RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including cssnano. Try it out:
/*
* This example targets Node 4 and up.
*/
const cssnano = require('cssnano');
/*
* Add your CSS code here.
*/
const css = `
h1 {
color: #ff0000;
font-weight: bold;
}
`;
/*
* Add your configuration here; see http://cssnano.co/options/ and
* http://cssnano.co/optimisations/ for more details.
*
* For example you can turn off z-index rebasing by setting `zindex: false`
* in your config, or you can use `safe: true` which will turn off unsafe
* optimisations.
*/
const opts = {
};
/*
* Compress the CSS asynchronously and log it to the console.
*/
cssnano.process(css, opts).then(result => {
console.log(result.css);
});
