cssnano VS stylus

Use free tools like Terser for JavaScript and CSSNano for CSS:

Minify CSS: Strip out comments, whitespace, and redundant code with tools like CSSNano or CleanCSS. A 100KB stylesheet might shrink to 70KB, speeding up downloads.

cssnano has had some complicated ownership turnover[0], I'm glad to see someone took the mantle again though.

I do find that CSSO[1] with structural optimizations can be more effective still, perhaps that will be less true overtime though.

I think once lightning CSS is more stable (in particular, some bugs are addressed around ordering) it will be the clear winner in this space though.

cssnano/cssnano - A modular minifier, built on top of the PostCSS ecosystem.

There are a number of tools available to minify CSS in development or as part of your build pipeline including, but not limited to, cssnano and Vite. If you’re using sass, it’s as straightforward as adding --style=compressed to your sass command. The results you achieve may vary depending on the complexity of your CSS, but you may see numbers similar to this (processed with sass):

Since Tailwind is a PostCSS plugin, we can also add cssnano plugin to compress the bundle.

Minifying your CSS involves removing unnecessary whitespace, comments, and reducing property names. This results in smaller file sizes and faster downloads. Use tools like UglifyCSS and CSSNano for this purpose.

For the sake of simplicity, my example setup uses a single-file plugin and puts all styles directly into a single style.css file without using further theme.css or theme.json files, which we might want to use depending on the requirements for customizability. Likewise, SASS / SCSS support can be added if it makes life easier for the developer(s) involved. But as we already use PostCSS to control autoprefixing and cssnano minification, we can also use it to support the latest and even upcoming CSS sytax like native CSS nesting.

The cssnano plugin can minify/compress CSS and make it suitable for production use. Install cssnano plugin using this command:

Supports Less/Sass/Stylus.

Stylus: Provides a more efficient and elegant way to generate CSS.

Sass, Less and Stylus, extends CSS by adding variables, nesting mixins, and other features. It's an excellent solution for organizing huge and complex stylesheets.

I hate preprocessors. Be it SASS, SCSS, LESS, Stylus, or any other. Really, without any exceptions. Though, I think my hatred for preprocessors is not because of the technology itself, but because of how other people use them. Throughout my development career, I have often encountered tickets where a seemingly simple task, like changing the text size, which should take minutes, ended up taking me hours. This is because people often want to use the tool to its full extent. As a result, to find where I needed to change the text size in projects using preprocessors to the max, I had to go through several mixins, maybe a loop or even nested loops, and several nested selectors using the parent selector. Brr, just thinking about it gives me the shivers.

Traditionally CSS lacked features such as variables, nesting, mixins, and functions. This was frustrating for Developers as it often led to CSS quickly becoming complex and cumbersome. In an attempt to make code easier and less repetitive CSS pre-processors were born. You would write CSS in the format the pre-processor understood and, at build time, you'd have some nice CSS. The most common pre-processors these days are Sass, Less, and Stylus. Any examples I give going forward will be about Sass as that's what I'm most familiar with.

Stylus

The Stylus is built on Node.js. It differs from Sass and Less, which are more opinionated to the syntax; the stylus allows you to omit semicolons, colons, and braces if you want at any time. Another cool feature is that the stylus has a property lookup feature. You can do that easily if you set property X relative to property Y's value. The stylus can be more concise because of its flexibility, but it depends on your preferred syntax.
