Using Framer Motion in React

1. Introduction

Framer Motion is a powerful library for animations in React applications. It provides a simple and declarative API for creating complex animations and transitions.

Key Takeaway: Framer Motion simplifies the process of adding animations to your React components.

2. Installation

To get started with Framer Motion, you need to install it via npm or yarn.

npm install framer-motion

yarn add framer-motion

3. Basic Usage

To use Framer Motion, you need to import the necessary components from the library. The basic component is motion.div, which can be used to animate a div element.

Example: Simple Animation

import { motion } from 'framer-motion';

const Box = () => {
    return (
        
    );
};

This example moves a blue box 100 pixels to the right over 0.5 seconds.

4. Advanced Animations

Framer Motion also allows you to create more complex animations using variants, gestures, and keyframes.

Example: Variants

const boxVariants = {
    hidden: { opacity: 0 },
    visible: { opacity: 1 },
};

const Box = () => {
    return (
        
    );
};

In this example, the box fades in from invisible to visible state.

Example: Gestures

const Box = () => {
    return (
        
    );
};

This box can be dragged around within specified constraints.

5. Best Practices

When using Framer Motion, consider the following best practices:

Keep animations performant by minimizing the number of animated properties.
Use variants to manage complex animations.
Ensure accessibility by providing fallbacks for non-JS users.
Leverage the exit prop for smoother component exits.
