Convert Component

Convert an existing React component into a Webflow Code Component by analyzing its structure and generating the appropriate .webflow.tsx definition file.

When to Use This Skill

Use when:

• User has an existing React component they want to use in Webflow
• User asks to "convert", "adapt", or "make this work with Webflow"
• User provides a React component file and wants a Webflow definition
• User is migrating components from another React project

Do NOT use when:

• Creating a component from scratch (use component-scaffold)
• User just wants to understand code components (answer directly)
• Component is already a Webflow code component (use component-audit)

Instructions

Phase 1: Analyze Existing Component

1. Read the React component file: Get the full source code

2. Extract component information:

   • Component name (function/const name)
   • Props interface or type definition
   • Each prop's TypeScript type
   • Default values if defined
   • Whether component uses children

3. Identify incompatible patterns:

   Pattern	Issue	Resolution
   React Context usage	Context doesn't work across Webflow components	Refactor to props or use nano stores
   window/document in render	SSR will fail	Wrap in useEffect or set ssr: false
   localStorage/sessionStorage in render	SSR will fail	Wrap in useEffect or set ssr: false
   Complex object props	Can't map to Webflow prop types	Break into individual props
   Function props (callbacks)	Not supported in Webflow	Remove or internalize logic
   useContext hook	Won't work across components	Use alternative state patterns
   External CSS imports	May not work in Shadow DOM	Import in .webflow.tsx instead
   CSS class references to global styles	Won't work in Shadow DOM	Use component-scoped styles
   styled-components	Needs Shadow DOM decorator	Set up globals.ts with decorator
   Emotion (@emotion/styled)	Needs Shadow DOM decorator	Set up globals.ts with decorator

4. Detect styling approach and note required setup:

   If using styled-components:

   npm i @webflow/styled-components-utils styled-components

   Create/update globals.ts:

   import { styledComponentsShadowDomDecorator } from "@webflow/styled-components-utils";
   export const decorators = [styledComponentsShadowDomDecorator];

   If using Emotion:

   npm i @webflow/emotion-utils @emotion/cache @emotion/react

   Create/update globals.ts:

   import { emotionShadowDomDecorator } from "@webflow/emotion-utils";
   export const decorators = [emotionShadowDomDecorator];

   For both CSS-in-JS approaches, update webflow.json:

   styled-components:

   {
     "library": {
       "globals": "./src/globals.ts",
       "renderer": {
         "server": "@webflow/styled-components-utils/server"
       }
     }
   }

   Emotion:

   {
     "library": {
       "globals": "./src/globals.ts",
       "renderer": {
         "server": "@webflow/emotion-utils/server"
       }
     }
   }

5. Flag any dependencies that might cause issues:

   • Large libraries (bundle size concern)
   • Browser-only libraries
   • Libraries that manipulate DOM directly

Phase 2: Map Props to Webflow Types

6. Apply TypeScript → Webflow prop type mapping:

   TypeScript Type	Webflow Prop	Notes
   string	props.Text()	Default for short text
   string (long/HTML content)	props.RichText()	If prop name suggests content/body/description
   React.ReactNode / children	props.Slot()	For nested content
   number	props.Number()	Numeric values
   boolean	props.Boolean()	Toggles
   "option1" | "option2"	props.Variant()	String literal unions (requires options array)
   enum	props.Variant()	Convert enum values to options array (required)
   { href: string; ... }	props.Link()	Returns { href, target?, preload? } object — may need wrapper if component expects separate href/target props
   Image-related types	props.Image()	Image src, url, etc.
   string (canvas-editable text)	props.TextNode()	For text editable directly on canvas; has multiline param
   boolean (show/hide)	props.Visibility()	Semantic show/hide toggle
   string (for HTML id)	props.Id()	If prop is named "id" or used for accessibility
   Complex objects	SPLIT	Break into multiple simple props
   Functions/callbacks	REMOVE	Not supported
   Arrays	SPECIAL	May need component redesign

7. Handle special cases:

   Complex object props - Break them down:

   // Original
   interface Props {
     author: {
       name: string;
       avatar: string;
       bio: string;
     }
   }
   
   // Converted to flat props
   props: {
     authorName: props.Text({ name: "Author Name" }),
     authorAvatar: props.Image({ name: "Author Avatar" }),
     authorBio: props.RichText({ name: "Author Bio" })
   }

   Union types with more than simple strings:

   // Original - complex union
   type Size = "sm" | "md" | "lg" | { width: number; height: number };
   
   // Convert to Variant with only string options
   size: props.Variant({
     name: "Size",
     options: ["sm", "md", "lg", "custom"],
     defaultValue: "md"
   })
   // Note: Custom size would need additional Number props

   Optional props - Provide defaultValue for prop types that support it. Note: Link, Image, Slot, and Id do not accept defaultValue.

   // Original
   interface Props {
     title?: string;
   }
   
   // Converted - provide default for types that support it
   title: props.Text({
     name: "Title",
     defaultValue: ""  // Empty string or sensible default
   })

Phase 3: Check Project Setup

8. Verify Webflow setup exists:

   • Check for webflow.json in project root
   • Check for required dependencies (@webflow/webflow-cli, @webflow/data-types, @webflow/react)
   • If using styled-components/Emotion, check for decorator packages
   • If missing, offer to set up or direct to local-dev-setup skill

9. Determine file locations:

   • Identify where the original component lives
   • Determine where .webflow.tsx should be created (same directory)
   • Check for existing styles that need to be imported

Phase 4: Generate Definition File

10. Create the .webflow.tsx file:

import { declareComponent } from "@webflow/react";
import { props } from "@webflow/data-types";
import { ComponentName } from "./ComponentName";
// Import styles if they exist
import "./ComponentName.module.css"; // or .css

export default declareComponent(ComponentName, {
  name: "ComponentName",
  description: "[Generated from component purpose]",
  group: "[Appropriate category]",
  props: {
    // Mapped props here
  },
  // decorators: [], // Optional — per-component decorators (e.g., for CSS-in-JS Shadow DOM support)
  options: {
    applyTagSelectors: true, // Default is false. Set to true to apply Webflow's tag selectors (e.g., h1, p styles) inside the component.
    ssr: true // or false if browser APIs detected
  }
});

11. Provide the complete file with all props mapped

Phase 5: Document Required Changes

12. List modifications needed to the original component:

## Required Changes to [ComponentName].tsx

### Must Fix (Component won't work without these):
- [ ] Issue 1: [Description and how to fix]
- [ ] Issue 2: [Description and how to fix]

### Recommended (Will improve Webflow integration):
- [ ] Recommendation 1
- [ ] Recommendation 2

### Props Mapping Summary:
| Original Prop | Webflow Prop | Notes |
|---------------|--------------|-------|
| title: string | props.Text() | Direct mapping |
| isOpen: boolean | props.Boolean() | Direct mapping |
| data: object | SPLIT → dataTitle, dataValue | Flattened |
| onClick: function | REMOVED | Not supported |

13. Provide modified component code if changes are needed:
    • Show the updated TypeScript interface
    • Show any useEffect wrappers needed for SSR
    • Show style import changes
    • Note CSS-in-JS setup requirements if applicable

Examples

Example 1: Simple Component Conversion

User prompt:

Convert this React component to work with Webflow:

// TestimonialCard.tsx
interface TestimonialCardProps {
  quote: string;
  authorName: string;
  authorTitle?: string;
  rating?: number;
}

export const TestimonialCard: React.FC<TestimonialCardProps> = ({
  quote,
  authorName,
  authorTitle = "",
  rating = 5
}) => {
  return (
    <div className="testimonial-card">
      <div className="stars">{"★".repeat(rating)}</div>
      <blockquote>{quote}</blockquote>
      <div className="author">
        <strong>{authorName}</strong>
        {authorTitle && <span>{authorTitle}</span>}
      </div>
    </div>
  );
};

Response:

## Component Analysis: TestimonialCard

### Props Detected:
| Prop | TypeScript Type | Webflow Mapping |
|------|-----------------|-----------------|
| quote | string | props.Text() |
| authorName | string | props.Text() |
| authorTitle | string (optional) | props.Text() |
| rating | number (optional) | props.Number() |

### Issues Found:
- **CSS class "testimonial-card"** - Uses global class that won't work in Shadow DOM
  - Fix: Convert to CSS Modules or import scoped styles

### No blocking issues - ready to convert!

## Generated Files

### TestimonialCard.webflow.tsx
```typescript
import { declareComponent } from "@webflow/react";
import { props } from "@webflow/data-types";
import { TestimonialCard } from "./TestimonialCard";
import "./TestimonialCard.module.css";

export default declareComponent(TestimonialCard, {
  name: "TestimonialCard",
  description: "Display customer testimonials with rating stars",
  group: "Display",
  props: {
    quote: props.Text({
      name: "Quote",
      defaultValue: "This product changed my life!"
    }),
    authorName: props.Text({
      name: "Author Name",
      defaultValue: "Jane Doe"
    }),
    authorTitle: props.Text({
      name: "Author Title",
      defaultValue: "CEO, Company"
    }),
    rating: props.Number({
      name: "Rating",
      defaultValue: 5,
      min: 1,
      max: 5
    })
  },
  options: {
    applyTagSelectors: true,
    ssr: true
  }
});

Required Changes to TestimonialCard.tsx

1. Convert to CSS Modules - Rename TestimonialCard.css to TestimonialCard.module.css and update imports:

import styles from "./TestimonialCard.module.css";

// Default CSS Modules uses bracket notation:
<div className={styles["testimonial-card"]}>
<div className={styles["stars"]}>
// Dot notation (styles.testimonialCard) requires camelCase class names
// or a webpack override for css-loader.

Setup Check

• Verify webflow.json exists
• Install dependencies if needed: npm i --save-dev @webflow/webflow-cli @webflow/data-types @webflow/react

### Example 2: Component with Incompatible Patterns

**User prompt:**

Make this work as a Webflow code component:

// Modal.tsx import { createContext, useContext, useState } from 'react';

const ModalContext = createContext<{ isOpen: boolean; toggle: () => void } | null>(null);

export const useModal = () => { const context = useContext(ModalContext); if (!context) throw new Error('useModal must be used within ModalProvider'); return context; };

interface ModalProps { trigger: React.ReactNode; children: React.ReactNode; onOpen?: () => void; onClose?: () => void; }

export const Modal: React.FC<ModalProps> = ({ trigger, children, onOpen, onClose }) => { const [isOpen, setIsOpen] = useState(false);

const toggle = () => { const newState = !isOpen; setIsOpen(newState); if (newState && onOpen) onOpen(); if (!newState && onClose) onClose(); };

useEffect(() => { if (isOpen) { document.body.style.overflow = 'hidden'; } else { document.body.style.overflow = ''; } }, [isOpen]);

return ( <ModalContext.Provider value={{ isOpen, toggle }}> <div onClick={toggle}>{trigger}</div> {isOpen && ( <div className="modal-overlay" onClick={toggle}> <div className="modal-content" onClick={e => e.stopPropagation()}> {children} </div> </div> )} </ModalContext.Provider> ); };

**Response:**

```markdown
## Component Analysis: Modal

### Issues Found:

| Issue | Severity | Resolution |
|-------|----------|------------|
| React Context (ModalContext) | Critical | Context won't work across Webflow components. Since this is internal to Modal, it's OK but exported useModal hook won't work. |
| document.body manipulation | Critical | SSR incompatible. Must set `ssr: false` or wrap in useEffect check. |
| onOpen/onClose callbacks | Warning | Function props not supported in Webflow. Must remove. |
| Global CSS classes | Warning | "modal-overlay", "modal-content" won't work in Shadow DOM. |

### Props Detected:
| Prop | TypeScript Type | Webflow Mapping | Status |
|------|-----------------|-----------------|--------|
| trigger | React.ReactNode | props.Slot() | OK |
| children | React.ReactNode | props.Slot() | OK |
| onOpen | function | REMOVE | Not supported |
| onClose | function | REMOVE | Not supported |

---

## Required Changes

### 1. Remove function props (onOpen, onClose)
These cannot be passed from Webflow Designer. Remove from interface and component.

### 2. Fix SSR issue with document.body
Either set `ssr: false` or add typeof check:

```typescript
useEffect(() => {
  if (typeof document === 'undefined') return;
  // ... rest of effect
}, [isOpen]);

3. Convert to CSS Modules

Rename styles and update class references.

4. Remove exported useModal hook

This won't work for external components. Keep ModalContext internal only.

### Example 3: Component with Complex Object Props

**User prompt:**

Convert to Webflow:

interface Product { id: string; name: string; price: number; image: string; category: 'electronics' | 'clothing' | 'home'; }

interface ProductCardProps { product: Product; showBadge?: boolean; }

export const ProductCard = ({ product, showBadge = true }: ProductCardProps) => ( <div> <img src={product.image} alt={product.name} /> {showBadge && <span>{product.category}</span>} <h3>{product.name}</h3> <p>${product.price}</p> </div> );

**Response:**

```markdown
## Component Analysis: ProductCard

### Complex Props Detected:

The `product` prop is a complex object that must be flattened for Webflow:

| Original | Flattened Props |
|----------|-----------------|
| product.id | (Not needed in UI - remove) |
| product.name | productName: props.Text() |
| product.price | productPrice: props.Number() |
| product.image | productImage: props.Image() |
| product.category | productCategory: props.Variant() |
| showBadge | showBadge: props.Boolean() |

---

## Generated Files

### ProductCard.webflow.tsx
```typescript
import { declareComponent } from "@webflow/react";
import { props } from "@webflow/data-types";
import { ProductCard } from "./ProductCard";
import "./ProductCard.module.css";

export default declareComponent(ProductCard, {
  name: "ProductCard",
  description: "Product display card with image, name, price, and category",
  group: "Display",
  props: {
    productName: props.Text({
      name: "Product Name",
      defaultValue: "Product Title"
    }),
    productPrice: props.Number({
      name: "Price",
      defaultValue: 29.99
    }),
    productImage: props.Image({
      name: "Product Image"
    }),
    productCategory: props.Variant({
      name: "Category",
      options: ["electronics", "clothing", "home"],
      defaultValue: "electronics"
    }),
    showBadge: props.Boolean({
      name: "Show Category Badge",
      defaultValue: true
    })
  },
  options: {
    applyTagSelectors: true,
    ssr: true
  }
});

Updated ProductCard.tsx

import styles from "./ProductCard.module.css";

interface ProductCardProps {
  productName: string;
  productPrice: number;
  productImage?: { src: string; alt?: string };
  productCategory: 'electronics' | 'clothing' | 'home';
  showBadge?: boolean;
}

export const ProductCard = ({
  productName,
  productPrice,
  productImage,
  productCategory,
  showBadge = true
}: ProductCardProps) => (
  <div className={styles["card"]}>
    {productImage && (
      <img src={productImage.src} alt={productImage.alt || productName} />
    )}
    {showBadge && <span className={styles["badge"]}>{productCategory}</span>}
    <h3>{productName}</h3>
    <p>${productPrice.toFixed(2)}</p>
  </div>
);

Migration Notes:

• The product object has been flattened into individual props
• Each prop is now directly editable in Webflow Designer
• product.id was removed as it's not displayed in the UI
• Image prop now uses Webflow's Image type (provides { src, alt })

### Example 4: Component with styled-components

**User prompt:**

Convert this styled-components React component to Webflow:

// Button.tsx import styled from 'styled-components';

const StyledButton = styled.button<{ variant: 'primary' | 'secondary' }>` padding: 12px 24px; border-radius: 8px; font-weight: 600; background: ${props => props.variant === 'primary' ? '#3b82f6' : '#e5e7eb'}; color: ${props => props.variant === 'primary' ? 'white' : '#1f2937'};

&:hover { opacity: 0.9; } `;

interface ButtonProps { label: string; variant?: 'primary' | 'secondary'; disabled?: boolean; }

export const Button = ({ label, variant = 'primary', disabled = false }: ButtonProps) => ( <StyledButton variant={variant} disabled={disabled}> {label} </StyledButton> );

**Response:**

```markdown
## Component Analysis: Button

### Styling Approach Detected: styled-components

styled-components requires a Shadow DOM decorator to work in Webflow.

### Props Detected:
| Prop | TypeScript Type | Webflow Mapping |
|------|-----------------|-----------------|
| label | string | props.Text() |
| variant | 'primary' \| 'secondary' | props.Variant() |
| disabled | boolean | props.Boolean() |

### No blocking issues - ready to convert!

## Required Setup for styled-components

**1. Install dependencies:**
```bash
npm i @webflow/styled-components-utils styled-components
npm i -D @types/styled-components

2. Create/update src/globals.ts:

import { styledComponentsShadowDomDecorator } from "@webflow/styled-components-utils";
export const decorators = [styledComponentsShadowDomDecorator];

3. Update webflow.json:

{
  "library": {
    "name": "My Library",
    "components": ["./src/**/*.webflow.@(js|jsx|mjs|ts|tsx)"],
    "globals": "./src/globals.ts"
  }
}

Generated Files

Button.webflow.tsx

import { declareComponent } from "@webflow/react";
import { props } from "@webflow/data-types";
import { Button } from "./Button";
// No CSS import needed - styled-components handles styles

export default declareComponent(Button, {
  name: "Button",
  description: "Styled button with primary and secondary variants",
  group: "Interactive",
  props: {
    label: props.Text({
      name: "Label",
      defaultValue: "Click me"
    }),
    variant: props.Variant({
      name: "Variant",
      options: ["primary", "secondary"],
      defaultValue: "primary"
    }),
    disabled: props.Boolean({
      name: "Disabled",
      defaultValue: false,
      trueLabel: "Disabled",
      falseLabel: "Enabled"
    })
  },
  options: {
    applyTagSelectors: true,
    ssr: true
  }
});

No changes needed to Button.tsx

The component can remain as-is. The styled-components decorator in globals.ts will handle Shadow DOM style injection automatically.

Setup Checklist

• Install @webflow/styled-components-utils
• Create globals.ts with decorator
• Update webflow.json to reference globals
• Deploy with npx webflow library share

## Guidelines

### When to Recommend Component Redesign

Some components fundamentally don't fit the Webflow model:

1. **Heavy Context usage**: If component relies on app-wide context, suggest redesign
2. **Complex state machines**: May need simplification
3. **Tightly coupled components**: Each needs to be independent in Webflow
4. **Components that render portals**: Consider if portal is necessary

### Default Value Strategy

Always provide sensible defaults:
- Text props: Representative example text
- Numbers: Common/typical value
- Booleans: Most common use case
- Variants: Most popular option
- Images: Can be undefined (optional)
- Slots: No default needed

### Props Naming for Webflow

Make prop names designer-friendly:
- Use descriptive names: `buttonText` not `txt`
- Avoid abbreviations: `imageSource` not `imgSrc`
- Group related props with prefixes: `authorName`, `authorAvatar`, `authorBio`

### SSR Decision

Set `ssr: false` if component:
- Accesses `window`, `document`, `navigator`
- Uses `localStorage` or `sessionStorage`
- Manipulates DOM directly
- Uses libraries that require browser APIs
- Renders canvas, WebGL, or maps
