Learn how Framer Motion's layout prop and layoutId create smooth DOM reordering and shared element transitions using the FLIP technique.
When a component tree undergoes a schema change—such as adding, removing, or reordering elements that are animated with Framer Motion—there is a risk that exit animations may be interrupted or that the rollback leaves the UI in an inconsistent state. Using `animatePresence` allows components to animate out before unmounting, but ensuring that the rollback pr
Framer Motion's animation primitives depend on browser APIs, so inside the Next.js App Router they must sit behind a client boundary marked with use client . A small React application can therefore adopt motion.* components piece by piece while unconverted routes keep their existing CSS transitions. The interoperability question is what happens at the seam.
Goal: Verify whether Framer Motion's AnimatePresence component triggers its exit animations when a Next.js App Router route is unmounted via navigation. Constraint: AnimatePresence only animates children that it directly removes by tracking their key props, while the App Router removes route segments through its internal router rather than a React state chan
Shared Layout Animations and Mount Timing Framer Motion uses the layoutId prop to coordinate shared element transitions between different components. For this mechanism to function, the library requires both the exiting component and the entering component to be mounted in the DOM during the same render pass to calculate the transition delta. Router Integrat
Goal What is the correct pattern for ensuring AnimatePresence exit animations complete before DOM removal when a parent component unmounts the AnimatePresence wrapper during rapid mount/unmount cycles? Constraint AnimatePresence only waits for exit animations while the child remains mounted in React's tree. If an ancestor unmounts the wrapper, React may batc
Integration boundary Framer Motion's AnimatePresence wrapper coordinates with React's rendering lifecycle to run exit animations when children are removed from the tree. The integration point is the moment React commits the unmount— AnimatePresence must keep the DOM node alive until the exit animation finishes, yet React expects the component to disappear sy
Goal When a list item that uses a layoutId is removed from the DOM via animatePresence and then re‑inserted with the same layoutId after a short delay, we want the exit animation to finish cleanly without being interrupted by a new enter animation, so the UI shows a smooth fade‑out followed by a fade‑in. Constraints and uncertainty The exact timing of the ex
Context When using AnimatePresence with the layout prop on list items, the mode prop controls whether remaining siblings animate layout changes immediately or wait for exiting nodes. The documentation describes popLayout and sync as common settings, but the exact timing of layout measurements relative to exit animation completion is not explicitly specified.
