Generate Go code from Protocol Buffer files using the protoc command with the --go_out flag.
Use protoc with the --go_out flag and the google.golang.org/protobuf/cmd/protoc-gen-go plugin to generate Go code from .proto files.
protoc --go_out=. --go_opt=paths=source_relative *.proto
This command generates .pb.go files in the same directory as your .proto files, ready to be imported into your Go project.
protoc-gen-go converts your Protocol Buffer definition files into Go code that your application can use. Think of it like a translator that turns a data format blueprint into actual working Go types and functions. You use it whenever you need to send structured data between services or store it efficiently.
