Node server and react app to synchronize video across devices.
After cloning the repo, run yarn.
In src/api.js, update const socket = openSocket('http://10.1.17.188:8000'); to your computer's address on the local netowrk. (When you yarn start the react app, it gives you this url.)
Run node server.js to start the socket.io server.
Run yarn start to run the react app.
Then, you can visit the url from any device on the local network. The controller should be subscribed first, then any number of displays can be added.
Click "Sync Video" button to restart all the videos simultaneously.
