Angular 16 - Issues with State Management Between Parent and Child Components Using NgRx
I'm trying to figure out I tried several approaches but none seem to work. I'm currently facing a challenge with state management in my Angular 16 application that uses NgRx for state management. I have a parent component that holds a state slice and a child component that needs to read and update this state. The problem is that the child component is not reflecting the changes when the state updates, and I'm not sure why. In my parent component, I'm using a selector to get the state: ```typescript import { Component, OnInit } from '@angular/core'; import { Store } from '@ngrx/store'; import { Observable } from 'rxjs'; import { selectMyState } from './store/selectors'; @Component({ selector: 'app-parent', templateUrl: './parent.component.html', }) export class ParentComponent implements OnInit { myState$: Observable<MyState>; constructor(private store: Store) {} ngOnInit() { this.myState$ = this.store.select(selectMyState); } } ``` Here’s how I'm using it in the template: ```html <div *ngIf="myState$ | async as myState"> <app-child [childData]="myState.data"></app-child> </div> ``` In the child component, I'm trying to handle input changes like this: ```typescript import { Component, Input } from '@angular/core'; import { Store } from '@ngrx/store'; import { updateData } from './store/actions'; @Component({ selector: 'app-child', templateUrl: './child.component.html', }) export class ChildComponent { @Input() childData: any; constructor(private store: Store) {} onUpdate() { // Update the state when the button is clicked this.store.dispatch(updateData({ newData: this.childData })); } } ``` The issue arises when I update the state in the child component using the `onUpdate` method. Although the state seems to be updated (verified with NgRx DevTools), the child component does not re-render with the new `childData`. I’ve confirmed that the `@Input()` property is actually being updated, but the view doesn’t reflect this change. I’ve tried using `ChangeDetectorRef` to force a check, but it didn’t help. Here's what I attempted: ```typescript import { ChangeDetectorRef } from '@angular/core'; // Inside the constructor: constructor(private store: Store, private cdr: ChangeDetectorRef) {} // After dispatching the action: this.store.dispatch(updateData({ newData: this.childData })); this.cdr.detectChanges(); ``` This didn’t solve the problem, and it feels like I might be missing something fundamental about how inputs and change detection work in Angular with NgRx. Any insights or suggestions on how to properly synchronize state between these components would be greatly appreciated! This is part of a larger service I'm building. Am I missing something obvious? Could this be a known issue?
