# Elgato Light API
Control Elgato Key Lights and Light Strips with Javascript!

## Installation

Running `npm i elgato-light-api` will install the package. Typescript is natively supported.

## How to use

Create a new instance of `ElgatoLightAPI`:

```Javascript
const lightAPI = new ElgatoLightAPI();
```

An Event Emitter is used to notify listeners when a new Key Light is detected.
```Javascript
lightAPI.on('newLight', (newLight: KeyLight) => {
    console.log(newLight.name);
});
```

Currently, `ElgatoLightAPI` has two main functions, `updateLightOptions` and `updateAllLights`. And an exposed Array `keyLights`

#### UpdateLightOptions
```Javascript
lightAPI.updateLightOptions(lightAPI.keyLights[0], options).then(() => {
    console.log("Lights are all updated to the same value!");
}).catch(e => {
    console.error("Error: ", e);
});
```

#### UpdateAllLights
```Javascript
lightAPI.updateAllLights(options).then(() => {
    console.log("Lights are all updated to the same value!");
}).catch(e => {
    console.error("Error: ", e);
});
```
The interfaces required can all be found in [KeyLight.ts](https://github.com/NickParks/elgato-key-light/blob/master/src/types/KeyLight.ts)
