Sync on projects of shared interest

  • Microsoft Lead:

    • Web Install Umbrella bug, UX bug, Discussion doc

      • Very close to OT! (hoping for 143, otherwise 144)

      • Use of the API will not require the site to be installed as a web app

      • FYI – mkwst landed a semi-functional prototype for PEPC

        • [<install> Element] Build a prototype. (7079238) · Gerrit Code Review

        • Uses hostname as a unique identifier – likely not viable

          • Want to parse manifest to gather name

          • Few topics:

            • What expectations about continued work on PEPC Install element prototype?

            • Reviews by liahi...@microsoft.com & Krist...@microsoft.com for interaction with permission.

            • Open questions:

              • What if there’s a page with high number of install elements, does that spawn ~50 background manifest requests (Possibly requires creating a web contents, then loading start URL)? Caching may not be effective in an app store context where there is significant new content.

      • AI: Dan Murphy take a task to ask partners to try the install API during origin trial.

      • Can we include PEPC in current OT?

        • That would delay quite a bit.

      • What questions do we want to ask from OT app partners? (see explainer)

      • Blogpost to explain manifest ID

Sync on projects of shared interest

  • Microsoft Lead:

    • Web Install Umbrella bug, UX bug, Discussion doc

      • Thank you so much for your help with the security conversations and other internal discussions!

      • Good news - Privacy approval (in addition to Security) for Origin Trial.

      • Gating install behind installation (requiring the site that wants to install other web apps, to be installed by the user first) - based on conversation with mkwst@ (Email Re: WebInstallApi Security Review followup - Thursday, August 28)

        • Partners expressed requiring install would be a deal breaker.

          • TODO Vince have PWA team check with partners we’re in contact with.

        • Vince - in the past, gating behind installation was for capabilities that were clearly tied to the concept of being installed (ex - taskbar icon), but the line isn’t super solid. Web install is related to installation, but arguments could be made either way

        • Spectrum

          • Existing on OS Taskbar or Dock

          • File Handling

          • … current “install required” line drawn here ...

          • Notifications

          • Geolocation

        • Install (in Vince’s opinion) is near the boundary, and could certainly work from non-install.

        • .NET ClickOnce - Users can install applications by simply clicking a link on a webpage, a network share, or from local media. This eliminates the need for complex setup procedures often associated with traditional installers.
