Proof of Concept project

Hey there,

I was looking through the examples and I want to set up a proof of concept project that connects some libp2p packages in a real environment.

Therefore I am planning to set up a simple project in js like a chat, but different to the chat example given, I would like to connect two real nodes behind NATs (and maybe spice the example up by using peer routing in the chat or so)

Is there any existing project, that is open to use, because I feel its kind of difficult to put all this parts of libp2p to work and to get it going in a real environment.

Edit: I would like to extend the chat example by connection the peers via web-rtc-star as in here

Thanks in advance and best regards,
