Protocol Buffers (Protobuf) is a method of serializing structured data,

- useful for storing it on disk or sending over the wire.

Benefits of ProtoBuf

Schema

Binary compact size

Language neutral

Cons

Have to have structured data (barrier to entry)

More involved processed for small applications.

Have to make sure to update compiled boilerplate code (bugs, security vulnerability, etc.)

hard to use with JSON based application (Javascript/browser)

To run (using npm):

use either:

npm start

or

node demoJson

• will create a JSON file

To test protocol buffer implementation:

npm install google-protobuf

ProtoC compiler download [select the latest compiler for your operating system]

• https://github.com/protocolbuffers/pr...

Optional:

vscode-proto3 (Protobuf 3 support if your running in Visual Studio Code)

Pre-fix following terminal command with location of your protoc download:

/protoc-3.19.1-osx-x86_64/bin/protoc --js_out=import_style=commonjs,binary:. employees.proto

To run protocol buffer implementation:

node demoProtobuf

• will create a binary file

run ls -lh in your directory - compare file sizes
