fast-cbor v1.0.0

fast-cbor

Encode and parse data in the Concise Binary Object Representation (CBOR) data format (RFC7049) as fast as possible.

About

This library is a fork of the awesome node-cbor( ). It borrows a lot of the interface, but drops all streaming and async processing in favor of a minimal syn api and being as fast as possible.

Installation

$ npm install --save fast-cbor

Example

const cbor = require('cbor')
const assert = require('assert')

const encoded = cbor.encode(true) // returns <Buffer f5>
const decoded = cbor.decodeFirst(encoded)
// decoded is the unpacked object
assert.ok(obj === true);

// Use integers as keys?
var m = new Map();
m.set(1, 2);
encoded = cbor.encode(m); // <Buffer a1 01 02>

The sync encoding and decoding are exported as a leveldb encoding, as cbor.leveldb.
