What is @storybook/builder-webpack5?

The @storybook/builder-webpack5 npm package is a builder for Storybook that uses Webpack 5 as its core bundling engine. It allows developers to configure Storybook to use Webpack 5 for building and serving their UI component stories. This package is particularly useful for projects that have already migrated to Webpack 5, ensuring compatibility and taking advantage of the latest features offered by Webpack.

  "core": {

    // Custom webpack configuration
    return config;
  }
}
