What is react-device-detect?
The react-device-detect package is a tool for detecting device types and browser environments in a React application. It provides a set of hooks and components that allow developers to render content conditionally based on the user's device type, operating system, browser, and other device-specific characteristics.
What are react-device-detect's main functionalities?
Device Type Detection
Detects the type of device (mobile, tablet, desktop) and allows you to render content conditionally based on the device type.
import { isMobile, isTablet, isDesktop } from 'react-device-detect';
function MyComponent() {
return (
<div>
{isMobile && <p>This is a mobile device.</p>}
{isTablet && <p>This is a tablet device.</p>}
{isDesktop && <p>This is a desktop device.</p>}
</div>
);
}
Browser Detection
Determines the browser being used (e.g., Chrome, Firefox) and enables conditional rendering of components or content for specific browsers.
import { isChrome, isFirefox } from 'react-device-detect';
function MyComponent() {
return (
<div>
{isChrome && <p>This is viewed in Chrome.</p>}
{isFirefox && <p>This is viewed in Firefox.</p>}
</div>
);
}
Operating System Detection
Identifies the operating system of the user's device (e.g., Android, iOS) and allows for OS-specific content or functionality.
import { isAndroid, isIOS } from 'react-device-detect';
function MyComponent() {
return (
<div>
{isAndroid && <p>This is an Android device.</p>}
{isIOS && <p>This is an iOS device.</p>}
</div>
);
}
Custom Hooks
Provides custom hooks that return an object with device detection booleans, allowing for more dynamic and custom implementations.
import { useDeviceDetect } from 'react-device-detect';
function MyComponent() {
const { isMobile, isDesktop } = useDeviceDetect();
return (
<div>
{isMobile && <p>Content for mobile</p>}
{isDesktop && <p>Content for desktop</p>}
</div>
);
}
Other packages similar to react-device-detect
mobile-detect
A package similar to react-device-detect that offers detailed mobile device detection, including phone/tablet detection, and can parse user-agent strings. It does not provide React-specific hooks or components.
ua-parser-js
This package is used for user-agent string parsing to identify browser, engine, OS, CPU, and device type/model. It is more general-purpose and not React-specific, unlike react-device-detect which provides React components and hooks.
react-responsive
A package that allows for the creation of responsive design in React applications using media queries. It is similar to react-device-detect in providing conditional rendering based on device characteristics but focuses more on responsive design rather than device detection.
react-device-detect
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;
