Project Fugu: Progressive Web Apps, Superpowered

Project Fugu: Progressive Web Apps, Superpowered

Progressive Web Apps sind ein großartiges, plattformübergreifendes Anwendungsmodell. Als webbasierte Plattform gab es funktional aber einige Einschränkungen – zumindest bis jetzt. Die Initiative Project Fugu, der unter anderem Google, Microsoft und Intel angehören, hat ein klares Ziel: Ein leistungsfähigeres Web! Die von Project Fugu eingeführten APIs erlauben Zugriff auf Zwischenablage, Dateisystem und viele weitere bislang ausschließlich nativ verfügbare Schnittstellen. In dieser Session stellt Ihnen Christian Liebel, PWA-Experte bei Thinktecture, die Eckpunkte von Project Fugu vor und zeigt Ihnen einige APIs. So bekommt Ihre PWA neue Superkräfte!

  12. Motivation - Communicate updates without distracting the user (in constrast

    to push notifications) - Typically displays a badge on the home screen, task bar or dock - Appearance varies from platform to platform Project Fugu Progressive Web Apps, Superpowered Badging API

  14. Shortcuts Project Fugu Progressive Web Apps, Superpowered

  15. Provide secondary entry points for your application, now also for

    Progressive Web Apps added to the home screen Windows: Jump List iOS: Home Screen Quick Actions Project Fugu Progressive Web Apps, Superpowered Shortcuts

  17. Screen Wake Lock Project Fugu Progressive Web Apps, Superpowered

  18. Motivation - Devices go to sleep in order to reduce

    energy consumption - However, this can get bothersome in some situations (e.g. while watching a movie, while cooking, etc.) - The Screen Wake Lock API prevents the device from turning off the screen while the application has the wake lock Project Fugu Progressive Web Apps, Superpowered Screen Wake Lock API
  19. API let wakeLockObj; if ('wakeLock' in navigator) { try {

    wakeLockObj = await navigator.wakeLock.request('screen'); console.log('👍', 'Screen Wake Lock', wakeLockObj); } catch (err) { console.error('👎', 'Screen Wake Lock', err); } } Project Fugu Progressive Web Apps, Superpowered Screen Wake Lock API https://web.dev/wake-lock/

  24. API if ('showOpenFilePicker' in window) { const [handle] = await

    window.showOpenFilePicker(); const file = await handle.getFile(); // do something with the file } else { // use fallback API or disable feature in app } Project Fugu Progressive Web Apps, Superpowered File System Access API
  25. API const [handle] = await self.showOpenFilePicker({ multiple: true, types: [{

    description: 'PNG files', accept: {'image/png': ['.png']} }] }); Project Fugu Progressive Web Apps, Superpowered File System Access API
  26. File System Handling API Project Fugu Progressive Web Apps, Superpowered

  27. Motivation Register your PWA as a handler for file extensions

    Requires installing the application first Declare supported extensions in Web App Manifest and add imperative code to your application logic Project Fugu Progressive Web Apps, Superpowered File System Handling API
  28. Manifest Extension { "file_handlers": [{ "action": "/", "accept": { "image/png":

    [".png"] } }] } Project Fugu Progressive Web Apps, Superpowered File System Handling API
