A website to watch subreddits go dark in realtime.
Reddark pulls the list of participating subreddits from the threads on r/ModCoord. If you are the moderator of a sub that is going dark and that is not displayed on Reddark, you can message the r/ModCoord moderators to request that the subreddit is added to the relevant thread.
This is using Express to host the frontend and Socket.io to serve data. Quite simple code, and not too hard to get your head around. This is based on the Original work of D4llo with permission.
