Change favicon to

用法

¥Usage

import { useFavicon } from '@vueuse/core'

const icon = useFavicon()

icon.value = 'dark.png' // change current icon

传递源引用

¥Passing a source ref

你可以将 ref 传递给它，源引用的更改将自动反映到你的图标上。

¥You can pass a ref to it, changes from of the source ref will be reflected to your favicon automatically.

import { useFavicon, usePreferredDark } from '@vueuse/core'
import { computed } from 'vue'

const isDark = usePreferredDark()
const favicon = computed(() => isDark.value ? 'dark.png' : 'light.png')

useFavicon(favicon)

当传递源引用时，返回引用将与源引用相同

¥When a source ref is passed, the return ref will be identical to the source ref

const source = shallowRef('icon.png')
const icon = useFavicon(source)

console.log(icon === source) // true
