Example

Web

<script src="node_modules/browser-detect/dist/browser-detect.umd.js"></script>

const result = browserDetect();
console.log(result);

output

{
    name: 'chrome',
    version: '58.0.3029',
    versionNumber: 58.03029,
    mobile: false,
    os: 'Windows NT 10.0'
}

Web with module

import browser from 'browser-detect';

const result = browser();
console.log(result);

output

{
    name: 'chrome',
    version: '58.0.3029',
    versionNumber: 58.03029,
    mobile: false,
    os: 'Windows NT 10.0'
}

NodeJS

Just simple

const browser = require('browser-detect');
const result = browser();

console.log(result);

output

{
    name: 'node',
    version: '9.9.0',
    versionNumber: 9.9,
    mobile: false,
    os: 'win32'
}

NodeJS with Express

const router = express.Router();
const browser = require('browser-detect');

router.get('/', req => {
    const result = browser(req.headers['user-agent']);
    console.log(result);
});

return router;

output

{
    name: 'ie',
    version: '9.0',
    versionNumber: 9,
    mobile: false,
    os: 'Windows NT 10.0'
}

Or set a middleware and send to res.locals.

// browserDetectMiddleware.js
const browser = require('browser-detect');

const MiddleWare = () => req => {
    res.locals.browser = browser(req.headers['user-agent']);
    next();
};

module.exports = MiddleWare;

// app.js

const express = require('express');
const browserDetectMiddleware = require('./browserDetectMiddleware');

const app = express();
app.use(browserDetectMiddleware())

View will can access browser variable.

<!-- view.ejs -->

<%=JSON.stringify(browser)%>

output

"{ name: 'firefox', version: '53.0.0', versionNumber: 53, mobile: false, os: 'Windows NT 10.0' }"
