路由组件类型增加
/**
* Interface for declaring custom options.
*
* @example
*
* declare module '@vue/runtime-core' {
* interface ComponentCustomOptions {
* beforeRouteUpdate?(
* to: Route,
* from: Route,
* next: () => void
* ): void
* }
* }
*
*/
`
vue实例内this扩展
/**
* Custom properties added to component instances in any way and can be accessed through `this`
*
* @example
* Here is an example of adding a property `$router` to every component instance:
* import { createApp } from 'vue'
* import { Router, createRouter } from 'vue-router'
*
* declare module '@vue/runtime-core' {
* interface ComponentCustomProperties {
* $router: Router
* }
* }
*
* // effectively adding the router to every component instance
* const app = createApp({})
* const router = createRouter()
* app.config.globalProperties.$router = router
*
* const vm = app.mount('#app')
* // we can access the router from the instance
* vm.$router.push('/')
