observed-remove v2.3.1

Observed-Remove Set and Map

Eventually-consistent, conflict-free replicated data types (CRDT) implemented using native Map and Set objects.

const { ObservedRemoveSet } = require('observed-remove');

const alice = new ObservedRemoveSet();
const bob = new ObservedRemoveSet();

alice.on('publish', (message) => {
  setTimeout(() => bob.process(message), Math.round(Math.random() * 1000));
});

bob.on('publish', (message) => {
  setTimeout(() => alice.process(message), Math.round(Math.random() * 1000));
});

alice.add('foo');
bob.add('bar');

// Later

alice.has('bar'); // true
bob.has('foo'); // true

const { ObservedRemoveMap } = require('observed-remove');

const alice = new ObservedRemoveMap();
const bob = new ObservedRemoveMap();

alice.on('publish', (message) => {
  setTimeout(() => bob.process(message), Math.round(Math.random() * 1000));
});

bob.on('publish', (message) => {
  setTimeout(() => alice.process(message), Math.round(Math.random() * 1000));
});

alice.set('a', 1);
bob.add('b', 2);

// Later

alice.get('b'); // 2
bob.get('a'); // 1
