Package Exports

graph-data-structure

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (graph-data-structure) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

graph-data-structure

A graph data structure with topological sort algorithm.

Usage

Install the library by running

npm install graph-data-structure

Require it in your code like this.

var Graph = require("graph-data-structure");

Create a graph.

var graph = Graph();

Add some nodes and edges.

graph.addNode("a");
graph.addNode("b");
graph.addEdge("a", "b");

Nodes are added implicitly when edges are added.

graph.addEdge("b", "c");

Topological sort can be invoked with an array source nodes (which are excluded from the result).

graph.topologicalSort(["a"]); // Returns ["b", "c"]
