$ show TheOrcDev/8bitcn-ui
This repository is a Next.js application that serves both as a documentation site and a registry server for a retro 8-bit styled UI component library, built on top of shadcn/ui primitives. It provides dozens of copy-paste components (buttons, cards, dialogs, health bars, etc.) and pre-built page blocks (heroes, features, pricing, gaming HUDs) distributed via a shadcn-style registry (`shadcn add @8bitcn/...`). The project also includes two full, playable arcade games (Brick Breaker and Crate Pusher) used as creative 404 pages, with well-tested, deterministic game engines. The codebase demonstrates strong engineering practices: pure immutable game state reducers, fixed-timestep physics, accessibility-focused UI, and a custom cold-path benchmarking harness used to optimize development compilation times by 27.7%. The architecture is a monorepo-like structure within a single Next.js app, with the component library living as source files that are copied into user projects via the registry mechanism.
The LLM identified 4 files worth highlighting for reuse:
A complete, pure-function Sokoban (crate pusher) game engine implemented as an immutable state reducer. Handles level parsing, player movement, push logic, undo, reset, and win detection. Uses a seeded shuffle bag for level ordering. Fully tested with Vitest. Could be extracted into any JavaScript/TypeScript project with no dependencies on the rest of the codebase.
A fixed-timestep arcade brick-breaker game engine with swept ball-to-brick collision detection, paddle physics, lives, scoring, and an event system for UI integration. Implemented as pure functions over an immutable game state. Extensively unit tested. Demonstrates careful physics simulation and is reusable independently of this project's UI.
A clean React hook that uses IntersectionObserver to detect when an element is near the viewport (configurable rootMargin). Disconnects the observer after first intersection, preventing unnecessary work. Isolated and can be reused in any React project for deferred loading of components or assets.
A standalone Node.js script that measures cold-start compilation times of a Next.js development server for a specific route. Saves and restores the `.next` cache between runs to ensure accurate cold measurements. Computes percentiles (p50, p90, etc.) and outputs structured results. Not coupled to this project's UI and can be reused as a general Next.js dev performance diagnostic tool.
