safe-window

A utility for safely getting properties from the window object in projects that render on both the server and the client.

Installation

npm i -S safe-window

Usage

import safeWindow from 'safe-window';

window.foo = {bar: 'baz'}
safeWindow('foo.bar')
=> 'baz'

Works with arrays

window.foo = [{bar: 'baz'}]
safeWindow('foo.0.bar')
=> 'baz'

Window doesn't exist (server side)

safeWindow('foo.bar')
=> null

// With default
safeWindow('foo.bar', 'qux')
=> 'qux'
