The Cloudflare worker is responsible for delivering the latest fingerprinting client-side logic and proxying identification requests and responses between your site and Fingerprint Pro's APIs.

Fingerprint Pro Cloudflare worker

Fingerprint is a device intelligence platform offering 99.5% accurate visitor identification.

Fingerprint Pro Cloudflare Integration is responsible for

• Proxying download requests of the latest Fingerprint Pro JS Agent between your site and Fingerprint CDN.
• Proxying identification requests and responses between your site and Fingerprint Pro's APIs.

This improves both accuracy and reliability of visitor identification and bot detection on your site.

Requirements

• Fingerprint Pro account with the Owner role assigned.
• A website served by Cloudflare. For maximum accuracy benefits, your website should be proxied by Cloudflare (not DNS-only).

See the Cloudflare integration guide for more details.

Put the current worker version into `INT_VERSION`

The monitoring handlers is sending the current worker version to cdn.
Need to get current version from package.json and replace INT_VERSION value during the worker's build.

CF-worker: Remove psl code from index.js and add it as a dependency

We use psl library to retrieve domain name from URL.
Currently, psl code is locates directly in the source code of cf-worker (https://github.com/necipallef2/cf_worker).

We need to put the library as an external dependency in package.json for better maintenance of the source code.

Psl links:
https://github.com/lupomontero/psl/
https://www.npmjs.com/package/psl

Update:
Psl library has outdated public suffix list of domain.

Up-to-date version can be found at https://publicsuffix.org/list/

Bug with `getEffectiveTLDPlusOne`

getEffectiveTLDPlusOne parses incorrectly when a TLD+2 domain may resemble but not exactly match the input.

Steps to repro:

getEffectiveTLDPlusOne('jurajuhlar.com')

Expected:

'jurajuhlar.com'

Actual:

''

Reason:
'jurajuhlar.com' gets matched with ar.com TLD.

Add actual version of end-user script to the `develop` branch during the `release` workflow

Return errors in a correct format for the agent
