Instance Method Details

#redux_store(store_name, props: {}, **rest) ⇒ Object

Separate initialization of store from react_component allows multiple react_component calls to use the same Redux store.

store_name: name of the store, corresponding to your call to ReactOnRails.registerStores in your

JavaScript code.

props: Named parameter props which is a Ruby Hash or JSON string which contains the properties

to pass to the redux store.

Be sure to include view helper ‘redux_store_hydration_data` at the end of your layout or view or else there will be no client side hydration of your stores.
