# JS Sensor

Sensor watcher of JavaScript sensor events.
This module is designed to have only basic functionality.
Any more complex functionality should be achieved through extending this module.

## Environment

Should work and be extensible using any new JavaScript environment(node, browser).
Default event listeners provided via browser-sensor-watcher.
Possible to use own via extension.

Currently uses Common JS due to not being limited to use on browser.
Can load via Common JS require OR by loading pre-built /dist/bundle.js.

## Build

If building from source is desired OR the latest dist is not provided, building can by done via `npm run build-all`

## Installation

1. Install node(including npm)
2. "npm install" in base directory

## Usage

The full api can be checked from the documentation. See "Documentation" below.

Basic usage can be seen below:

 ```javascript
 const jsSensor = new require('js-sensor');
 // OR Load via script element: <script src="js-sensor/dist/bundle.js"></script>

 // Get sensor list
 console.log('names:' jsSensor.getMappedSensorNames());

 // Update/extend
 jsSensor.updateSensorListeners((sensorListenerMap)=>{
     sensorListenerMap['myListener'] = {
         start: (options)=>{
             const data = '...HANDLE HERE';
             options.events.data(data);
         },
         stop: ()=>{
             // STOP
         },
         check: ()=>{
             // CHECK FOR AVAILABILITY
             return true;
         }
     };
     return sensorListenerMap;
 });

 // Get
 jsSensor.get('deviceMotion')
 .then((data)=>{
     console.log('get', data);
 });

 // Watch
 jsSensor.watch('deviceOrientation',
 {
     events: {
         data: (data)=>{
             console.log('watch', data);
         }
     }
 });

 // Stop
 jsSensor.stop('deviceOrientation);

 // WatchAll
 jsSensor.watchAll();
 // ...wait a while
 // StopAll
 jsSensor.stopAll()
 ```
