  10. 10. Some of the devices
  11. 11. A Firefox OS app? §  Creating a hosted or packaged app §  Using §  Vanilla HTML5 §  Librairies… §  Regular API §  Privileged API §  Certified API
  12. 12. HTML5 + manifest (JSON) = Firefox OS app { "version": “42", "name": ”My amazing app", "launch_path": "/index.html", "description": ”My super amazing app do super amazing things", "icons": { "16": "/images/logo16.png”,}, "developer": { "name": ”Frédéric Harper", "url": "http://outofcomfortzone.net", }, "default_locale": "en", "permissions": { "geolocation": { "description": ”Get the long/lat of the user" } } }
  13. 13. DEMO Firefox OS + App Manager + Emberjs todomvc

  20. 20. Battery Status var battery = navigator.battery; if (battery) { var batteryLevel = Math.round(battery.level * 100) + "%",   charging = (battery.charging)? “yes" : "no", chargingTime = parseInt(battery.chargingTime / 60, 10, dischargingTime = parseInt(battery.dischargingTime / 60, 10);   battery.addEventListener("levelchange", setStatus, false); battery.addEventListener("chargingchange", setStatus, false); battery.addEventListener("chargingtimechange", setStatus, false); }
  21. 21. Web APIs – Privileged •  Browser API •  Contacts API •  Device Storage API •  systemXHR •  TCP Socket API packaged
  22. 22. Browser
  23. 23. Browser <div> <span id='location-bar'></span> <button onclick='go_button_clicked()'>Go</button> </div> <div id='load-status'></div> <div id='security-status'></div> <img id='favicon'> <div id='title'></div> <iframe mozbrowser src=‘yoursite.com' id='browser'></iframe>
  24. 24.
