Project Fugu: Progressive Web Apps, Taken to The Next Level

Progressive Web Apps are a great cross-platform application model, even if somewhat restricted in use—until now, that is. Project Fugu is an initiative led by Google, Microsoft, and Intel. Their goal: a more capable web. Home screen icon badges and shortcuts, clipboard access, accelerated shape detection in images and native file system access are only a few examples of Fugu’s powerful APIs. In this session, Christian Liebel, PWA specialist at Thinktecture, shows you the objective of Project Fugu and demonstrates some of its APIs. Are you ready to take your Progressive Web App to the next level?

7. Process – Write an Explainer (https://github.com/WICG/native-file- system/blob/master/EXPLAINER.md) – Discuss capability with developers, browser vendors, standard orgs – Iterate – Compile a design document – W3C TAG Review (https://github.com/w3ctag/design- reviews/issues/390) – Formal spec within Web Incubator Community Group (WICG, https://wicg.github.io/native-file-system/) Project Fugu Progressive Web Apps, Taken To The Next Level Project Fugu
8. Process – Implementation in Chromium – Launches behind a flag (chrome://flags/#enable-experimental-web- platform-features) – Origin Trial (https://developers.chrome.com/origintrials/) – Transfer to W3C Working Group + Recommendation?

11. Badging API Project Fugu Progressive Web Apps, Taken To The Next Level
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, Taken To The Next Level Badging API
13. API Set the badge navigator.setAppBadge(5); Clear the badge navigator.clearAppBadge(); Project Fugu Progressive Web Apps, Taken To The Next Level Badging API
14. Shortcuts Project Fugu Progressive Web Apps, Taken To The Next Level
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, Taken To The Next Level Shortcuts
16. Web App Manifest Extension { "shortcuts": [ { "name": "Direct Messages", "url": "/mails/new", "icons": [] }, { "name": "Notifications", "url": "/appointments/new", "icons": [] } ] } Project Fugu Progressive Web Apps, Taken To The Next Level Shortcuts
17. Screen Wake Lock Project Fugu Progressive Web Apps, Taken To The Next Level
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 of the screen while the application has the wake lock Project Fugu Progressive Web Apps, Taken To The Next Level 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, Taken To The Next Level Screen Wake Lock API https://web.dev/wake-lock/
20. Shape Detection API Project Fugu Progressive Web Apps, Taken To The Next Level
21. Faces Barcodes Text Use Cases Project Fugu Progressive Web Apps, Taken To The Next Level Shape Detection API
22. Face Detection API if ('FaceDetector' in window) { const img = document.querySelector('img'); const faceDetector = new FaceDetector(); const faces = await faceDetector.detect(img) faces.forEach(face => { console.log('Face found!', face.boundingBox); }); } Project Fugu Progressive Web Apps, Taken To The Next Level Shape Detection API

26. Async Clipboard API Project Fugu Progressive Web Apps, Taken To The Next Level
27. 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, Taken To The Next Level Async Clipboard API
28. File System Access API Project Fugu Progressive Web Apps, Taken To The Next Level
29. 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, Taken To The Next Level File System Access API
30. 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, Taken To The Next Level File System Access API
31. API const [handle] = await self.showOpenFilePicker({ multiple: true, types: [{ description: 'PNG files', accept: {'image/png': ['.png']} }] }); Project Fugu Progressive Web Apps, Taken To The Next Level File System Access API
