Description

Note: A JavaScript/JSX variant of the this TypeScript/JSX example can be found here. A plain JavaScript variant can be found here.

Demonstrates the use of the connect decorator function to connect custom components to a redux store. This app sets up a redux store with a root state object containing a string and a number property myString and myNumber. Two actions are supported by that store: SET_RANDOM_NUMBER sets myNumber to a random number, and TOGGLE_STRING sets myString to 'HelloWorld' or 'Another Hello World' depending on the actions' checked boolean property. It then creates instances of two components connected to the store:

The ExampleComponent is a custom component with a text property and a toggle event. The text property controls what text the component displays and is mapped to the myString property of the root state object. The toggle event can be triggered by the components CheckBox and is mapped to the TOGGLE_STRING action. Therefore checking/unchecking the check box toggles the message.

The FunctionalComponent is a functional component that produces a Composite that wraps a single Button widget. (It could also directly return a button, it is done this way to showcase the usage of the apply feature of connect.) The button's text property is mapped to the myNumber property of the root state object. The button's select event is mapped to the SET_RANDOM_NUMBER action. Therefore tapping the button changes its text.
