Specification

https://html.spec.whatwg.org/#dom-navigationtransition-to

Summary

Currently NavigationTransition has a "from" property, exposing the old URL of the navigation. Exposing "to" (a NavigationDestination) completes this. It is especially useful when using precommit handlers, as during precommit the current URL has not yet switched to the destination. Note that navigation.transition is only exposed for intercepted navigations - which means same-origin document-initiated navigations.

Motivation

Exposing things in navigation.transition helps curating the navigation experience without having to listen to *all* navigation events. Specifically, the to/from properties of navigation.transition map nicely to the to/from route matchers (see https://github.com/WICG/declarative-partial-updates/blob/main/route-matching-explainer.md)

Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
