memgraph / reddit-network-explorer

A graph-powered Reddit explorer that can perform real-time graph visualizations and sentiment analysis.

🔍 Reddit Network Explorer 🔍

The Reddit Network Explorer is a web application that lets you visualize a subreddit in real-time as well as perform sentiment analysis and different network analysis algorithms.

📚 Data model

👉 Try it out!

• The demo application - reddit.memgraph.com (Not deployed yet!)
• The Memgraph instance - bolt://reddit.memgraph.com:7687

To explore the data, please download Memgraph Lab. The endpoint is reddit.memgraph.com and the port is '7687'.

🖥️ Run the app locally

The simplest way of running the app locally is by using Docker Compose. Just run the following commands in the root directory:

docker-compose build
docker-compose up backend-app
docker-compose up frontend-app
docker-compose up reddit-stream

Make sure to set up a Reddit account and go to https://www.reddit.com/prefs/apps in order to create an app so you can get the client_id and client_secret. You will need those to set up the Reddit stream in reddit-stream/app.py (line 106-109):

    reddit = praw.Reddit(
        client_id="***REMOVED***",
        client_secret="***REMOVED***",
        user_agent="graph-demo data fetcher")

The app will need to run a while to populate with comments and users, so make sure to keep it running for 10-15 minutes to see some data flowing in.
