This package contains browser-side functionality shared amongst all the frameworks (React, RN, Vue, Ember, Angular, etc) in the old "v6" story store back-compatibility layer.

A framework calls the start(renderToCanvas, { render, decorateStory }) function and provides:

The renderToCanvas function, which tells Storybook how to render the result of a story function to the DOM
The render function, which is a default mapping of args to a story result in CSFv3
The decorateStory function, which tells Storybook how to combine decorators in the framework.

The start function will return a configure() function, which can be re-exported to be used in preview.js (deprecated), or automatically by the main.js:stories field to:

return a list of CSF files
[deprecated] make calls to the storiesOf API.
