APIs that are missing from the web

The convergence of web and mobile applications has been accelerated by the development of Progressive Web Apps (PWAs), which offer a native-like experience and leverage APIs to access mobile device capabilities. Despite this progress, there are several APIs that remain exclusive to native apps, such as those for file systems, contacts, biometrics, geofencing, messaging, NFC, wake locks, Bluetooth, and sensors. These APIs allow for enhanced interactions, like accessing device files, managing contacts, performing biometric authentications, and more. Many of these APIs are in various stages of testing or have completed origin trials, particularly on Chrome and Chromium-based browsers, with the aim to standardize and eventually incorporate them into web technologies. This evolution continues to narrow the gap between web and native app functionalities, promising richer user experiences on the web.
