What we’re building
I’ll help you start adding more delight to your Next.js app (or other React apps) with transitions between pages. We’re going to use the AnimateSharedLayout component from the Framer Motion API to make pages blend between each other seamlessly.
Why?
The web is a powerful platform that has a lot to offer. By adding seamless transitions between webpages, we begin to shift towards a more native feeling UI which delights user’s and brings your website or web app into a class of its own.
Why Next.js?
Next.js is a popular framework for building web apps and for good reason. It builds upon React to offer a great developer experience. One of the most obvious features we’re leveraging is the built in routing. We’re going to build our transitions upon what’s already built in to Next. If you’d like to apply this technique to an existing project, it should be easy to do so.
Why Framer Motion?
Framer motion is an easy-to-use library which can achieve our desired transition effect quickly and is powerful. It gives us the ability to mix a variety of different animation types and can be a good foundation for making your pages even more delightful for users. When combined with Next.js, it offers a rich user experience and developer experience that I love.
What we need to start animating
The two key ingredients are Next.js and Framer Motion. If you’re not using Next.js and instead are using another React router library, you’ll still get and idea of how this could fit in. It’s not exclusive to Next.js or Framer Motion, these are just two of my favourites that work well together. Feel free to mix and match.
About the project
The project contains two pages which we will animate between. The elements that are not shared between pages will animate in while the elements that are shared will animate between pages instead.

Identify the elements that stay the same
For our example we’re going to animate between two pages. The first page is a simple landing page with an image, a title, a paragraph and a button. Clicking on the button will navigate to our other page. A features page with the same title and image but it’s surrounded but other icons and feature descriptions.
We can’t transition between all of these elements because they aren’t all on both pages. The title and image are the same so these are the most obvious candidates. The button looks like it could work but the text content differs, it’s possible with a bit of work to create something that looks passable but I’ll skip the layout transition for this element.
Adding the AnimateSharedLayout to _app
The first step is to set and forget our AnimateSharedLayout component. The component enables us to animate layout changes between different components and tell Framer which elements are shared and therefore should transition to the new state. To set this up, inside _app we’ll import it:
import { AnimateSharedLayout } from "framer-motion"; then wrap our Component.
Our _app looks like this. I’m using the Bulma CSS library and SASS along with FontAwesome icons. The Component prop in the context of MyApp is the whatever page we are currently on. In Next.js, this acts as a layout which is used across our pages. It’s especially useful for our purposes because we want to be able to animate seamlessly between all the pages in our app.
import "../styles/theme.sass"
import "@fortawesome/fontawesome-free/css/all.css"
import { AnimateSharedLayout } from "framer-motion"
function MyApp({ Component, pageProps }) {
return (
<AnimateSharedLayout>
<Component {...pageProps} />
</AnimateSharedLayout>
)
}
export default MyApp
We’ve added AnimateSharedLayout but nothing has changed, let’s turn our title and image elements into motion components.
Using layoutId to setup the transitions
On our first page, index.js, let’s import the motion component from framer-motion, import { motion } from "framer-motion";. This component allows us to turn normal html elements into animatable components. Usually, we’d add the animate prop, so we can define the animation but the only thing we need for the transition is the layoutId prop. It’s a string which will be unique across our app.
Our title will go from this:
<h1 className="title has-text-weight-bold is-1 is-size-2-mobile is-spaced">
The only Todo App you'll ever need
</h1>
To this:
<motion.h1
className="title has-text-weight-bold is-1 is-size-2-mobile is-spaced"
layoutId="title"
>
The only Todo App you'll ever need
</motion.h1>
We’ll do the same with the figure element that wraps our image.
<motion.figure className="image" layoutId="image">
<Image src="/assets/task.png" layout="responsive" width={780} height={501} />
</motion.figure>
Let’s replace the matching elements on our features.js page too. When the page transitions from / to /features, framer will treat the elements on one page with the elements on the second page as the same if they share an identical layoutId.
Try it out, and we’ll see the title and image moves smoothly across the screen.
Completing the look with motion
The approach is very cool because it allows us to go forward and back between pages and the transition works as expected. This is a good starting point, and we’ve achieved the core effect but I think it needs a bit more. Let’s finish the look off by utilising Framer Motion to add an intro animation to elements that aren’t shared across pages.
For elements that are unique to a page, we’ll fade them in.
Here’s an example of the subtitle on the index page:
<motion.p
className="subtitle"
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
transition={{ delay: 0.2 }}
>
This is a straightforward fade in animation that starts with an opacity of zero and animates to an opacity of 1 after a delay of 200ms.
But what happens when the user first visits a page? Can we animate all elements in? With Framer Motion, yes we can. We can add the animate prop to have an intro animation that will play when the user opens the page and this won’t affect the transition to the next page.
Here’s our animation, a fade in with a slight scale up effect
<motion.h1
initial={{ scale: 0.8, opacity: 0 }}
animate={{ scale: 1, opacity: 1 }}
className="title has-text-weight-bold is-1 is-size-2-mobile is-spaced"
layoutId="title"
>
Let’s see the final product:
Where to now?
We’ve created some cool effects that really breath life into the app with pretty minimal effort for the developer. Framer Motion allows us to create these complex layout animations easily and without compromise. It’s easy to tweak how pages animate in or out as well as the transition between pages. I hope you’ve learned something new and will apply some of these techniques to your projects.
The web is a platform that can do so much more than static webpages. As a platform for rich user experience, we have the opportunity to craft more imaginative user interfaces that really react to the user’s actions and exceed expectations. Animation through page transitions is one of the tools we have available to enrich experiences, and they’re easy with Next.js and Framer Motion.
