Webpack configuration files

webpack.config.js

Add a webpack.config.js file in your project root. This is the configuration for the development environment.

import { fileURLToPath } from 'node:url'
import path from 'node:path'
import { createRequire } from 'node:module'

import { generateConfiguration, DEFAULT_DEVELOPMENT } from '@jenssimon/webpack-config-sfcc'
import cartridges from './webpack.cartridges.js'

const require = createRequire(import.meta.url)
const filename = fileURLToPath(import.meta.url)
const dirname = path.dirname(filename)

export default () => Object.entries(cartridges).map(([cartridge, config]) => generateConfiguration(cartridge, {
  dirname,
  resolver: require.resolve,
  ...DEFAULT_DEVELOPMENT,
  ...config,
}))

webpack.config.prod.js

Add a webpack.config.prod.js file in your project root. This is the configuration for the production environment.

/**
 * Webpack configuration for production build.
 */
import { generateConfiguration, DEFAULT_PRODUCTION } from '@jenssimon/webpack-config-sfcc'
import cartridges from './webpack.cartridges.js'

export default (env) => Object.entries(cartridges).map(([cartridge, config]) => generateConfiguration(cartridge, {
  ...DEFAULT_PRODUCTION,
  ...config,
  env,
}))

webpack.cartridges.js

Add a webpack.cartridges.js file in yout project root. This files contains specific additional configuration for each storefront cartridge within your project.

  // ...
}

resolver
