cssnano VS HTMLMinifier

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:

cssnano is used to ensure that the final result is as small as possible for a production environment.

There are plenty of free plugins are available to optimize styles, scripts and create source maps for them. Optimize styles Optimize Scripts Create Sourcemaps

This project uses HTMLMinifier, optipng, and zopfli to create a custom production Elm build pipeline. You can see how I make use of these tools in this build script. Here are the results in case you're interested. I used the same ideas from this project to build and deploy dwayne/elm-conduit, which you can learn more about in my article Yet Another Tour of an Open-Source Elm SPA.

Minification involves removing unnecessary characters, whitespace, and comments from code files. It helps reduce HTML, CSS, JavaScript, etc., file sizes without compromising functionality. Removing redundant elements makes these HTML, JavaScript, and CSS files smaller. Since smaller code files need less internet traffic to transfer, they load faster. Utilizing tools like UglifyJS, Clean-CSS, and HTMLMinifier enhances this process of code reduction. They analyze the code, remove redundant code, and generate optimized files for deployment.

html-minifier works since it has a cli and I can do something like the authors states in the documentation html-minifier --collapse-whitespace inside package.json "scripts": { }, thus I can run the task through the VSCode interface

HTMLMinifier

I found this one https://github.com/kangax/html-minifier which seems to be browser compatible, but impossible to get it to build with my setup (Next.js + typescript).

That's Minifcation and you'd normally thigs like https://github.com/kangax/html-minifier

I am not sure what you'd use this tool for possibly for scraping work but beautiful soup is probably better for that
