npm

Detect device, and render view according to the detected device type.

Installation

To install, you can use npm or yarn:

npm install react-device-detect --save

or

yarn add react-device-detect

When to use this library

This library uses a technique called user agent sniffing to detect device information. That means it works by examining the User Agent string given by a browser and comparing it to a list of browser and device names it knows about. This technique works, but has drawbacks and may or may not be the right approach, depending on what you're trying to achieve. If you need to detect a specific browser type (e.g. Chrome, Safari, Internet Explorer) or specific category of device (e.g. all iPods), this library can do that. If you just want your React app to behave differently or look different on mobiles in general, CSS @media queries and matchMedia are probably what you want. There are many libraries that can help with using @media queries and matchMedia in React projects, such as react-responsive and @react-hook/media-query.

API

Usage

Example:

import { BrowserView, MobileView, isBrowser, isMobile } from 'react-device-detect';
<BrowserView>
  <h1>This is rendered only in browser</h1>
</BrowserView>
<MobileView>
  <h1>This is rendered only on mobile</h1>
</MobileView>

if you don't need a view, you can use isMobile for conditional rendering

import {isMobile} from 'react-device-detect';

function App() {
  renderContent = () => {
    if (isMobile) {
      return <div> This content is available only on mobile</div>
    }
    return <div> ...content </div>
  }

  render() {
    return this.renderContent();
  }
}

If you want to leave a message to a specific browser (e.g IE), you can use isIE selector

import { isIE } from 'react-device-detect';

function App() {
  render() {
    if (isIE) return <div> IE is not supported. Download Chrome/Opera/Firefox </div>
    return (
      <div>...content</div>
    )
  }
}

If you want to render a view on a specific device and with a specific condition:

import { browserName, CustomView } from 'react-device-detect';

function App() {
  render() {
    return (
      <CustomView condition={browserName === "Chrome"}>
        <div>...content</div>
      </CustomView>
    )
  }
}

Style the view

You can style a view component by passing class to the className prop

<BrowserView className="custom-class">
  <p>View content</p>
</BrowserView>

or you can pass inline styles to style prop

const styles = {
  background: 'red',
  fontSize: '24px',
  lineHeight: '2',
};
<BrowserView style={styles}>
  <p>View content</p>
</BrowserView>

Testing

import * as rdd from 'react-device-detect';

rdd.isMobile = true;

// use in tests
