Is there a fix for the Unhandled promise error, in TcpSockets.js . Can someone help me with this?

node_modules\react-native-tcp\TcpSockets.js:16
exports.createServer = function(connectionListener : (socket: Socket) => void) : Server {

I had the same problem. It seems those .js files in this project are written in typescript. I installed a module that lets react-native comprehend typescript automatically and that seems to have sorted it out. https://github.com/ds300/react-native-typescript-transformer

A maintained fork is over at https://github.com/aprock/react-native-tcp (I help to maintain it).

I'd like to help get this sorted out - we use this package as a dependency, and don't use typescript. It seems like this should be a pretty common problem, I'm confused how it doesn't pop up more.
