In this chapter, we familiarized ourselves with the basics of Google's Material Design. We built the static prototype from ready-made React components of the Material-UI set. We had an introduction into the Redux state container. We defined our application state tree and set state mutators. We created the global state store and connected it to the container component. We passed exposed action creators and state tree trunk into presentation components with the props. We examined shorter action/reducer declaration syntaxes provided by the redux-act library. We implemented it by using Redux state machine actions, such as tabbed navigation, recording toggle, and form validation.
