## Properties

| Property | Type | Description | Defined in |
| ------ | ------ | ------ | ------ |
|  `entry` | `string` | The prerender entry module, such as `./src/prerender.ts`. | [vite.ts:162](https://github.com/simshanith/lit-ui-router/blob/740888c2b2ba358c4dfa52a122e927df6a604b12/packages/ui-router-server/src/vite.ts#L162) |
|  `preload?` | readonly `string`\[] | Modules the worker loads, in order, before the entry, such as a DOM shim or a renderer's element registrations. A relative path resolves against Vite's root; a bare specifier resolves as the entry's imports do. | [vite.ts:168](https://github.com/simshanith/lit-ui-router/blob/740888c2b2ba358c4dfa52a122e927df6a604b12/packages/ui-router-server/src/vite.ts#L168) |
