1. Introduction to Framer Motion

Framer Motion is a production-ready motion library for React, developed by Framer, a company known for its design and prototyping tools. It combines ease of use with powerful features, making it a go-to choice for adding animations to React applications.

Key Features

  • Declarative Syntax: Write animations in a way that’s natural within React’s component-based architecture.
  • Intuitive API: Easy-to-understand props and methods for common animation tasks.
  • Powerful Gestures: Built-in support for drag, hover, and tap interactions.
  • Variants and Orchestration: Manage complex animations and sequence them efficiently.

2. Setting Up Framer Motion in a React Project

To get started with Framer Motion, you need to install it in your React project. Assuming you have a React project set up, you can install Framer Motion using npm or yarn:

npm install framer-motion

or

yarn add framer-motion

After installation, you can start importing and using Framer Motion components in your React application.

3. Basic Animations

Let’s begin with some basic animations to get a feel for how Framer Motion works.

Animating a Simple Box

We’ll start by animating a simple box. Create a new component called AnimatedBox.js:

import React from 'react';
import { motion } from 'framer-motion';

const AnimatedBox = () => {
  return (
    <motion.div
      style={{
        width: 100,
        height: 100,
        backgroundColor: 'blue',
        margin: 'auto'
      }}
      animate={{ rotate: 360 }}
      transition={{ duration: 2 }}
    />
  );
};

export default AnimatedBox;

In this example:

  • We use the motion.div component to create an animatable div.
  • The animate prop specifies the end state of the animation (a full 360-degree rotation).
  • The transition prop controls the duration of the animation.

Hover and Tap Animations

Framer Motion makes it easy to add animations for hover and tap interactions. Let’s enhance our box to change color on hover and scale on tap.

import React from 'react';
import { motion } from 'framer-motion';

const InteractiveBox = () => {
  return (
    <motion.div
      style={{
        width: 100,
        height: 100,
        backgroundColor: 'blue',
        margin: 'auto'
      }}
      whileHover={{ scale: 1.2, backgroundColor: 'red' }}
      whileTap={{ scale: 0.8 }}
    />
  );
};

export default InteractiveBox;

Here:

  • whileHover prop specifies the animation to play when the element is hovered over.
  • whileTap prop specifies the animation to play when the element is tapped (or clicked).

4. Advanced Animations

Moving beyond basic animations, Framer Motion provides more advanced features such as keyframes, gestures, and exit animations.

Keyframes

Keyframes allow you to animate through a sequence of values. Let’s animate a box changing colors over time.

import React from 'react';
import { motion } from 'framer-motion';

const KeyframeBox = () => {
  return (
    <motion.div
      style={{
        width: 100,
        height: 100,
        margin: 'auto'
      }}
      animate={{ backgroundColor: ['blue', 'green', 'yellow', 'red'] }}
      transition={{ duration: 4, repeat: Infinity }}
    />
  );
};

export default KeyframeBox;

In this example:

  • The animate prop is an array of color values that the box will transition through.
  • The transition prop includes repeat: Infinity looping the animation indefinitely.

Gestures and Drag

Framer Motion also supports drag interactions, which can be particularly useful for creating sliders, carousels, or draggable elements.

import React from 'react';
import { motion } from 'framer-motion';

const DraggableBox = () => {
  return (
     <motion.div
       style={{
            width: 100,
            height: 100,
            backgroundColor: 'blue',
            margin: 'auto',
            cursor: 'grab'
      }}
    dragConstraints={{ top: -50, bottom: 50, left: -50, right: 50 }}
    whileDrag={{ scale: 1.2 }}    />
  );
};

export default DraggableBox;

In this example:

  • The drag prop makes the box draggable.
  • dragConstraints limits the draggable area.
  • whileDrag animates the box while it is being dragged.

Exit Animations

Exit animations allow you to animate a component when it is removed from the DOM. This can be useful for modals, notifications, or any component that needs to transition out gracefully.

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

const ExitAnimationBox = () => {
  const [isVisible, setIsVisible] = useState(true);

  return (
    <div>
      <button onClick={() => setIsVisible(!isVisible)}>Toggle</button>
      <AnimatePresence>
        {isVisible && (
          <motion.div
            style={{
              width: 100,
              height: 100,
              backgroundColor: 'blue',
              margin: 'auto'
            }}
            initial={{ opacity: 0 }}
            animate={{ opacity: 1 }}
            exit={{ opacity: 0 }}
          />
        )}
      </AnimatePresence>
    </div>
  );
};

export default ExitAnimationBox;

Here:

  • AnimatePresence enables exit animations for components.
  • The initial, animate, and exit props control the opacity of the box as it enters and exits.

5. Orchestrating Animations

For more complex animations, Framer Motion offers tools like variants and animation controls.

Variants

Variants allow you to define multiple animation states and switch between them easily.

import React from 'react';
import { motion } from 'framer-motion';

const boxVariants = {
  hidden: { opacity: 0, scale: 0.8 },
  visible: { opacity: 1, scale: 1 }
};

const VariantsBox = () => {
  return (
    <motion.div
      style={{
        width: 100,
        height: 100,
        backgroundColor: 'blue',
        margin: 'auto'
      }}
      initial="hidden"
      animate="visible"
      variants={boxVariants}
      transition={{ duration: 1 }}
    />
  );
};

export default VariantsBox;

In this example:

  • boxVariants defines two states: hidden and visible.
  • The component uses these variants to control the animation state.

Animation Controls

Animation controls give you programmatic control over animations, useful for triggering animations based on specific events or conditions.

import React from 'react';
import { motion, useAnimation } from 'framer-motion';

const ControlsBox = () => {
  const controls = useAnimation();

  return (
    <div>
      <button onClick={() => controls.start({ scale: 1.5, transition: { duration: 0.5 } })}>
        Enlarge
      </button>
      <motion.div
        style={{
          width: 100,
          height: 100,
          backgroundColor: 'blue',
          margin: 'auto'
        }}
        animate={controls}
      />
    </div>
  );
};

export default ControlsBox;

Here:

  • useAnimation hook provides control over the animation.
  • The button click triggers the animation to start with specified properties.

6. Practical Examples

Let’s apply what we’ve learned to some practical examples.

Modal with Animation

Animating a modal can enhance the user experience by providing smooth entry and exit transitions.

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

const Modal = ({ isVisible, onClose }) => {
  return (
    <AnimatePresence>
      {isVisible && (
        <motion.div
          className="backdrop"
          initial={{ opacity: 0 }}
          animate={{ opacity: 0.5 }}
          exit={{ opacity: 0 }}
          onClick={onClose}
        >
          <motion.div
            className="modal"
            initial={{ y: -50, opacity: 0 }}
            animate={{ y: 0, opacity: 1 }}
            exit={{ y: 50, opacity: 0 }}
            onClick={(e) => e.stopPropagation()}
          >
            <h2>Modal Content</h2>
            <button onClick={onClose}>Close</button>
          </motion.div>
        </motion.div>
      )}
    </AnimatePresence>
  );
};

const ModalExample = () => {
  const [isModalVisible, setModalVisible] = useState(false);

  return (
    <div>
      <button onClick={() => setModalVisible(true)}>Open Modal</button>
      <Modal isVisible={isModalVisible} onClose={() => setModalVisible(false)} />
    </div>
  );
};

export default ModalExample;

Here:

  • Modal component uses AnimatePresence to handle the mounting and unmounting of the modal.
  • The modal fades in and out and slides up and down on entry and exit.

Animated List Items

Animating list items can make dynamic lists more visually appealing.

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

const ListItem = ({ item }) => (
  <motion.li
    initial={{ opacity: 0, y: -20 }}
    animate={{ opacity: 1, y: 0 }}
    exit={{ opacity: 0, y: 20 }}
    transition={{ duration: 0.3 }}
  >
    {item}
  </motion.li>
);

const AnimatedList = () => {
  const [items, setItems] = useState(['Item 1', 'Item 2', 'Item 3']);

  const addItem = () => {
    setItems([...items, `Item ${items.length + 1}`]);
  };

  const removeItem = () => {
    setItems(items.slice(0, -1));
  };

  return (
    <div>
      <button onClick={addItem}>Add Item</button>
      <button onClick={removeItem}>Remove Item</button>
      <ul>
        <AnimatePresence>
          {items.map((item, index) => (
            <ListItem key={index} item={item} />
          ))}
        </AnimatePresence>
      </ul>
    </div>
  );
};

export default AnimatedList;

In this example:

  • Each list item is used AnimatePresence to animate its entry and exit.
  • Buttons allow for dynamically adding and removing items from the list.

Page Transitions

Framer Motion can also be used to create smooth transitions between pages.

import React from 'react';
import { motion } from 'framer-motion';
import { BrowserRouter as Router, Route, Switch, useLocation } from 'react-router-dom';

const HomePage = () => (
  <motion.div
    initial={{ opacity: 0 }}
    animate={{ opacity: 1 }}
    exit={{ opacity: 0 }}
    transition={{ duration: 0.5 }}
  >
    <h1>Home Page</h1>
  </motion.div>
);

const AboutPage = () => (
  <motion.div
    initial={{ opacity: 0 }}
    animate={{ opacity: 1 }}
    exit={{ opacity: 0 }}
    transition={{ duration: 0.5 }}
  >
    <h1>About Page</h1>
  </motion.div>
);

const PageTransitionExample = () => {
  const location = useLocation();

  return (
    <AnimatePresence exitBeforeEnter>
      <Switch location={location} key={location.pathname}>
        <Route path="/" exact component={HomePage} />
        <Route path="/about" component={AboutPage} />
      </Switch>
    </AnimatePresence>
  );
};

const App = () => {
  return (
    <Router>
      <PageTransitionExample />
    </Router>
  );
};

export default App;

Here:

  • AnimatePresence ensures that page transitions are animated.
  • Each page component defines its own animation for entry and exit.

7. Performance Considerations

While Framer Motion is optimized for performance, it’s essential to follow best practices to ensure smooth animations:

  • Limit DOM Elements: Animate only necessary elements to reduce computational load.
  • Use Transform Properties: Prefer transform (e.g., translate, scale, rotate) over properties like top, left, width, and height for smoother animations.
  • Batch Updates: Use motion.div similar components to batch updates for better performance.
  • Profile Animations: Use browser performance tools to profile your animations and identify bottlenecks.

8. Conclusion

Framer Motion provides a robust and intuitive API for adding animations to your React applications. From basic animations to complex gestures and orchestrations, Framer Motion makes it easy to enhance your UI with smooth, performant animations.

By following the examples and best practices outlined in this article, you can start creating engaging and dynamic user experiences in your React projects. Whether you are animating a simple box or orchestrating complex page transitions, Framer Motion has the tools you need to bring your UI to life.
