Framer Motion React Animations

Introduction

Modern web development relies heavily on animations to create a dynamic and interesting user experience. Creating animations in React applications can be done using traditional CSS or JavaScript however, it can become very cumbersome. Various libraries like GSAP, React Spring, anime.js, etc were created to combat the ambiguity in creating animations but one worthy to note is Framer Motion. Framer Motion is a famous React animation library that makes constructing complicated animations easier by providing utility animation components as well as hooks. In this article, we will walk you through the features and functionalities of Framer Motion.

What is Framer motion?

Framer-motion is an open-source React animation and gesture library that offers a low-level API for integrating animation and gestures into elements in React applications while preserving HTML and SVG semantics.

Framer-motion was made by Framer, the company behind the Framer site builder designed for creative professionals.

Setting up Framer Motion in React.

To setup framer motion in a React project, you must install the framer motion package using the below commands

npm

npm install framer-motion

Components in Framer

Framer Motion includes a set of key components that serve as the basis for producing animations They are:

Motion

The motion component encapsulates HTML elements in React components, allowing you to animate them using initial and animate props. Motion components are DOM primitives designed specifically for 60fps animation and gestures.

Props available in motion components

  • animate:

    The animate prop is in responsible for animating motion components because it holds the CSS properties to be animated. It is an object that accepts a key-value pair representing the CSS property(in camel case) and its value, respectively.

An example of the animate prop on a motion component is provided below:

<motion.div
animate={{
x: 0,
backgroundColor: "#000",
boxShadow: "10px 10px 0 rgba(0, 0, 0, 0.2)",
position: "fixed",
}}
/>

in the example above, the properties backgroundColor, boxShadow, position are animated to their respective specified values.

Examples of text and image animations using motion animate props
  • animating texts using its opacity

Code:

<motion.p
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
className="text-[40px] font-bold capitalize"
>
Text animated using opacity
</motion.p>

From the code above, we can specify the initial animation property and value to be animated using the initial props and then animate that to another value using the animate props.

  • Animating texts using its transform scale:

Code:

<motion.p
initial={{ scale: 0.5 }}
animate={{ scale: 1 }}
className="text-[40px] font-bold capitalize"
>
Text animated using scale
</motion.p>

View:

typescript zod
  • Animating texts using their opacity and scale: you can also combine properties to get the desired animation.

Code:

<motion.p
initial={{ opacity: 0, scale: 0.5 }}
animate={{ opacity: 1, scale: 1 }}
className="text-[40px] font-bold capitalize"
>
Text animated using opacity and scale
</motion.p>

View:

typescript zod
  • Animating texts with translate transforms: We can create a translate animation by defining the x and y positions.

Code:

<motion.p
initial={{ x: -100, y: -100 }}
animate={{ x: 1, y: 1 }}
className="text-[30px] font-bold capitalize"
>
Text animated using transform translate
</motion.p>

  • layout

    The layout props is effective in animating layouts (like height width, flex properties like justify-content, flex-start, etc). It does this performantly and doesn't trigger browser layout mechanisms with each animation frame by animating layout-related structures with transforms under the hood rather than the specified layout CSS property.

An example of the animate prop on a motion component is provided below:

<motion.div layout />
Examples of text and image animations using motion layouts

Here is an example that uses motion layout to animate its expanded parent element on click:

Code:

<motion.div
layout
data-expanded={isOpen}
initial={{ borderRadius: 50 }}
className="flex h-[100px] w-[100px] items-center justify-center bg-black data-[expanded=true]:h-[200px] data-[expanded=true]:w-[400px]"
onClick={() => setIsOpen(!isOpen)}
>
<motion.div layout className="h-10 w-10 rounded-full bg-white" />
</motion.div>

typescript zod
  • Gestures

    motion components add a straightforward but effective collection of UI gesture handlers to React's core set of event listeners. At the moment, it supports gesture detection for hover, tap, pan, and drag is supported. You can add several event listeners to your motion component for each gesture.

An example of a gesture handler on a motion component is shown below:

Below is an example of a hover gesture handler:

<motion.button
whileHover={{
scale: 1.2,
transition: { duration: 1 },
}}
whileTap={{ scale: 0.9 }}
/>
Examples of text and image animations using motion gestures

Below is an example of a scale animation displayed on hover:

Code:

<motion.div
className="h-[80px] w-[200px] cursor-pointer rounded-[50px] bg-[#00ccff]"
whileHover={{ scale: 1.1 }}
transition={{ type: "spring", stiffness: 400, damping: 10 }}
/>

typescript zod
  • Transitions

    motion components can accept a transition prop, which specifies the type of animation used while animating CSS properties. In the transition props object, we can specify the duration, delay, ease properties of the transition.
Examples of animations using motion transitions

An example of the transition prop with duration, ease, and delay on a motion component is shown below:

Code:

<motion.div
className=" h-[200px] w-[200px] rounded-full bg-black"
initial={{ opacity: 0, scale: 0.5 }}
animate={{ opacity: 1, scale: 1 }}
transition={{
duration: 0.8,
delay: 0.5,
ease: [0, 0.71, 0.2, 1.01],
}}
/>

View:

typescript zod

the transition props can also receive props that specify which sort of animation to utilize (Tween, Spring, or Inertia).

Code:

<motion.div
className="flex items-center justify-center text-white w-[200px] h-[200px] rounded-full bg-black"
animate={{ y: 100 }}
transition={{ type: "spring", stiffness: 200 }}
>
Transition : Spring
</motion.div>

<motion.div
className="flex items-center justify-center text-white w-[200px] h-[200px] rounded-full bg-black"
animate={{ y: 100, pathLength: 1 }}
transition={{ type: "tween", duration: 3, }}
>
Transition: Tween
</motion.div>

<motion.div
className="flex items-center justify-center text-white w-[200px] h-[200px] rounded-full bg-black"
animate={{ y: 100 }}
transition={{ type: "inertia", velocity: 120 }}
>
Transition: Inertia
</motion.div>

Examples of other animations with motion components

AnimatePresence

Components removed from the React tree can be animated out using the AnimatePresence component.

This component solves many cases such as animating an element on react that was conditionally rendered as React lacks a lifecycle method that supports the notification of components to be unmounted as well as allowing them to defer unmounting until after an action (like an animation) has been executed.

Examples of animations using AnimatePresence

An example below is an animation done on a conditionally rendered div box.

Code:

import { useState } from "react";
import { motion, AnimatePresence } from "framer-motion";

const App = () => {
const [show, setShow] = useState(true);

return (
<div className="mt-20 flex h-screen max-h-screen w-full flex-col items-center justify-start">
<div className="flex flex-col items-center p-0 pb-[50px]">
<motion.button
className="rounded-[10px] bg-black p-4 text-white"
whileTap={{ scale: 0.95 }}
onClick={() => {
setShow(!show);
}}
>
{show ? "Hide" : "Show"}
</motion.button>
</div>

<AnimatePresence>
{show ? (
<motion.div
initial={{ opacity: 0 }}
animate={{ opacity: 1 }}
className="m-0 flex h-[150px] w-[150px] items-center justify-center rounded-[30px] bg-black text-white"
/>
) : null}
</AnimatePresence>
</div>
);
};

Hooks in Framer

useSpring

A motion value can be animated in a spring fashion through the useSpring hook.

The useSpring hook generates a motion value that animates to its latest target value using a spring animation. The target can be set manually using .set methods, or automatically by handing in another motion value.

useSpring can be initialized with a number.

const spring = useSpring(0);

Or, with a motionValue provided by framer

const x = useMotionValue(0);
const spring = useSpring(x);

UseSpring can be configured using the standard spring transition options.

useSpring(x, { stiffness: 1000, damping: 10 });

Use cases of the useSpring hook.

An example is to utilize the useSpring hook to animate the scale parameters of an element when the useEffect hook is triggered or when the element is hovered over.

Code:

import { useEffect } from "react";
import { motion, useSpring } from "framer-motion";

const App = () => {
const x = useSpring(0.5);
const y = useSpring(0.5);

useEffect(() => {
x.set(1);
}, []);

return (
<div>
<motion.div
className="flex h-10 w-full cursor-pointer items-center justify-center rounded-lg bg-black p-4 text-sm text-white"
style={{ scale: x }}
>
Spring scale animation on useEffect (component mounts)
</motion.div>

<motion.div
className="flex h-10 w-full cursor-pointer items-center justify-center rounded-lg bg-black p-4 text-sm text-white"
onHoverStart={() => y.set(1)}
style={{ scale: y }}
>
Spring scale animation on Hover
</motion.div>
</div>
);
};

useScroll

The useScroll hook is a hook in Framer Motion that is used to watch scroll positions on an element or page. It is frequently used to create scroll-linked animations such as progress bars and parallax effects.

the useScroll hook returns four motion values:

  • ScrollX/Y: The absolute scroll position of the X and Y axis (in pixels).
  • scrollXProgress/YProgress: The scroll position (of the X and Y axis) between the specified offsets, expressed as a value between 0 and 1.

Use cases of the useScroll hook.

Let's look at an example of how we can use motion values to construct the classic scroll indicator. Simply send the scrollYProgress motion value to the styleX style property of the progress bar element, as demonstrated in the code example below.

Code:

<motion.div className="progress-bar bg-red-500 fixed top-0 left-0 right-0 h-2.5 origin-left" style={{ scaleX }} />

The useScroll motion values can be combined with other motion value hooks, such as useTransform and useSpring, to create sophisticated animations like the one shown below.

Code:

const data = [
{
id: 1,
text: "Canyon",
url: "https://images.pexels.com/photos/19561297/pexels-photo-19561297.jpeg?auto=compress&cs=tinysrgb&w=600&lazy=load",

},
];

function Images({ text, url }: { text: string; url: string }) {
const ref = useRef(null);
const { scrollYProgress } = useScroll({ target: ref });
const scale = useSpring(useTransform(scrollYProgress, [0, 1], [10, 20]), {
stiffness: 100,
damping: 5,
});
return (
<section className="relative h-screen border">
<div className="absolute inset-0 rounded-[5px]" ref={ref}>
<img className="absolute h-full w-full" src={url} alt={text} />
<motion.h2
className="absolute left-[45%] top-[50%] -translate-x-1/2 text-[20px] font-bold leading-[1.2] -tracking-[2px] text-red-500"
style={{ scale }}
>
{text}
</motion.h2>
</div>
</section>
);
}

function App() {
return (
<div className="App">
{data.map((img) => (
<Images key={img.id} text={img.text} url={img.url} />
))}
</div>
);
}

useTransform

The useTransform hook generates a motionValue by modifying the output of one or more other motionValues.

const opacity = useTransform(
x,
// Map x from these values:
[0, 100],
// Into these values:
[1, 0],
);

We may use the useTransform to define a new motion value called opacity. By specifying an input and output range, we can say, "When x is 0, opacity should be 1. When x is 100, opacity should be zero."

Use cases of the useTransform hook.

An example is to utilise the useTransform hook to animate the background parameters of an element on hover.

Code:

import { motion, useTransform, motionValue } from "framer-motion";

const App = () => {
const x = useMotionValue(0);
const y = useMotionValue(0);

const backgroundColor = useTransform(x, [0, 100], ["#fff", "#000"]);

const color = useTransform(y, [0, 100], ["#000", "#fff"]);

return (
<div>
<motion.div
className="flex h-10 w-full cursor-pointer items-center justify-center rounded-lg bg-black p-4 text-sm text-white"
style={{
backgroundColor,
color,
}}
animate={{
transition: {
duration: 0.8,
delay: 0.5,
ease: [0, 0.71, 0.2, 1.01],
},
}}
onMouseEnter={() => {
x.set(100);
y.set(100);
}}
onMouseLeave={() => {
x.set(0);
y.set(0);
}}
>
useTransform hook background color animation on hover
</motion.div>
</div>
);
};

Another example is to combine the useTransform hook with the useSpring hook to get a spring animation on a transformed motion value on hover.

Code:

import { motion, useSpring, useTransform, useMotionValue } from "framer-motion";

const App = () => {
const springConfig = { stiffness: 100, damping: 5 };

const scaleMV = useMotionValue(0.5);
const transformMV = useMotionValue(50);

const scale = useSpring(useTransform(scaleMV, [0, 1], [0, 1]), springConfig);

const translateX = useSpring(
useTransform(transformMV, [0, 100], [0, 50]),
springConfig,
);

return (
<div>
<motion.div
className="flex h-10 w-full cursor-pointer items-center justify-center rounded-lg bg-black p-4 text-sm text-white"
style={{
scale,
rotateX: translateX,
}}
onMouseEnter={() => {
scaleMV.set(1);
transformMV.set(50);
}}
onMouseLeave={() => {
scaleMV.set(0.5);
transformMV.set(0);
}}
>
useTransform combination with useSpring
</motion.div>
</div>
);
};
typescript zod

useVelocity

When a motion value is supplied, the useVelocity hook takes it and provides a new one that updates with the velocity of the motion value.

Code:

import { useMotionValue, useVelocity } from "framer-motion";

function Component() {
const x = useMotionValue(0);

const xVelocity = useVelocity(x);

useEffect(() => {
return xVelocity.onChange((latestVelocity) => {
console.log("Velocity", latestVelocity);
});
}, []);

return <motion.div style={{ x }} />;
}

View:

typescript zod

Use cases of the useVelocity hook.

In the example below, we create a velocity motion value (which updates when the element moves) from a spring animation and then translate it to a scale and background motion value, which we will utilize on our element.

const App = () => {
const pink = (saturation: number) => `hsl(327, ${saturation}%, 50%)`;
const x = useMotionValue(0);

const xSmooth = useSpring(x, { damping: 50, stiffness: 400 });

/**
* Create a motion value from the smoothed output of x
*/
const xVelocity = useVelocity(xSmooth);

/**
* Transform the velocity of x into a scale motion value
*/
const scale = useTransform(xVelocity, [-3000, 0, 3000], [2, 1, 2], {
clamp: false,
});

/**
* Transform the velocity of x into a range of background color intensities
*/
const backgroundColor = useTransform(
xVelocity,
[-2000, 0, 2000],
[pink(100), pink(0), pink(100)],
);

return (
<div>
<motion.div
className="h-20 w-20 rounded-[30px] bg-[#ff008c]"
drag="x"
dragElastic={1}
dragConstraints={{ left: -200, right: 200 }}
style={{ x, scale, backgroundColor }}
/>
</div>
);
