Installation

npm#

Javelin ECS can be installed via npm:

npm i @javelin/ecs

The following builds are published to NPM:

ES Modules#

Path: dist/esm/index.js

The package.json module field points to the ESM build, which will be automatically discovered by tools like Webpack, Rollup, and Node >=13.2.0.

import * as ECS from "@javelin/ecs"

You can of course also import the ES module directly in browsers that support ECMAScript modules.

<script type="module" src="node_modules/@javelin/ecs/dist/esm/index.js"></script>

CommonJS#

Path: dist/cjs/index.js

The package.json main field points to the CommonJS build, which will be included automatically when loaded with require:

const ECS = require("@javelin/ecs")
