Recording audio and streaming to clients from nodejs

I need to take recorded audio (I believe using the getUserMedia() function) and stream it to connected clients' browser from a nodejs server. I've looked around at some examples with nothing too definitive, and with varying approaches.

I can't use webrtc. It must be using a server to send a stream to clients. I can however use getUserMedia() (which I believe is part of webrtc) to record the audio and send it to the nodejs server).

Are there any resources or examples that show something like this working?
