Compress files and folders.
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-devOnce 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.
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).
Type: String or Function
Modes: zip tar
This is used to define where to output the archive. Each target can only have one output file. If the type is a Function it must return a String.
This option is only appropriate for many-files-to-one compression modes like zip and tar. For gzip for example, please use grunt's standard src/dest specifications.
Type: String
This is used to define which mode to use, currently supports gzip, deflate, deflateRaw, tar, tgz (tar gzip) and zip.
Automatically detected per dest:src pair, but can be overridden per target if desired.
Type: Integer
Modes: zip gzip
Default: 1
Sets the level of archive compression.
Type: Boolean
Default: false
Pretty print file sizes when logging.
The following additonal keys may be passed as part of a dest:src pair when using an Archiver-backed format.
All keys can be defined as a Function that receives the file name and returns in the type specified below.
Type: Date
Modes: zip tar tgz
Sets the file date.
Type: Integer
Modes: zip tar tgz
Sets the file permissions.
Type: Boolean
Modes: zip
If true, file contents will be archived without compression.
Type: String
Modes: zip
Sets the file comment.
// 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/'
}
}// use custom extension for the output file
compress: {
main: {
options: {
mode: 'gzip'
},
files: [
// Each of the files in the src/ folder will be output to
// the dist/ folder each with the extension .gz.js
{expand: true, src: ['src/*.js'], dest: 'dist/', ext: '.gz.js'}
]
}
}// use a function to return the output file
compress: {
main: {
options: {
archive: function () {
// The global value git.tag is set by another task
return git.tag + '.zip'
}
},
files: [
{expand: true, src: ['src/*.js'], dest: 'dist/'}
]
}
