Project Fugu: Progressive Web Apps, Superpowered

Project Fugu: Progressive Web Apps, Superpowered

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 superpower your Progressive Web App?

    Project Fugu – A More Capable Web »Let’s bring the web back – API by API« Thomas Steiner, Google

  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, Superpowered 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? Project Fugu Progressive Web Apps, Superpowered Project Fugu

    'http://example.com' }); ShareIntent DataTransferManager … NSSharingServicePicker

    }); } else { // Fallback method } Project Fugu Progressive Web Apps, Superpowered Project Fugu
  11. Badging API Project Fugu Progressive Web Apps, Superpowered

  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
  13. API Set the badge navigator.setAppBadge(5); Clear the badge navigator.clearAppBadge(); Project

  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
  16. 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
  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 of 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/
  20. Shape Detection API Project Fugu Progressive Web Apps, Superpowered

  21. Faces Barcodes Text Use Cases Project Fugu Progressive Web Apps,

    Superpowered 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, Superpowered Shape Detection API

  26. Async Clipboard API Project Fugu Progressive Web Apps, Superpowered

  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, Superpowered Async Clipboard API
  28. File System Access API Project Fugu Progressive Web Apps, Superpowered

  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, Superpowered 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, Superpowered 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, Superpowered File System Access API

  34. - Project Fugu helps the web to become more and

    more capable - Project Fugu APIs could bring many more app experiences to the web (IDEs, productivity apps, etc.) - But: Web is threatened by alternative approaches and platforms, support for modern Web API varies from platform to platform - You can make a difference! - File bugs in browser engine bugtrackers - File Fugu requests: https://goo.gle/new-fugu-request Project Fugu Progressive Web Apps, Superpowered Summary
