# server.publicRoutes

- **Type:** `Object`
- **Default:** Server-side routing rules generated based on file conventions, with one route rule generated for each file.

This configuration option only applies to server-side routing and can customize the access route of resources under `config/public/`.

The `key` of the object is the relative file path of the `config/public/` (without using `./`), and the value can be a `string`.

```ts title="modern.config.ts"
export default defineConfig({
  server: {
    publicRoutes: {
      // Set a long route
      'index.json': '/user-config/card-info/extra/help.json',

      // Set a route without a suffix
      'robot.txt': '/app/authentication',
    },
  },
});
```
