Learning Redux

Using the preloaded Redux store state

Now that we have defined the window.__PRELOADED_STATE__ variable, all that's left to do is to use it when creating the store on the client side.

Open src/index.js and pass window.__PRELOADED_STATE__ to the configureStore() function:

const store = configureStore(window.__PRELOADED_STATE__)

In this case, we do not care that the code will not work on the server side, so it is fine to use window.
