A library of Conflict-Free Replicated Data Types for JavaScript.
Work In Progress
This module provides a set of Conflict-Free Replicated Data Types for your JavaScript programs. All CRDTs in this library, except G-Counter, are currently operation-based.
CRDTs implemented in this module:
This module uses npm and node.
To install, run:
$ npm install crdtsconst GCounter = require('crdts').GCounter
const PNCounter = require('crdts').PNCounter
const GSet = require('crdts').GSet
const TwoPSet = require('crdts').TwoPSet
const ORSet = require('crdts').ORSet
const LWWSet = require('crdts').LWWSet
// Or:
const { GSet, ORSet, LWWSet } = require('crdts')See the source code for each CRDT for the APIs and tests for usage examples.
