react-browser-support

This component displays a message, if the current browser is not supported. This is determined using a list of supportedBrowsers ( a javascript object). Supported Browsers are specified as an Object to the list prop of <BrowserSupport supported={minBrowserVersions}>.

Installation

npm install react-browser-support --save-dev

Basic

You can use the default <BrowserSupport /> component.

import React from 'react'
import BrowserSupport, { detectBrowser } from 'react-browser-support'

const minBrowserVersions = {
    chrome: '4.10',
    edge: '6',
    firefox: '19.5',
    ie: '10',
    opera: '10.0',
    safari: '10.2',
}
export default class MyComponent extends React.Component {
    componentDidMount() {
        this.setState({ browser: detectBrowser() })
    }
    render() {
        return (
            //...
            <BrowserSupport supported={minBrowserVersions}/>
            //...
        )
    }
}

Custom

You can apply your own style, className & children as props to the component, and it will use those in place of the defaults.

You can also extract the name & version of the current browser, using the function onCheck.

componentDidMount() {
    this.onCheck = this.onCheck.bind(this);
    this.setState({ browser: detectBrowser() })
}
onCheck(browser) {
    this.setState({browser})
}
render() {
    return this.state ? (
        <div>
        {/* With Custom Content */}
        <BrowserSupport
            onCheck={this.onCheck}
            supported={minBrowserVersions}
            className='custom-warning-style'
        />

        {/* With Custom Content & Browser Version, etc. */}
        <BrowserSupport
            onCheck={this.onCheck}
            supported={minBrowserVersions}
            style={inlineWarningStyle}>
            <b>
                {this.state.browser.name} (version: {this.state.browser.version}) unsupported
            </b> 
            <div>
                oh my goodness, we don't seem to support your browser 😳
            </div>
            <div style={{display: 'flex', flexDirection: 'column', marginTop: '1em'}}>
                <a href='https://www.google.com/chrome/browser/desktop/index.html'>Download Chrome</a>
                <a href='https://www.mozilla.org/en-US/firefox/new/'>Download Firefox</a>

            </div>
        </BrowserSupport>
    </div>
    ) : null
}
