React Spring Loop Object

Last Updated : 03 Oct, 2022

React spring is an animation library that makes animating UI elements simple. It is based on spring physics which helps it to achieve a natural look and feel. It is different from other animation libraries where someone has to deal with curves, easing, and time durations, all of which are in sync with each other.

Platforms: React spring is a cross-platform library, it supports react, react-native, web, and many more platforms. It also has support for all browsers.

Loop Object: It is used to animate any object in a loop that will repeat.

Syntax:

useSpring({ 
    loop: true
})

Steps to create a React Spring App:

Step 1: Create a new application using the following command.

npx create-react-app reactspringdemo

Step 2: Now move the created project folder using the following command.

cd reactspringdemo

Step 3: Install the react spring library.

npm install react-spring

Project Structure: It will look like the following.

Example1: In the below code, we will use the above syntax to demonstrate the loop object using React Spring.

    const styles = useSpring({ 
        loop: true, 
        from: { rotateZ: 0 }, 
        to: { rotateZ: 180 }, 
        duration: 2000,

                display: "flex", 
                alignItems: "center", 
                justifyContent: "center", 
                color: "green", 
                ...styles, 
            }} 
        > 
            GFG 
        </animated.div> 
    ); 
}; 
  
export default LoopingObject; 

App.js

import React from 'react'
import GFG from './GFG'
  
function App() { 
    console.log('hello') 
    return ( 
        <> 
            <GFG /> 
        </> 
    ); 
} 
  
export default App; 

To run the Application: Run the following command:

npm start

Output:

Example2: In the below code, we will use the above syntax to demonstrate the loop object using React Spring. In this example, we are rotating the object by 360 degrees.
