Spackle

A tiny command-line utility to pack JS bundles for the web

Basically just a wrapper around browserify and minifyify.
It takes a bunch of input JS and spits out a browserified version.
The source map is inline by default.
If you give it the name of a source map file, it will create that instead, and minify the source.

First pick your favorite way to install, e.g.:

git clone https://github.com/jflatow/spackle.git
cd spackle
npm link

Then spackle it up:

spackle all.js my.js files.js > bundle.js
spackle site.js -s bundle.map.js > bundle.js

Requirements get pulled in automatically thanks to browserify.
Dead code is removed thanks to minifyify.

Also a simple tool to inline CSS

In this case, just a wrapper around inline-css.
As easy as:

spackle -i stylish.html > inline.html
