Angular2 - Call A Function From Another Standalone Component. Basically, Call Function From Outside Component

I'm loading in a component (Component1) another standalone component(Component2) that contains a form. Imagine you have made a form component and I want to integrate it in my compo

Solution 1:

Without much context, I think you need a service to do this. If there's no relation between those 2 components, why would you call a function from component 2? Put save logic into a service and inject it on whatever component you need it.

Solution 2:

This is about the component interaction, you need to use service for communicating between two different components. Main thing is the dependency injection of Angular.

Simply you can use Subject.
