Installation

1. Use npm to install the package

$ npm install @ngx-armory/pipes --save

2. You could add to your standalone component or module a specific pipe such as IsNullPipe.

import {IsNullPipe} from '@ngx-armory/pipes';

@NgModule({
 // ...
 imports: [
   // ...
   IsNullPipe
 ]
})

import { IsNullPipe } from '@ngx-armory/pipes';

@Component({
  // ..
  standalone: true,
  imports: [IsNullPipe],
})
export class AppComponent {}

3. Pipes are also injectable and can be used in Components / Services / etc..

import { IsNullPipe } from '@ngx-armory/pipes';

@Component({
  // ..
  providers: [IsNullPipe],
})
export class AppComponent {
  constructor(private isNullPipe: IsNullPipe) {
    const nullable = null;
    this.isNullPipe.transform(nullable); // Returns: true
  }
  // ..
}

4. You can also use pipes as part of your template for ex.

<p>{{ "foo" | isNull }}</p>
<!-- Output: false -->
