I rewrote my auth library to run on Cloudflare Workers. Here is what broke.

Most TypeScript auth libraries assume Node.js. They reach for crypto.randomBytes , Buffer , the Node fs module, sometimes process.env directly. That works on Vercel serverless, AWS Lambda with the Node runtime, Railway, Fly. It does not work on Cloudflare Workers. Workers do not have Node. They have Web APIs. crypto means Web Crypto, not the Node crypto module. Buffer is gone. fs is gone. process.env does not exist. Bindings are injected into a request handler.
