Advanced tools
Storybook Core-Common
Common utilities used across @storybook/core-server (manager UI configuration) and @storybook/builder-webpack{4,5} (preview configuration).
This is a lot of code extracted for convenience, not because it made sense.

webpack-merge
While not a Storybook-specific package, webpack-merge is often used in conjunction with @storybook/core-webpack for merging custom Webpack configurations with Storybook's default. It provides a streamlined way to combine configurations, which is essential for complex setups.
customize-cra
customize-cra is designed for overriding Create React App's Webpack configurations without 'ejecting'. It offers a similar value proposition to @storybook/core-webpack but is specifically tailored for CRA projects.
