Bringing the open web and APIs to mobile devices with Firefox OS - Whisky Web, Scotland

  1. 1. Bringing the Open Web & APIs to mobile devices with Firefox OS
  2. 2. @robertnyman
  3. 3. Firefox OS Using HTML5, CSS and JavaScript together with a number of APIs to build apps and customize the UI.
  4. 4. Open Web Apps
  5. 5. https://developer.mozilla.org/docs/Apps/Getting_Started
  6. 6. Steps to Take
  7. 7. Develop Web App using1. HTML5, CSS, & Javascript2. Create an app manifest file3. Publish/install the app
  8. 8. 1.Develop Web App usingHTML5, CSS & JavaScript
  9. 9. 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.
  10. 10. 2.Create an app manifest file
  11. 11. Create a file with a .webapp extension
  12. 12. { "version": "1.0", "name": "MozillaBall", "description": "Exciting Open Web development action!", "icons": { "16": "/img/icon-16.png", "48": "/img/icon-48.png", "128": "/img/icon-128.png" }, "developer": { "name": "Mozilla Labs", "url": "http://mozillalabs.com" }, "installs_allowed_from": ["*"], "appcache_path": "/cache.manifest", "locales": { "es": { "description": "¡Acción abierta emocionante del desarrollo del Web!", "developer": { "url": "http://es.mozillalabs.com/" } }, "it": { "description": "Azione aperta emozionante di sviluppo difotoricettore!", "developer": { "url": "http://it.mozillalabs.com/" } } }, "default_locale": "en"}
  13. 13. MANIFEST CHECKER http://appmanifest.org/
  14. 14. Serve with Content-type/MIME type:application/x-web-app-manifest+json
  15. 15. Apache - in mime.types:application/x-web-app-manifest+json webappApache - in .htaccess:AddType application/x-web-app-manifest+json webappNGinx - in mime.types:types { text/html html htm shtml; text/css css; text/xml xml; application/x-web-app-manifest+json webapp;}
  16. 16. IIS:In IIS Manager, right-click the localcomputer, and click Properties.Click the MIME Types button.Click New.In the Extension box, type the file nameextension.In the MIME type box, type a descriptionthat exactly matches the file type definedon the computer.Click OK.
  17. 17. curl -I http://mozillalabs.com/manifest.webapp
  18. 18. 3.Publish/install the app
  19. 19. Firefox Marketplace
  20. 20. https://marketplace.firefox.com/
  21. 21. https://marketplace.firefox.com/developers/
  22. 22. Installing/hosting the app
  23. 23. var request = navigator.mozApps.install( "http://mozillalabs.com/MozillaBall.webapp", { user_id: "some_user" });request.onsuccess = function() { // Success! Notification, launch page etc}request.onerror = function() { // Failed. this.error.name has details}
  24. 24. Packaged vs. Hosted Apps
  25. 25. A packaged app is an Open Web App that has all of its resources(HTML, CSS, JavaScript, app manifest, and so on) contained in a zip file, instead of having its resources on a Web server.A packaged app is simply a zip file with the app manifest in its root directory. The manifest must be named manifest.webapp.
  26. 26. Can be privileged apps with more API access than hosted appsResources are accessed from the zip file, which is stored on the device where theapp is installed)Enforce a specific Content Security Policy for all application contentCan embed remote content in iframes, but that content will not have access toprivileged APIs nor will it have the default CSP applied to it
