Challenge Overview

Challenge Objectives

  • Node.js

  • JavaScript

Individual requirements

  • The SPA will need to demonstrate below three flows

  1. How would a TC admin "manually" push ad hoc announcements such as announcing a community town hall event.

  2. How do we send something like the above event to targeted audiences? (another feed group)

  3. How do we automatically add something like announcing challenge winners to the newsfeed?

  • You also need to provide an auto-script to allow us to push multiple feed items automatically and the pushed feeds should be displayed on the UI for corresponding members:


For #1 above, any members should receive the feed item.

For #2 above, only certain amount of members should receive the feed item

For #3 above, only the members registered in the corresponding challenge should receive the feed item.

We perferral it written using nodejs.
