Angular Tutorial - 15 - Component Interaction

[@thehoangnguyen9985]

On the latest Angular 6 version, in order to work, you will have to comment out the default import { EventEmitter } from 'events' and include EventEmitter from '@angular/core' I don't really know what is the EventEmitter from events is, they have the same name but different purpose it seems. Can anyone explain this?

[@Codevolution]

The video is reflects Angular 5 but it has changed in Angular 6 as you point out. I will pin this comment so that it will be helpful for others with the same problem. Thanks

[@idlevandal69]

Has the video been updated? He is importing EventEmitter from @angular/core at 5:50

[@johan_maximus]

You saved my life (Y)

[@vatsalshah6505]

should have show multiple value passing. just a suggestion.

[@endrefidje5698]

Will there be an updated version of these Angular tutorials based on Angular 7? Seems to be a few things "broken" now.

[@Skaxarrat]

I just found your tutorials and I'm enjoying them. This is my 15th video in a row :) Can you do sometimes videos doing small projects (20-60 min vídeos) where you create a small SPA? This way we could learn how to put every thing we learnt together.

[@SoumilShah]

I have learned more from your videos than Udemy course Good luck Great Job !!!

[@nellyville8657]

[@IAmNumber49]

Thank you very much... I feel like a loser while programming in angular, but now I've watched this, it helped me a lot to understand how that works.

[@lifeislove9750]

Your way for teaching is really really awesome. 👌👌👌

[@VolodymyrM_UA]

If you get "Can't bind to 'parentData' since it isn't a known property of 'app-test'" error message, check if your test component's selector is defined as Tag: 'app-test' (and used as custom HTML tag: in the app component). Because Class selector: '.app-test' () and Attribute selector: '[app-test]' ( ) will not work, with the above error.

[@betterahyosi]

Yes I also stuck here

[@mdfarooq97]

One of the best, to-the-point Angular tutorials. Great Job! Keep it up! I would like to know something more about the component interaction, I have a case where components are not in parent-child relationship and I would like to communicate between them using events, is this possible? For example, There is AppComponent which holds two other components inside it, ComponentA and ComponentB, will it be possible for ComponentA to send events to ComponentB?

[@naveenm283]

yup I am stuck in the same situation

[@kishanlal676]

Why don't you pass the data from ComponentA to Parent and Parent to ComponentB? I don't know whether there is any straightforward solution for this.

[@imrohan97]
