Question: Is there any way to only extract the css files from initial chunk?

I don’t think the browser needs to make extra an request to fetch the css file of its own async js chunk which it has been loaded. So I want to disable. It should be something like the “fallback” option of extract-text-webpack-plugin and its behavior. However, I’m not able to find an equivalent way with mini-css-extract-plugin and webpack 4.

For example, let’s say we have several pages will be loaded on demand:

// routes.js inside intial-chunk.js
import './initial-chunk.css';
const routes: [
  {
    module: () => import('pageA')
  }
];

// pageA.js
import './pageA.css';
export default {
  // something that pageA should do
};

// pageB.js
import './pageB.css';
export default {
  // something that pageB should do
};

And the output files should be like this:

vendor.js
initial-chunk.js
initial-chunk.css
pageA.js
pageB.js
// Note that there isn't a "pageA.css" or "pageB.css" file. These css files are inside their own chunks and loaded by some other loaders, `style-loader` for example

How can I achieve this? Thank you very much.

Was there a resolution on this? We have a bunch of dynamic imports, and they’re each getting their own CSS files and I’d like to bubble them up to their closest entrypoint, but haven’t been able to find the right config to achieve it.

No, I want to load css modules only when you need
