Transferring data from two child components back to the parent component

Within my web application, I have a parent component (A) and two children components (B, C). The parent component is responsible for maintaining the basic layout of the page, which remains consistent across all layouts. However, I need to dynamically swap out the contents in the middle of the page based on user interactions with buttons.

In order to achieve this functionality, I have outlined the following steps:

  1. User clicks button from parent component A, triggering a refresh to display child component B
  2. User interacts with a button within child component B, causing a refresh to switch to child component C

Given the requirement to maintain the base layout from parent component A throughout these transitions, I am seeking suggestions on how best to approach Step 2 without losing this persistence.

Answer №1

To implement this functionality, routing is essential. Within component A, you are required to insert your code and include 

<router-outlet></router-outlet>
in the markup. For defining routing within component A, follow these steps:

const routes = [
   { path: '', component: 'AComponent', children: [
     {path: '', redirectTo: 'b', pathMatch: 'full'},
     {path: 'b', component: 'BComponent'},
     {path: 'c', component: 'CComponent'},
   ]}  
]

Upon clicking a button, navigate to the designated route using [routerLink].
