WICG/manifest-incubations

Before install prompt API for installing web applications

Specification 'manifest-incubations'

Specification link: https://wicg.github.io/manifest-incubations/index.html

Explainers

• Scope Extensions for Web Apps

Background

There are a number of Web App Manifest features that are either not mature enough to go into the main W3C spec, or that do not belong there because they do not have multiple independent implementations.

• BeforeInstallPrompt
• display_override (unless that PR can land in W3C Manifest)
• Tabbed mode
• Protocol handlers
• Declarative link capturing

Rather than creating a separate WICG repo for each of these (given that there are often interdependencies between them), we are creating a "manifest-incubations" spec with all of them in a single document. That means readers only need to keep track of two documents, instead of ~10.

Other related incubations that do have their own WICG repos:

• URL handlers
• File handlers
• Window controls overlay

Despite this, it may make sense for their spec text to live inside manifest-incubations since they may have dependencies on other things here (e.g., display_override).
