See main.go for usage example. The code is runnable with just go run main.go
Add these lines to your go.mod file:
require Network-go v0.0.0
replace Network-go => ./Network-go
Where ./Network-go is the relative path to this folder, after you have downloaded it.
Channel-in/channel-out pairs of (almost) any custom or built-in data type can be supplied to a pair of transmitter/receiver functions. Data sent to the transmitter function is automatically serialized and broadcast on the specified port. Any messages received on the receiver's port are de-serialized (as long as they match any of the receiver's supplied channel data types) and sent on the corresponding channel. See bcast.Transmitter and bcast.Receiver.
Peers on the local network can be detected by supplying your own ID to a transmitter and receiving peer updates (new, current, and lost peers) from the receiver. See peers.Transmitter and peers.Receiver.
Finding your own local IP address can be done with the LocalIP convenience function, but only when you are connected to the internet.
