As is go build ./examples/protocol-multiplexing-with-multicodecs will make the binary name protocol-multiplexing-with-multicodecs so the next command ./multicodecs won't run using -o will name the outputfile
Protocol Multiplexing using multicodecs with libp2p
This examples shows how to use multicodecs (i.e. json) to encode and transmit information between LibP2P hosts using LibP2P Streams.
Multicodecs present a common interface, making it very easy to swap the codec implementation if needed.
This example expects that you area already familiar with the echo example.
Build
From go-libp2p base folder:
> make deps-protocol-muxing
> go build -o multicodecs ./examples/protocol-multiplexing-with-multicodecs
Usage
> ./multicodecs
Details
The example creates two LibP2P Hosts. Host1 opens a stream to Host2. Host2 has an StreamHandler to deal with the incoming stream. This is covered in the echo example.
Both hosts simulate a conversation. But rather than sending raw messages on the stream, each message in the conversation is encoded under a json object (using the json multicodec). For example:
{
"Msg": "This is the message",
"Index": 3,
"HangUp": false
}
The stream lasts until one of the sides closes it when the HangUp field is true.
