Can I use webpack and its bundling-features with an openUI5 project? How?

I am aware of openui5_preload and gulp-ui5-preload but I want more than just putting all my code in one preloader-file: I like to "walk" all used dedendencies as well and bundle my whole openUI5-project in one file.

So far I was able to get webpack running with UI5:

npm i -g webpack

webpack.config.js:

module.exports = {
  entry: {
    packed: './webapp/Component.js'
  },
  output: {
    path: './built',
    filename: '[name].built.js'
  },
  resolve: {
    modulesDirectories: [
      'node_modules',
      'bower_components'
    ]
  }
};

and run webpack a file built/packed.built.js is created. But it just contains my component.js-file. Why?

UI5 uses its own implementations/modifications of CommonJS and AMD: jQuery.sap.require()/jQuery.sap.declare() and the newer and now recommended AMD sap.ui.require()/sap.ui.declare().

Webpacks dependecy walking supports CommonJS and AMD (1). But i would guess that it does not understand the UI5 Modules. Without that it cannot extract the dependencies of each module. So its getting stuck at your Component.js...

I've just come across a presentation from UI5Con mentioning OpenUI5 Webpack support.

You install it with: npm install --save-dev openui5-webpack-plugin

Sample config taken from the project documentation:

const OpenUI5Plugin = require("openui5-webpack-plugin");
const CopyWebpackPlugin = require('copy-webpack-plugin');

module.exports = {
  resolve: {
    modules: [
      "node_modules/@openui5/sap.m/src",
      "node_modules/@openui5/sap.ui.core/src",
      "node_modules/@openui5/sap.ui.core/src/sap/ui/thirdparty",
      "node_modules/@openui5/themelib_sap_belize/src",
      "node_modules"
    ],
  },
  plugins: [
    new OpenUI5Plugin({
      modulePath: 'my/resource/module/path',
      libs: ['sap.ui.core', 'sap.m'],
      translations: ['en', 'de'],
      theme: ['sap_belize'],
      requireSync: [],
      manifest: "./manifest.json"
    }),
    new CopyWebpackPlugin([
      {
        context: path.resolve(__dirname, "node_modules/@openui5/sap.ui.core/src"),
        from: {
          glob: "sap/ui/core/themes/base/fonts/**",
        },
      },
      {
        context: path.resolve(__dirname, "node_modules/@openui5/themelib_sap_belize/src"),
        from: {
          glob: "sap/ui/core/themes/sap_belize_plus/fonts/**",
        },
      }
    ]),
  ]
}
