Proto — @coderbuzz/proto

Binary serialization for TypeScript. Smaller than Protobuf. No .proto files. Zero per-field overhead.

Compiles high-performance binary codecs from @coderbuzz/veta schema validators at runtime. No field names, no type tags, no per-field headers — just pure payload data.

Why Proto Over Standard Protobuf?

• No .proto files — schemas are TypeScript validators from @coderbuzz/veta
• Zero per-field overhead — Protobuf adds tag + wire type per field; Proto adds nothing
• Smaller than MessagePack — no type tags on every value
• size() pre-calculation — exact byte count without encoding
• Literals are 0 bytes — value known from schema
• Unions in 1 byte — variant index prefix instead of Protobuf's oneof wrapper

Installation

npm install @coderbuzz/proto @coderbuzz/veta

Quick Start

import { proto } from "@coderbuzz/proto";
import { object, string, number } from "@coderbuzz/veta";

const User = object({ name: string(), age: number() });
const codec = proto(User);

const bytes = codec.encode({ name: "Alice", age: 30 });
// Binary — no field names, no tags, just payload

const user = codec.decode(bytes);
// => { name: "Alice", age: 30 }
