Can't build app if both itself and its dependency have a dependency on tns-core-modules

Describe the bug

I'm making a React renderer for NativeScript (try to stay calm). It depends upon tns-core-modules. However, when I install this React renderer as a dependency of a sample app, when building the sample app (whether with or without the --bundle flag), Xcode finds duplicates of tns-core-modules and thus tns-core-modules-widgets. This could be related to the webpack config (which is using the defaults from tns create sample --tsc)..?

# Where 'sample' is the app that consumes the React renderer library 
cd sample
tns run ios --clean

Frameworks from tns-core-modules (e.g. TNSWidgets.framework) are referenced from both the consumer project and the library.

** BUILD FAILED **

Unable to apply changes on device: A77F52A9-0201-47A7-8523-1F7C0CFBD57C. Error is: Command xcodebuild failed with exit code 65.

To Reproduce

1. Create a library that depends on tns-core-modules
2. Create an app that installs that library, and also depends upon (the same) version of tns-core-modules

Expected behavior

App is supposed to build correctly.

Additional context

npm dedupe gets things working, but does also remove all the duplicate dependencies in your library folder, preventing you from developing your library.

@shirakaba in the plugin source remove the tns-core-modules from the dependency list. You could install the tns-core-modules as a devDepedency (e.g. as done here) and that won't prevent you from accessing the tns-core-modules in your plugin code (e.g. as done here) as each NativeScript project would have the tns-core-modules installed in the end (e.g. your demo called sample is installing tns-core-modules as dependency).

[shirakaba]

Fantastic, that works!

I've applied your suggested fix in commit 92682e3 of my repo.

[NickIliev]

@shirakaba glad to hear you are able to move forward! As a side note I've read your roadmap and noticed that you need TSX support so perhaps you could refer to this plugin for inspiration.

[shirakaba]

@NickIliev That's invaluable, thank you! I'll add that as a note in the repo.

Before I can get as far as TSX, I'll first need to figure out how to bootstrap the app. I'll file this issue that I'm blocked on under the NativeScript main repository in a moment; would be glad of any help with that, as well!

EDIT: it's more of a question than a bug, so I've submitted it to StackOverflow instead.
