Introducing the application state

After this brief tour into Redux, we will apply the newly obtained knowledge in practice. First, we will install the redux package:

npm i -S redux 

We will also use the additional helper library redux-act (https://github.com/pauldijou/redux-act) to simplify the declaration of action creators and reducers. By using this library, we can use the action creator functions as references within reducers, abandoning the switch( action.type ) construction in favor of a shorter map syntax:

npm i -S redux-act 

For screen capture, we should perform the following actions:

• SET_ACTIVE_TAB: It receives the identifier of the selected tab
• TOGGLE_RECORDING: It receives true when screencast recording starts and false when it ends
• SET_SCREENSHOT_FILENAME: It receives the output filename in the panel Screenshot
• SET_SCREENSHOT_INPUT_ERROR: It receives a message when an input error occurs
• SET_ANIMATION_FILENAME: It receives an output filename in the panel Animation
• SET_ANIMATION_INPUT_ERROR...
