RTCPeerConnection Shim for ORTC

The rtcpeerconnection-shim package (v1.2.15) is a JavaScript library that provides a polyfill/shim implementing the W3C RTCPeerConnection API on top of the ORTC (Object RTC) API, which is used by Microsoft Edge (pre-Chromium). It allows developers to use the standard WebRTC RTCPeerConnection interface in environments that only support ORTC. The project is in maintenance mode, with its last release in 2018. It offers a compatibility layer, but it is limited compared to native WebRTC support. Key differentiator: it enables RTCPeerConnection in legacy Edge; however, it is no longer needed in modern browsers and has subtle API differences.
