# Full Screen

The Fullscreen API adds methods to present a specific Element (and its descendants) in full-screen mode, and to exit full-screen mode once it is no longer needed. This makes it possible to present desired content—such as an online game—using the user's entire screen, removing all browser user interface elements and other applications from the screen until full-screen mode is shut off.

# State

The useFullscreen function exposes the following reactive state:

import { useFullscreen } from 'vue-use-web';
import { ref } from '@vue/composition-api';

const elem = ref(null);

const { isFullscreen } = useFullscreen(elem);
State Type Description
isFullscreen Boolean If the element is currently in full screen mode.

# Methods

The useFullscreen function exposes the following methods:

import { ref } from '@vue/composition-api';
import { useFullscreen } from 'vue-use-web';

const elem = ref(null);

const { enterFullscreen } = useFullscreen(elem);
Signature Description
enterFullscreen(void) Enters the fullscreen mode for the element.
exitFullscreen(void) Exits the fullscreen mode from all elements.

# Example

    <video ref="el" src="https://vjs.zencdn.net/v/oceans.mp4" controls></video>
    <button @click="enterFullscreen">Go Full!</button>

import { useFullscreen } from 'vue-use-web';
import { ref, onMounted } from '@vue/composition-api';

export default {
  setup() {
    const el = ref(null);
    const { enterFullscreen, exitFullscreen } = useFullscreen(el);

    onMounted(() => {
      setInterval(() => {
      }, 5000);

    return {
