CRDTs

A CRDT library for JavaScript.

WIP

This module provides a set of Conflict-Free Replicated Data Types for your JavaScript programs. All CRDTs in this library are currently operation-based.

Implemented CRDTs:

• G-Counter
• G-Set
• 2P-Set
• OR-Set
• LWW-Set

Usage

npm install crdts

const GCounter = require('crdts/src/G-Counter')
const GSet = require('crdts/src/G-Set')
const TwoPSet = require('crdts/src/2P-Set')
const ORSet = require('crdts/src/OR-Set')
const LWWSet = require('crdts/src/LWW-Set')

See the source code for each CRDT for the APIs and tests for usage examples.
