It received huge traffic in new years eve due to a reddit post I made in the /r/leagueoflegends subreddit.
It was crazy to see all the people going to my site. Every 10 min I would check google analytics to see how many users were viewing at the moment, 100, 200, 300 concurrent users, the numbers kept going up. I was happy to see how well the t2.micro instance performed. I kept the server light: It’s basically a proxy between the riot servers and the client. Later on I added some code to consume the API better, and only send what’s necessary to the front end.
My first reaction was of course: What is a Pascal Triangle? After reading wikipedia I said, ok let’s give it a try. At the end I didn’t make a function, but a whole ES6 class that renders it nicely to the browser.
