Library that imports JSON file breaks the application build

Type of Issue

[x] Bug Report
[ ] Feature Request

Description

Consuming the library containing a JSON import fails on application build with the following error (library itself is built successfully with both Ivy and ViewEngine):

ERROR in dist/library/public-api.d.ts:1:36 - error TS2307: Cannot find module './example.json' or its corresponding type declarations.

1 export { default as numbers } from './example.json';

Adding "skipLibCheck": true, to tsconfig.base.json silences this error. Ivy built library works fine after that, ViewEngine built library fails with following error:

ERROR in The target entry-point "library" has missing dependencies:
 - ./example.json

How To Reproduce

Checkout the repository: https://github.com/klemenoslaj/ng-package-json-import Execute: yarn && build:lib-ivy - This works fine! Execute: yarn && build:lib-ve - This breaks!

---

Remove skipLibCheck from tsconfig.base.json to fail for both Ivy and ViewEngine.

Expected Behaviour

Application should successfully compile when consuming a library with imported JSON.

I took a quick glance and I saw that you are missing an "resolveJsonModule": true in compilerOptions for tsconfig.base.json

Also, you should never use skipLibCheck.

Are you sure? I am on a phone but i can see the resolveJsonModule in tsconfig.base.json: https://www.github.com/klemenoslaj/ng-package-json-import/tree/master/tsconfig.base.json
