Install the Master CSS and Angular custom webpack plugin into your project via package managers.
npm i @master/css.webpack@rc @angular-builders/custom-webpackSet up CSS extractor

webpack.config.jsfile - Add a
MasterCSSExtractorPluginto the plugins
const { MasterCSSExtractorPlugin } = require('@master/css.webpack') module.exports = (config) => { config.plugins.push( new MasterCSSExtractorPlugin({ sources: ['src/index.html'] }) ) return config } Configure Angular
Use @angular-builders/custom-webpack instead of the default extractor for custom webpack configuration.
