Web Install Meeting

This is to inform the WebApps Working Group that the Web Application Manifest editors met with representatives from Apple, Google, Microsoft, and Mozilla to discuss APIs to allow developers to programmatically open install dialogs for web sites. Web sites are already installable across all major engines and operating systems. The goal of this effort is to enable developers to advertise installation more prominently from within their viewport.

Here are the meeting minutes: https://docs.google.com/document/d/16OTq60o7pJMlQeO0KwuxzlMljsBZrt30LzpswQiP5Ko/edit

Summary:


  *
The meeting participants decided to split the conversation between installing the "current app," and installing "some app."
  *
The meeting participants favored the existing beforeinstallprompt event for solving the "current app" use case. There is a draft PR to re-introduce this event to the Manifest specification (https://github.com/w3c/manifest/pull/1206). Gecko and WebKit representatives have been asked to clarify their formal positions on supporting beforeinstallprompt (pending).
  *
Regarding "some app" installation, vendors are asked to clarify which install use-cases (same-origin, eTLD+1, cross-origin) they would be willing to support (pending).
  *
The Manifest editors will schedule a follow-up meeting with the participants in March.
