Remove comments from code

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-stripcomments --save-dev

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


The "comments" task


In your project's Gruntfile, add a section named comments to the data object passed into grunt.initConfig().

  comments: {
    your_target: {
      // Target-specific file lists and/or options go here.
      options: {
          singleline: true,
          multiline: true,
          keepSpecialComments: false
      src: [ 'src/*.js'] // files to remove comments from



Type: Boolean Default value: true

Determines whether or not to remove comments starting with /*!.

Note: NO special comments should be removed if the code is not yours. Special comments are used as attribution and you should consult with the authors before even considering stripping them from the source.


Type: Boolean Default value: true

Determines whether or not to remove single line comments


Type: Boolean Default value: true

Determines whether or not to remove multi line comments

Usage Examples

  comments: {
    js: {
      options: {
        singleline: true,
        multiline: false
      src: [ 'src/*.js' ]
    php: {
      options: {
        singleline: true,
        multiline: true
      src: [ 'lib/*.php' ]


In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
