Craters is a modular JavaScript framework reimplemented in TypeScript for rapid HTML5 game development. Built around the Entity-Component-System (ECS) pattern, it gives developers a clean, composable foundation for browser-based games without engine lock-in.

Features:

• Entity Component System (ECS) — World, Entity, System, Query for managing all game logic
• Collision Detection — SAT (Separating Axis Theorem) for circles and convex polygons; QuadTree for broad-phase spatial partitioning
• Rendering — WebGL sprite batching renderer + Canvas2D fallback with primitive drawing
• Input — Unified keyboard, mouse, and touch handling via KeyboardEvent.code
• Sound — Web Audio API wrapper for effects and music
• Asset Management — Simple loader for images and resources
• Tilemaps — Load and render tilemap data

Install:

npm install craters
