Framer Code Components & Overrides

Overview

Build code components with property controls and code overrides for Framer sites. Components are custom React rendered on the canvas. Overrides modify existing layer behavior (animations, interactions) without changing the component.

Prerequisites

• Framer project open in editor
• Understanding of React and Framer Motion

Instructions

Step 1: Code Component with Property Controls

import { addPropertyControls, ControlType } from 'framer';
import { useRef, useEffect, useState } from 'react';

interface Props { target: number; duration: number; suffix: string; fontSize: number; color: string; }

export default function AnimatedCounter({ target = 1000, duration = 2, suffix = '+', fontSize = 48, color = '#000' }: Props) {
  const ref = useRef(null);
  const [count, setCount] = useState(0);
  const [started, setStarted] = useState(false);

  useEffect(() => {
    const observer = new IntersectionObserver(([e]) => { if (e.isIntersecting) setStarted(true); }, { threshold: 0.5 });
    if (ref.current) observer.observe(ref.current);
    return () => observer.disconnect();
  }, []);

  useEffect(() => {
    if (!started) return;
    const inc = target / (duration * 60);
    let val = 0;
    const timer = setInterval(() => {
      val += inc;
      if (val >= target) { setCount(target); clearInterval(timer); }
      else setCount(Math.floor(val));
    }, 1000 / 60);
    return () => clearInterval(timer);
  }, [started, target, duration]);

  return <div ref={ref} style={{ fontSize, fontWeight: 700, color, textAlign: 'center' }}>{count.toLocaleString()}{suffix}</div>;
}

addPropertyControls(AnimatedCounter, {
  target: { type: ControlType.Number, title: 'Target', defaultValue: 1000 },
  duration: { type: ControlType.Number, title: 'Duration (s)', defaultValue: 2 },
  suffix: { type: ControlType.String, title: 'Suffix', defaultValue: '+' },
  fontSize: { type: ControlType.Number, title: 'Font Size', defaultValue: 48 },
  color: { type: ControlType.Color, title: 'Color', defaultValue: '#000' },
});

Step 2: Data-Fetching Component

import { addPropertyControls, ControlType } from 'framer';
import { useEffect, useState } from 'react';

export default function DataList({ apiUrl = 'https://jsonplaceholder.typicode.com/posts', limit = 5 }) {
  const [items, setItems] = useState<any[]>([]);
  useEffect(() => {
    fetch(apiUrl).then(r => r.json()).then(d => setItems(d.slice(0, limit))).catch(() => {});
  }, [apiUrl, limit]);
  return (
    <ul style={{ listStyle: 'none', padding: 0 }}>
      {items.map((item, i) => <li key={i} style={{ padding: '8px 0', borderBottom: '1px solid #eee' }}>{item.title || item.name}</li>)}
    </ul>
  );
}

addPropertyControls(DataList, {
  apiUrl: { type: ControlType.String, title: 'API URL', defaultValue: 'https://jsonplaceholder.typicode.com/posts' },
  limit: { type: ControlType.Number, title: 'Limit', defaultValue: 5 },
});

Step 3: Code Overrides

// overrides.tsx — apply to any layer via properties panel
import { Override } from 'framer';

export function FadeInOnScroll(): Override {
  return { initial: { opacity: 0, y: 20 }, whileInView: { opacity: 1, y: 0 }, transition: { duration: 0.6 }, viewport: { once: true } };
}

export function MagneticHover(): Override {
  return { whileHover: { scale: 1.05 }, whileTap: { scale: 0.95 }, transition: { type: 'spring', stiffness: 400, damping: 17 } };
}

export function TypewriterText(): Override {
  return {
    initial: { width: 0 },
    animate: { width: '100%' },
    transition: { duration: 2, ease: 'linear' },
    style: { overflow: 'hidden', whiteSpace: 'nowrap' },
  };
}

Step 4: Plugin Creating Code Files

import { framer } from 'framer-plugin';

async function createOverrideFile() {
  const codeFile = await framer.createCodeFile({ name: 'Animations', language: 'tsx' });
  await codeFile.setFileContent(`
import { Override } from 'framer';
export function FadeIn(): Override {
  return { initial: { opacity: 0 }, animate: { opacity: 1 }, transition: { duration: 0.8 } };
}`.trim());
  framer.notify('Override file created');
}

Output

• Animated components with property controls
• Data-fetching components for external APIs
• Reusable code overrides for animations
• Programmatic code file creation

Error Handling

Error	Cause	Solution
Component blank	Runtime error	Check Framer browser console
Controls not showing	Missing addPropertyControls	Call after component export
Override not applying	Wrong export	Must return Override type
Fetch fails	CORS	Use CORS-enabled API
