New version of the Roadmap of Web Applications on Mobile

7 August 2018 | Archive

W3C has published a new version of its Roadmap of Web Applications on Mobile, an overview of the various technologies developed in W3C that increase the capabilities of Web applications, and how they apply more specifically to the mobile context.

The contents of the roadmap have been updated to follow the evolution of the Web platform since April 2018. See the Change history for details. Most of these updates focused on mechanisms that allow mobile web applications to tweak performance settings and gain finer-grained control over the browser’s default behavior. In particular, new exploratory work and technologies in progress mentioned in the Performance and Tuning page include:

  • the CSS Animation Worklet API to create scripted animations in a dedicated thread,
  • the CSS contain property to indicate that an element’s subtree is independent of the rest of the page,
  • the proposed CSS overscroll-behavior property to control the behavior of a scroll container when its scrollport reaches the boundary of its scroll box,
  • the Event Timing Web Perf API to measure the latency of events triggered by user interaction,
  • leisure Christopher Banks Jacket amp; Boutique HwTqOFxg
  • the Identifiers for WebRTC’s Statistics API to monitor the performance of the network and media pipeline in peer-to-peer scenarios, and
  • Priority Hints to let developers signal the priority of each resource they need to download.

The roadmap did not mention WebDriver, recently published as a W3C Recommendation, a key technology for mobile web developers as it enables automated testing across browsers and devices. This was an oversight, fixed in this new version.

The implementation info rendered in tables now also embeds information from the MDN Browser Compatibility Data project. A new “partial” badge also indicates that an implementation may be incomplete, either because it is, or because implementation data is not complete enough to assess support of the entire specification.

Sponsored by Beihang University, this project is part of a set of roadmaps under development in a GitHub repository to document existing standards, highlight ongoing standardization efforts, point out topics under incubation, and discuss technical gaps that may need to be addressed in the future. New versions will be published on a quarterly basis, or as needed depending on progress of key technologies of the Web platform. We encourage the community to review them and raise comments, or suggest new ones, in the repository’s issue tracker.
