I've been testing several React animation libraries and Framer Motion made the highest impression on me. In this post we'll explore how to use Framer Motion to animate Next.js page transitions.
Here's an example:
You can download the source code on GitHub.
What is Framer Motion
Framer Motion is the newest React animation library, a successor to Popmotion Pose. It also powers animations in Framer X, a powerful prototyping tool.
I used Popmotion Pose before, so the concepts behind Framer Motion weren't foreign to me, but I was still amazed by the simple API that makes even complex animations easy to implement.
Framer Motion comes with the server-side rendering support out of the box, so it's also perfect for Next.js apps.
To get started with Framer Motion in a React project, install the framer-motion package from npm:
Note: Framer Motion requires React 16.8 or greater.
9 alternative and related products to Framer Motion. A truly simple production-ready React animation library. Super excited to announce Framer Motion! It's the successor to Pose and is the same simple animation and gesture library that's been powering the Framer Library API. Now production-ready and open source. Framer Motion doesn’t have a page component, so I couldn’t recreate the examples that use it: 14, 15, 16, and 19. And it doesn’t have a scroll component either. But a motion.div can be made draggable, so it’s easy to create a scrollable div that has the same inertia animations as Framer’s component. (Examples 17, 18, 20, and 35).
Hey gang - welcome to your first Frame Motion (for React) tutorial. In this tutorial I'll explain what Framer Motion is and what you'll need to know already. # Animation # Target object. For simple animations, we can set values directly on the animate prop. When any value in animate. Target objects are useful for simple, single-component animations. But sometimes we want to create. # Animation controls. Declarative animations are ideal. Drag and drop with Magic Motion to create an immersive prototype. Just use the connector to draw a link between elements on the canvas. Manipulate size or position and Framer figures out everything else. Draw simple card animations or compose intricate prototypes with data inputs.

Once installed, import
motion
into your components:The core of the Motion API are
motion
components. To animate elements, we need to replace primitive DOM elements (like div
, svg
, etc.) with their Motion counterparts: motion.div
, motion.svg
, etc. These components offer extra props that allow you to declaratively add animations and gestures.motion
components are animated via the animate
prop which can accept an object, variant label(s), or a reference to imperative animation controls.Here's a simple component that animates a single div element:
Using Framer Motion for Next.js page transitions
Framer Motion provides an AnimatePresence component which makes it possible to animate React components as they mount and unmount.
To be able to animate page transitions,
AnimatePresence
must be a direct parent component of individual page components.Fontexplorer x pro 7 0 0 x. In Next.js we can use a special
pages/_app.js
file to create a custom <MyApp>
component where we can include parent components to pages.This is how an _app.js file looks like by default:
The
<Component {..pageProps} />
part represents individual pages, so we can add Framer Motion AnimatePresence
as their parent component like this:Notice that I also added a
key
prop to <Component>
and set it to the current route. This is important so that AnimatePresence
can track the presence of child components in the tree.I also added
exitBeforeEnter
prop to AnimatePresence to make sure the exiting page finishes its exit animation before the next page starts animating.If you need to add a global layout component for your pages, you can do it like this: Infographics maker templates 3 3 2 download free.
I wrote about Next.js layouts in more detail in a previous post.
For the example site, I created two pages, homepage as the 'post index' and a dynamic post page, and defined enter and exit animations for both.
Framer Motion provides Variants, which are sets of pre-defined target objects. They allow us to animate entire sub-trees of components with a single animate prop.
For the post index page I created a parent
motion.div
component with the variants
prop where I defined how the child elements will transition on exit
:With
staggerChildren
we define that children elements (posts) should transition away one by one with animation duration of 0.1 second.To animate individual posts, I wanted a more complex animation, so I defined an object with an initial, enter and exit objects:
Framer Motion
This object is added as variants prop to the post container:
<motion.div variants={postVariants}>
.initial
is used to define starting element styles, enter
for styles to which the element will animate when mounting and exit
for animating when unmounting
.I used the same approach to animate individual posts, but I created separate animations for post image, post text and the back button:
My suggestion is to play with the example code and try adjusting the animations. I hope my examples will help you get started with animating your Next.js apps.
Also check out the Framer Motion docs for more info on all available features.
A key frame (or keyframe) in animation and filmmaking is a drawing or shot that defines the starting and ending points of any smooth transition. These are called frames because their position in time is measured in frames on a strip of film or on a digital video editing timeline. A sequence of key frames defines which movement the viewer will see, whereas the position of the key frames on the film, video, or animation defines the timing of the movement. Because only two or three key frames over the span of a second do not create the illusion of movement, the remaining frames are filled with 'inbetweens'.
Use of key frames as a means to change parameters[edit]
In software packages that support animation, especially 3D graphics, there are many parameters that can be changed for any one object. One example of such an object is a light (In 3D graphics, lights function similarly to real-world lights. They cause illumination, cast shadows, and create specular highlights). Lights have many parameters including light intensity, beam size, light color, and the texture cast by the light. Supposing that an animator wants the beam size to change smoothly from one value to another within a predefined period of time, that could be achieved by using key frames. At the start of the animation, a beam size value is set. Money pro 2 0 1010. Another value is set for the end of the animation. Thus, the software program automatically interpolates the two values, creating a smooth transition.
Video editing[edit]
In non-lineardigital videoediting, as well as in video compositing software, a key frame is a frame used to indicate the beginning or end of a change made to a parameter. For example, a key frame could be set to indicate the point at which audio will have faded up or down to a certain level.
Video compression[edit]
In video compression, a key frame, also known as an 'intra-frame', is a frame in which a complete image is stored in the data stream. In video compression, only changes that occur from one frame to the next are stored in the data stream, in order to greatly reduce the amount of information that must be stored. This technique capitalizes on the fact that most video sources (such as a typical movie) have only small changes in the image from one frame to the next. Whenever a drastic change to the image occurs, such as when switching from one camera shot to another, or at a scene change,[1] a key frame must be created. The entire image for the frame must be output when the visual difference between the two frames is so great that representing the new image incrementally from the previous frame would require more data than recreating the whole image.
Framer Motion Github
Because video compression only stores incremental changes between frames (except for key frames), it is not possible to fast forward or rewind to any arbitrary spot in the video stream. That is because the data for a given frame only represents how that frame was different from the preceding one. For that reason, it is beneficial to include key frames at arbitrary intervals while encoding video. For example, a key frame may be output once for each 10 seconds of video, even though the video image does not change enough visually to warrant the automatic creation of the key frame. That would allow seeking within the video stream at a minimum of 10-second intervals. The down side is that the resulting video stream will be larger in size because many key frames are added when they are not necessary for the frame's visual representation. This drawback, however, does not produce significant compression loss when the bitrate is already set at a high value for better quality (as in the DVDMPEG-2 format).
