Package Exports

browser_fingerprint
browser_fingerprint/dist/browserFingerprint.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (browser_fingerprint) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Browser Fingerprint

Note: This package requires node v8, as it makes uses of native classes.

This module attempts to uniquely identify browsers by examining their header and connection information. This information can be used as a "poor-man's" session identifier in your node projects. This module can optionally set a cookie to 'lock' in a consistent fingerprint.

Resuming sessions require that either the cookie be returned to the server, or a x-header x-__browserFingerprint in the default case, be sent on subsequent requests

const http = require("http");
const port = 8080;

const { BrowserFingerprint } = require("browser_fingerprint");

// these are the default options
const options = {
  cookieKey: "__browser_fingerprint",
  toSetCookie: true,
  onlyStaticElements: true,
  settings: {
    path: "/",
    expires: 3600000,
    httpOnly: null,
  },
};

const fingerPrinter = new BrowserFingerprint(options);

http
  .createServer((req, res) => {
    let { fingerprint, elementsHash, headersHash } = fingerPrinter.fingerprint(
      req
    );
    headersHash["Content-Type"] = "text/plain"; // append any other headers you want
    res.writeHead(200, headersHash);

    let resp = `Your Browser Fingerprint: ${fingerprint} \r\n\r\n`;
    for (let i in elementsHash) {
      resp += `Element ${i}: ${elementsHash[i]}\r\n`;
    }

    res.end(resp);
    console.log(
      "request from " +
        req.connection.remoteAddress +
        ", fingerprint -> " +
        fingerprint
    );
  })
  .listen(port);

console.log(`server running at http://127.0.0.1:${port}`);
