A comprehensive and high-performance Entity Component System (ECS) framework written in TypeScript, designed for building games, simulations, and interactive applications.

OrionECS provides a modern, type-safe approach to component-based architecture with a focus on performance and developer experience. Whether you're building a game engine, simulation system, or any application that benefits from composition over inheritance, OrionECS has you covered.

• Efficient Entity Management - Object pooling and optimized component storage
• Advanced Query System - Support for ALL, ANY, and NOT queries with tag-based filtering
• Priority-Based Systems - Configurable execution order with lifecycle hooks
• Component Archetypes - Improved cache locality for better performance
• Memory Management - Automatic pooling with built-in profiling and metrics
• Change Detection - Component versioning for selective updates
• Entity Relationships - Parent/child hierarchies with automatic cleanup
• Plugin System - Extensible architecture for custom features
• Prefabs - Template-based entity creation
• Serialization - World state snapshots for save/load functionality

npm install @orion-ecs/core

import { EngineBuilder } from '@orion-ecs/core';

const game = new EngineBuilder()
  .withFixedUpdateFPS(60)
  .withDebugMode(true)
  .build();

game.createSystem('MovementSystem', {
  all: [Position, Velocity],
  tags: ['active']
}, {
  priority: 10,
  act: (entity, position, velocity) => {
    position.x += velocity.x;
    position.y += velocity.y;
  }
});
