Generate Go code from Protobuf definitions using the protoc compiler and the protoc-gen-go plugin.
Use the go tool to generate Go code from .proto files by running protoc with the Go plugin. First, install the plugin, then run the compiler with the --go_out flag pointing to your output directory.
go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
protoc --go_out=. --go_opt=paths=source_relative *.proto
This generates .pb.go files containing the proto definitions ready for import in your Go project.
Protobuf is a way to define data structures in a simple file format that works across different programming languages. When you use it with Go, a tool translates your definition file into Go code so your application can easily send and receive that data. Think of it like a translator that turns a universal blueprint into specific instructions your Go program can follow.
