@ComponentState decorator

Is used to inject actions into component

When component is created @ComponentState decorator creates does two things:

• Creates instance of state actions

• Assigns values to statePath and stateIndex taken from props

Component state takes 1 parameter but it can be either action class or function that resolves action class:

@ComponentState(TodosStateActions)

or

@ComponentState((component: TodosComponent) => {
  return component.isStateA
    ? A_StateActions
    : B_StateActions;
})
