Composition

You can compose multiple stores together using class inheritance. This is quite simple:
@State({
  name: 'zoo',
  defaults: {
    type: null
  }
})
@Injectable()
class ZooState {
  @Action(Eat)
  eat(ctx: StateContext) {
    ctx.setState({ type: 'eat' });
  }
}
​
@State({
  name: 'stlzoo'
})
@Injectable()
class StLouisZooState extends ZooState {
  @Action(Drink)
  drink(ctx: StateContext) {
    ctx.setState({ type: 'drink' });
  }
}
Now when StLouisZooState is invoked, it will share the actions of the ZooState. Also all state options are inherited.
