Project Fugu: Progressive Web Apps, Superpowered

Over the last decade, the web has advanced to be a robust application platform. Most recently, Progressive Web Apps have brought native capabilities to the web. But that’s not the end of the story! Project Fugu, a cross-vendor initiative by Google, Microsoft, and Intel, aims to bring even more native capabilities to the web—native file system and clipboard access, accelerated shape detection in images, home screen icon badges and shortcuts included! Christian Liebel, PWA specialist at Thinktecture, shows you the objective of Project Fugu and demonstrates some of its APIs.

10. Badging API Project Fugu Progressive Web Apps, Superpowered
11. 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
12. API Set the badge navigator.setAppBadge(5); Clear the badge navigator.clearAppBadge(); Project Fugu Progressive Web Apps, Superpowered Badging API
13. Shortcuts Project Fugu Progressive Web Apps, Superpowered
14. Web App Manifest Extension { "shortcuts": [ { "name": "Direct Messages", "url": "/mails/new", "icons": [] }, { "name": "Notifications", "url": "/appointments/new", "icons": [] } ] } Project Fugu Progressive Web Apps, Superpowered Shortcuts
15. Screen Wake Lock Project Fugu Progressive Web Apps, Superpowered
16. 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
17. 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/
18. Async Clipboard API Project Fugu Progressive Web Apps, Superpowered
19. API Copy Content await navigator.clipboard.writeText('foo'); await navigator.clipboard.write(/* data */); Paste Content const content = await navigator.clipboard.readText(); const content = await navigator.clipboard.read(); Project Fugu Progressive Web Apps, Superpowered Async Clipboard API
20. File System Access API Project Fugu Progressive Web Apps, Superpowered
21. Motivation - Currently, websites only have very limited access to the file system - Some applications heavily rely on working with files (e.g. Visual Studio Code) - Wouldn’t it be great if your web application could open files or folders from the native file system? Project Fugu Progressive Web Apps, Superpowered File System Access API
22. 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
23. 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
24. File System Handling API Project Fugu Progressive Web Apps, Superpowered
25. 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
26. Manifest Extension { "file_handlers": [{ "action": "/", "accept": { "image/png": [".png"] } }] } Project Fugu Progressive Web Apps, Superpowered File System Handling API
27. API if ('launchQueue' in window) { launchQueue.setConsumer(async params => { const [handle] = params.files; // do something with the handle }); } Project Fugu Progressive Web Apps, Superpowered File System Handling API

29. New powerful APIs regularly ship with new releases of Chromium-based browsers Some only add minor finishing touches, others enable whole application categories as productivity apps to finally make the shift to the web Some APIs already made their way into other browsers (e.g., Web Share) Fugu process makes sure that capabilities are implemented in a secure, privacy-preserving manner Let’s make the web a more capable platform!
