Utilizing child component HTTP responses within a parent component in Angular: a comprehensive guide

As a newcomer to Angular, I find myself struggling with http requests in my application. The issue arises when I have component A responsible for retrieving a list of IDs that need to be accessed by multiple other components.

In component B, I attempted to utilize the list of IDs from component A to retrieve the initial value (the first ID). However, my attempt to use @ChildView in B component did not yield the desired outcome. It seems like Angular is sending the HTTP request but not waiting for the response.

My current workaround involves sending the request from both components, which feels inefficient and somewhat frustrating on my end.

Answer №1

When connecting componentA and componentB, there are different ways to pass data:

  • If ComponentA contains componentB: utilize @Input() properties for passing the data.
  • For the reverse scenario, consider using an EventEmitter or a shared service to store the data securely.

To understand how to implement these methods effectively and see examples of their usage, I recommend checking out the official guide on component interaction.
