HIQaH! QaH! TAG!

I'm requesting a TAG review of Declarative Link Capturing for Progressive Web Apps.

New Web App Manifest members to control what happens when the user navigates to a page within scope of an installed web app.

This feature introduces the "capture_links" member, an enumeration allowing the customization of link capturing behaviour, allowing sites to:

• Automatically open a new PWA window when the user clicks a link to their app.

• Have a "single window mode" like mobile apps.

  • Explainer¹ (minimally containing user needs and example code): https://github.com/WICG/sw-launch/blob/master/declarative_link_capturing.md
  • Security and Privacy self-review²: Google Doc
  • GitHub repo (if you prefer feedback filed there): https://github.com/WICG/sw-launch
  • Primary contacts (and their relationship to the specification):
    • Matt Giuca (@mgiuca), Google
  • Organization/project driving the design: Google
  • External status/issue trackers for this feature (publicly visible, e.g. Chrome Status): https://www.chromestatus.com/feature/5734953453092864

Further details:

• I have reviewed the TAG's API Design Principles
• The group where the incubation/design work on this is being done (or is intended to be done in the future): WICG
• The group where standardization of this work is intended to be done ("unknown" if not known): Web Apps WG
• Existing major pieces of multi-stakeholder review or discussion of this design:
• Major unresolved issues with or opposition to this design:
• This work is being funded by: Google

This is a sibling spec to URL Handler which would allow link capturing from different origins and URLs outside of the app scope. We are collaborating with Microsoft (the primary authors of URL Handler) to make sure these two projects fit nicely with one another.

We'd prefer the TAG provide feedback as (please delete all but the desired option):
