Guide on Implementing a Function Post-Rendering in Angular 2+

I'm looking to implement some changes in the Service file without modifying the Component.ts or directive file. Here's what I need: 1) I want to add an event listener after the service renders its content (which is generated by a third-party tool that includes HTML content that can only be identified through inspection and obtaining an ID). 2) Why is it not recommended to use lifecycle hooks inside a service.ts file?

Answer №1

Q: What is the reason why service files do not have any life cycle hooks?

A: Life cycle hooks were designed for components. They are triggered when a user navigates between components, with the previous component being destroyed and the new one being initialized. This cycle of destruction and initialization mimics the concept of life, hence the need for life cycle hooks in components.

In contrast, service files serve as helper classes for the application's functionality. They are initialized when the application is created and remain active until the user closes the application, as they do not require any life cycle hooks.
