Fighting TLS fingerprinting with Node.js

The modern internet is full of services that want to know who you are. Fingerprinting is the latest way to do this: capturing many small details about your client, and using it to create an id that’s sufficiently unique to recognize you and infer details about your network client and device. This is a privacy problem, which I’m not going to focus on here, but collecting and analysing interaction metadata is also a powerful tool to recognize certain types of clients, even when they attempt to disguise themselves.
