useBreakpoints

Demo

source

Current breakpoints: []

Active breakpoint:

xs(<640px): false

xs(<=640px): false

sm: false

md: false

lg: false

xl: false

2xl: false

greaterThanBreakPoint: false

Usage

import { breakpointsTailwind, useBreakpoints } from '@vueuse/core'

const breakpoints = useBreakpoints(breakpointsTailwind)

const smAndLarger = breakpoints.greaterOrEqual('sm') // sm and larger
const largerThanSm = breakpoints.greater('sm') // only larger than sm
const lgAndSmaller = breakpoints.smallerOrEqual('lg') // lg and smaller
const smallerThanLg = breakpoints.smaller('lg') // only smaller than lg

vue

<script setup lang="ts">
import { useBreakpoints } from '@vueuse/core'

const breakpoints = useBreakpoints({
  mobile: 0, // optional
  tablet: 640,
  laptop: 1024,
  desktop: 1280,
})

// Can be 'mobile' or 'tablet' or 'laptop' or 'desktop'
const activeBreakpoint = breakpoints.active()

// true or false
const laptop = breakpoints.between('laptop', 'desktop')
</script>
