angular 8 components interaction

How to share data between angular components?
Data sharing between the angular components is possible with the following ways, Firstly, parent to child component communication in angular provides a decorator called @Input decorator which can be used to pass data from Parent to Child. This is one of the most common methods of sharing data from Parent to Child in Angular application.
What are angular components interaction methods?
With the evolution of Angular versions, the interaction methods among Angular components have experienced remarkable changes, enabling seamless communication and collaboration between different parts of the application. Thus, in this quick study, we will explore the different Angular components interaction methods. What Are Components In Angular?
Does angular support inter-component communication?
Nonetheless, if you have multiple components in your angular application and necessitates inter- component communication, then Angular provides you some features and angular components interaction methods.
What is angular UI?
A typical Angular application consists of a lot of components. Each component handles a small part of the UI. These components must interact or communicate together to produce the complete user interface of the application There are few ways in which components can communicate or share data between them.

Component Communication

There are few ways in which components can communicate or share data between them. And methods depend on whether the components have a Parent-child relationship between them are not. Here are the three Possible scenarios 1. Parent to Child Communication 2. Child to Parent Communication 3. Interaction when there is no parent-child relation tektutorialshub.com

Parent to Child Communication

If the Components have a parent-child relationship then, then the parent component can pass the data to the child using the @inputProperty. tektutorialshub.com

Child to Parent Communication

The Child to Parent communication can happen in three ways. 1. Listens to Events from Child 2. Uses Local Variableto access the child in the Template 3. Uses a @ViewChildto get a reference to the child component tektutorialshub.com

Communication When There Is No Relation

If the Components do not share the Parent-child relationship, then the only way they can share data is by using the services and observable. The advantageous of using service is that 1. You can share data between multiple components. 2. Using observable, you can notify each component, when the data changes. Create a Service and create an Angular Ob
