## 常见问题

### 复杂组件长什么样？

下例展示了一个复杂组件，它会安装页面、两个组件、一个 Hook、一个日期格式化工具以及一个配置文件。

```json showLineNumbers
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "hello-world",
  "title": "Hello World",
  "type": "registry:block",
  "description": "A complex hello world component",
  "files": [
    {
      "path": "registry/new-york/hello-world/page.tsx",
      "type": "registry:page",
      "target": "app/hello/page.tsx"
    },
    {
      "path": "registry/new-york/hello-world/components/hello-world.tsx",
      "type": "registry:component"
    },
    {
      "path": "registry/new-york/hello-world/components/formatted-message.tsx",
      "type": "registry:component"
    },
    {
      "path": "registry/new-york/hello-world/hooks/use-hello.ts",
      "type": "registry:hook"
    },
    {
      "path": "registry/new-york/hello-world/lib/format-date.ts",
      "type": "registry:utils"
    },
    {
      "path": "registry/new-york/hello-world/hello.config.ts",
      "type": "registry:file",
      "target": "~/hello.config.ts"
    }
  ]
}
```

### 如何新增 Tailwind 颜色？

要新增颜色，需要在 `cssVars` 的 `light` 与 `dark` 下添加对应变量。

```json showLineNumbers {10-18}
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "hello-world",
  "title": "Hello World",
  "type": "registry:block",
  "description": "A complex hello world component",
  "files": [
    // ...
  ],
  "cssVars": {
    "light": {
      "brand-background": "20 14.3% 4.1%",
      "brand-accent": "20 14.3% 4.1%"
    },
    "dark": {
      "brand-background": "20 14.3% 4.1%",
      "brand-accent": "20 14.3% 4.1%"
    }
  }
}
```

CLI 会自动更新项目的 CSS 文件。更新后即可通过 `bg-brand`、`text-brand-accent` 等工具类使用新颜色。

### 如何新增或覆写 Tailwind 主题变量？

要添加或覆写主题变量，可在 `cssVars.theme` 中写入对应键值。

```json showLineNumbers {10-15}
{
  "$schema": "https://ui.shadcn.com/schema/registry-item.json",
  "name": "hello-world",
  "title": "Hello World",
  "type": "registry:block",
  "description": "A complex hello world component",
  "files": [
    // ...
  ],
  "cssVars": {
    "theme": {
      "text-base": "3rem",
      "ease-in-out": "cubic-bezier(0.4, 0, 0.2, 1)",
      "font-heading": "Poppins, sans-serif"
    }
  }
}
```
