+# Resolving Routes
+
+## Getting all routes
+
+You can make use of [useRoutes](../../reference/client-api.md#useroutes) to get all routes information.
+
+The return value of `useRoutes` is a Ref object containing all routes. The keys are route paths of each route, and the values are the corresponding route information.
+
+```ts
+import { useRoutes } from 'vuepress/client'
+
+const routes = useRoutes()
+// {
+// '/': { meta: { title: 'Home' }, loader: HomePageLoader },
+// '/404.html': { meta: { title: 'Not Found' }, loader: NotFoundPageLoader },
+// ...
+// }
+
+const routePaths = computed(() => Object.keys(routes.value))
+// => ['/‘, '/404.html', '/foo/', '/bar/', ...]
+```
+
+## Resolving route path
+
+You can make use of [resolveRoutePath](../../reference/client-api.md#resolveroutepath) to resolve the route path of the given link.
+
+`resolveRoutePath` receives a link and an optional base path, and returns the resolved route path:
+
+```ts
+import { resolveRoutePath } from 'vuepress/client'
+
+const routePath = resolveRoutePath('/foo/') // => '/foo/'
+const routePath = resolveRoutePath('baz.html', '/foo/bar.html') // => '/foo/baz.html'
+```
+
+## Resolving route information
+
+You can make use of [resolveRoute](../../reference/client-api.md#resolveroute) to resolve route information for a given link.
+
+`resolveRoute` receives a link and an optional base path, and returns the resolved route information:
+
+```ts
+import { resolveRoute } from 'vuepress/client'
+
+const route = resolveRoute('/foo/') // => { notFound: false, path: '/foo/', meta: { title: 'Foo' }, loader: FooPageLoader }
+const route = resolveRoute('baz.html', '/foo/bar.html') // => { notFound: false, path: '/foo/baz.html', meta: { title: 'Baz' }, loader: BazPageLoader }
+const route = resolveRoute('/not-exist.html') // => { notFound: true, path: '/not-exist.html', meta: { title: 'Not Found' }, loader: NotFoundPageLoader }
+```
+
+There is a `notFound` field in the returned information, which is used to indicate whether a corresponding route exists for a given path. When the route does not exist, the `notFound` field would be `true`, the `path` field would be the normalized path, and the `meta` and `loader` fields would point to the default 404 page.

 - `themeConfig` is removed from user config and site data. To access the `themeConfig` as you would via `this.$site.themeConfig` in v1, we now recommend using the [@vuepress/plugin-theme-data](https://ecosystem.vuejs.press/plugins/theme-data.html) plugin and its `useThemeData` composition API.
 - Stylus is no longer the default CSS pre-processor, and the stylus palette system is not embedded. If you still want to use similar palette system as v1, [@vuepress/plugin-palette](https://ecosystem.vuejs.press/plugins/palette.html) may help.
 - Markdown code blocks syntax highlighting by Prism.js is not embedded by default. You can use either [@vuepress/plugin-prismjs](https://ecosystem.vuejs.press/plugins/prismjs.html) or [@vuepress/plugin-shiki](https://ecosystem.vuejs.press/plugins/shiki.html), or implement syntax highlighting in your own way.

+# 解析路由
+
+## 获取全部路由
+
+在开发主题和插件时，你可能希望获取所有页面的信息。通过 [useRoutes](../../reference/client-api.md#useroutes) 就可以获取所有页面的路由记录。
+
+`useRoutes` 的返回值是一个包含了所有路由信息的 Ref 对象。其属性是每条路由的路由路径，对应的值是路径的路由信息。
+
+```ts
+import { useRoutes } from 'vuepress/client'
+
+const routes = useRoutes()
+// {
+//   '/': { meta: { title: 'Home' }, loader: HomePageLoader },
+//   '/404.html': { meta: { title: 'Not Found' }, loader: NotFoundPageLoader },
+//   ...
+// }
+
+const routePaths = computed(() => Object.keys(routes.value))
+// => [’/‘, '/404.html', '/foo/', '/bar/', ...]
+```
+
+## 解析路由地址
+
+你可以使用 [resolveRoutePath](../../reference/client-api.md#resolveroutepath) 来解析给定的链接对应的路由路径。
+
+`resolveRoutePath` 接收一个链接地址和一个可选的基础路径，返回一个解析后的路由地址:
+
+```ts
+import { resolveRoutePath } from 'vuepress/client'
+
+const routePath = resolveRoutePath('/foo/') // => '/foo/'
+const routePath = resolveRoutePath('baz.html', '/foo/bar.html') // => '/foo/baz.html'
+```
+
+## 解析路由信息
+
+你可以使用 [resolveRoute](../../reference/client-api.md#resolveroute) 来解析给定的链接对应的路由信息。
+
+`resolveRoute` 接收一个链接地址和一个可选的基础路径，返回一个解析后的路由信息:
+
+```ts
+import { resolveRoute } from 'vuepress/client'
+
+const route = resolveRoute('/foo/') // => { notFound: false, path: '/foo/', meta: { title: 'Foo' }, loader: FooPageLoader }
+const route = resolveRoute('baz.html', '/foo/bar.html') // => { notFound: false, path: '/foo/baz.html', meta: { title: 'Baz' }, loader: BazPageLoader }
+const route = resolveRoute('/not-exist.html') // => { notFound: true, path: '/not-exist.html', meta: { title: 'Not Found' }, loader: NotFoundPageLoader }
+```
+
+路由信息中存在一个 `notFound` 字段，用于标识给定的路径是否存在对应的路由。当路由不存在时，返回值中的 `notFound` 字段为 `true`，其 `path` 字段为规范化后的路径，而 `meta` 和 `loader` 字段则会指向默认的 404 页面。
