Browser Detection in ReactJS

Question

Is there any way to detect IE browser with React and either redirect to a page or give any helpful message. I found something in JavaScript, but not sure how would I use it with React+TypeScript.

var isEdge = !isIE && !!window.StyleMedia;

Answer 1

Try:

const isEdge = window.navigator.userAgent.indexOf('Edge') != -1
const isIE = window.navigator.userAgent.indexOf('Trident') != -1 && !isEdge

etc.

Each browser has a distinct user agent you can check.

These can be faked by the client of course, but in my opinion, are a more reliable long term solution.

You can write test for IE like this.

<script>
     // Internet Explorer 6-11
          const isIE = document.documentMode;
          if (isIE){
            window.alert(
              "Your MESSAGE here."
            )
          }
</script>

This is the service I always use when doing JS/Browser based browser-detection: http://is.js.org/

if (is.ie() || is.edge()) {
  window.location.href = 'http://example.com';
}

You are on the right track you can use these to conditionally render jsx or help with routing...

I have used the following with great success.

Originally from - How to detect Safari, Chrome, IE, Firefox and Opera browser?

// Opera 8.0+
const isOpera = (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;

// Firefox 1.0+
const isFirefox = typeof InstallTrigger !== 'undefined';

// Safari 3.0+ "[object HTMLElementConstructor]" 
const isSafari = /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || (typeof safari !== 'undefined' && safari.pushNotification));

// Internet Explorer 6-11
const isIE = /*@cc_on!@*/false || !!document.documentMode;

// Edge 20+
const isEdge = !isIE && !!window.StyleMedia;

// Chrome 1 - 71
const isChrome = !!window.chrome && (!!window.chrome.webstore || !!window.chrome.runtime);

// Blink engine detection
const isBlink = (isChrome || isOpera) && !!window.CSS;

Please be aware they each stand a chance to deprecated due to browser changes.

I use them in React like this:

 content(props){
    if(!isChrome){
     return (
      <Otherjsxelements/>
     )
    }
    else { 
     return (
      <Chromejsxelements/>
     )
    }
  }

Then by calling {this.Content()} in my main component to render the different browser specific elements.

Pseudo code might look something like this... (untested):

import React from 'react';

const isChrome = !!window.chrome && (!!window.chrome.webstore || !!window.chrome.runtime);

export default class Test extends React.Component {

  content(){
    if(isChrome){
        return (
            <div>Chrome</div>
        )
    } else {
        return (
            <div>Not Chrome</div>
        )
    }
  }

    render() {
        return (
            <div>Content to be seen on all browsers</div>
            {this.content()}
        )
    }
}

This is all information you can get from your the browser of you client (using react):

    let latitude
    let longitude
    const location = window.navigator && window.navigator.geolocation

    if (location) {
      location.getCurrentPosition(position => {
        latitude = position.coords.latitude
        longitude = position.coords.longitude
      })
    }

    var info = {
      timeOpened: new Date(),
      timezone: new Date().getTimezoneOffset() / 60,
      pageon: window.location.pathname,
      referrer: document.referrer,
      previousSites: window.history.length,
      browserName: window.navigator.appName,
      browserEngine: window.navigator.product,
      browserVersion1a: window.navigator.appVersion,
      browserVersion1b: navigator.userAgent,
      browserLanguage: navigator.language,
      browserOnline: navigator.onLine,
      browserPlatform: navigator.platform,
      javaEnabled: navigator.javaEnabled(),
      dataCookiesEnabled: navigator.cookieEnabled,
      dataCookies1: document.cookie,
      dataCookies2: decodeURIComponent(document.cookie.split(';')),
      dataStorage: localStorage,
      sizeScreenW: window.screen.width,
      sizeScreenH: window.screen.height,
      sizeDocW: window.document.width,
      sizeDocH: window.document.height,
      sizeInW: window.innerWidth,
      sizeInH: window.innerHeight,
      sizeAvailW: window.screen.availWidth,
      sizeAvailH: window.screen.availHeight,
      scrColorDepth: window.screen.colorDepth,
      scrPixelDepth: window.screen.pixelDepth,
      latitude,
      longitude
    }
    console.log(info)

The browser is browserName

This almost broke me, but I found something which seems pretty simple and straight forward, use the vendor name. ie. Google, Apple etc. navigator.vendor.includes('Apple') I hope this helps someone out there.
