Is there a tool available that can compress, minify, and combine CSS files while generating a valid v3 SourceMap compatible with Chrome? Ideally, I am looking for a NodeJS tool.
From my research, some Node compressors like clean-css, csso, css-condense (which uses css-parse but struggles with bootstrap.css), and cssmin (a YUI port without a CLI) do not seem to offer source-map support.
I have heard that SASS (Ruby) and Less.js may be developing implementations, but these are preprocessor tools.
Mincer has just released version 1.0.0 with added support for source maps, making it the Ruby Sprockets equivalent for Node.js. Stay up to date with the latest engine developments on the project's wiki.
For CSS processing, you can currently use the LESS + AutoPrefixer + CssWring combination. Although SASS also supports source maps, it has not been integrated into Mincer yet.
It is expected that Stylus will soon include source maps support as well.
For effective minification and bundling of JavaScript and CSS files, I highly recommend utilizing the capabilities of . This tool seamlessly integrates with Bootstrap and offers a user-friendly experience.
With features such as sourcemaps handling and file bundling, you can easily customize your minification process according to your specific requirements. Various options are available, but I personally utilize XML files to specify which files need to be minified and bundled. Alternatively, you can use the command line for a more streamlined approach.
It's worth noting that while I found this tool ideal for compile time creation, it may not be suitable for scenarios requiring runtime creation. In such cases, it's advisable to explore other options.
