The classic NES Tetris built with hyperapp

I recently got quite hooked on watching the CTWC. This inspired me to go try build the game Tetris for myself in order to better understand the game. There has been talk on the hyperapp slack about creating a project – working application built with hyperapp – that we can use to dogfood new ideas and serve as a reference when creating new apps.

The idea of a game came up and it seemed like a good theme to run with; limited enough in scope but complex enough to stress test design patterns and perf. I wanted to implement a dependency and build step free project as to put focus mostly on the application code as well as structure.

A lot of the code has been copied and adapted from two codepens:

• Falling blocks by Zacharias Enochsson built with Hyperapp V1
• Saigon Racer by Luke Jackson built with Hyperapp V2

The application currently looks like this and you can play it online here:

This project has been left unoptimized in places. There is a lot of low hanging fruit when it comes to features or details to add. The aim is to replicate the classic NES version as closely as possible for fun!
