Within an @NgModule it's common to include in the imports a call to a ModuleWithProviders function, for example RouterModule.forRoot(). The old ngc compiler was able to handle this pattern because it had global knowledge of metadata of not only the input compilation unit but also all dependencies. The ngtsc compiler for Ivy doesn't have this knowledge, so the pattern of ModuleWithProviders functions is more difficult. ngtsc must be able to determine which module is imported via the function in order to expand the selector scope and properly tree-shake directives and pipes. This commit implements a solution to this problem, by adding a type parameter to ModuleWithProviders through which the actual module type can be passed between compilation units. The provider side isn't a problem because the imports are always copied directly to the ngInjectorDef. PR Close #24862 |
