How to use

It all revolves around the EmotionTracker class.

First install this library

npm install 'emotion-tracker-js'

Import and initialize our tracker!

import EmotionTracker from 'emotion-tracker-js'

let emotionUpdateCallback = () => {}

let emotionTracker = new EmotionTracker(emotionUpdateCallback)
emotionTracker.track()
// You need to take the pictures and establish the connection with the webcam and use that
// ... Webcam code that takes picture
let emotion = emotionTracker.poll(imageFile)
// As soon as the api request is resolved, the callback you specified will be called '
// and you will have access to the newest emotion state of the user. You can use the variable emotion as well.

Callbacks and State Management

This npm module exports a main class EmotionTracker which uses javascript proxies by which the user will be notified each time the user's emotion changes. Developers can easily abstract their functionality into a callback which accepts the following arguments

function myCallback(key, value, target) {
    // do whatever you want with these
}

The callback is invoked with the parameters of the property that is changed in the emotion state object as well as the value it is taking.
