19. extended components?
20. extended components? // use Vue.extend const BaseComponent = Vue.extend({ data () { return { lastname: 'murakami' } } }) new BaseComponent({ el: '#app', template: '<span>{{ firstname }}-{{ lastname }}</span>', data () { return { firstname: 'yamato' } } })
21. extended components? // use extends property const BaseComponent = { data () { return { lastname: 'murakami' } } } new Vue({ extends: BaseComponent, el: '#app', template: '<span>{{ firstname }}-{{ lastname }}</span>', data () { return { firstname: 'yamato' } } });
22. Test Code
23. extended components? const BaseComponent = Vue.extend({ data () { return { lastname: 'murakami' } } }) const ChildCompoent = BaseComponent.extend({ template: '<span>{{ firstname }}-{{ lastname }}</span>', data () { return { firstname: 'yamato' } } }) describe("ChildCompoent.vue", () => { it("renders fullname", () => { const wrapper = mount(ChildCompoent); expect(wrapper.text()).toMatch('yamato-murakami'); }); });
24. extended components?
26. Why extended components need to improve?

33. // use Vue.extend const BaseComponent = Vue.extend({ data () { return { lastname: 'murakami' } } }) BaseComponent.extend({ ~~~~~~~~~ some extend setting ~~~~~~~~~ })
34. // use Vue.extend const BaseComponent = Vue.extend({ data () { return { lastname: 'murakami' } } }) BaseComponent.extend({ ~~~~~~~~~ some extend setting ~~~~~~~~~ }) "

39. Why call `extend` twice?
40. Why call `extend` twice? const Component = { template: '<span></span>', computed: { returnZero () { return 0; } } } describe("Component.vue", () => { it("override", () => { const wrapper = mount(Component, { computed: { returnZero () { return 'Override!!' } } }); expect(wrapper.vm.returnZero).toBe('Override!!'); }); });
