Usage

Composition API or Plugin or Mixin.

	Composition API	Plugin	Mixin
has window sizes properties	only in use	all components	only in use
handle resize event	only in use	all times	all times

Composition API

Use with component.

<template>
  <div>
    <p>window width: {{ windowWidth }}</p>
    <p>window height: {{ windowHeight }}</p>
  </div>
</template>

<script>
import { useWindowSize } from 'vue-window-size';

export default {
  setup() {
    const { width, height } = useWindowSize();
    return {
      windowWidth: width,
      windowHeight: height,
    };
  },
};
</script>

note: useWindowSize handles a Resize Event only when it is in use. Even if it is called by multiple components, the Resize event is processed only once. If it is not used, it will not be handled.

Plugin

Install plugin

import { createApp } from 'vue';
import App from "./App.vue";  // your App component
import { VueWindowSizePlugin } from 'vue-window-size/option-api';

const app = createApp(App);
app.use(VueWindowSizePlugin);

Use with component

<template>
  <div>
    <p>window width: {{ $windowWidth }}</p>
    <p>window height: {{ $windowHeight }}</p>
  </div>
</template>

Mixin

Use with component

<template>
  <div>
    <p>window width: {{ $windowWidth }}</p>
    <p>window height: {{ $windowHeight }}</p>
  </div>
</template>

<script>
import { vueWindowSizeMixin } from 'vue-window-size/option-api';

export default {
  mixins: [vueWindowSizeMixin()],
};
</script>

Config for Option API

delay (option)

• type: Number
• default: 33
  • About 30 FPS

Change delay time of resize event.

e.g.

import { createApp } from 'vue';
import App from "./App.vue";  // your App component
import { VueWindowSizePlugin } from 'vue-window-size/option-api';

const app = createApp(App);
app.use(VueWindowSizePlugin, {
  delay: 100,
});

Public API for Option API

config(config: VueWindowSizeOptionApiConfig)

Same as config for Option API.

import { vueWindowSizeAPI } from 'vue-window-size/option-api';

vueWindowSizeAPI.config({
  delay: 100,
});

init()

Initialize the plugin. Usually called automatically. Please call it if you want to use it again after destroy.

import { vueWindowSizeAPI } from 'vue-window-size/option-api';

vueWindowSizeAPI.init();

destroy()

Remove the resize event.

import { vueWindowSizeAPI } from 'vue-window-size/option-api';

vueWindowSizeAPI.destroy();

FAQ

Why is there no Config in the Composition API?

useWindowSize is a singleton and handles the resize event. Therefore, using useWindowSize(config) will affect all components in used. Due to the nature of the Composition API, this is not the desired behavior. I also think that there are not many use cases that need to be set individually.
If requested, I will create a useAtomicWindowSize(config) that can be set atomically, so please create an issue. Or create a factory function for createUseWindowSize(config).

When is the removeEventListener called when using plugin and mixin??

vue-window-size adds addEventListener only once, even if it is used in mixin. So basically you do not need to call removeEventListener. If you want to call removeEventListener please call destroy method.
