Executing a method during the initialization process in app.component.ts

Question

Executing a method during the initialization process in app.component.ts

One thing I've noticed is that the <app-root> component in Angular doesn't implement OnInit like all the other components. It may sound silly, but let's say I wanted to add a simple console.log('Hello World') statement to display every time the app-root component is loaded (just for illustrative purposes), where should I place this code and does it require a specific function name (e.g. ngOnInit())? Or is the main purpose of angular to simply act as a wrapper that initializes other components.

Below is the basic structure as set up by the Angular CLI:

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'app';
}

Answer №1

Absolutely, you have the ability to incorporate it just like any other components:

import { Component, OnInit } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  title = 'app';

  ngOnInit() {
    console.log();
  }

}

Furthermore, it's not a matter of whether you should or shouldn't do it. Similar to everything else, there needs to be a purpose behind it. It truly hinges on what you are aiming to achieve. This is what would more accurately determine the correctness or incorrectness, as well as good or bad practice.*
