evented-graph

Evented-graph is a Graph, inherited from EventEmitter, which is more useful in some practical cases, comparing to the pure graph. Evented-graph emits mutator events: add, delete, clear, connect, disconnect. It also emits change for every actual mutation.

Usage

var Graph = require('evented-graph');
 
var graph = new Graph();
 
graph.on('add', function (node) {
    console.log('Add a new node ', node);
});
 
graph.add(1);
