Thanks for this great library @claviska!
Tried adding Shoelace to a Rails app w/ the current guide. When starting the Webpack Dev Server, the following error gets thrown:
```
.../RailsApplication/config/webpack/development.js:5
module.exports = environment.toWebpackConfig()
```
Adding `module.exports = environment` as done [here in the example repo](4114da0e14/config/webpack/environment.js (L20)) fixes the issue and allows Webpack to compile.
