  templateUrl: 'home.html'
})

@Pipe({
	name: 'piper',
     pure: false
})
@Injectable()

Am i missing something pls help.

Do you use lazy loading?

Have you imported the pipes.modules.ts in the page.module.ts?

Here is a exampel for the page.module.ts

import { NgModule } from "@angular/core";
import { IonicPageModule } from "ionic-angular";
import { ProfilePage } from "./profile";
import { PipesModule } from "../../pipes/pipes.module";

@NgModule({
  declarations: [ProfilePage],
  imports: [
    PipesModule,
    IonicPageModule.forChild(ProfilePage)
  ]
})
export class ProfilePageModule {}

Don’t search by pipe. It’s terrible for your performance. Use a pipe for simple formatting only, like for currencies, dates, times.
