This repository is a monorepo containing the frontend and backend code for the Hack4Krak website. The frontend is built with Nuxt and the backend is built with Rust. The two parts are connected via a REST API.
For documentation refer to specific DEVELOPMENT.md files:
The production website is currently fully self-deployed on a VPS with Dokploy.
