js-in-css-runtime

Redistributable runtime for running JS-in-CSS in your own website

How to use

Link the runtime to your page like this

import { runtime } from 'js-in-css-rt';
 
/* after your dom has loaded */
runtime.init();

This won't do much at first because you need some JS-in-CSS to get it going. In your stylesheet, add a --eval variable containing the JS you want to run. this will be mapped to the Element that matches the selector. For example this will make your footer both stylish and always be up to date with the current year:

footer {
    border: 3px solid red;
    color: white;
    background: blue;
    --eval: 'this.innerText = `©${(new Date).getFullYear()} My Web Site`';
}

FAQs

Does this work with CSS processors such as SASS/Less/PostCSS

Yes! The runtime targets compiled CSS at the last stage. Just make sure your compiler understands CSS variables and doesn't strip them out.

Can I use this with native browser modules

Yes! try import { runtime } from 'node_modules/js-in-css-rt/index.js'. You might want to invest in some tooling to not expose your entire node_modules folder.

I'm unsure if this is an elaborate trolling attempt or a legitimate library

Follow your heart and you will never go wrong

Wait what

Does this work with CSS-in-JS solutions such as Emotion

There's no reason it shouldn'd. Please let me know if you set that up it's been a somber month for me personally and I need a chuckle

There's a typo in the previous answer

Happy little accidents
