React Animate Presence: Seamless Exit and Enter Component Transitions
React Animate Presence solves one of the most frustrating challenges in modern frontend engineering: animating components as they unmount from the DOM. By default, React immediately destroys elements when conditional state toggles to false, causing abrupt visual cuts and preventing smooth exit transitions. With ExodeUI, Animate Presence is powered by hardware-accelerated state machines that defer component destruction until your physics-driven exit animation completes. This guarantees flicker-free modals, sliding toast notifications, and multi-step flow transitions without race conditions or complex layout shift glitches.
Runnable ExodeUI React Code Example
Production ReadyImport the ExodeUICanvas component directly into your React application tree. Wire states, triggers, and parameters declaratively:
import React, { useState } from 'react';
import { ExodeUICanvas } from 'exodeui';
export function DismissibleCard() {
const [isVisible, setIsVisible] = useState(true);
return (
<div className="card-container">
{isVisible && (
<ExodeUICanvas
src="/scenes/dismiss-card.json"
stateMachine="CardPresence"
inputs={{ "isActive": isVisible }}
onStateChange={(state) => {
if (state === 'exitComplete') {
console.log('Component safely unmounted from layout');
}
}}
/>
)}
<button onClick={() => setIsVisible(!isVisible)}>
{isVisible ? 'Dismiss Card' : 'Restore Card'}
</button>
</div>
);
}Frequently Asked Questions about react animate presence
How does React Animate Presence prevent layout shifts on exit?
ExodeUI utilizes hardware-accelerated FLIP bounding math and state machines to freeze the unmounting node geometry until the exit velocity reaches zero, seamlessly collapsing layout space without abrupt visual jumps.
How does ExodeUI Animate Presence compare to Framer Motion?
While Framer Motion requires wrapping elements in an AnimatePresence component and tracking child keys, ExodeUI uses native state machine events compiled directly into React JSX, reducing JS thread overhead.
Can ExodeUI Animate Presence handle simultaneous enter and exit?
Yes. ExodeUI supports concurrent enter and exit modes (including wait, sync, and popLayout modes) controlled visually in the MDE without manual timing calculations.
