title: 入口文件
description: UI 扩展部分的入口文件
---

入口文件即 Halo 核心会加载的文件，所有插件有且只有一个入口文件，构建之后会放置在插件项目的 `src/resources/console` 下，名为 `main.js`。

为了方便开发者，我们已经在 [halo-dev/plugin-starter](https://github.com/halo-dev/plugin-starter) 配置好了基础项目结构，包括构建配置，后续文档也会以此为准。

## 定义入口文件

```ts title="ui/src/index.ts"
import { definePlugin } from "@halo-dev/console-shared";

export default definePlugin({
  components: {},
  routes: [],
  ucRoutes: [],
  extensionPoints: {}
});
```

## 类型定义

```ts
export function definePlugin(plugin: PluginModule): PluginModule {
  return plugin;
}
```

```ts title="PluginModule"

- `components`：组件列表，key 为组件名称，value 为组件对象，在此定义之后，加载插件时会自动注册到 Vue App 全局。
- `routes`：Console 控制台路由定义，详细文档可参考 [路由定义](../../api-reference/ui/route.md)
- `ucRoutes`：UC 个人中心路由定义，详细文档可参考 [路由定义](../../api-reference/ui/route.md)
- `extensionPoints`：扩展点定义，详细文档可参考 [扩展点](../../extension-points/ui/index.md)
