default {
  setup() {
    return {
      handleResize ({ width, height }) {
        console.log('resized', width, height)
      }
    }
  }
}
</script>
