Copy 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-copy --save-dev

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

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

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 copy command.

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

Type: Function(content, srcpath)

This option is passed to grunt.file.copy as an advanced way to control the file contents that are copied.

Type: String

This option is passed to grunt.file.copy as an advanced way to control which file contents are processed.

copy: {
  main: {
    files: [
      {expand: true, src: ['path/*'], dest: 'dest/', filter: 'isFile'}, // includes files in path
      {expand: true, src: ['path/**'], dest: 'dest/'}, // includes files in path and its subdirs
      {expand: true, cwd: 'path/', src: ['**'], dest: 'dest/'}, // makes all src relative to cwd
      {expand: true, flatten: true, src: ['path/**'], dest: 'dest/', filter: 'isFile'} // flattens results to a single level
    ]
  }
}

This task supports all the file mapping format Grunt supports. Please read Globbing patterns and Building the files object dynamically for additional details.

Here are some examples, given the following file tree:

$ tree -I node_modules
.
├── Gruntfile.js
└── src
    ├── a
    └── subdir
        └── b

2 directories, 3 files

Copy a single file tree:

copy: {
  main: {
    src: 'src/*',
    dest: 'dest/',
  },
},

$ grunt copy
Running "copy:main" (copy) task
Created 1 directories, copied 1 files

Done, without errors.
$ tree -I node_modules
.
├── Gruntfile.js
├── dest
│   └── src
│       ├── a
│       └── subdir
└── src
    ├── a
    └── subdir
        └── b

5 directories, 4 files

Flattening the filepath output:

copy: {
  main: {
    expand: true,
    cwd: 'src/',
    src: '**',
    dest: 'dest/',
    flatten: true,
    filter: 'isFile',
  },
},

$ grunt copy
Running "copy:main" (copy) task
Copied 2 files

Done, without errors.
$ tree -I node_modules
.
├── Gruntfile.js
├── dest
│   ├── a
│   └── b
└── src
    ├── a
    └── subdir
        └── b

3 directories, 5 files
