+Support configure the base path of the server.
+
+By default, the base path of the server is `/`, and users can access lynx bundle through `http://<host>:<port>/main.lynx.bundle`
+If you want to access lynx bundle through `http://<host>:<port>/foo/main.lynx.bundle`, you can change `server.base` to `/foo`
+
+example:
+
+```js
+import { defineConfig } from '@lynx-js/rspeedy';
+export default defineConfig({
+  server: {
+    base: '/dist',
+  },
+});
+```
