If you know what is JSON and how its work, you can see how much Proto-Buf is easy.
What you dont know you think its hard but when you start to test and working on, you will see its easy.
- First example implenment using JSON at
json.jsfile, - And next same example implenment using Protobuf inside
protobuf.jsfile.
$ protoc --js_out=import_style=commonjs,binary:. employees.proto[max@workstation grpc-series-protobuf-js]$ ls -al
| Size | Filename | Method |
|---|---|---|
| 123 | employees.json | JSON |
| 48 | employees.bin | Protobuf |
[max@workstation grpc-series-protobuf-js]$ node protobuf.js

You need to install protoc program on your system, you can download it from https://github.com/protocolbuffers/protobuf/releases depends on your Operation system. whatever your system is Liunx, Windows or OSX.
Next you can run bin/protoc by typing its full path.
For example:
$ /to-the-path/bin/protoc --js_out=import_style=commonjs,binary:. /your-source-path/employees.protoIf you want to install/setup it globally you have to put bin and include directory to your system directory.
You need to copy these directory to the system dir:
bin->/usr/bin/include->/usr/include/
Maybe, A command to help you:
$ cp -a * /usr/If you want to learn protobuf funcitonally deeply, you can check and read the generated file by Protoc at employees_pb.js. c
