Component Audit

Audit existing code components for Webflow-specific architecture decisions. This skill focuses on how well components integrate with Webflow Designer, not generic React best practices.

When to Use This Skill

Use when:

• User wants to improve how their components work in Webflow Designer
• Reviewing whether the right things are exposed as props vs hardcoded
• Checking if state management patterns are Webflow-compatible
• Looking for opportunities to make components more designer-friendly
• Component isn't rendering or behaving as expected in Webflow

Do NOT use when:

• Validating before deployment (use pre-deploy-check instead)
• Creating new components (use component-scaffold instead)
• Converting a React component (use convert-component instead)
• Generic code quality review (use a linter)

Core Philosophy

This audit answers three questions:

1. Designer Control: Are the right things exposed as props for designers to customize?
2. Webflow Compatibility: Does the component work within Webflow's constraints (Shadow DOM, SSR, isolated React roots)?
3. Component Architecture: Is this the right level of granularity, or should it be split/combined?

Instructions

Phase 1: Discovery

1. Find all components:

   • Locate webflow.json
   • Find all .webflow.tsx files
   • Read corresponding React components

2. Understand intent: Ask user what the components are for and any specific concerns

Phase 2: Analysis

For each component, analyze these Webflow-specific areas:

A. Prop Exposure Analysis

Goal: Identify what designers SHOULD be able to control but currently can't.

Look For	Recommendation
Hardcoded text strings	Expose as props.Text()
Text that designers should edit on canvas	Expose as props.RichText()
Hardcoded values from a fixed set of options	Expose as props.Variant({ options: [...] })
Hardcoded image URLs	Expose as props.Image()
Hardcoded link URLs	Expose as props.Link()
Hardcoded HTML id attributes	Expose as props.Id()
Conditional rendering with boolean	Expose as props.Boolean() or props.Visibility()
Internal state that affects appearance	Consider exposing initial value as prop
children not using Slot	Convert to props.Slot()

Aliases: props.String = props.Text, props.Children = props.Slot. Treat these as equivalent during audit.

Questions to ask:

• "What would a designer want to change?"
• "What requires a code change that shouldn't?"

B. State Management Architecture

Goal: Identify patterns that won't work in Webflow.

Anti-Pattern	Why It Fails	Alternative
React Context for cross-component state	Each component has isolated React root	Use nano stores, custom events, or URL params
Prop drilling through Slots	Slot children are separate React apps	Use nano stores or custom events
Shared state via module-level variables	May cause SSR issues	Use browser storage or nano stores
Global event listeners without cleanup	Memory leaks, SSR issues	Use useEffect with cleanup

Refactoring recommendations:

• If components need to communicate → suggest cross-component state pattern
• If using Context internally only → that's fine, document it
• If components are tightly coupled → suggest decomposition

C. Slot Opportunities

Goal: Identify hardcoded content that should be designer-controlled.

Current Pattern	Better Pattern
Hardcoded button inside card	Slot for actions area
Hardcoded icon component	Slot or Image prop
Fixed header/footer structure	Slots for header and footer
Hardcoded list items	Consider if this should be multiple components

When NOT to use Slots:

• When content has specific behavioral requirements
• When content needs to interact with component state
• When the structure is truly fixed and not customizable

D. Shadow DOM Compatibility

Goal: Ensure styles work in isolation.

Issue	Detection	Fix
Using site/global CSS classes	Class names like .container, .btn	Use CSS Modules or component-scoped styles
CSS-in-JS not configured	styled-components/Emotion without decorator	Add globals.ts with styledComponentsShadowDomDecorator (styled-components) or emotionShadowDomDecorator (Emotion/MUI)
Missing style imports	Styles defined but not imported in .webflow.tsx	Add import statement
Relying on inherited styles	Expecting parent styles to cascade	Use explicit styles or CSS variables
Needs tag selectors (h1, p, etc.)	Tags not styled inside Shadow DOM	Enable applyTagSelectors: true in component options

SSR Note: When using styled-components or Emotion, you must also configure the server renderer in webflow.json for SSR to work correctly:

• styled-components: "library": { "renderer": { "server": "@webflow/styled-components-utils/server" } }
• Emotion: "library": { "renderer": { "server": "@webflow/emotion-utils/server" } }

E. SSR Safety

Goal: Identify browser-only code that runs during render.

Pattern	Problem	Solution
window.innerWidth in render	SSR error	Use useEffect or set ssr: false
document.getElementById in render	SSR error	Use useEffect or refs
localStorage.getItem outside useEffect	SSR error	Wrap in useEffect with useState
Third-party library that requires window	SSR error	Dynamic import or ssr: false

F. Component Granularity

Goal: Determine if component is at the right level of abstraction.

Signs a component should be SPLIT:

• Too many props (>10) making Designer UI cluttered
• Multiple distinct sections that could be independent
• Designers want to use parts separately
• Component handles multiple unrelated concerns

Signs components should be COMBINED:

• Always used together
• Tightly coupled state that's awkward to sync
• Small components with no standalone use

Phase 3: Report

Generate actionable report with:

1. Summary: Quick overview of findings
2. By Component: Specific issues and recommendations for each
3. Architecture Recommendations: Cross-cutting concerns
4. Priority Actions: What to fix first

Audit Checklist

Designer Control (Most Important for Webflow)

Check	Question
Prop completeness	Can designers customize everything they'd want to?
Prop types	Are the right Webflow prop types used?
Default values	Do props have sensible defaults?
Prop naming	Are names clear for non-developers?
Slot usage	Is nested content handled via Slots?
Visibility props	Can sections be shown/hidden?

Webflow Compatibility

Check	Question
SSR safe	Does component render without browser APIs?
Style isolation	Do styles work in Shadow DOM?
State independence	Does component work without Context from parent?
No function props	Are there callback props that won't work?

Architecture

Check	Question
Single responsibility	Does component do one thing well?
Right granularity	Is this the right size for Designer use?
Cross-component state	If needed, is it implemented correctly?

Example

User prompt:

Audit my ProductCard component

Response:

## Audit: ProductCard

### Component Overview

```typescript
// Current props
props: {
  title: props.Text(),
  price: props.Number(),
  imageUrl: props.Text()  // ⚠️ Should be Image
}

---

A. Prop Exposure Analysis

Finding	Severity	Recommendation
imageUrl is Text, not Image	Warning	Change to props.Image() for proper asset handling
"Add to Cart" button text is hardcoded	Suggestion	Expose as prop: addToCartText: props.Text()
Sale badge is conditionally rendered but not controllable	Suggestion	Add showSaleBadge: props.Boolean()
Badge color is hardcoded red	Suggestion	Add badgeVariant: props.Variant({ options: ["sale", "new", "featured"] })

Hardcoded Content Found:

// Line 24 - hardcoded, should be prop
<button>Add to Cart</button>

// Line 18 - hardcoded, should be prop or removed
{onSale && <span className="badge">SALE</span>}

Recommended Props to Add:

props: {
  // ...existing
  addToCartLabel: props.Text({
    name: "Button Label",
    defaultValue: "Add to Cart"
  }),
  showBadge: props.Boolean({
    name: "Show Badge",
    defaultValue: false
  }),
  badgeType: props.Variant({
    name: "Badge Type",
    options: ["sale", "new", "featured"],
    defaultValue: "sale"
  })
}

---

B. State Management

Finding	Severity
Uses localStorage for cart count	Warning
No React Context dependencies	OK

Issue: localStorage in render

// Line 8 - will break SSR
const cartCount = localStorage.getItem('cart');

Fix:

const [cartCount, setCartCount] = useState(0);
useEffect(() => {
  setCartCount(parseInt(localStorage.getItem('cart') || '0'));
}, []);

---

C. Slot Opportunities

Current	Recommendation
Hardcoded button	Consider: actions: props.Slot() for flexible CTAs

If designers need to put different content (button, link, custom element) in the action area:

props: {
  actions: props.Slot({
    name: "Actions"
  })
}

// Component
<div className={styles.actions}>
  {actions}
</div>

However, if button behavior is tied to cart logic, keep it hardcoded.

---

D. Shadow DOM Compatibility

Check	Status
Styles imported in .webflow.tsx	✅ OK
CSS Modules used	✅ OK
No global class references	✅ OK

---

E. SSR Safety

Check	Status
window usage	✅ None
document usage	✅ None
localStorage usage	⚠️ Needs guard (see fix above)

---

F. Component Granularity

Current size: 4 props (will be 7 after recommendations) Verdict: Good granularity - single purpose, manageable props

---

Summary

Category	Status
Designer Control	⚠️ Needs work - 4 hardcoded items found
State Management	⚠️ localStorage needs SSR guard
Shadow DOM	✅ Good
SSR Safety	⚠️ One issue
Granularity	✅ Good

Priority Actions:

1. Fix localStorage SSR issue (blocks deployment)
2. Change imageUrl from Text to Image prop
3. Expose badge controls as props
4. Consider exposing button label

## Guidelines

### What This Audit Does NOT Check

This is not a generic code quality audit. Skip:
- Generic React performance patterns (let users use React DevTools)
- Generic accessibility (let users use axe or similar)
- Code formatting (let users use Prettier/ESLint)
- Generic TypeScript best practices

Focus only on Webflow-specific concerns.

### Prop Exposure Heuristics

**Should be a prop:**
- Any text visible in the UI
- Any image or media
- Any color or size that might vary
- Any boolean that controls visibility
- Any value that changes per-use

**Should NOT be a prop:**
- Internal implementation details
- State that changes during interaction
- Values derived from other props
- Animation timing/easing (unless explicitly customizable)

### When to Recommend Slots vs Props

**Use Slot when:**
- Designer wants to put arbitrary Webflow elements inside
- Content structure is flexible
- Nested content doesn't need to interact with component state

**Use Props when:**
- Content is simple (text, image, link)
- Component needs to process/transform the content
- Specific structure is required

### State Pattern Recommendations

If components need to share state, recommend in this order:
1. **URL parameters** - if state should be shareable/bookmarkable
2. **Nano stores** - for real-time sync between components
3. **Custom events** - for fire-and-forget communication
4. **Browser storage** - for persistence across sessions
