module.name_mapper not working

[cphrdev]

Hello. I have a problem with flow checking one of my webpack alias.

So i have something like:
config.resolve.alias['react-myLib'] = myLib/rslds/src
or
config.resolve.alias['react-myLib'] = myLib/rslds/lib
depending on env variable.

So i do imports inside my component files like this:
import { TableComponent } from 'react-myLib';

It is working fine but flow giving me an error:
Cannot resolve module react-myLib.

So i tried do this inside my .flowConfig:
module.name_mapper='^react-myLib\/\(.*\)$' -> 'empty/object'
but that didn't help.
I tried different regex and solutions but nothing worked for me.
Someone have an idea how to fix it ?

With module.name_mapper there are no builtin functions of objects. You're basically telling flow to redirect imports from one place to resolve from another. In your case, you're saying resolve from a library called empty instead of react-myLib. Do you have empty installed?

This is a common stack overflow post that people refer to but usually forget to actually import the empty lib
