description: Create Framer Code Components and Code Overrides. Use when building custom React components for Framer, writing Code Overrides (HOCs) to modify canvas elements, implementing property controls, working with Framer Motion animations, handling WebGL/shaders in Framer, or debugging Framer-specific issues like hydration errors and font handling.

# Framer Code Development
## Code Components vs Code Overrides
**Code Components**: Custom React components added to canvas. Support `addPropertyControls`.
**Code Overrides**: Higher-order components wrapping existing canvas elements. Do NOT support `addPropertyControls`.
## Required Annotations
Always include at minimum:
```typescript
/**
* @framerDisableUnlink
* @framerIntrinsicWidth 100
* @framerIntrinsicHeight 100
*/
```
Full set:
- `@framerDisableUnlink` — Prevents unlinking when modified
- `@framerIntrinsicWidth` / `@framerIntrinsicHeight` — Default dimensions
- `@framerSupportedLayoutWidth` / `@framerSupportedLayoutHeight` — `any`, `auto`, `fixed`, `any-prefer-fixed`
## Code Override Pattern
```typescript
import type { ComponentType } from "react"
import { useState, useEffect } from "react"
/**
* @framerDisableUnlink
*/
export function withFeatureName(Component): ComponentType {
return (props) => {
// State and logic here
return
}
}
```
Naming: Always use `withFeatureName` prefix.
## Code Component Pattern
```typescript
import { motion } from "framer-motion"
import { addPropertyControls, ControlType } from "framer"
/**
* @framerDisableUnlink
* @framerIntrinsicWidth 300
* @framerIntrinsicHeight 200
*/
export default function MyComponent(props) {
const { style } = props
return {/* content */}
}
MyComponent.defaultProps = {
// Always define defaults
}
addPropertyControls(MyComponent, {
// Controls here
})
```
## Critical: Font Handling
**Never access font properties individually. Always spread the entire font object.**
```typescript
// ❌ BROKEN - Will not work
style={{
fontFamily: props.font.fontFamily,
fontSize: props.font.fontSize,
}}
// ✅ CORRECT - Spread entire object
style={{
...props.font,
}}
```
Font control definition:
```typescript
font: {
type: ControlType.Font,
controls: "extended",
defaultValue: {
fontFamily: "Inter",
fontWeight: 500,
fontSize: 16,
lineHeight: "1.5em",
},
}
```
## Critical: Hydration Safety
Framer pre-renders on server. Browser APIs unavailable during SSR.
**Two-phase rendering pattern:**
```typescript
const [isClient, setIsClient] = useState(false)
useEffect(() => {
setIsClient(true)
}, [])
if (!isClient) {
return // SSR-safe fallback
}
// Client-only logic here
```
**Never access directly at render time:**
- `window`, `document`, `navigator`
- `localStorage`, `sessionStorage`
- `window.innerWidth`, `window.innerHeight`
## Critical: Canvas vs Preview Detection
```typescript
import { RenderTarget } from "framer"
const isOnCanvas = RenderTarget.current() === RenderTarget.canvas
// Show debug only in editor
{isOnCanvas && }
```
Use for:
- Debug overlays
- Disabling heavy effects in editor
- Preview toggles
## Property Controls Reference
See [references/property-controls.md](references/property-controls.md) for complete control types and patterns.
## Common Patterns
See [references/patterns.md](references/patterns.md) for implementations: shared state, keyboard detection, show-once logic, scroll effects, magnetic hover, animation triggers.
## Variant Control in Overrides
Cannot read variant names from props (may be hashed). Manage internally:
```typescript
export function withVariantControl(Component): ComponentType {
return (props) => {
const [currentVariant, setCurrentVariant] = useState("variant-1")
// Logic to change variant
setCurrentVariant("variant-2")
return
}
}
```
## Scroll Detection Constraint
Framer's scroll detection uses viewport-based IntersectionObserver. Applying `overflow: scroll` to containers breaks this detection.
For scroll-triggered animations, use:
```typescript
const observer = new IntersectionObserver(
(entries) => {
entries.forEach((entry) => {
if (entry.isIntersecting && !hasEntered) {
setHasEntered(true)
}
})
},
{ threshold: 0.1 }
)
```
## WebGL in Framer
See [references/webgl-shaders.md](references/webgl-shaders.md) for shader implementation patterns including transparency handling.
## NPM Package Imports
Standard import (preferred):
```typescript
import { Component } from "package-name"
```
Force specific version via CDN when Framer cache is stuck:
```typescript
import { Component } from "https://esm.sh/package-name@1.2.3?external=react,react-dom"
```
Always include `?external=react,react-dom` for React components.
## Common Pitfalls
| Issue | Cause | Fix |
|-------|-------|-----|
| Font styles not applying | Accessing font props individually | Spread entire font object: `...props.font` |
| Hydration mismatch | Browser API in render | Use `isClient` state pattern |
| Override props undefined | Expecting property controls | Overrides don't support `addPropertyControls` |
| Scroll animation broken | `overflow: scroll` on container | Use IntersectionObserver on viewport |
| Shader attach error | Null shader from compilation failure | Check `createShader()` return before `attachShader()` |
| Component display name | Need custom name in Framer UI | `Component.displayName = "Name"` |
## Mobile Optimization
For particle systems and heavy animations:
- Implement resize debouncing (500ms default)
- Add size change threshold (15% minimum)
- Handle orientation changes with dedicated listener
- Use `touchAction: "none"` to prevent scroll interference
## CMS Content Timing
CMS content loads asynchronously after hydration. Processing sequence:
1. SSR: Placeholder content
2. Hydration: React attaches
3. CMS Load: Real content (~50-200ms)
Add delay before processing CMS data:
```typescript
useEffect(() => {
if (isClient && props.children) {
const timer = setTimeout(() => {
processContent(props.children)
}, 100)
return () => clearTimeout(timer)
}
}, [isClient, props.children])
```
## Text Manipulation in Overrides
Framer text uses deeply nested structure. Process recursively:
```typescript
const processChildren = (children) => {
if (typeof children === "string") {
return processText(children)
}
if (isValidElement(children)) {
return cloneElement(children, {
...children.props,
children: processChildren(children.props.children)
})
}
if (Array.isArray(children)) {
return children.map(child => processChildren(child))
}
return children
}
```
## Animation Best Practices
**Separate positioning from animation:**
```typescript
```
**Split animation phases for natural motion:**
```typescript
// Up: snappy pop
transition={{ duration: 0.15, ease: [0, 0, 0.39, 2.99] }}
// Down: smooth settle
transition={{ duration: 0.15, ease: [0.25, 0.46, 0.45, 0.94] }}
```
## Safari SVG Fix
Force GPU acceleration for smooth SVG animations:
```typescript
style={{
willChange: "transform",
transform: "translateZ(0)",
backfaceVisibility: "hidden",
}}
```
