![]() ![]() ![]() I've seem to remember strange experiences with nested s. Haven't gotten to try it yet, because I am concerned this may cause side effects I'm not aware of and will then have to painfully discover. I thought to try that last night when I posted. Try to wrap the desired child subtree with Lots of people are probably depending on this and are unaware of it, even. Regarding your comment before you edited (that any changes to this behavior would be breaking) and how you write now: (which, however, does not work with controls, so maybe that's an issue here too). These changes in variant will flow down until a child component defines its own animate property. After that, initial effects should still work, at least for motion components controlled by Animation Controls, where settings initial state seems to be required for animating later anyway. Initial= from AnimatePresence should apply only up to the depth of the first descendants that are encountered with an exit prop. Notice how the variant on line 18 is not applied on first render. IMPORTANT: Provide a CodeSandbox reproduction of the bug After struggling for a long time to figure out why this initial state was not rendering, I finally figured out it was due to an AnimatePresence way, way higher up in the render tree, responsible for animating route transitions.ģ. In my case, I was trying to use initial to set initial state for animation controls. The result is that at any arbitrary depth below an, initial motion state is suppressed. I overcame some obstacles when adding them to my website such as realising AnimatePresence needed to be in _app.js and how to stop the scroll to the top of the page after a Link is clicked.Suppresses initial state for all motion components below it in the render tree, not just descendants with exit props. In this article I wanted to help others add page transitions to their Next.js app with the help of Framer Motion. ![]() If you've been following along or want to see it live on my website you'll see the following page transitions: The finished page animation Having added that, when you change page Framer Motion should unmount the old content, scroll to the top and mount the new content. You can read more about them on the Framer Motion website. Variants promote cleaner code by removing the requirement to add the animation object to the motion.main component. Looking at the Layout component you will see an object named variants (see below). supplied by Framer Motion provides the ability to pass certain animation props such as transition, initial and animate. In the rendered HTML output this will be a HTML main element, however, adding the motion. Note the component which is specific to Framer Motion. On my website it is the Layout component. In my case this meant moving the Header and Footer which you can see on GitHub.Īdded a wrapper component to control the animation states within pages. Moved common components that shouldn't animate on every page change into _app.js. Preparing the codebaseīefore I added any animations to my website I did two pieces of refactoring: Where possible, using _app.js to persist layouts between page changes will reduce the amount of rendering that React has to do each time the page changes - potentially improving your app performance. In Next.js terms, this is everything apart from _app.js - so all pages and other components. I use this capability to animate the components that come and go when the page changes.
