what i’ve got
what i wanted
Realtime feedback, reports, visualizations while playing Tetris. It should be separate from the data entry application.
These visualizations could be on a second screen or tablet for the group to see between matches.
what i did
After a new match is validated and saved, I took each player’s individual performance and published the details to a redis pub-sub channel called “tetris:performances”. This could allow for a range of consumers each reacting to new matches in different ways.
When a new performance arrives I emit the details to any connected socket.io clients.
The first web client I made was a d3 scatterplot.
Points are added to the scatterplot in real time when they are submitted via the data entry app.
Check out the project code.
what would come next
More web clients consuming the websocket events. Or a dashboard of graphics each using the data in different ways or listening for subsets of the data.
A transcript showing the previous 10 matches.
Gathering context for the previous match. Run against a panel of db queries.
