Source map support during css/js minification

Source map support during css/js minification

Owned by Alex

Source map files allows to see actual code location (in JS/LESS/SCSS files) after they have been compiled/minified. They are usually generated when:

  • JS file is minified (e.g. jQuery)
  • several LESS/SCSS files are compiled into one large CSS file

Unfortunately when In-Portal combines/minifies several JS/CSS files then following happens:

  • the comments (including special ones that have source map file location) are stripped off
  • lines in minified file no longer matches original file before minification

I would love to adjust line numbers in source map file and join all files together, but I don't know how to do it knowing that source map file doesn't have any line numbers in it. Probably it has some sort of line/column hash in there (at least for less source maps).
