  • 1. Web application stores in GNOME José Dapena Paz <jdapena@igalia.com>
  • 2. Web application stores in GNOME 2 Step 1: integrate any web application in desktop ● Achieved with Epiphany “Save as Web Application” Webs saved by user are shown as toplevel desktop applications. ● Jose Dapena Paz | jdapena@igalia.com | www.igalia.com
  • 3. Web application stores in GNOME 3 Step 2: web application stores. Do we need to support them? ● GNOME is not a big target for developers. ● Web apps are. ● Apps stores are not the key, but the apps themselves. – – ● We need to support the technologies they use. App stores just give a good visibility to the applications. Users want apps fiting their specific needs: – The more app platforms we support, the more likely we match user needs. Jose Dapena Paz | jdapena@igalia.com | www.igalia.com
  • 4. Web application stores in GNOME 4 Experiment: Epiphany support for Chrome web Store and Mozilla OpenWebApps Available at https://github.com/jdapena/epiphany/tree/webapp Jose Dapena Paz | jdapena@igalia.com | www.igalia.com
  • 5. Web application stores in GNOME 5 Results: Chrome Web Store API is not public. Any change in their APIs would break Chrome web store support. ● ● Some apps use specific Chrome APIs. – Not many, but store API's do not report that information. Final user perception: apps randomly fail. No real good support. They'll drop Epiphany and adopt Chrome. ● ● What to do? We won't play a game of cat and mouse. Jose Dapena Paz | jdapena@igalia.com | www.igalia.com
  • 6. Web application stores in GNOME 6 Results: Mozilla marketplace ● Still not available. Expected for this year. ● API's discussion and specs are publicly available. ● Some of them already sent to W3C. ● What to do? Support it. Jose Dapena Paz | jdapena@igalia.com | www.igalia.com
  • 7. Web application stores in GNOME 7 Implementation challenges: Web stores support is basically implementing some javascript API's that map to Epiphany applications support (applications list, permissions and UI for install/uninstall). ● Experiment implementation based on WebKit-GTK+ JavaScriptCore API. We get access from GTK+ code to the web javascript contexts. ● Epiphany is targetting WebKit2. No direct exposure of web javascript contexts. ● Jose Dapena Paz | jdapena@igalia.com | www.igalia.com
  • 8. Web application stores in GNOME 8 But the key that will make the difference is supporting the new HTML5 features apps will use. – New graphic features (CSS3, WebGL, …). – New types of form inputs (phone, email, date/time, …). – Video and audio streaming, RTC, use media streams as form inputs. – Hardware and desktop integration (battery, geolocation, full screen, device orientation, notifications, web intents, other sensors). This work goes mainly on WebKit and WebKit-GTK+ Jose Dapena Paz | jdapena@igalia.com | www.igalia.com
  • 9. Web application stores in GNOME 9 Goal: OpenWebApps stores support in Epiphany. Target: Q2 2013. Any help is warmly welcome. But: Apps store support RELY heavily on implementing HTML5 new standards. ● Roadmap needs to be updated. ● Jose Dapena Paz | jdapena@igalia.com | www.igalia.com
  • 10. Web application stores in GNOME 10 Goal: OpenWebApps stores support in Epiphany. Target: Q2 2013. Any help is warmly welcome. But: Apps store support RELY heavily on implementing HTML5 new standards. Roadmap needs to be updated. Jose Dapena Paz | jdapena@igalia.com | www.igalia.com
