Extracting and referencing multiple CSS files in ejected create-react-app












1















I have an ejected create-react-app (webpack version 3.8.1) that will be implemented as a third-party widget on other websites.
The components are rendered in multiple iframes using react-frame-component.



When styling the components inside iframes I include the css in the head of the iframe.
Right now I'm doing it by loading the css into a string like this:



// IframeComponentOne.js
const innerStyles = require("./iframe-component-one-styles.scss").toString();

render() {
return (
<Frame
head={<style>{innerStyles}</style>}
>
<CompA />
<CompB />
...
</Frame>
)
}

// IframeComponentTwo.js
const innerStyles = require("./iframe-component-two-styles.scss").toString();

render () {
return (
<Frame
head={<style>{innerStyles}</style>}
>
<CompC />
<CompD />
...
</Frame>
)
}


However, to minimize bundle size, and defer css loading, I would like to extract the css into separate files and link to them in the iframes like this:



render() {
return (
<Frame
head={<link rel="stylesheet" href="specific-frame.[hash].css">}
>
<CompX />
<CompY />
...
)
</Frame>


I'm aware that I probably need to use extract-text-webpack-plugin to extract the different innerStyles, but can't the webpack setup right.



How would a webpack setup for this look?
How do I reference the extraced css bundles with content hashes in the head of the iframe components?

          If you upgrade to Webpack 4, you can do this without much additional configuration with mini-css-extract-plugin.



          With webpack 3, you will need this configuration in your webpack config file



          const ExtractTextPlugin = require('extract-text-webpack-plugin');

          module.exports = {
          module: {
          rules: [
          {
          test: /.scss$/,
          use: ExtractTextPlugin.extract({
          fallback: 'style-loader',
          use: ['css-loader', 'sass-loader']
          })
          }
          ]
          },
          plugins: [
          new ExtractTextPlugin('style.css')
          ]
          }


          We cannot say much without looking at your webpack config. but more or less, something along these lines should get you your desired functionality.
