bFingerPrint

bFingerPrint is a middleware for Express, that has minimal functionality of its own:

• Save browser fingerprint of a logged user
• A hash is generated with information gathered from a user's browser
• User-Agent, Length of User-Agent, Client's IP, Client's Accept Encoding

If a user with an anonymous browser has already been logged in to the web application, you will know.

Usage:

npm install bFingerPrint

const bFingerPrint = require('bfingerprint')

router.get('/generateFingerPrint', bFingerPrint, (req, res, next) => {
  res.redirect('/dashboard')
})

Fingerprint is added to the req.user.fingerprint
