postcss-discard-comments

Discard comments in your CSS files with PostCSS.

Install

With npm do:

npm install postcss-discard-comments --save

Example

Input

h1/* heading */{
    margin: 0 auto
}

Output

h1 {
    margin: 0 auto
}

This module discards comments from your CSS files; by default, it will remove all regular comments (/* comment */) and preserve comments marked as important (/*! important */).

Note that this module does not handle source map comments because they are not available to it; PostCSS handles this internally, so if they are removed then you will have to configure source maps in PostCSS.

API

comments([options])

options

remove(function)

Type: function Return: boolean Variable: comment contains a comment without /**/

For each comment, return true to remove, or false to keep the comment.

function(comment) {}

var css = '/* headings *//*@ h1 */h1{margin:0 auto}/*@ h2 */h2{color:red}';
console.log(postcss(comments({
    remove: function(comment) { return comment[0] == "@"; }
})).process(css).css);
//=> /* headings */h1{margin:0 auto}h2{color:red}

NOTE: If you use the remove function other options will not be available.

removeAll

Type: boolean Default: false

Remove all comments marked as important.

var css = '/*! heading */h1{margin:0 auto}/*! heading 2 */h2{color:red}';
console.log(postcss(comments({removeAll: true})).process(css).css);
//=> h1{margin:0 auto}h2{color:red}

removeAllButFirst

Type: boolean Default: false

Remove all comments marked as important, but the first one.

var css = '/*! heading */h1{margin:0 auto}/*! heading 2 */h2{color:red}';
console.log(postcss(comments({removeAllButFirst: true})).process(css).css);
//=> /*! heading */h1{margin:0 auto}h2{color:red}
