A year ago I created a sample project to get people started locally with react-native-webrtc without having to troubleshoot for hours. Since then it’s received nearly 100 stars, and had nearly 2k clicks from my post here to see it. For open-source thanksgiving I’ve gone through and upgraded to RN 0.63.3 and RNW 1.87.5 for both android and iOS.

Hope it keeps helping someone
