Configuration

Rules

No loader rule is enabled by default. Activate following prepared rules you need in options.rules

options.rules.js

• Type: boolean || object
• default: false
• file types: js, jsx, mjs

Config:

• true or {} activates JavaScript support

options.rules.ts

• Type: boolean
• default: false
• file types: ts, tsx

Config:

• true will activate TypeScript support

options.rules.scss

• Type: boolean || object
• default: false
• file types: scss, css

Config:

• true or {} will activate scss support
• { publicPath: '../' } provide a separate public path for stylesheets. By default, webpack uses the value from 'output.publicPath'. (only relevant for production build)
• { implementation: require('node-sass') } gives the possibility to use 'node-sass' as sass implementation. (you have to add 'node-sass' as a dev-dependency in your project)

options.rules.hbs

• Type: boolean || object
• default: false
• file types: hbs

Config:

• true or {} will activate handlebars handlebars precompiled templates support
• { include: [] } additionally adds include config to rule
• { exclude: [] } additionally adds exclude config to rule

options.rules.woff

• Type: boolean || object
• default: false
• file types: woff, woff2

Config:

• true or {} will activate woff font support (in CSS files)
• { include: [] } additionally adds include config to rule
• { exclude: [] } additionally adds exclude config to rule

options.rules.font

• type: boolean || object
• default: false
• file types: eot, svg, ttf, woff, woff2

Config:

• true or {} will activate font support for eot, svg, ttf, woff & woff2 fonts (in CSS files)
• { include: [] } additionally adds include config to rule
• { exclude: [] } additionally adds exclude config to rule

⚠ Please use this rule with care. You have to configure includes and exclude when you also use woff and/or image loader. Otherwise, svg or woff files are processed with multiple configurations.

options.rules.image

• Type: boolean || object
• default: false
• file types: png, jpg, gif, svg

Config:

• true will activate image support
• { include: [] } additionally adds include config to rule
• { exclude: [] } additionally adds exclude config to rule

options.features

Enable some additional features

options.features.banner

• Type: boolean
• default: true

(only relevant for production build)

true will add a text banner with infos from package.json to the bundled js & css

options.features.bundleAnalyzer

• Type: boolean
• default: false

true will add the bundleAnalyser plugin and opens a browser window with the stats

options.features.theme

• Type: string || false
• default: false

A string will activate theming support:

• webpack uses ./src/ui.${theme} as entrypoint (instead of ./src/ui)
• a subfolder within assets is used for the output path and publicPath (/assets/${theme}/)

It makes sense to use a dynamic value e.g. an environment variable, as shown in the example configuration.

options.features.dynamicAlias

• Type: object || false
• default: false

A proper configured dynamicAlias feature will activate the DynamicAliasResolverPlugin which can change import paths in source files dynamically on compile time as desired.

Properties:

• options.features.dynamicAlias.search (string || RegExp) search term to be replaced (e.g. '/theme/light')
• options.features.dynamicAlias.replace (string) string as replacement (e.g. /theme/${theme})

Extending Configuration

Code Splitting

By default, all js imports from 'node_modules' are extracted to a 'vendors.js' to use in your view files.

Dynamically imported js files will be extracted to public/js/dynamic/. You may use them in a promise chain.

import('package-name').then((pack) => {
  // do something with 'pack'
});

import(
  /* webpackChunkName: "mychunk" */ 'package-name'
).then((pack) => {
  // do something with 'pack'
});

You may change the default configuration in webpackConfig.optimization.splitChunks
