Migrate from Vue 1.x to 2.x
Migrate from Vue Router 0.7.x to 2.x
Migrate from Vuex 0.6.x to 1.0(2.0)

    Not much change in writing style.
    We provide you with two writing methods, you can use them according to your situation

    const router = new VueRouter({ .... }) ... // 第一种写法 const app = new Vue({ router, ...App // 扩展 }).$mount('#app') // 第二种 new Vue({ el: '#app', router, template: '', components: { App } })

    In additionVue.extendis to use the basic Vue constructor to create a "subclass". The parameter is an object containing the component's options.
    Look at the source code and it will be clear at a glance. global-api/extend
