svelte/reactivity/window

This module exports reactive versions of various window values, each of which has a reactive current property that you can reference in reactive contexts (templates, deriveds and effects) without using <svelte:window> bindings or manually creating your own event listeners.

<script> import { innerWidth, innerHeight } from 'svelte/reactivity/window'; </script>  <p>{innerWidth.current}x{innerHeight.current}</p>

import { const devicePixelRatio: {  readonly current: number | undefined; }devicePixelRatio.current is a reactive view of window.devicePixelRatio. On the server it is undefined. Note that behaviour differs between browsers — on Chrome it will respond to the current zoom level, on Firefox and Safari it won’t.
