NgRx Smartish

NgRx Smartish is a small utility library that makes creating "smartish" components in Angular a breeze. NgRx mixed with Smartish Components, provide a clean and declartive approach to building applications in Angular.

Getting Started

You can install the package using npm install @briebug/ngrx-smartish

Next you will need to import NgRxSmartishModule in app.module as well as provide store using the SMARTISH_STORE_TOKEN.

import { NgRxSmartishModule, SMARTISH_STORE_TOKEN } from '@briebug/ngrx-smartish';
imoprt { StoreModule, Store } from '@ngrx/store';

@NgModule({
  imports: [
      NgRxSmartishModule,
      StoreModule.forRoot({...})
  ],
  providers: [{ provide: SMARTISH_STORE_TOKEN, useClass: Store }]
})
export class AppModule {}

SmartSelect

With SmartishNgRx you can reference NgRx Selectors directly in your Angular Component's template without the need to inject the store. You simple need to add the MemoizedSelector in your component class and reference that property with the smartSelector pipe in your template.

import { selectError } from 'YOUR-STORE'

@Component({
    selector: 'app-error',
    template: `<p>{{ selectError | smartSelect | async }}</p>`
})
export class ErrorComponent {
    error = selectError;
}

SmartDispatch

With SmartishNgRx you can dispatch actions directly in your Angular Component's template without the need to dispatch an @Output() EventEmitter or injecting the store. You simply can use either the smartDispatch method.

import { smartDispatch } from '@briebug/ngrx-smartish';
import { addTaco } from '...my-actions';

@Component({
    selector: 'app-component',
    template: `<button (click)="addTaco({ taco: form.value })">Add Taco</button>
})
export class MyComponent {
    addTaco = smartDispatch(addTaco);
}

NgRxSmartishComponent

With SmartishNgRx you can reference your NgRx store directly in your Components classes (or templates) without providing the store in the constructor. It's as easy as having your component extends SmartishNgRxComponent.

@Component({
    selector: 'app-tacos',
    template: `<app-taco *ngFor="let taco of (tacos$ | async)" [taco]="taco></app-taco>`
})
export class TacosComponent extends SmartishNgRxComponent {
    tacos$ = store.select(selectTacos);
}

Testing

Testing with NgRxSmartish is made simple with the NgRxSmartishTestingModule. Just import NgRxSmartishTestingModule into your TestBed with the forRoot() static method. You can also pass an optional MockStoreConfig inside of forRoot() to save you from having to provide provideMockStore(...) in your tests.

const config = { };
describe('YourSmartishComponent', () => {
  beforeEach(async () => {
    imports: [NgRxSmartishTestingModule.forRoot({ initialState: {...}})],
    declarations: [YourSmartishComponent]
  });
});
