The Microsoft Edge API Surface

Microsoft Edge provides support for over 4300 standards-based open web APIs. Additionally, Microsoft Edge is part of the larger Universal Windows Platform (UWP) that powers Windows apps using JavaScript and HTML and also the HTML and XAML versions of the UWP WebView control. The Microsoft Edge API surface thus also includes specific features for building Windows apps.

Here you’ll find an index of the APIs currently supported in Microsoft Edge, as well as new APIs only available in the latest Windows Insider preview builds. Supported interfaces are described using the Web Interface Definition Language, Web IDL.
