Can't use with unstable_enablePackageExports metro option (expo)

Cross-posting supabase/realtime-js#415 because I'm not sure you're monitoring the issues on the other repo :)

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

When using @supabase/supabase-js in an expo react native project, if I use the unstable_enablePackageExports with the metro bundler, bundling fails with the following error:

To Reproduce

1. Generate a new expo app
2. Add @supabase/supabase-js as a dependency
3. Create a supabase client in the main _layout.tsx file
4. Run npx expo customize metro.config.js
5. Add config.resolver.unstable_enablePackageExports = true; to metro.config.js
6. Add ios.bundleIdentifier to app.json
7. Run npx expo run:ios

Repro repo: https://github.com/aldebout/supabase-expo-exports-issue

Expected behavior

No crash

Screenshots

System information

• OS: macOS
• Version of supabase-js: 2.45.1
• Version of Node.js: 20.16.0

Additional information

Opening here because the error message I got in my actual project was

The package at "../../node_modules/@supabase/realtime-js/node_modules/ws/lib/stream.js" attempted to import the Node standard library module "stream".
It failed because the native React runtime does not include the Node standard library.

Is there any update on this? I've run into the same issue

I've also run into this when trying to use Storybook and Expo.

I'm able to run it by manually specifying nodeModulesPaths and setting disableHierarchicalLookup to true (in a monorepo setup).
