Reactive Programing (observables & Rxjs) - Data archi

Data architecture using observables and services

In a reactive application Services play 2 roles:

1. Provide streams of data that our application can subscribe to

2. Provide operations to add or modify data

• The services maintain streams which emit models (e.g. Messages)
• The components subscribe to those streams and render according to the most recent values
