Angular 2 NodeJs project - Getstream.io Working Model

I need a WORKING MODEL of the sample project that has been made by Getstream which implements all their features, but I want a working model which sends sample messages from the server side using Node JS, the sample page should coded in Angular 2 which would implement their following features: 1) Follow Feature: Create two users and show how the Follow Feature is implemented. 2) News Feeds: The Flat Feeds (build a feed of text updates) published should show content from the people followed (For example, say USER 2 follows USER 1, and when USER 1 publishes a text update it should be displayed on USER 2's timeline) 3) Feed Aggregation: Show an another sample page which demonstrates how the feeds are aggregated from the people that are followed.( For example, when USER 2 receives more than a few messages from USER 1, they get aggregated) 4) Notification: The notification feed should implement their notification functionality. It is similar to the aggregated feed, but also shows counts of the number of unseen notifications. Notifications should be shown in realtime for unseen activity (Similar like Facebook).
