Hey guys.

Do you guys have an implementation in place for running postcss in the browser? Is there anything that prevents you guys from making it work in JavaScript on a browser without node? I did some work setting up rollup UMD bundles and it works somewhat, but it would be great if the NPM package included a bundled file that can be used directly in the browser.

If you want to process CSS in string in browser, just use browserify or webpack to pack npm modules of postcss and PostCSS plugins to bundle.

PostCSS don’t need node.js API to process CSS string (it loads fs module, but webpack/browserify have a nice hack for it).

But you need to make bundle by your own. There are 2 reasons:

1. npm community should really think about npm packages sizes. Having a pack in npm package will increase package size to 3-4 times.
2. Anyway you need bundles not only for PostCSS core itself, but also for plugins. So anyway you will use browserify/webpack to packe PostCSS core with PostCSS plugins.
