What is Protobuf?

Protocol buffers are Google’s language-neutral, platform-neutral, extensible mechanism for serializing structured data – think XML, but smaller, faster, and simpler.

And what is Pbkit?

Pbkit is a collection of tools related to protobuf.

It is written in TypeScript and uses the Deno api.

However, it can be executed in any JavaScript environment (including Node.js or web browser) because it does not use platform APIs inside the core directory.

What features are provided?


  • pb - Protobuf schema compiler like protoc.
    • protoc has native binary dependencies, but pb command is written in pure TypeScript, so it can be used comfortably in Node.js projects, etc., and can even easily be run in a web browser.
    • How to install and how to use
  • pollapo - A package manager for the protobuf schema.

Browser Extension

Editor Extension
