Custom Pipe working fine on app.component.html but not on other pages

1. Firstly, create pipes folder in src/app folder (in app folder).

2. Second, on cmd "ionic generate pipe pipes/searchfilter" => this will generate two files in pipes.

3. Third, create file in pipes folder with name "pipes.module.ts" and write below code to => "pipes.module.ts"

`import { NgModule } from '@angular/core'; import { CommonModule } from '@angular/common'; import { SearchfilterPipe } from './searchfilter.pipe'; //our pipe which we generate

@NgModule({ imports: [ CommonModule ], declarations: [SearchfilterPipe], exports: [SearchfilterPipe] }) export class PipesModule { } Now we have PipesModule we can generate more pipes and write them in pipesmodule. We will import only PipesModule instead of all pipes.`

4. You do not have to import PipesModule in app.module.ts

5. Now go to page which you want to use pipe and open for example "anasayfa.module.ts" and import "PipesModule" and write it in @ngModel imports(it will be created automatically) Please be careful you will import PipesModule to something.MODULE.TS not something.page.ts

Pass data between pages using Router service

There is multiple ways to pass a parameters from a page to another in Ionic v4 / Angular 7.2+:

• Using Extras State (new since Angular 7.2) - Recommended

Simple and clean

` // original page let navigationExtras: NavigationExtras = { state: { foo: this.foo } }; this.router.navigate(['destination-path'], navigationExtras);

// destination page constructor(private route: ActivatedRoute, private router: Router) { this.route.queryParams.subscribe(params => { if (this.router.getCurrentNavigation().extras.state) { this.foo= this.router.getCurrentNavigation().extras.state.foo; } }); } `
