Create symbolic links.

grunt-contrib-symlink v1.0.0

Create symbolic links.

Getting Started

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-symlink --save-dev

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

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

Symlink task

Run this task with the grunt symlink command.

Task targets, files and options may be specified according to the grunt Configuring tasks guide. Pay special attention to the Building the files object dynamically section, which explains how to create many src-dest file mappings all at once.

Note that the (Windows feature only) symlink mode (file, dir) is determined automatically based on the src file type, but takes into account dirmode parameter and allows using junctions instead of dir symlinks.

Usage Examples

symlink: {
  options: {
    // Enable having dir symlink or junction for Windows
    dirmode: 'dir'
    // Enable overwrite to delete symlinks before recreating them
    overwrite: false,
    // Enable force to overwrite symlinks outside the current working directory
    force: false
  },
  // The "build/target.txt" symlink will be created and linked to
  // "source/target.txt". It should appear like this in a file listing:
  // build/target.txt -> ../source/target.txt
  explicit: {
    src: 'source/target.txt',
    dest: 'build/target.txt'
  },
  // These examples using "expand" to generate src-dest file mappings:
  // http://gruntjs.com/configuring-tasks#building-the-files-object-dynamically
  expanded: {
    files: [
      // All child files and directories in "source", starting with "foo-" will
      // be symlinked into the "build" directory, with the leading "source"
      // stripped off.
      {
        expand: true,
        overwrite: false,
        cwd: 'source',
        src: ['foo-*'],
        dest: 'build'
      },
      // All child directories in "source" will be symlinked (or junctioned on Windows only) into the "build"
      // directory, with the leading "source" stripped off.
      {
        expand: true,
        overwrite: false,
        dirmode: 'junction',
        cwd: 'source',
        src: ['*'],
        dest: 'build',
        filter: 'isDirectory'
      }
    ]
  },
}

CLI overwrite option

To override the overwrite option via the CLI pass it as an option

  grunt symlink --overwrite

Usage tips on Microsoft Windows

Make sure your command prompt has administrative privileges for standard symlinks, otherwise the task will not work. Junctions does not require administrative privileges but due to bug in old version of node (v0.10) they are required.
