Infer store module types automatically
Remove the need to define the type of store created by each module manually by adding a `StoreFromModule` helper in `create-store.js` which can infer the store type from a store module configuration. Using this the type of a store composed from several modules can then be created with: ``` import fooModule from './modules/foo'; import barModule from './modules/bar'; // Define type of store returned by `createStore([fooModule, barModule])` /** @typedef {StoreType<fooModule> & StoreType<barModule>} AppStore */ ``` Ideally `createStore` would just infer the type based upon its arguments. I haven't worked out how to do that yet. Nevertheless, this still removes the need for a lot of manually defined types. To ensure more useful error messages from TS if a store module's configuration has the wrong shape a `storeModule` helper has been added. This wraps the configuration for each module to check its shape before the individual modules are combined into one type for the store. This helper could also perform runtime validation in future. - Add `StoreFromModule` type in `create-store.js` and several helpers to support it - Modify each store module to wrap the export in `storeModule` and remove any manually defined store types
