grunt-contrib-compress

grunt-contrib-compress

Compress files and folders.

Getting Started

This plugin requires Grunt ~0.4.0

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-contrib-compress --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-contrib-compress');

This plugin was designed to work with Grunt 0.4.x. If you're still using grunt v0.3.x it's strongly recommended that you upgrade, but in case you can't please use v0.3.2.

Compress task

Run this task with the grunt compress command.

Task targets, files and options may be specified according to the grunt Configuring tasks guide.

Node Libraries Used: archiver (for zip/tar) zlib (for gzip).

Options

archive

Type: String

This is used to define where to output the archive. Each target can only have one output file.

mode

Type: String

This is used to define which mode to use, currently supports gzip, tar, tgz (tar gzip) and zip.

Automatically detected per dest:src pair, but can be overridden per target if desired.

level (zip only)

Type: Integer Default: 1

Sets the level of archive compression.

Currently, gzip compression related options are not supported due to deficiencies in node's zlib library.

pretty

Type: Boolean Default: false

Pretty print file sizes when logging.

Usage Examples

// make a zipfile
compress: {
  main: {
    options: {
      archive: 'archive.zip'
    },
    files: [
      {src: ['path/*'], dest: 'internal_folder/', filter: 'isFile'}, // includes files in path
      {src: ['path/**'], dest: 'internal_folder2/'}, // includes files in path and its subdirs
      {expand: true, cwd: 'path/', src: ['**'], dest: 'internal_folder3/'}, // makes all src relative to cwd
      {flatten: true, src: ['path/**'], dest: 'internal_folder4/', filter: 'isFile'} // flattens results to a single level
    ]
  }
}

// gzip assets 1-to-1 for production
compress: {
  main: {
    options: {
      mode: 'gzip'
    },
    expand: true,
    cwd: 'assets/',
    src: ['**/*'],
    dest: 'public/'
  }
}
