Webpack/Babel can't handle '@' in constructor

[ihl396]

Describe the bug

Attempting to generate a react build via webpack and babel-loader fails when there's a parameter decorator in the constructor - even though I included the 'babel-plugin-transform-typescript-metadata' plugin. The workaround is obviously to not include the inject parameter decorator in the constructor and DI manually (which works so I'm unblocked), but this seems like a bug that should be tracked nonetheless?

I've originally referred to this closed issue: https://github.com/microsoft/tsyringe/issues/142 which still did not resolve my issue.

Generated output:

Creating an optimized production build...
Failed to compile.

You may need an additional loader to handle the result of these loaders.

To Reproduce

Generate a build by invoking react-scripts build with the configured webpack.config.js and .babelrc

import "reflect-metadata";
import { container, inject, singleton } from 'tsyringe'

@singleton()
export class App {
  storeService: typeof store
  constructor(@inject("Store") storeService: typeof store) {}
}
