How to exclude bootstrap files when CSS modules is enabled

I am using both bootstrap and CSS modules by enabling the css-loader's modules option in my project and unfortunately css-loader applys scoping on the bootstrap files too.

I have an app.scss where I am importing all bootstrap sass files. And I import the app.scss file into my app.js file:

import "./app.scss";

  { test: /\.scss$/,
    use: [
        {loader: "style-loader"},
        {
          loader: "css-loader",
          options: {
            sourceMap: true,
            modules: true,
            localIdentName: "[path][name]__[local]--[hash:base64:5]"
          }
        },
        {loader: "sass-loader"}
      ]

for example bootstrap's .table class turns to something like .app__table--19A_z

How do you think I can disable CSS modules for bootstrap files.

Yes Drew2 advice to look to githup issue is very helpful. Add a query to bootstrap css import path:

import 'bootstrap/dist/css/bootstrap.css?bootstrap'
import 'bootstrap/dist/js/bootstrap'
import App from './App'

And in webpack.config use "oneOf" for css rule:

    rules: [
  ...
  {
    test: /\.(css|pcss)$/,
    oneOf: [
      {
        resourceQuery: /bootstarp/,
        use: [
          'style-loader',
          {
            loader: 'css-loader',
            options: {
              sourceMap: true,
              importLoaders: 1,
            },
          },
          {
            loader: 'postcss-loader',
            options: { sourceMap: true },
          },
        ],
      },
      {
        use: [
          'style-loader',
          {
            loader: 'css-loader',
            options: {
              sourceMap: true,
              importLoaders: 1,
              modules: {
                localIdentName: mode === 'development' ? '[folder]_[name]_[local]_[hash:base64:5]' : '[hash:base64:8]',
              },
            },
          },
          {
            loader: 'postcss-loader',
            options: { sourceMap: true },
          },
        ],
      },
    ],
  },

  ...
],

OR with include/exclude:

import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap/dist/js/bootstrap'
import App from './App'


      rules: [
...
{
    test: /\.(css|pcss)$/,
    exclude: /bootstrap\/dist\/css\/bootstrap\.css$/,
    use: [
      'style-loader',
      {
        loader: 'css-loader',
        options: {
          sourceMap: true,
          importLoaders: 1,
          modules: {
            localIdentName: mode === 'development' ? '[folder]_[name]_[local]_[hash:base64:5]' : '[hash:base64:8]',
          },
          // exportOnlyLocals: false,
        },
      },
      {
        loader: 'postcss-loader',
        options: { sourceMap: true },
      },
    ],
  },

  {
    test: /\.(css|pcss)$/,
    include: /bootstrap\/dist\/css\/bootstrap\.css$/,
    use: [
      'style-loader',
      {
        loader: 'css-loader',
        options: {
          sourceMap: true,
          importLoaders: 1,
          // exportOnlyLocals: false,
        },
      },
      {
        loader: 'postcss-loader',
        options: { sourceMap: true },
      },
    ],
  },

... ]
