Triangulate.xyz

This was the source code for Triangulate.xyz which allows you to create computer generated art.

I created this project to learn ReactJS, this was my first project. I also wanted to make a backend in Golang and learn how to integrate Stripe for payments.

Begin by copying the .example.env file to .env and make any needed changes. To run the project simply type the following in the root folder:

yarn --cwd=assets build && go run cmd/triangulate/main.go

This project takes a lot of concepts and code from generative-art-in-go and triangle.
