Shared state is a library meant to provide shared state (duh) between Carrot's host app and templates. Shared state might include various preferences (and helper params such as custom oracle or KPI token template base URLs to aid in local development) or anything else that's deemed to be useful to share between host and templates.
The library is made to be as focused in scope as possible, and it's separated from other libraries to have fine grained control on what exactly gets shared with module federation across microfrontends. The library used for state management is Redux, which is framework agnostic and so supports various different frontend technologies.
The Redux state can be consumed using connectors exported by the library. The first and only implemented connector is for React and uses React Redux with a custom context shared between the host frontend and the templates.
