This is a very basic Node app that creates an HTTP server to host a static HTML document that is loaded by headless Chrome (via Puppeteer) in an incognito window and returns all cookies that were set in the browser.
GDPR. Since most third-party servives do not seem to provide a solid list of cookies that they may set on your website when their Javascript is loaded, I had to manually try to find what cookies they set. Instead, I created this basic app that I can add any JS I want to a basic HTML page, run this script, and get an output of all the cookie names.
Sure. It's not very great, I put it together very quickly so I could give a list of cookies to our legal department to be added to our cookie policy, so it could probably be better. Maybe I'll update it to be more useful. ¯\_(ツ)_/¯
