Warnings after upgrade to Angular 10 / TS 3.9.5

Current Behavior

After upgrading to Angular 10 and TypeScript 3.9.5, I get the following warnings when creating a production build of my app:

sebastien@developassion:~/wks/didowi$ npx nx run web:build --prod

... (tons more like that)

In the tsconfig.json files, I have the following:

{
  "extends": "../../tsconfig.json",
  "compilerOptions": {
    "types": ["node", "jest"]
  },
  "include": ["**/*.ts"]
}

I’m not sure if I’ve caused this or if it is the default configuration of NX for apps/libs.

Expected Behavior

No Webpack / TS warnings for *.ngtypecheck.ts files during production builds

Hey all. We suggest to wait with the upgrade until we release Nx v10. We’re already working on it but need some time to make sure to implement the necessary migrations and test it properly.

Once that’s released, you can just upgrade Nx which will then make sure to move your Nx workspace + Angular over to v10 😃

I keep this issue open s.t. we can test it against our v10 release.

🙏 patience is needed, we’re polishing the last rough edges 😉
