I'm updating my app to use a module structure and I ran into a weird issue when trying to add my pipe component into a shared module. From what I've read I have everything set up right, so I must be missing something little.
Error: Unhandled Promise rejection: Template parse errors: The pipe 'cmgTitleize' could not be found
I have a BrowseModule
, this module declares a ProjectCardComponent
which has a template that uses the cmgTitleize
pipe. To provide access to the TitleizePipe
I import my SharedModule
.
@NgModule({
declarations: [
...,
ProjectCardComponent
],
imports: [
...,
SharedModule
],
providers: [
...
]
})
export class BrowseModule { }
The SharedModule
, imports the PipesModule
:
@NgModule({
declarations: [
...
],
exports: [
...
],
imports: [
...,
PipesModule
]
})
export class SharedModule { }
PipesModule
declares and exports the TitelizePipe
:
@NgModule({
declarations: [
...
TitleizePipe
],
exports: [
...
TitleizePipe
]
})
export class PipesModule { }
Lastly for a sanity check heres the TitleizePipe:
@Pipe({
name: 'cmgTitleize'
})
export class TitleizePipe implements PipeTransform {
...
}
看起来我只需要在PipesModule
中导出SharedModule
If you're using the static "forRoot()" in a shared module, you still need to export the pipes or any other required module:
@NgModule({
exports: [
MyPipesModule //<---------------- HERE
]
})
export class SharedModule {
static forRoot(): ModuleWithProviders {
return {
ngModule: SharedModule,
providers: [
MySingletonServices
]
};
}
}
And then you just import it in your main app module:
@NgModule({
declarations: [
AppComponent
],
imports: [
SharedModule.forRoot() // <------------
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
