2. Setup

$ make proto
$ make build

3. Usage

$ ./cmd/main

• ping.json: json serialized structure

{"Nonce":48879, "Timeout":"2", "BeaconID":"uuid-bot"}

• ping.wire: wire serialized structure

$ xxd -g4 ./ping.wire
00000000: 08effd02 10021a08 75756964 2d626f74  ........uuid-bot

• ping.wire.lte: wire serialized structure little endian

$ xxd -g4 ./ping.wire.lte
00000000: efbeadde 1337cafe 08effd02 10021a08  .....7..........
00000010: 75756964 2d626f74                    uuid-bot

Perceived benefits of using protobuf

• single source of truth for domain entities throughout the codebase
• provide serializaton/deserializaton for moving data between and client & server or between micro-services.
• transport channel agnostic;
  • serialize payloads could be moved over GRPC
  • http
  • tcp sockets
  • higher customized protocols depending on you.
