Make WebView great again!

When developing Universal Windows Platform (UWP) apps for Windows 10 one of the core elements developers often use is the WebView. It's a control designed for displaying Web Pages, either from local or any online source. It's basically a Frame for rendering HTML content powered by the EdgeHTML rendering core.

The WebView went through many iterations since its conception in Windows 8 in late 2012. It went from hard to use always-on-top element powered by IE10 Trident Core to a modern and quite capable control supporting current HTML5 standards and modern HTTPS cipher suites.

From a developers' point of view lot of useful methods and settings was added in the Windows 10 version of WebView, for instance event handlers to allow access to Geolocation API or Webcam, detection when the website wants to open a new window, notification about loading state od each Frame, possibility to provide native object which is then available from the page DOM, and much more.

Unfortunately, the WebView, as it's available today, is still incomplete in terms of usability and does not provide several critical APIs. In this article I have gathered the most important missing or incomplete WebView features that would make the WebView finally a first class citizen, or great again.

I sorted these features into three groups:

  • Must fix are critical security and/or functional features that cannot be implemented using any workaround
  • Should fix are features, that would make the WebView much easier to use, but are not critical for daily use or can be implemented using nontrivial workarounds, like JavaScript injection and notification back to the app
  • Nice to haves are optional improvements for making developer more happy 🙂

Note that all missing features requested below are already available in the Microsoft Edge browser. I’m not requesting something, that is not yet available in the EdgeHTML core for obvious reasons.
