[iOS] error: bundling failed: Error: Unable to resolve module ./build/index

[esutton]

Has anyone succeeded to get this TypeORM example working on either iOS or Android?

I would love to find an ORM to replace Realm JS.

git clone https://github.com/typeorm/react-native-example.git
cd react-native-example
yarn
react-native run-ios

Results in red box error:

I cannot get Android to even get this far.

react-native run-android

Could not install the app on the device, read the error above for details.
Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

Hello @esutton
I am also facing similar error.
I ran:
git clone https://github.com/typeorm/react-native-example.git cd react-native-example yarn react-native run-ios
I got the errors about "Build input file cannot be found:" for double-conversion.cc, cached-powers.cc, diy-fp.cc, strtod.cc, fast-dtoa.cc, bignum.cc, fixed-dtoa.cc, bignum-dtoa.cc.

I noticed that react-native-sqlite-storage is not linked, so I did link it. now I got the error "'config.h' file not found"

So I cleaned the project and switched the build to legacy from the project settings. but the error stayed, I tried using relative path in project settings, but the error stayed the same.

Hello @esutton

I have created a boiler plate for myself from scratch using the docs and two issues' comments:

1. the problem with "experimentalDecorators" was solved using: “transform-decorators-legacy” does not work with next@7 vercel/next.js#5231 (comment)

2. I had a problem with types -not sure why- but I had to specify the type in the entity, I got that thanks to: Column type for UserModel#userId is not defined and cannot be guessed. Make sure you have turned on an "emitDecoratorMetadata": true option in tsconfig.json. typeorm#2897 (comment)

The repo was tested with ios & android, I hope it helps you
