Cloudflare with node compatibility
I am trying to deploy remix app which is built with vite on cloudflare.
I am getting errors like ERROR: Could not resolve "crypto".
I added compatibility_flags = [ "nodejs_compat" ] flag into the wrangler file.
I do not directly use crypto module, the library I use uses it. Does anyone know how to make it work so that those libraries import with node: prefix?

If you're using Cloudflare Pages you have more limited options. They're working on a compat flag
experimental:nodejs_compat_v2 to make the node: prefix not required but it's still experimental/being worked on.
You could try monkeypatching it if your code runs before the lib does, assigning what you need to globalThis.crypto from the node: prefix
but not everything is supported eitherway: https://developers.cloudflare.com/workers/runtime-apis/nodejs/crypto/
Patching the lib is the last optionCloudflare Docs

The node:crypto module provides cryptographic functionality that includes a set of wrappers for OpenSSL’s hash, HMAC, cipher, decipher, sign, and verify functions.
