☯️ React hook to determine if you are on the server, browser, or react native

Need to know when you're on the server, in the browser or in react native in your components/hooks? This simple hook makes it easy. 🔥

Features

• SSR (server side rendering) support
• TypeScript support
• Zero dependencies
• React Native support

Examples

• Example - Next.js - codesandbox container (sometimes containers are buggy, if so try this example)

Installation

yarn add use-ssr      or     npm i -S use-ssr

Usage

import useSSR from 'use-ssr'

const App = () => {
  var { isBrowser, isServer, isNative } = useSSR()
  
  // Want array destructuring? You can do that too!
  var [isBrowser, isServer, isNative] = useSSR()
  
  /*
   * In your browser's chrome devtools console you should see
   * > IS BROWSER: 👍
   * > IS SERVER: 👎
   *
   * AND, in your terminal where your server is running you should see
   * > IS BROWSER: 👎
   * > IS SERVER: 👍
   */
  console.log('IS BROWSER: ', isBrowser ? '👍' : '👎')
  console.log('IS SERVER: ', isServer ? '👍' : '👎')
  console.log('IS NATIVE: ', isNative ? '👍' : '👎')
  return (
    <>
      Is in browser? {isBrowser ? '👍' : '👎'}
      <br />
      Is on server? {isServer ? '👍' : '👎'}
      <br />
      Is react native? {isNative ? '👍' : '👎'}
    </>
  )
}
