Community-Graph Information Radar

A simple display of community activity from the community graph implemented in Kotlin

We deployed both to Heroku.

The frontend: http://kotlin-kudos.herokuapp.com

The backend: http://kotlin-kudos-backend.herokuapp.com

The dashboard: http://kotlin-dashboard.herokuapp.com

Getting set up

Data from Neo4j is enriched in real-time using Twitter APIs, which require access credentials.

  • Obtain Twitter API creds from apps.twitter.com
  • Register a new application, once done, edit backend/src/main/resources/application.properties

Running the backend

Running the frontend

You'll need node.js, version 7 or above. A nice way to install that is with Node Version Manager.

Statistics Dashboard

The beginnings of a statistics dashboard as a React application can be found in dashboard.

Currently it only lists tweets per month from the backend (StatsRepository).

It is running on: http://kotlin-dashboard.herokuapp.com
