cruft

Package cruft removal.

Build Status

cruft tries to remove files from codebases that are not required in production such as documentation, tests and examples. This is potentially very dangerous, use with a high level of caution.

The primary usecase is for deploying to devices with constrained diskspace (e.g. NinjaBlocks) or bandwidth (e.g. Australia).

Usage

> cruft clear --help
  Usage: cruft-clear [options]

  Options:

    -h, --help         output usage information
    -V, --version      output the version number
    -f, --file [file]  markdown file containing cruft definitions
    -v, --verbose      verbose output

Example Usage

> npm install -g cruft
> cd my-crufty-app
> cruft clear
  cruft before +0ms 82.11mb
  cruft after +15ms 31.46mb
  cruft 50.65mb of cruft cleared! +3ms
  cruft 61.68% reduction! +10ms

You'll be surprised how much cruft there is in your codebase. Try it and see!

Specifying Cruft

cruft uses dominictarr/rc for its configuration, so you can specify cruft in various ways, including a config.json file specified by --config. See dominictarr/rc for other ways to specify configuration. cruft's app-name is 'cruft'.

> cat config.json # __defaults apply to every module
"cruft": {
  "__defaults": ["test", "examples"],
  "some-module": ["images"]
}
> cruft clear --config config.json

By default, this will add to the default cruft listed below. To turn off the default cruft, use --noDefaultCruft:

# use cruft_cruft environment variable to specify a custom cruft pattern
# and --noDefaultCruft to disable default cruft patterns
> cruft_cruft="tests" cruft clear --noDefaultCruft

Identifying Cruft

cruft uses visionmedia/mdconf to get a list of default patterns to match straight from this readme. If you find a package that has additional cruft, or mistakenly identified cruft, submit a pull request to update the list in this readme.

Default Cruft

By default, the following content will be removed.

  • example
  • examples
  • test
  • tests
  • doc
  • man

Cruft Found

This is a list of npm packages and their cruft. If a package is found in this list when cruft is run, any listed content will be removed.

Entries starting with a bang will not be removed. e.g. override defaults in the case they remove something they should not.
