Does your NPM package run at Edge?
summary
Demonstrates that an NPM package can run on Node, Cloudflare Workers, Vercel Edge Runtime and Deno by using conditional exports and subpath imports to provide runtime-specific entry points (one folder per runtime) while avoiding default exports and the dual package hazard; shows Clerk’s auth library compiled once to run in browser, Node and Edge, polyfilling fetch with node_fetch/native (node-fetch has ~5M daily downloads) and using WinterCG API keys to keep behavior consistent.
