IvanNavarroCode · 2023-02-22T17:38:33Z

Add a more specific error message when defining a lazy-loaded route using loadComponent and passing it an NgModule instead of a standalone component, when the user should actually be using loadChildren.

Other information

I wasn't sure how to check if the value was a NgModule. If there's a better way please let me know.

Add a more specific error message when defining a lazy-loaded route using `loadComponent` and passing it a NgModule instead of a standalone component, when the user should actually be using `loadChildren`.

packages/router/src/utils/config.ts


 export function assertStandalone(fullPath: string, component: Type<unknown>|undefined) {
-  if (component && !isStandalone(component)) {
+  if (component && (component as any)[NG_MOD_DEF]) {


Hmm, I think it would probably be worth exporting isNgModule from the private exports at this point. https://github.com/angular/angular/blob/main/packages/core/src/render3/jit/util.ts#L18

I saw it but indeed it is private. Should I add it to the exports of core in this PR?

NG_MOD_DEF is exported from https://github.com/angular/angular/blob/main/packages/core/src/core_render3_private_export.ts. You can add isNgModule as another private export there.

… NgModule

I see that you just added the action: merge label, but the following checks are still failing:
status "ci/circleci: test_win" is failing

If you want your PR to be merged, it has to pass all the CI checks.

If you can't get the PR to a green state due to flakes or broken main, please try rebasing to main and/or restarting the CI job. If that fails and you believe that the issue is not due to your change, please contact the caretaker and ask for help.
