| 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:
Full set:
@framerDisableUnlink — Prevents unlinking when modified
@framerIntrinsicWidth / @framerIntrinsicHeight — Default dimensions
@framerSupportedLayoutWidth / @framerSupportedLayoutHeight — any, auto, fixed, any-prefer-fixed
Code Override Pattern
import type { ComponentType } from "react"
import { useState, useEffect } from "react"
export function withFeatureName(Component): ComponentType {
return (props) => {
return <Component {...props} />
}
}
Naming: Always use withFeatureName prefix.
Code Component Pattern
import { motion } from "framer-motion"
import { addPropertyControls, ControlType } from "framer"
export default function MyComponent(props) {
const { style } = props
return <motion.div style={{ ...style }}>{/* content */}</motion.div>
}
MyComponent.defaultProps = {
}
addPropertyControls(MyComponent, {
})
Critical: Font Handling
Never access font properties individually. Always spread the entire font object.
style={{
fontFamily: props.font.fontFamily,
fontSize: props.font.fontSize,
}}
style={{
...props.font,
}}
Font control definition:
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:
const [isClient, setIsClient] = useState(false)
useEffect(() => {
setIsClient(true)
}, [])
if (!isClient) {
return <Component {...props} />
}
Never access directly at render time:
window, document, navigator
localStorage, sessionStorage
window.innerWidth, window.innerHeight
Critical: Canvas vs Preview Detection
import { RenderTarget } from "framer"
const isOnCanvas = RenderTarget.current() === RenderTarget.canvas
{isOnCanvas && <DebugOverlay />}
Use for:
- Debug overlays
- Disabling heavy effects in editor
- Preview toggles
Property Controls Reference
See references/property-controls.md for complete control types and patterns.
Common Patterns
See 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:
export function withVariantControl(Component): ComponentType {
return (props) => {
const [currentVariant, setCurrentVariant] = useState("variant-1")
setCurrentVariant("variant-2")
return <Component {...props} variant={currentVariant} />
}
}
Scroll Detection Constraint
Framer's scroll detection uses viewport-based IntersectionObserver. Applying overflow: scroll to containers breaks this detection.
For scroll-triggered animations, use:
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 for shader implementation patterns including transparency handling.
NPM Package Imports
Standard import (preferred):
import { Component } from "package-name"
Force specific version via CDN when Framer cache is stuck:
import { Component } from "https://esm.sh/package-name@1.2.3?external=react,react-dom"
Always include ?external=react,react-dom for React components.
HLS Video Streaming (.m3u8)
Chrome/Firefox do not natively support HLS streams. A plain <video src="...m3u8"> will either fail or play the lowest quality rendition permanently. Safari handles HLS natively.
Fix: Use HLS.js via dynamic import with silent fallback:
let HlsModule = null
let hlsImportAttempted = false
async function loadHls() {
if (hlsImportAttempted) return HlsModule
hlsImportAttempted = true
try {
const mod = await import("https://esm.sh/hls.js@1?external=react,react-dom")
HlsModule = mod.default || mod
} catch {
HlsModule = null
}
return HlsModule
}
function attachHls(videoEl, src) {
if (typeof window === "undefined") return null
const Hls = HlsModule
if (src.includes(".m3u8") && Hls?.isSupported()) {
const hls = new Hls({ startLevel: -1, capLevelToPlayerSize: true })
hls.loadSource(src)
hls.attachMedia(videoEl)
hls.on(Hls.Events.MANIFEST_PARSED, () => videoEl.play().catch(() => {}))
hls.on(Hls.Events.ERROR, (_, data) => {
if (data.fatal) {
data.type === Hls.ErrorTypes.NETWORK_ERROR
? hls.startLoad()
: hls.destroy()
}
})
return hls
}
videoEl.src = src
videoEl.play().catch(() => {})
return null
}
Key points:
- Dynamic import avoids breaking the component if CDN is unreachable
capLevelToPlayerSize: true prevents loading 4K for a 400px player
- Must destroy HLS instances on cleanup to prevent memory leaks
- Use
cancelled flag in effects to prevent stale attachment after fast navigation
- Works on Framer canvas and published site
Common Pitfalls
| Issue | Cause | Fix |
|---|
| Variable text not found in override | Reading only props.children | Check props.text first — variable-bound text bypasses children |
| 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" |
TypeScript Timeout errors | Using NodeJS.Timeout type | Use number instead — browser environment |
| Overlay stuck under content | Stacking context from parent | Use React Portal to render at document.body level |
| Easing feels same for all curves | Not tracking initial distance | Track initialDiff when target changes for progress calculation |
| HLS video permanently pixelated | .m3u8 in Chrome without HLS.js | Use HLS.js dynamic import pattern (see HLS section above) |
| Overlay stuck "half-pressed" / needs two clicks to close | Triggering Framer interactions with synthetic events (dispatchEvent) | Call the React handler directly via fiber traversal (see "Triggering Framer-Attached Handlers") |
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 text arrives in props.text asynchronously (~50–200ms after hydration). For variable-bound text from component props, it's synchronous on first render — no delay needed.
The reliable pattern for both: use resolvePlainText(props) (see Text in Overrides) and gate on the value being non-empty:
const plainText = resolvePlainText(props)
Avoid 100ms arbitrary delays — they cause race conditions when the element is already in the viewport on load.
Text in Overrides
Text comes from two different sources depending on how it's set:
| Source | Where it lives | When |
|---|
| Static text (typed in Framer) | props.children nested structure | Always available on first render |
| Variable-bound text (component prop / CMS) | props.text (plain string) | Available on first render for variables; async for CMS |
Always check props.text first, fall back to children:
import { isValidElement } from "react"
function extractParts(raw: any): any[] {
if (typeof raw === "string") return [raw]
if (isValidElement(raw)) return [raw]
if (Array.isArray(raw)) return raw.flatMap(extractParts)
return []
}
function toPlainText(parts: any[]): string {
return parts.map((p) => (typeof p === "string" ? p : "\n")).join("")
}
function resolvePlainText(props: any): string {
if (typeof props.text === "string" && props.text.length > 0) {
return props.text
}
const raw = props.children?.props?.children?.props?.children
return toPlainText(extractParts(raw))
}
Never assume text is only in props.children. Variable-bound text bypasses the children structure entirely — props.children will contain a placeholder while props.text has the real value. If you only read children, variable text is invisible to your override.
Triggering Framer-Attached Handlers from Code
When you need to programmatically fire a Framer/Framer Motion interaction (open an overlay, trigger a tap, etc.), synthetic DOM events do not work reliably. Framer Motion attaches handlers like onTap as React handlers, not native DOM listeners — synthetic events take a different code path and leave Framer Motion's internal state desynchronised. Symptoms include stuck press/focus state, two-click-to-close bugs, and other "half-pressed" weirdness that persists for the rest of the session on that element.
Reach into the React fiber tree and call the handler directly:
function findFiberHandler(el: HTMLElement, name: string): unknown {
const key = Object.keys(el).find((k) => k.startsWith("__reactFiber"))
if (!key) return undefined
let fiber: any = (el as any)[key]
let depth = 0
while (fiber && depth < 15) {
const p = fiber.memoizedProps
if (p && typeof p[name] === "function") return p[name]
fiber = fiber.return
depth++
}
return undefined
}
const onTap = findFiberHandler(wrapper, "onTap")
onTap?.({} as any, {} as any)
Why walk fiber.return: Framer wraps interactive elements in Framer Motion components several fiber levels above the rendered DOM node. The DOM wrapper does not carry onTap in its own props — you have to walk up to find it. In practice the handler lives ~2 levels up; 15 is a safe ceiling.
In Framer, overlay triggers render as DOM nodes with tabindex="0" and an id, so el.closest("[tabindex]") is a reliable way to find the wrapper from a child override.
Use case: URL deep link to an overlay
Apply an override to a CMS text field bound to a per-item slug. On mount, match the URL param against props.text, walk up to the nearest [tabindex] wrapper, find onTap, invoke it, then clean the URL:
import type { ComponentType } from "react"
import { useEffect, useRef } from "react"
export function withMemberDeepLink(Component): ComponentType {
return (props) => {
const ref = useRef<HTMLElement | null>(null)
const done = useRef(false)
useEffect(() => {
if (done.current || typeof window === "undefined") return
const target = new URLSearchParams(window.location.search).get("member")
if (!target || target !== (props.text || "").trim()) return
const t = setTimeout(() => {
const wrapper = ref.current?.closest("[tabindex]") as HTMLElement | null
if (!wrapper) return
const onTap = findFiberHandler(wrapper, "onTap")
if (typeof onTap !== "function") return
onTap({} as any, {} as any)
const url = new URL(window.location.href)
url.searchParams.delete("member")
window.history.replaceState({}, "", url.toString())
done.current = true
}, 500)
return () => clearTimeout(t)
}, [props.text])
return (
<span ref={ref} style={{ display: "contents" }}>
<Component {...props} />
</span>
)
}
}
The 500ms timeout here is waiting for Framer's overlay wrapper to mount, not for CMS content — different concern from the CMS Content Timing section above.
Debugging React internals
Inspect props on an element:
const el = document.getElementById("YOUR_ID")
const key = Object.keys(el).find(k => k.startsWith("__reactProps"))
console.log(el[key])
Find all handler functions up the fiber tree (useful when you don't yet know what Framer attached or at which depth):
const el = document.getElementById("YOUR_ID")
const fiberKey = Object.keys(el).find(k => k.startsWith("__reactFiber"))
let fiber = el[fiberKey]
for (let depth = 0; fiber && depth < 15; depth++, fiber = fiber.return) {
const mp = fiber.memoizedProps
if (!mp) continue
const fns = Object.keys(mp).filter(k => typeof mp[k] === "function")
if (fns.length) console.log(`Depth ${depth}:`, fns)
}
Maintenance risks
__reactFiber$... / __reactProps$... are React internals. The $<suffix> changes between React builds; the prefixes have been stable for years but are not officially supported API.
- Framer Motion handler names (
onTap etc.) could change with future Framer updates.
- Fiber depth to reach the handler is project-dependent — 15 is a safe ceiling but may need to grow if Framer restructures wrappers.
Animation Best Practices
Separate positioning from animation:
<motion.div
style={{
position: "absolute",
left: `${offset}px`,
x: animatedValue,
}}
/>
Split animation phases for natural motion:
transition={{ duration: 0.15, ease: [0, 0, 0.39, 2.99] }}
transition={{ duration: 0.15, ease: [0.25, 0.46, 0.45, 0.94] }}
Safari SVG Fix
Force GPU acceleration for smooth SVG animations:
style={{
willChange: "transform",
transform: "translateZ(0)",
backfaceVisibility: "hidden",
}}
Z-Index Stacking Context & React Portals
Problem: Components with position: absolute inherit their parent's stacking context. Even with z-index: 9999, they can't appear above elements outside the parent.
Solution: Use React Portal to render at document.body level:
import { createPortal } from "react-dom"
export default function ComponentWithOverlay(props) {
const [showOverlay, setShowOverlay] = useState(false)
return (
<div style={{ position: "relative" }}>
{/* Main component content */}
{/* Overlay rendered outside parent hierarchy */}
{showOverlay && createPortal(
<div style={{
position: "fixed", // Fixed to viewport
inset: 0,
zIndex: 9999,
background: "rgba(0, 0, 0, 0.8)",
}}>
{/* Overlay content */}
</div>,
document.body
)}
</div>
)
}
Key differences:
position: "fixed" positions relative to viewport, not parent
- Portal breaks out of component's DOM hierarchy and stacking context
- Works for modals, tooltips, popovers, loading overlays
Canvas vs Published:
Portals work in both canvas editor and published site. No RenderTarget check needed.
Loading States with Scroll Lock
Pattern: Show loading overlay and prevent page scroll until content is ready.
const [isLoading, setIsLoading] = useState(true)
const [fadeOut, setFadeOut] = useState(false)
useEffect(() => {
const isPublished = RenderTarget.current() !== "CANVAS"
if (!isPublished || !isLoading) return
const originalOverflow = document.body.style.overflow
document.body.style.overflow = "hidden"
return () => {
document.body.style.overflow = originalOverflow
}
}, [isLoading])
const hideLoader = () => {
setFadeOut(true)
setTimeout(() => setIsLoading(false), 300)
}
Scroll to top on load (fixes variant sequence issues):
useEffect(() => {
const isPublished = RenderTarget.current() !== "CANVAS"
if (isPublished) {
window.scrollTo(0, 0)
}
}, [])
Easing Curves with Lerp Animations
Problem: Exponential lerp (value += diff * speed) naturally gives ease-out. Need to track initial distance to implement other curves.
Solution: Track initialDiff when animation starts:
const animated = useRef({
property: {
current: 0,
target: 0,
initialDiff: 0,
}
})
const updateTarget = (newTarget) => {
const entry = animated.current.property
entry.initialDiff = Math.abs(newTarget - entry.current)
entry.target = newTarget
}
const applyEasing = (easingCurve) => {
const v = animated.current.property
const diff = v.target - v.current
let speed = 0.05
if (easingCurve !== "ease-out") {
const diffMagnitude = Math.abs(diff)
const progress = v.initialDiff > 0
? Math.max(0, Math.min(1, 1 - (diffMagnitude / v.initialDiff)))
: 1
if (easingCurve === "ease-in") {
speed *= (0.05 + Math.pow(progress, 3) * 10)
} else if (easingCurve === "ease-in-out") {
const smoothed = progress * progress * progress *
(progress * (progress * 6 - 15) + 10)
speed *= (0.2 + smoothed * 3)
}
}
v.current += diff * speed
}
Why aggressive curves?
Exponential lerp naturally slows down approaching target. To create noticeable ease-in, need extreme multipliers (0.05x → 10x) to overcome the natural decay.
Property control:
easingCurve: {
type: ControlType.Enum,
title: "Easing Curve",
options: ["ease-out", "ease-in", "ease-in-out"],
optionTitles: ["Ease Out", "Ease In", "Ease In/Out"],
defaultValue: "ease-out",
}
