Duo is a next-generation package manager that blends the best ideas from Component, Browserify and Go to make organizing and writing front-end code quick and painless.

Features

  1. has first-class support for Javascript, HTML and CSS
  2. exposes a unix-y command line interface
  3. pulls source directly from GitHub with semantic versioning
  4. supports source transforms, like Coffeescript or Sass
  5. does not require a manifest

Installation

Install Duo straight from

npm
with:
$ npm install -g duo

Getting Started

To get started just write normal Javascript, requiring dependencies straight from the file system or from GitHub as you need them:

var uid = require('matthewmueller/uid');
var fmt = require('yields/fmt');

var msg = fmt('Your unique ID is %s!', uid()); window.alert(msg);

Then use

duo
to install your dependencies and build your file:
$ duo index.js

Finally, drop a single

 onto your page and you're done!

Same goes for CSS! You can require dependencies and assets from the file system or straight from GitHub:

@import 'necolas/normalize.css';

body { color: teal; background: url('./background-image.jpg'); }

Then bundle up your CSS with

duo
:
$ duo index.css

And add your bundled-up stylesheet to your page!

here: https://github.com/settings/tokens/new

Debugging

DEBUG=duo*
to your
$COMMAND
:
$ DEBUG=duo* $COMMAND

Example:

$ DEBUG=duo* duo index.js

If you can't figure it out, you should open an issue: https://github.com/duojs/duo/issues
