The Ultimate Guide to the Input and Output Decorator in Angular
Understanding the power of the Angular input and output decorator can be a great way to take your project development to the next level. This guide from CMARIX will show you all that you need to know about using the input and output decorators so that you can maximize their potential in your projects.
You will learn how to use these two powerful Angular tools together and understand how they work.
In Angular, the @Input() decorator is used to defining a component property that can receive data from its parent component. The basic idea is that a parent component can pass data to its child components by binding to their input properties using property binding.
Here’s a step-by-step explanation of how @Input()works in Angular:
import { Component, Input } from ‘@angular/core’;
@Component({
selector: ‘app-child’,
templateUrl: ‘./child.component.html’,
styleUrls: [‘./child.component.css’]
})
export class ChildComponent {
@Input() title: string;
}
