Visualize your CommonJS, AMD, or ES6 module dependencies in a force directed graph report - powered by D3.js.

NEW MAINTAINER WANTED: This project hasn't been maintained in while, so if you wanna help out, please let me know!


Let me introduce dependo - A small visualization tool that draws an force directed graph of JavaScript dependencies pulled from a codebase of CommonJS, AMD, or ES6. Behind the scene I’m using a wonderful library named node-madge, to extract the dependencies and combined with the power of D3.js I draw a beautiful zoomable directed graph.

You can read the full introduction to the project in my blog post.


  • Draw a graph of nodes, where each module is represented as a node.
  • Google Maps's like zooming, dragging and panning.
  • Connect nodes with it's dependencies via lines.
  • Hovering a node will highlight it's direct dependencies.
  • It's possible to drag a node to a specific position, to re-layout the graph.

Report example

The best way to show something is by example, so here I generated a graph of the official RequireJS multipage example:


See the example here:


To install as a library:

$ npm install dependo

To install the command-line tool:

$ sudo npm -g install dependo


    'format': The module format to expect, 'cjs', 'amd', 'es6', or 'json'. AMD (amd) is the default format. If 'json', pass a file formatted like `example.json` in the `example/` directory.
    'optimized': Boolean, True if the parser should read modules from a optimized file (r.js). Defaults to false.
    'exclude': String from which a regex will be constructed for excluding files from the scan.
    'mainRequireModule': Name of the module if parsing an optimized file (r.js), where the main file used require() instead of define. Defaults to ''.
    'requireConfig': Path to RequireJS config used to find shim dependencies and path aliases. Not used by default.
    'reverse': Reverse dependency arrow directions.
    'title': The title of the generated HTML document.
    'extensions': Valid file extensions used to find files in directories e.g. .js,.ts Default: .js


  var Dependo = require('dependo');

// Fire up an dependo instance var dependo = new Dependo(src, { format: 'amd', requireConfig: 'optional path to RequireJS config file', exclude: '^node_modules', transform: function(dep){ //Apply a transformation on dependencies ....

    return dep;



dependo.generateHtml(); ...


Usage: dependo [options] 


-h, --help output usage information -V, --version output the version number -f, --format format to parse (amd/cjs/es6/json) -x, --exclude a regular expression for excluding modules -t, --title the title of the generated document (dependo) -v, --reverse reverse direction of arrows -e, --extensions file extensions to use separated by comma</p>

Generate HTML report of all module dependencies (AMD), and save it to /example/report.html

$ dependo -f amd /path/src > example/report.html


I also wrote a grunt-task that can be found in this separate repository:


dependo is still very much in progress, so here is the todo-list:

  • Proper label positioning: Avoid label collisions and make the graph more readable.
  • Testing! Unit tests of D3 render logic, and the grunt-task itself

Thanks to

This project wouldn't have been possible without the great work on node-madge by Patrik Henningson, or wonderful D3.js library.
