Overriding Webpack, JS, SCSS for ZED on project level

Edit on GitHub

To override or expand core JS and SCSS files, you need to expand the oryx-for-zed building system with an additional config:

  • See Webpack for details on how to adjust the Webpack config and create aliases for core modules.
  • See JS for details on creating a new entry point, file naming, extending core JS files, and path for entry points.
  • See SCSS for details on how to create a new file with styles and how to build it with Webpack.
  • See TWIG for details on how to add output JS and CSS on a page.


Create a new javascript file in ./frontend/zed/build.js. Copy the code below to the file:

const oryx = require("@spryker/oryx");
const oryxForZed = require("@spryker/oryx-for-zed");
const path = require('path');
const merge = require('webpack-merge');
const mergeWithStrategy = merge.smartStrategy({
    plugins: 'prepend'

const myCustomZedSettings = mergeWithStrategy(oryxForZed.settings, {
    entry: {
        dirs: [path.resolve('./src/Pyz/Zed/')] // Path for entry points on project level

oryxForZed.getConfiguration(myCustomZedSettings).then(configuration => oryx.build(configuration));

oryx-for-zed building settings must be expanded with a path to ZED modules on the project level (line 11). Due to mergeWithStrategy, the default config with core paths is expanded with a path to the project level.

Use merge from Webpack (see the example above) instead of Object.assign(…). If you use Object.assign(…), entry points config will be fully overwritten.

If new packages have been installed for modules via npm, specify the path to the resolveModules option on the project level.


const myCustomZedSettings = mergeWithStrategy(oryxForZed.settings, {
    resolveModules: {
        dirs: [path.resolve('./src/Pyz/Zed/')]

After you have created the new build for ZED, specify the new commands in root package.json.


  scripts: {
    "zed": "node ./frontend/zed/build",
    "zed:watch": "node ./frontend/zed/build --dev",
    "zed:production": "node ./frontend/zed/build --prod"


To extend the core JS, there should be Webpack aliases for the core modules. To make the new aliases available, extend the Webpack configuration with the new aliases:

oryxForZed.getConfiguration(myCustomZedSettings).then(configuration => oryx.build(mergeWithStrategy(configuration, {
    resolve: {
        alias: {
            {%AliasName%}: 'path/to/module/assets' // Example: 'Gui/assets/Zed/js/**'

You can check the existing list of aliases in the webpack.config.js file of oryx-for-zed.


The newly created entry points for JS files should have suffix .entry, for example, my-module.entry.js). Webpack collects all entry points with this suffix.

Use the following path to add all new entry points for your project: ./src/Pyz/Zed/{%ModuleName%}/assets/Zed/js/*.entry.js.

To extend JS modules from the core level, use aliases. To add a JS module, follow the example:

// OR
var ModuleName = require('{%AliasName%}/path/to/file.js');


Use the following path to add all files with style: ./src/Pyz/Zed/{%ModuleName%}/assets/Zed/sass/*.scs. Webpack collects only those styles that were provided in the entry point (JS).

Add style files by following the example:

require('path/to/file.scss') // Example: '../sass/*.scss'

The generated CSS file will have the same naming as the JS entry point. For example, if JS entry point’s name is spryker-gui.entry.js, then CSS output will be spryker-gui.css.


Webpack generates each entry point as a separate JS file. If JS file is not added to the TWIG JS, it won’t work. Keep in mind, that file generated by Webpack JS doesn’t have .entry suffix, so instead of, for example, module-name.entry.js the name will be module-name.js:

<script src="{{ assetsPath('js/*.js') }}"></script>

The newly generated styles have to be added to the twig template too. Note that Webpack automatically renames the output css files with the JS entry point name:

<link rel="stylesheet" href="{{ assetsPath('css/*.css') }}">
