DESCRIPTION

Optimize animate.css stylesheets. Reduce filesize.

The animate.css files (animate.css, animate.min.css) span about 3303 LOCs and come at 70KB and 56KB respectively, because they contain a myriad of usable animated classes.

We can trim down these file sizes, by excluding the classes we don't use.

Example: When performed on a site which used just 7 animate.css classes, the result was a decrease by 88% (Saved: 49.04 kB) on the production version (animate.css) and a reduced size of 87% (Saved: 60.78 kB) on the development / minified version (animate.min.css);

HOW DOES THIS WORKS?

1. The utility scrapes through a list of web pages provided by the user.
2. It then uses cheerio to find the elements that contain the .animated class used by the animate.css library and create a list of the animation classes used on the web site.
3. It then creates a trimmed down version of the animate.css, which contains only the necessary CSS rules for the effects currently used.
4. It also produces a minified version using clean-css.

INSTALLATION / USAGE

• Clone repo

git clone git@github.com:kostasx/animate-css-optim.git

• Install dependencies

cd animate-css-optim
npm install

• Open config.js and replace the sample URLs with the page URLs you want to be scanned for elements containing the .animated class.

• Run the utility:

node optim.js

You will now have an output folder created containing the optimized versions of animate.css and animate.min.css, containing only the classes needed for the elements found to be using them.
