Motivation / Use-Case

Breaking Changes

Additional Info

When I tried webpack-subresource-integrity to inject integrities, I found that I couldn't add integrities to the style files if I also used mini-css-extract-plugin. due to the lack of hooks in mini-css-extract-plugin. Due to the lack of hooks in mini-css-extract-plugin, it is not possible to add additional attributes to the link tag.

#40

Usage

import MiniCssExtractPlugin from 'mini-css-extract-plugin'

MiniCssExtractPlugin.getHooks(compiler).beforeTagInsert.tap(
  "YourPluginName",
  (source, varNames) =>
    compiler.webpack.Template.asString([
      source,
      `${varNames.tag}.setAttribute("integrity",  __webpack_require__.sriHashes[${varNames.chunkId}]);`,
    ])
);
