Share information by including the provider within the @component declaration in Angular

I am looking to explore a new method of passing data using providers directly within the component itself. For instance, I am curious if there is a way to pass a variable from one component to another without relying on routing or other traditional methods.

Is it possible for the variable to be dynamic rather than static when passed between components? I prefer not to have the variable be static.

one.component.ts

public dynamicVariable:string = 'pass this data to two component'

two.component.ts

@component({
 selector : 'app-two-component',
 templateUrl: './two.component.html',
 styleUrls: ['./two.component.css'],
 provider: [Onecomponent] // inject OneComponent here
})

export class TwoComponent implements OnInit {

 consructor() {}

 ngOnInit() {
  
 }
}

Answer №1

It is recommended to utilize services within the providers. For more information, refer to the official documentation:

https://angular.io/guide/providers

In your scenario, a sample service could resemble the following code snippet. The scope of these variables can be determined based on where you provide your services.

oneComponent.service.ts

import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root',
})
export class oneComponentService {

  toto:string ;

}

two.component.ts

@component({
 selector : 'app-two-component',
 templateUrl: './two.component.html',
 styleUrls: ['./two.component.css'],
 provider: [oneComponentService] // inject OneComponent here
})

export class TwoComponent implements OnInit {

 consructor(private oneComponent: oneComponentService) {}

 ngOnInit() {
 // access your variables here
  console.log("oneComponent", this.oneComponent.toto);
 }
}
