Ok I'm sure its not impossible but it feels that way.

I've spent 2 full weeks trying to properly configure a monorepo with pnpm, turbo, nextjs, react native and jest. I can get everything working perfectly but the second react-native (with expo) enters the repo everything falls apart.

I can run the expo app from the monorepo and import packages from the ui folder but testing is a whole other story. react-native needs the node-linker=hoisted flag set which usually makes it hard for jest in the mobile app package to find a needed dependency.

Also if I import a custom react-native component from the ui folder, import it into the mobile app and try to test it I usually get an error Invariant Violation: __fbBatchedBridgeConfig is not set, cannot invoke native modules like this.

I think I've gone through every monorepo resource on the internet that mentions react-native and/or jest and still can't configure it properly.

I did find this helpful boilerplate but it uses yarn workspaces which I believe handles node_modules differently than pnpm.

If anyone has any idea how to do this please point me in the right direction.

Thanks!
