Access the active screen in Javascript
Accessing the value in plain Javascript is explained here.
React
A example hook that returns the active screen as a string:
useTailwindScreen.js
import { useState, useEffect } from 'react'
export default () => {
const isClient = typeof window === 'object'
function getScreen() {
return window
.getComputedStyle(document.querySelector('body'), ':before')
.getPropertyValue('content')
.replace(/"|'/g, '')
}
const initialState = isClient ? getScreen() : ''
const [screen, setScreen] = useState(initialState)
useEffect(() => {
if (!isClient) {
return false
}
function handleResize() {
setScreen(getScreen())
}
window.addEventListener('resize', handleResize)
return () => window.removeEventListener('resize', handleResize)
}, [])
return screen
}
Component
import React from 'react'
import useTailwindBreakpoint from './useTailwindBreakpoint'
const ActiveScreen => {
const screen = useTailwindBreakpoint()
return (
<span>{screen}</span>
)
}
export default ActiveScreen
