the Chinese documents of official website: https://router.vuejs.org/zh/api/interfaces/RouteMeta.html#%E6%8E%A5%E5%8F%A3-RouteMeta

接口:RouteMeta
路由记录中的 meta 字段的类型接口。
Example
// typings.d.ts 或 router.ts
import 'vue-router';

declare module 'vue-router' {
interface RouteMeta {
requiresAuth?: boolean
}
}

1. the first time i saw it, i felt that the object assigned to meta:{} must have the requiresAuth attribute to satisfy the structure type of TS.
2. i think we should directly follow the code in the router source code : interface RouteMeta extends Record<PropertyKey,unknown>{}
