INTO THE ARCHITECTURE

.. AS EASY AS

Create the app manifest
Serve the manifest with .webapp
Appify the code.
Validate the markup
Publish the app

YES! YOU CAN !

Reuse any existing web site/app or develop from scratch with
open web standards.

Utilize HTML5 features such as localStorage, oﬄine manifest,
IndexedDB and access Web APIs for more options.

Responsive web design for adapting to varying resolutions and screen orientation.

var tel = navigator.mozTelephony


// Place a call
var cal = tel.dial('123456789')

WEB SMS

// SMS object
var sms = navigator.mozSMS

// Send a message
sms.send('123456789', 'Hello world!')

// Recieve a message
sms.onreceived = function (event) {
  console.log(event.message)
}

AUDIO && VIDEO

var p = navigator.mediaDevices.getUserMedia({ audio: true, video: true })

p.then(function(mediastream) {
   var video = document.querySelector('video')
   video.src = window.URL.createObjectURL(mediaStream)
   video.onloadedmetadata = function(e) {
      // Do something with the video here.
   }
}

p.catch(function(e) {
  console.log(e.name)
})

.. front camera?

var front = false
document.getElementById('flip-button').onclick = function() {
  front = !front
}

var constraints = { video: { facingMode: (front? 'user' : 'environment') } }

.. permissions

"permissions": {
  "audio-capture": {
    "description": "Required to capture audio using getUserMedia()"
  },
  "video-capture": {
    "description": "Required to capture video using getUserMedia()"
  }
}

ALARM API

if(navigator.mozAlarms) {
  var myAlarmDate  = new Date(month.value + ' ' + day.value + ', ' + year.value + ' ' + hours.value + ':' + minutes.value + ':00')
  var data = {
    task: title.value
  }  var request = navigator.mozAlarms.add(myAlarmDate, 'ignoreTimezone', data)
  request.onsuccess = function () {
    console.log('Alarm sucessfully scheduled')
    var alarmRequest = navigator.mozAlarms.getAll()
    alarmRequest.onsuccess = function() {
      newAlarmId = this.result[(this.result.length)-1].id
    }
   }
}

.. respond to alarm

if(navigator.mozSetMessageHandler) {
  navigator.mozSetMessageHandler('alarm', function (alarm) {

    if(alarm.data.task) {
      // Create a notification when the alarm is due
      new Notification(alarm.data.task)
      updateNotified(alarm.data.task)
    }
  })
}
