Creates a script tag, with support for automatically unloading (deleting) the script tag on unmount.

If a script tag already exists for the given URL, useScriptTag() will not create another script tag, but keep in mind that depending on how you use it, useScriptTag() might have already loaded then unloaded that particular JS file from a previous call of useScriptTag().

Usage ​

ts
import { useScriptTag } from '@vueuse/core'

useScriptTag(
  'https://player.twitch.tv/js/embed/v1.js',
  // on script tag loaded.
  (el: HTMLScriptElement) => {
    // do something
  },
)
js
import { useScriptTag } from '@vueuse/core'
useScriptTag(
  'https://player.twitch.tv/js/embed/v1.js',
  // on script tag loaded.
  (el) => {
    // do something
  },
)

The script will be automatically loaded when the component is mounted and removed when the component is unmounted.

Configuration ​

Set manual: true to have manual control over the timing to load the script.

ts
import { useScriptTag } from '@vueuse/core'

const { scriptTag, load, unload } = useScriptTag(
  'https://player.twitch.tv/js/embed/v1.js',
  () => {
    // do something
  },
  { manual: true },
)

// manual controls
await load()
await unload()
