Communication is important, especially neighborhood communication 😎 Let’s collect communication approaches between components.

I remember a time when I jumped to Angular and while developing I had to find the best way to communicate between components.

So, let’s collect them.

We are going to talk about neighborhood communication 😎

Custom Event is a good approach to dispatch events and listen. You should listen event from target Element, Document, and Window, but the target may be any object that supports events (such as XMLHttpRequest). It does not work in IE but for that we have a Polyfill solution.

So, Custom Event Service is going to look like that:

Publish/Subscribe pattern saves a TOPIC name and reference to a callback. When you publish the TOPIC it calls the callback.
