Getting Started with Framer Motion
Before diving into the exciting world of Reactjs animations with Framer Motion, let's set up our development environment and install the necessary dependencies. This ensures a smooth and efficient animation creation process.
Installation
To install Framer Motion, you can use npm or yarn. Open your terminal and run the following command:
npm install framer-motion # or yarn add framer-motion Once the installation is complete, you can import Framer Motion components and functions into your Reactjs components and start adding animations.
Basic Usage
Let's create a simple animation to demonstrate the basic usage of Framer Motion. We'll animate the opacity of a Reactjs component when it mounts.
import { motion } from "framer-motion"; function MyComponent() { return ( Hello, Framer Motion! ); } export default MyComponent; In this example, we're using the motion.div component, which is a special div component provided by Framer Motion. We're setting the initial property to { opacity: 0 }, which means the component will initially be invisible. We're then setting the animate property to { opacity: 1 }, which means the component will animate to full opacity. Finally, we're setting the transition property to { duration: 1 }, which means the animation will take 1 second to complete.
Transitions and Variants
Framer Motion provides a powerful system for creating complex animations using transitions and variants. Let's explore these concepts in more detail.
Transitions
Transitions define how an animation should progress over time. You can customize various properties of a transition, such as duration, delay, ease, and type.
Move me! In this example, we're animating the x property of the component to 100. We're setting the duration to 0.5 seconds, the delay to 0.2 seconds, and the ease to "easeInOut". The ease property controls the acceleration and deceleration of the animation.
Variants
Variants are sets of animation values that you can reuse across multiple components. This is a great way to keep your code organized and DRY (Don't Repeat Yourself).
const variants = { hidden: { opacity: 0 }, visible: { opacity: 1 }, }; function MyComponent() { return ( Hello, Variants! ); } In this example, we're defining a variants object with two variants: hidden and visible. The hidden variant sets the opacity to 0, and the visible variant sets the opacity to 1. We're then using these variants in our motion.div component by setting the initial property to "hidden" and the animate property to "visible".
Gesture-Based Interactions
Framer Motion makes it easy to create gesture-based interactions, such as hover effects, tap animations, and drag-and-drop functionality.
Hover Effects
Let's create a simple hover effect that scales a component when the user hovers over it.
Hover me! In this example, we're using the whileHover property to define the animation that should occur when the user hovers over the component. We're setting the scale property to 1.1, which means the component will scale up to 110% of its original size. We're also setting the transition property to { duration: 0.3 }, which means the animation will take 0.3 seconds to complete.
Tap Animations
Let's create a tap animation that briefly scales down a component when the user taps on it.
Tap me! In this example, we're using the whileTap property to define the animation that should occur when the user taps on the component. We're setting the scale property to 0.9, which means the component will scale down to 90% of its original size. We're also setting the transition property to { duration: 0.1 }, which means the animation will take 0.1 seconds to complete.
Scroll Animations
Framer Motion also allows you to create scroll animations that are triggered as the user scrolls down the page. This can be used to create parallax effects, reveal animations, and other engaging visual experiences.
Using useScroll
The useScroll hook provides information about the scroll position of the page. You can use this information to drive your animations.
import { useScroll, motion } from "framer-motion"; function MyComponent() { const { scrollYProgress } = useScroll(); return ( ); } In this example, we're using the useScroll hook to get the scrollYProgress value, which represents the percentage of the page that has been scrolled. We're then using this value to set the scaleX property of a motion.div component, which creates a progress bar that fills up as the user scrolls down the page.
CodeSandbox Examples
Interactive examples are crucial for understanding and experimenting with animations. Below are embedded CodeSandbox examples for each of the concepts discussed. Feel free to fork them and try different things.

Optimization Strategies
To ensure smooth and performant animations, it's important to optimize your code and avoid common pitfalls.
Using useMemo
The useMemo hook can be used to memoize expensive calculations and prevent unnecessary re-renders.
import { useMemo } from "react"; import { motion } from "framer-motion"; function MyComponent({ data }) { const variants = useMemo(() => ({ hidden: { opacity: 0, x: -100 }, visible: { opacity: 1, x: 0 }, }), [data]); return ( {data.name} ); } In this example, we're using the useMemo hook to memoize the variants object. This prevents the variants object from being re-created on every render, which can improve performance.
Avoiding Layout Thrashing
Layout thrashing occurs when you read and write to the DOM in the same frame. This can cause the browser to recalculate the layout multiple times, which can significantly impact performance. To avoid layout thrashing, try to read and write to the DOM in separate frames.
Common Bugs and Fixes
Encountering issues is part of the development process. Here are some common bugs and how to fix them when working with Reactjs animations using Framer Motion.
Animation Not Triggering
Sometimes, animations might not trigger as expected. Ensure that the initial and animate properties are correctly set and that the component is properly mounted. Additionally, double-check your variant definitions.
// Ensure initial and animate are correctly set Content to animate Performance Issues
If you notice performance issues with complex animations, try simplifying the animations or optimizing the components involved. Memoizing components with React.memo can also help.
// Memoize the component to prevent unnecessary re-renders import React from 'react'; const MyComponent = React.memo(function MyComponent(props) { // Component logic here return ... ; }); 🔧 Tools for Debugging
Debugging Reactjs animations can be challenging, but these tools can help streamline the process:
Framer Motion Devtools
The Framer Motion devtools extension for Chrome and Firefox can provide insights into the animations' performance, transition properties, and more.
React Profiler
The React Profiler can help identify performance bottlenecks in your Reactjs components, including those related to animations.
Browser Developer Tools
The browser's built-in developer tools can be used to inspect the DOM, monitor network requests, and profile JavaScript execution.
