This repository presents a workaround for angular/angular-cli#2688.

This project was generated with Angular CLI version 7.3.7.

Source: https://alligator.io/angular/custom-webpack-config/

Run npm run build:prod to build the project. The build artifacts will be stored in the dist/ directory. This will output the following stucture:

|_ dist
    |_ index.html
    |_ favicon.ico
    |_ app/
        |_ main.js
        |_ styles.js
        |_ ...

Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Run npm run serve:prod for checking production build locally. Navigate to http://localhost:4200/.

• npm i -D @angular-builders/custom-webpack
• angular.json > projects > your-project-name > architect > build > replace builder value by:
  • "builder": "@angular-builders/custom-webpack:browser"
• angular.json > projects > your-project-name > architect > build > options > outputPath:
  • Prepend output path with your subfolder, i.e. "outputPath": "dist/app"
• angular.json > projects > your-project-name > architect > build > options, add:

  "customWebpackConfig": { 
      "path": "./extra-webpack.config.js", 
      "replaceDuplicatePlugins": true 
  }`
  

• angular.json > projects > your-project-name > architect > build > configurations, add:

  "deployUrl": "app/",
  "baseHref": "",
  

• Create extra-webpack.config.js file at project root with the content below:

  const fs = require('fs');
  module.exports = (config, options) => {
      config.plugins.push({
          apply: (compiler) => {
              compiler.hooks.afterEmit.tap('MyAfterEmitPlugin', (compilation) => {
                  // Replace 'app' path below with your subfolder path
                  fs.renameSync('./dist/app/index.html', './dist/index.html');
                  fs.renameSync('./dist/app/favicon.ico', './dist/favicon.ico');
              });
          }
      });
      return config;
  };
  

This workaround works with deployments using context-path like http://hostname:xxxx/myapp
