        return 'product'
      }

  }),
  fromServer('./path/to/handler')
)

<script src="http://my.domain.com/.powerlinks.js" defer />

6.12.0

• Improved offline support.
• Users will now be able to navigate back to any page they have previously visited when offline.
• The AppBar component now displays "Your device lost its internet connection" when offline. This message is configurable via AppBar's offlineWarning prop.
• Added an Offline component to be displayed as the main body of the app when the user attempts to navigate to a page that isn't cached when offline.
• Added appShell configuration method to Router. Configure the appShell with a fromServerhandler that returns global data to display in the app shell when the user attempts to load the site while offline.

To add offline support to your app, upgrade to 6.12.0, then:

• Add an appShell configuration to your router definition:

// src/routes.js

new Router()
  // ...
  .appShell(
    // returns only the global data needed to build the app-shell for offline support
    fromServer('./app-shell/app-shell-handler')
  )

• Add the Offline component to your Pages element in App.js.

// src/App.js

import Offline from 'react-storefront/Offline'

// then in the render method...
class App extends Component {
  render() {
    return (
      <Pages
        components={universal => ({
          // ...
          Offline
        })}
      />
    )
  }
}

6.11.0

• Gracefully handle when history.replace fails due to the state object being too large. This was happening on Firefox for apps with large state trees as Firefox imposes a limit of 640kB on the state object. When history.replace fails, history.state will simply be cleared out and the app will get the state from the network if the user navigates back or forward.
