CBOR Kit

A modern, extensible CBOR (Concise Binary Object Representation) library for TypeScript and JavaScript.

By default, CBOR Kit does not support tags and custom objects like JavaScript Maps. However, it can be easily supported by adding custom encoders and decoders. See the Advanced Usage section for more details.

Features

• 🚀 Fast & Lightweight: Optimized encoding and decoding.
• 🔌 Extensible: Easily add custom encoders and decoders.
• 🎯 Customizable: Fine-tune decoding and encoding options.
• ✅ Spec-Compliant: Adheres to RFC 8949.
• 📦 Tree-Shakable: Bundles only the necessary code for your project.
• 💻 TypeScript: Written in TypeScript for type safety and better DX.

Installation

# npm
npm install cborkit

# pnpm
pnpm add cborkit

# yarn
yarn add cborkit

# bun
bun add cborkit

Basic Usage

Encoding

import { encode } from "cborkit/encoder";

const data = { foo: "bar", baz: 123 };
const encoded = encode(data);

console.log(encoded); // [130, 169, 102, 111, 111, 98, 97, 114]

Decoding

import { decode } from "cborkit/decoder";

const encoded = [130, 169, 102, 111, 111, 98, 97, 114];
const decoded = decode(encoded);

console.log(decoded); // { foo: 'bar', baz: 123 }
