Typescript support

[eranimo]

Would be great.

Also, would it be possible to define a component as a Typescript interface?

I have some rough typings. Feel free to use them or I can tidy up them up and make a PR if the author wants them?

That link is dead now - here's the typings:

// entity-component-system.d.ts
declare module "entity-component-system" {
	export class EntityComponentSystem {
		constructor();
		add(system: System): void;
		addEach(system: System, search: string): void;
		run(entityPool: EntityPool, elapsedTime: number): void;
		runs(): number;
		timings(): { [key: string]: number };
		resetTimings(): void;
	}

	export class EntityPool {
		constructor();
		create(): number;
		destroy(id: number): void;
		registerComponent<Component>(
			component: string,
			factory: () => Component,
			reset?: (component: Component) => void,
			size?: number,
		): void;
		addComponent<Component>(
			id: number,
			component: string,
		): Component;
		getComponent<Component>(
			id: number,
			component: string,
		): Component;
		setComponent<Component>(
			id: number,
			component: string,
			value: Component
		): void;
		onAddComponent<Component>(
			component: string,
			callback: Callback<Component>
		): void;
		onRemoveComponent<Component>(
			component: string,
			callback: Callback<Component>
		): void;
		registerSearch(
			search: string,
			components: string[]
		): void;
		find(
			search: string,
		): number[];
		load(entities: EntityJson[]): void;
		save(): EntityJson[];
	}

	export interface System {
		(entityPool: EntityPool, elapsedTime: number): void
	}

	export interface Callback<Component> {
		(id: number, component: string, value: Component): void;
	}

	export interface EntityJson {
		id: number,
		[componentName: string]: any
	}
}
