I would be glad to get some help importing a build-in pipe to a custom one in angular 2.
This is my code :
@Pipe({ name: 'tablePipe' })
export class TablePipe implements PipeTransform {
constructor(private decimalPipe: DecimalPipe) {
}
transform(field: any, format: Format, formatArg: string): any {
let formattedField: any = ''
switch (format) {
case 'number':
{
formattedField = this.decimalPipe.transform(field, formatArg);
break;
}
}
return formattedField;
}
}
export type Format = 'date' | 'string' | 'number';
and this is the error i got:
EXCEPTION: Uncaught (in promise): Error: No provider for DecimalPipe!
When importing regular custom pipes in components, i am using :
@Component({
...,
pipes: [MyCustomPipe],
...
})
For this to work you need to add DecimalPipe to providers somewhere
For example
@NgModule({
providers: [DecimalPipe],
...
})
export class AppModule {}
You can also add it to providers of a component (either the one where you 're using the pipe, or an ancestor component.
