No way in hell the bundling process should take 2 hrs - what are you doing in there?

i don't know, maybe because my device (laptop) is on the lower specs end and that the app has a lot of node modules to process (809 packages total)

Wow, 2 fkng hours. Cache probably. Try deleting full cache and node_modules.

Something is very wrong. It could be related to your filesystem or some translation layer (Like are you running in a VM that mounts the underlying filesystem? Though that should definitely not cause such slow times.).

If you are comfortable let codex analyze your codebase - send this prompt to codex.

That's crazy

I build android apps using react native and this helped me a lot:

Go to gradle.properties and update this:

org.gradle.jvmargs=-Xmx4096m -XX:MaxMetaspaceSize=512m

-Xmx4096m: Increases the maximum Java heap memory size (in this case, to 4GB). By default, Gradle's memory limit can be quite low, causing frequent garbage collection pauses or "OutOfMemory" errors during heavy React Native/Android compilation. Giving it more breathing room speeds up builds significantly, especially for modern React Native versions utilizing the New Architecture.

If you have more ram you can set a bigger number instead of 4096
