RobotlegsJS is a architecture-based IoC framework for JavaScript/TypeScript. This
version is a direct port from the [ActionScript 3.0 codebase](https://github.com/robotlegs/robotlegs-framework).
See the [motivation](#motivation) behind it.

Right now, this framework has extensions for [pixi.js v5](https://github.com/pixijs/pixi.js), [easeljs](https://github.com/CreateJS/EaselJS),
[openfl](https://github.com/openfl/openfl), [phaser-ce v2](https://github.com/photonstorm/phaser-ce) and [phaser v3](https://github.com/photonstorm/phaser).

## Installation

You can get the latest release and the type definitions using [NPM](https://www.npmjs.com/):

```bash
npm install @robotlegsjs/core reflect-metadata --save
```

Or using [Yarn](https://yarnpkg.com/en/):

```bash
yarn add @robotlegsjs/core reflect-metadata
````

> :warning: **Important!** RobotlegsJS requires TypeScript >= 2.0 and the `experimentalDecorators`, `emitDecoratorMetadata`, `types` and `lib`
compilation options in your `tsconfig.json` file.

```js
{
    "compilerOptions": {
        "target": "es5",
        "lib": ["es6", "dom"],
        "types": ["reflect-metadata"],
        "module": "commonjs",
        "moduleResolution": "node",
        "experimentalDecorators": true,
        "emitDecoratorMetadata": true
    }
}
```

RobotlegsJS requires a modern JavaScript engine with support for:

- [Reflect metadata](https://rbuckton.github.io/reflect-metadata/)
- [Map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map)

If your environment doesn't support one of these you will need to import a shim or polyfill.

> :warning: **The `reflect-metadata` polyfill should be imported only once in your entire application** because the Reflect object is meant to be a global singleton. More details about this can be found [here](https://github.com/inversify/InversifyJS/issues/262#issuecomment-227593844).

Check out the [Environment support and polyfills](https://github.com/inversify/InversifyJS/blob/master/wiki/environment.md)
page in the [InversifyJS](https://github.com/inversify/InversifyJS) wiki and their [Basic example](https://github.com/inversify/inversify-basic-example) to learn more.

To learn more about the basic usage and APIs provided by [InversifyJS](https://github.com/inversify/InversifyJS), follow [The Basics](https://github.com/inversify/InversifyJS/blob/master/README.md#the-basics) and [The InversifyJS Features and API](https://github.com/inversify/InversifyJS#the-inversifyjs-features-and-api).

## Motivation

There are many frameworks and patterns out there that helps you to write
DOM-based applications. There is no scalable solution yet to architecture a
canvas-based application though.

[Robotlegs](https://github.com/robotlegs/robotlegs-framework) has proven itself of being a mature solution from the ActionScript
community for interactive experiences.
