I've read several posts that claim to fix this issue with importing 'core-js/es7/reflect'. But when I look at the output of the 'ng serve' command, I've noticed the polyfills.ts file is not compiled.
A small sidenode. I'm using the single-spa lib so I need to use this builder as documented by the lib. I want my production to build the single-spa application and use 'ng serve' in dev mode to develop my application locally.
To Reproduce Create an empty project with the configuration above.
Expected behavior A working application.

This sounds similar to an issue I was having:
Can't resolve all parameters for Component: (?).
I resolved it by adding the following to tsconfig.spec.json:
"emitDecoratorMetadata": true,
This commit in my jest-demo-app project shows the exact change.
@arnevdv
I started following your steps:
- created empty app
- pasted your package.json and angular.json
Then I noticed I cannot run it locally, because your angular.json replaces main.ts with another file that should contain single-spa-angular related logic.
I'm not sure if somebody is able to reproduce your error because you have to paste ALL files here (including main.single-spa.ts and extra-webpack.config.js).
It would be the best fit if you create a minimal reproduction repo on github.
Secondly, Angular bundles core-js/es7/reflect under the hood itself if your app is running in the development mode and it should not be bundled if your app is running in prod.
@arturovt Thanks for your help! @arnevdv I'm afraid without a reproduction repo we're unable to help you indeed.
