postcss-discard-comments
Advanced tools
Discard comments in your CSS files with PostCSS.
With npm do:
npm install postcss-discard-comments --save
h1/* heading */{
margin: 0 auto
}
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.
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.
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}
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}
