Uncaught (in promise): Error: Type EventcardComponent does not have 'ɵmod' property.

This error occurs in Angular when you have copied a module or component but you did not rename the class properly.

Solution

Make sure the components module file has the right "export class xModule" function inside xModule.ts.

A second solution is that you possibly want to import a component inside another component. Make sure you import the module, rather than the component. So:

imports: [EventcardModule,

Instead of

imports: [EventcardComponent,
