I m trying to import an NgModule into a standalone component but the compiler is throwing the error NG2012 : Component imports must be standalone components, directives, pipes, or must be NgModules. NgModule({ declarations: [FooComponent], exports: [FooComponent], }); export class FooModule {} let comps = [ImageComponent, HighlightDirective]; @Component({ selector: app-root , standalone: true, imports: [FooModule], template: ``, }) export class ExampleStandaloneComponent {}

I lost over 30 minutes, on this. The NgModule is malformed : NgModule should have been @NgModule.

I ran into this error message while prototyping something and just quickly added a @Directive to the same file as my component: // ❌ Component imports must be standalone components, // directives, pipes, or must be NgModules.(-992012) @Directive({ selector: [myDirective] , standalone: true, }) class MyDirective { ... } @Component({ standalone: true, imports: [ MyDirective ], }) export class MyComponent { ... } Exporting the directive class resolved the issue: // ✅ Works without error! @Directive({ selector: [myDirective] , standalone: true, }) export class MyDirective { // <---- added "export" ... } @Component({ standalone: true, imports: [ MyDirective ], }) export class MyComponent { ... }
