This package contains common node-side functionality used among the different frameworks (React, RN, Vue, Ember, Angular, etc).
- CLI arg parsing
- Storybook UI "manager" webpack configuration
- presets handling
The "preview" (aka iframe) side is implemented in pluggable builders:
These builders abstract both the webpack dependencies as well as the various core configurations and loader/plugin dependencies provided out of the box with Storybook.
