Lanchnation is a group of friends with a friendly sport betting pool, with the website showing who is having the best season, etc.
Lanchnation uses Google Sheets as a database, pulling the information on every reload, displaying the current and future bets, along with an auto-updating leaderboard. On the front end it is built with Vue's CLI and ES6.
I wrote a much more extensive article here on how I set up Google Sheets as the database.
