How to exclude Bootstrap framework?

[Mukhammad Akilov]

How can I exclude Bootstrap framework?
postcss.config.js file:

module.exports = { plugins: [ require('autoprefixer'), require('css-mqpacker'), require('cssnano')({ preset: [ 'default', { discardComments: { removeAll: true, } } ] }) ] }

webpack.config.js
{ test: /\.scss$/, use: [ 'style-loader', MiniCssExtractPlugin.loader, { loader: 'css-loader', //options: {sourceMap: true} }, { loader: 'postcss-loader', options: { //sourceMap: true, config: { path: 'assets/js/postcss.config.js' } } }, { loader: 'sass-loader', } ] }
