设计稿转组件

将设计规范转换为像素级精准、可用于生产环境的 React 组件。

核心工作流

1. 分析设计规范：提取间距、颜色、排版和尺寸
2. 映射到设计令牌：将设计值转换为设计系统令牌
3. 生成结构：创建语义化 HTML 结构
4. 应用样式：使用 Tailwind/CSS 实现精确尺寸
5. 添加状态：包含悬停、焦点、激活和禁用状态
6. 处理响应式设计：实现特定断点规则
7. 确保无障碍性：添加 ARIA 标签和键盘导航
8. 记录变体：列出所有视觉状态和属性

设计令牌映射

创建令牌系统

// tokens.ts
export const tokens = {
  colors: {
    primary: {
      50: "#eff6ff",
      100: "#dbeafe",
      500: "#3b82f6",
      600: "#2563eb",
      700: "#1d4ed8",
    },
    gray: {
      100: "#f3f4f6",
      300: "#d1d5db",
      500: "#6b7280",
      700: "#374151",
      900: "#111827",
    },
  },
  spacing: {
    xs: "0.25rem", // 4px
    sm: "0.5rem", // 8px
    md: "1rem", // 16px
    lg: "1.5rem", // 24px
    xl: "2rem", // 32px
  },
  fontSize: {
    xs: ["0.75rem", { lineHeight: "1rem" }],
    sm: ["0.875rem", { lineHeight: "1.25rem" }],
    base: ["1rem", { lineHeight: "1.5rem" }],
    lg: ["1.125rem", { lineHeight: "1.75rem" }],
    xl: ["1.25rem", { lineHeight: "1.75rem" }],
  },
  borderRadius: {
    sm: "0.25rem", // 4px
    md: "0.375rem", // 6px
    lg: "0.5rem", // 8px
    full: "9999px",
  },
  shadows: {
    sm: "0 1px 2px 0 rgb(0 0 0 / 0.05)",
    md: "0 4px 6px -1px rgb(0 0 0 / 0.1)",
    lg: "0 10px 15px -3px rgb(0 0 0 / 0.1)",
  },
};

Tailwind 配置

// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      colors: {
        primary: {
          50: "#eff6ff",
          100: "#dbeafe",
          500: "#3b82f6",
          600: "#2563eb",
          700: "#1d4ed8",
        },
      },
      spacing: {
        18: "4.5rem",
        88: "22rem",
      },
      fontSize: {
        "2xs": "0.625rem",
      },
    },
  },
};

组件转换示例

根据 Figma 规范制作按钮

Figma 规范：

• 高度：40px
• 内边距：12px 24px
• 边框圆角：6px
• 字体：Inter Medium 14px
• 背景：#3B82F6
• 文本：#FFFFFF
• 悬停：#2563EB
• 阴影：0 1px 3px rgba(0,0,0,0.1)

转换后的组件：

import { cn } from "@/lib/utils";

interface ButtonProps extends React.ButtonHTMLAttributes<HTMLButtonElement> {
  variant?: "primary" | "secondary";
  size?: "sm" | "md" | "lg";
}

export const Button = ({
  variant = "primary",
  size = "md",
  className,
  children,
  ...props
}: ButtonProps) => {
  return (
    <button
      className={cn(
        // Base styles
        "inline-flex items-center justify-center rounded-md font-medium",
        "transition-colors duration-200",
        "focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-primary-500 focus-visible:ring-offset-2",
        "disabled:pointer-events-none disabled:opacity-50",
        // Variant: Primary (matches Figma)
        variant === "primary" && [
          "bg-primary-500 text-white shadow-sm",
          "hover:bg-primary-600",
          "active:bg-primary-700",
        ],
        // Size: Medium (40px height, 12px 24px padding)
        size === "md" && "h-10 px-6 text-sm",
        className
      )}
      {...props}
    >
      {children}
    </button>
  );
};

根据设计规范制作卡片

Figma 规范：

• 内边距：24px
• 边框圆角：12px
• 背景：#FFFFFF
• 边框：1px solid #E5E7EB
• 阴影：0 1px 3px rgba(0,0,0,0.1)
• 最大宽度：400px

转换后的组件：

interface CardProps extends React.HTMLAttributes<HTMLDivElement> {
  elevated?: boolean;
}

export const Card = ({
  elevated = false,
  className,
  children,
  ...props
}: CardProps) => {
  return (
    <div
      className={cn(
        // Base from Figma
        "max-w-sm rounded-xl bg-white p-6",
        "border border-gray-200",
        // Conditional shadow
        elevated ? "shadow-lg" : "shadow-sm",
        // Hover state (not in Figma, but good UX)
        "transition-shadow duration-200 hover:shadow-md",
        className
      )}
      {...props}
    >
      {children}
    </div>
  );
};

交互状态

悬停状态

// Figma: Background changes from #3B82F6 to #2563EB on hover
className={cn(
  'bg-primary-500',
  'hover:bg-primary-600',
  'transition-colors duration-200'
)}

焦点状态

// Accessible focus ring
className={cn(
  'focus:outline-none',
  'focus-visible:ring-2 focus-visible:ring-primary-500 focus-visible:ring-offset-2'
)}

激活/按下状态

// Figma: Slightly darker on click
className={cn(
  'active:bg-primary-700',
  'active:scale-[0.98]', // Slight scale down
  'transition-all duration-100'
)}

禁用状态

// Figma: 50% opacity, no interactions
className={cn(
  'disabled:opacity-50',
  'disabled:cursor-not-allowed',
  'disabled:pointer-events-none'
)}

响应式设计转换

断点映射

// Figma artboards → Tailwind breakpoints
// Mobile (375px): default (no prefix)
// Tablet (768px): md:
// Desktop (1024px): lg:
// Wide (1280px): xl:

<div
  className={cn(
    // Mobile: Stack vertically, full width
    "flex flex-col gap-4 w-full",
    // Tablet: Side by side, 50% each
    "md:flex-row md:gap-6",
    // Desktop: Max width container
    "lg:max-w-6xl lg:mx-auto"
  )}
/>

响应式排版

// Figma mobile: 14px, desktop: 16px
<h1 className="text-sm md:text-base lg:text-lg font-semibold">
  Responsive Heading
</h1>

响应式间距

// Figma mobile: 16px padding, desktop: 24px
<div className="p-4 md:p-6 lg:p-8">Content</div>

设计系统集成

使用 shadcn/ui 模式

// Leveraging shadcn's composable approach
import { cn } from "@/lib/utils";

const buttonVariants = cva(
  "inline-flex items-center justify-center rounded-md text-sm font-medium transition-colors focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2 disabled:opacity-50 disabled:pointer-events-none ring-offset-background",
  {
    variants: {
      variant: {
        default: "bg-primary text-primary-foreground hover:bg-primary/90",
        destructive:
          "bg-destructive text-destructive-foreground hover:bg-destructive/90",
        outline:
          "border border-input hover:bg-accent hover:text-accent-foreground",
        secondary:
          "bg-secondary text-secondary-foreground hover:bg-secondary/80",
        ghost: "hover:bg-accent hover:text-accent-foreground",
        link: "underline-offset-4 hover:underline text-primary",
      },
      size: {
        default: "h-10 py-2 px-4",
        sm: "h-9 px-3 rounded-md",
        lg: "h-11 px-8 rounded-md",
        icon: "h-10 w-10",
      },
    },
    defaultVariants: {
      variant: "default",
      size: "default",
    },
  }
);

颜色系统转换

从 Figma 转换为 CSS 变量

/* Figma colors → CSS variables */
:root {
  /* Primary from Figma #3B82F6 */
  --primary: 221 83% 60%;
  --primary-foreground: 0 0% 100%;

  /* Secondary from Figma #6B7280 */
  --secondary: 220 9% 46%;
  --secondary-foreground: 0 0% 100%;

  /* Backgrounds */
  --background: 0 0% 100%;
  --foreground: 222 47% 11%;

  /* Borders */
  --border: 220 13% 91%;
  --input: 220 13% 91%;
  --ring: 221 83% 60%;

  /* Radius from Figma */
  --radius: 0.5rem;
}

在组件中使用

<div className="bg-background text-foreground border-border">
  <button className="bg-primary text-primary-foreground">Button</button>
</div>

动画与过渡

根据 Figma 设计制作微交互

// Figma: Button scales slightly on hover
<button className={cn(
  'transition-all duration-200',
  'hover:scale-105',
  'active:scale-95'
)}>
  Hover me
</button>

// Figma: Card lifts on hover
<div className={cn(
  'transition-all duration-300',
  'hover:-translate-y-1 hover:shadow-lg'
)}>
  Card content
</div>

// Figma: Fade in on mount
<div className="animate-in fade-in duration-500">
  Fading content
</div>

尺寸转换

Figma 像素 → Tailwind 类

Figma	Tailwind	值
2px	0.5	0.125rem
4px	1	0.25rem
8px	2	0.5rem
12px	3	0.75rem
16px	4	1rem
20px	5	1.25rem
24px	6	1.5rem
32px	8	2rem
40px	10	2.5rem
48px	12	3rem

自定义值

// Figma: 18px (not in default Tailwind)
<div className="w-[18px] h-[18px]">{/* or add to config */}</div>

无障碍映射

从视觉设计到无障碍

// Figma shows disabled state
<button
  disabled={isDisabled}
  aria-disabled={isDisabled}
  className={cn(
    isDisabled && 'opacity-50 cursor-not-allowed'
  )}
>
  Submit
</button>

// Figma shows error state
<input
  aria-invalid={hasError}
  aria-describedby={hasError ? 'error-message' : undefined}
  className={cn(
    hasError && 'border-red-500 focus:ring-red-500'
  )}
/>

常见模式

表单输入框转换

Figma 规范：

• 高度：44px
• 内边距：12px 16px
• 边框：1px #D1D5DB
• 边框圆角：8px
• 焦点边框：2px #3B82F6

<input
  className={cn(
    "h-11 w-full rounded-lg border border-gray-300 px-4",
    "text-base text-gray-900 placeholder:text-gray-500",
    "focus:border-primary-500 focus:ring-2 focus:ring-primary-500 focus:ring-offset-0",
    "disabled:cursor-not-allowed disabled:opacity-50"
  )}
/>

图标按钮转换

Figma 规范：

• 尺寸：40x40px
• 图标：居中显示，尺寸为 20x20px
• 边框圆角：8px
• 悬停背景：#F3F4F6

<button
  className={cn(
    "flex h-10 w-10 items-center justify-center rounded-lg",
    "text-gray-700 transition-colors",
    "hover:bg-gray-100",
    "focus-visible:ring-2 focus-visible:ring-primary-500"
  )}
>
  <Icon className="h-5 w-5" />
</button>

最佳实践

1. 反复核对：确认所有尺寸都与 Figma 完全一致
2. 使用设计令牌：映射到令牌，而不是硬编码数值
3. 覆盖所有状态：包括悬停、聚焦、激活、禁用和错误状态
4. 响应式设计：实现设计中的所有断点
5. 无障碍访问：在 Figma 显示状态的地方添加 ARIA
6. 动画：使过渡时长与设计一致
7. 深色模式：如果有相关设计，使用类变体实现
8. 组件变体：创建可复用的变体属性
9. 文档：记录与设计不一致之处
10. 评审：取得设计师对实现的认可

输出检查清单

每次从设计到组件的转换都应包括：

• 间距与 Figma 尺寸完全一致
• 字体排印的字号比例和字重
• 设计系统中的所有颜色值
• 边框圆角和阴影
• 悬停状态样式
• 聚焦状态样式（无障碍）
• 激活/按下状态样式
• 禁用状态样式
• 响应式断点规则
• 设计令牌映射文档
• 无障碍属性
• 各状态的组件变体
