Reactive favicon
例子
Change favicon to
Usage
js
import { useFavicon } from '@vueuse/core'
const icon = useFavicon()
icon.value = 'dark.png' // change current icon
import { useFavicon } from '@vueuse/core'
const icon = useFavicon()
icon.value = 'dark.png' // change current icon
传递一个ref(Passing a source ref)
您也可以传递 ref 给它，ref的更改将自动作用到你的图标。
You can pass a ref to it, changes from of the source ref will be reflected to your favicon automatically.
js
import { computed } from 'vue'
import { useFavicon, usePreferredDark } from '@vueuse/core'
const isDark = usePreferredDark()
const favicon = computed(() => isDark.value ? 'dark.png' : 'light.png')
useFavicon(favicon)
import { computed } from 'vue'
import { useFavicon, usePreferredDark } from '@vueuse/core'
const isDark = usePreferredDark()
const favicon = computed(() => isDark.value ? 'dark.png' : 'light.png')
useFavicon(favicon)
传递ref时，返回引用将与ref相同
When a source ref is passed, the return ref will be identical to the source ref
ts
const source = ref('icon.png')
const icon = useFavicon(source)
console.log(icon === source) // true
const source = ref('icon.png')
const icon = useFavicon(source)
console.log(icon === source) // true
