go-peer

go-libp2p-pubsub chat example

This example project builds a chat room application using go-libp2p. The app runs in the terminal, and uses a text UI to show messages from other peers:

Running

Clone this repo, then cd into the go-peer directory:

git clone https://github.com/libp2p/universal-connectivity
cd universal-connectivity/go-peer

Now you can either run with go run, or build and run the binary:

go run .

# or, build and run separately
go build .
./go-peer

To set a nickname, use the -nick flag:

go run . -nick=zoidberg

You can join a specific chat room with the -room flag:

go run . -room=planet-express

It's usually more fun to chat with others, so open a new terminal and run the app again. If you set a custom chat room name with the -room flag, make sure you use the same one for both apps. Once the new instance starts, the two chat apps should discover each other automatically using mDNS, and typing a message into one app will send it to any others that are open.

To quit, hit Ctrl-C, or type /quit into the input field.
