Graph.js – a Graph Algorithms Library in JavaScript

Hello World!
I am writing a blog post after long time. I was quite a busy these days. One day I thought of developing a game in JavaScript. The game design was such that it required graph algorithms implementation in JS. I googled but found nothing suitable for my work. So I though of implementing my own Graph Algorithms Library in JavaScript.This post is in regard to Graph.js ( Github Repo ) – a lite weight JavaScript Graph Algorithms Library. Graph.js is easy to use , change and debug. All the algorithms present in it are efficient in terms of space and time complexity.

Algorithms implemented

• Depth First Search
• Breadth First Search
• Dijkstra – Shortest Distance between two nodes
• Bellman Ford – Shortest Distance between two nodes.
• Johnson’s Algorithm for all pair shortest path.
• Prim’s Algorithm for minimum spanning tree of Undirected complete graph.

How to use

Just include graph.js file in your application .
If you want to build the file from the source code you can just run the make command from the top level directory of the project.

Future Additions to the project

• Implement more algorithms like clustering , max flow , bipartite matching , random graph generation.
• Add some test suite ( Preferably QUnit )
• Add a graph visualizer ( Big Enhancement)
• Some very good code examples of the usage of library.

Note : You can visit Github Repo for example code and other information. As the library is in nascent stage you can find errors . Feel free to fork , make pull requests and report errors.
