This middleware port original PHP script to Connect/Express JS
npm install --save evercookie
Evercookie backend middleware needs cookie, thus
express.cookieParser() middleware must come before Evercookie backend middleware.
In addition, express server must serve front end assets, such as index.html and evercookie.js as well.
var express = require'express';var evercookie = require'evercookie';var app = express;appuseexpresscookieParser;appuseevercookiebackend;appuseexpresscookieParser;appuseexpressstatic__dirname + '/public'; // be careful, you may want to use path.join instead!
Customized settings can be used, but up to this moment, it makes no sense to change the dafault one,
as all these values are hardcoded in (frontend)
//...appuseevercookiebackendpngCookieName: 'evercookie_png'etagCookieName: 'evercookie_etag'cacheCookieName: 'evercookie_cache'pngPath: '/evercookie_png.php'etagPath: '/evercookie_etag.php'cachePath: '/evercookie_cache.php';//...
