Get entrypoint name in webpack loader

Question

I have a bunch of webpack entrypoints configured as described here:

module.exports = {
  entry: {
    pageOne: './src/pageOne.js’,
    pageTwo: './src/pageTwo.js’,
    pageThree: './src/pageThree.js’
  }
}

The entries themselves import various modules. E.g. pageOne.js imports module1.js

I am also using the skeleton loader to act on the raw javascript content (of pageOne.js, pageTwo.js, …)

This loaders callback function´s “this” refers to the “loader context”

My Question: So now I have the files content (e.g. of module1.js) and its corresponding loader context (via this) in the callback. But I need to know the (original/parent) entry name of module1.js. So for module1.js it should tell me that it is part of the original pageOne entry name. Is that possible?
