Type: (config: swc.Options, options: Options) => swc.Options | Promise<swc.Options>

Customize Storybook's SWC setup for Webpack-based projects enabled via the @storybook/addon-webpack5-compiler-swc addon based on the supported frameworks, except Angular, Create React App, Ember.js and Next.js.

import type { Options } from '@swc/core';
// Replace your-framework with the webpack-based framework you are using (e.g., react-webpack5)
import type { StorybookConfig } from '@storybook/your-framework';
const config: StorybookConfig = {
  framework: {
    name: '@storybook/your-framework',
    options: {},
  swc: (config: Options, options): Options => {
    return {
      // Apply your custom SWC configuration
export default config;


The options provided by SWC are only applicable if you've enabled the @storybook/addon-webpack5-compiler-swc addon.
