Cypress builder should transform tsconfig paths

[diginikkari]

Expected Behavior

I expect that modules which are imported using path aliases in tsconfig.json would be transformed to relative paths or e.g. webpack modules.

Current Behavior

If I import module using path alias e.g.

import { ProductType} from '@project/models'

This import is not transformed by tsc and it's still found in compiled js and I get "Error: Cannot find module '@project/models'" -error.

Failure Information (for bugs)

This is know limitation with tsc. Perhaps cypress builder could use webpack which handles tsconfig paths correctly.

My team currently has a need for this as well. Maybe something like https://www.npmjs.com/package/tsconfig-paths could accomplish the same thing without the additional overhead of a bundler like webpack?

@diginikkari could you provide a repro?

[diginikkari]

@vsavkin of course, here is repro repository: https://github.com/diginikkari/repro-for-issue1238

I tried to make it as clean as I could. It's just basic nx workspace with one app and one lib. tsconfig.e2e.json is modified to include lib module and changed outDir, because of that.

app.spec.ts is now failing, because imported module is not found. Hope this helps.
