Angular 15: How to Handle State Restoration in a Component After Route Navigation?
I've looked through the documentation and I'm still confused about I tried several approaches but none seem to work. I'm upgrading from an older version and I'm working with an scenario in my Angular 15 application where I need to restore the state of a component after navigating back to it from another route... I'm using a service to manage shared state, but the component is not reflecting the updated state when I return to it. Here’s a simplified version of my service: ```typescript import { Injectable } from '@angular/core'; import { BehaviorSubject } from 'rxjs'; @Injectable({ providedIn: 'root' }) export class StateService { private stateSubject = new BehaviorSubject<any>(null); public state$ = this.stateSubject.asObservable(); setState(newState: any) { this.stateSubject.next(newState); } } ``` In my component, I subscribe to the state like this: ```typescript import { Component, OnInit } from '@angular/core'; import { StateService } from './state.service'; @Component({ selector: 'app-my-component', templateUrl: './my-component.component.html' }) export class MyComponent implements OnInit { state: any; constructor(private stateService: StateService) {} ngOnInit() { this.stateService.state$.subscribe(state => { this.state = state; }); } } ``` The question arises when I navigate away from `MyComponent` to another route and then back. The `ngOnInit` method gets called again, but the `state` variable is not updated with the latest state from the service. I do see the correct state being emitted from the service (verified by logging), but it seems like the subscription isn't updating the component as expected. I’ve tried adding `ChangeDetectorRef.detectChanges()` after setting the state, but that didn't help. Additionally, I have checked to ensure that the component is not being destroyed and recreated properly. Any suggestions on how to ensure that the component reflects the latest state when navigating back? I'm looking for best practices in managing component states across route navigations in Angular 15. Any ideas how to fix this? Any advice would be much appreciated.
