We can see that the output directory is set to dist/out-tsc. and there is a special section angularCompilerOptions used for angular.

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "strict": true,
    ...
  },
  "angularCompilerOptions": {
    "enableI18nLegacyMessageIdFormat": false,
    "strictInjectionParameters": true,
