  import * as React from "react"
  
  const MOBILE_BREAKPOINT = 768
  
  export function useIsMobile() {
    const [isMobile, setIsMobile] = React.useState<boolean | undefined>(undefined)
  
    React.useEffect(() => {
      const mql = window.matchMedia(`(max-width: ${MOBILE_BREAKPOINT - 1}px)`)
      const onChange = () => {
        setIsMobile(window.innerWidth < MOBILE_BREAKPOINT)
      }
      mql.addEventListener("change", onChange)
      setIsMobile(window.innerWidth < MOBILE_BREAKPOINT)
      return () => mql.removeEventListener("change", onChange)
    }, [])
  
    return !!isMobile

Read the script before you install anything that runs on your machine. This is the one part of a plugin that acts without being asked.
