A port of [Robotlegs SignalMediator Extension](https://github.com/MrDodson/robotlegs-extensions-SignalMediator) to TypeScript.

Originally published on [RobotlegsJS-SignalMediator](https://github.com/cuongdd2/RobotlegsJS-SignalMediator).

## Installation

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

```bash
npm install @robotlegsjs/pixi-signalmediator --save
```

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

```bash
yarn add @robotlegsjs/pixi-signalmediator
```

From version `0.2.0` of this package, the [PixiJS](https://github.com/pixijs/pixi.js) dependencies were moved to **peerDependencies**,
allowing the final user to choose the desired version of the `pixi.js` library on each project.

#### For `pixi.js` version 6

The `@robotlegsjs/pixi-signalmediator` package version `^4.0.0` is compatible with versions `>=6.0.0 <7` version range of `pixi.js` library.

You can setup your project for version 6 of `pixi.js` using:

```bash
npm install @robotlegsjs/pixi-signalmediator@^4.0.0 pixi.js@^6.0.0 --save
```

or

```bash
yarn add @robotlegsjs/pixi-signalmediator@^4.0.0 pixi.js@^6.0.0
```

#### For `pixi.js` version 5

The `@robotlegsjs/pixi-signalmediator` package versions `^2.0.0` and `^3.0.0` are compatible with versions `>=5.0.0 <6` version range of `pixi.js` library.

Since version `5.0.0` of `pixi.js`, the `eventemitter3` library was removed and is not necessary anymore.

You can setup your project for version 5 of `pixi.js` using:

```bash
npm install @robotlegsjs/pixi-signalmediator@^3.0.0 pixi.js@^5.0.0 reflect-metadata --save
```

or

```bash
yarn add @robotlegsjs/pixi-signalmediator@^3.0.0 pixi.js@^5.0.0 reflect-metadata
```

#### For `pixi.js` version 4

The `@robotlegsjs/pixi-signalmediator` package version `^1.0.0` is compatible with versions between the `>=4.2.1 <5` version range of `pixi.js` library.

Since each version of `pixi.js` library defines which version of `eventemitter3` library is being used, remember to also install the proper version of `eventemitter3` in your project.

As example, when you would like to use the version `4.2.1` of `pixi.js` library, you can run:

```bash
npm install @robotlegsjs/pixi-signalmediator@^1.0.0 pixi.js@4.2.1 eventemitter3@^2.0.0 reflect-metadata --save
```

or

```bash
yarn add @robotlegsjs/pixi-signalmediator@^1.0.0 pixi.js@4.2.1 eventemitter3@^2.0.0 reflect-metadata
```

Then follow the [installation instructions](https://github.com/RobotlegsJS/RobotlegsJS-Framework/tree/master/packages/core#installation) of **RobotlegsJS** library to complete the setup of your project.
