Give it a go:

git clone https://gist.github.com/6200029.git make-asset-compilation
cd make-asset-compilation
npm install
node_modules/.bin/bower install
mkdir -p javascripts sass public
echo 'console.log("Hello world");' > javascripts/myapp.js
echo 'html { background: papayawhip; }' > sass/myapp.scss
make

And then look in public to see your compiled files.

To watch it auto-recompile on file change, run make watch and then edit javascripts/myapp.js or sass/myapp.scss

bower.json

{
  "name": "myapp",
  "dependencies": {
    "angular": "x"
  }
}

Makefile

# A simple Makefile alternative to using Grunt for your static asset compilation
#
## Usage
#
#   $ npm install
#
# And then you can run various commands:
#
#   $ make            # compile files that need compiling
#   $ make clean all  # remove target files and recompile from scratch
#   $ make watch      # watch the filesystem for changes and recompile
#
## Why?
#
# 1. Less dependencies
#
# Instead of needing a grunt-* wrapper library for your favourite tool, and
# needing to update or wait for a new version just to pass a new option into
# the underlying library, you can simply use the library directly.
#
# Thankfully all the awesome node libraries you're using with Grunt include
# command-line tools which are easily executable by make.
#
# 2. Easy to extend
#
# For this example we're using some linux commands for concating, and various
# node-based libraries for Sass compilation, CSS prefixing, etc.
#
# Adding a new tool or step to your asset compilation is dead simple:
#
#   1. add the library to package.json
#   2. npm install
#   3. add a new line to the revelant target, calling the binary created by npm
#      install
#
# 3. Performance
#
# Makefile understands file modification times, so it won't recompile any
# targets whose source dependencies haven't changed. Combined with using a
# file modification monitoring tool like wach, you get near-instant recompiles
# of your front-end assets.

# Targets
#
# The format goes:
#
#   target: list of dependencies
#     commands to build target
#
# If something isn't re-compiling double-check the changed file is in the
# target's dependencies list.

# Phony targets - these are for when the target-side of a definition
# (such as "all" below) isn't a file but instead a just label. Declaring
# it as phony ensures that it always run, even if a file by the same name
# exists.
