Creating Engaging SVG Animations with React-Tweenful

Chapter 1: Introduction to React-Tweenful
The react-tweenful library simplifies the process of adding animations to your React applications. In this guide, we'll explore how to begin animating SVG elements effectively.
Chapter 1.1: Setting Up SVG Animations
To animate SVGs, we utilize the SVG object from the react-tweenful library. Here’s a sample code snippet to illustrate:
import React from "react";
import { SVG, percentage, elastic } from "react-tweenful";
const circles = new Array(5).fill(0).map((_e, i) => ({
loop: true,
fill: hsl(${(i + 1) * 20 - 20}, 70%, 70%),
delay: ((i + 1) * 1500) / -10,
duration: 1500,
easing: elastic(2, 0.9),
transform: {
translate: "0 100px"},
style: {
transformOrigin: ${-200 + 120 * (i + 1)}px 250px},
animate: percentage({
"0%": { translate: "0px 100px", scale: 1 },
"50%": { translate: "0px -100px", scale: 0.3 },
"100%": { translate: "0px 100px", scale: 1 }
}),
r: 35,
cx: 100 * i + 50,
cy: 250
}));
export default function App() {
return (
<div className="bouncing-balls">
<svg
xmlns="http://www.w3.org/2000/svg"
x="0px"
y="0px"
viewBox="0 0 1000 500"
>
{circles.map((circle, i) => (
<SVG.circle key={i} {...circle}></SVG.circle>))}
</svg>
</div>
);
}
This code snippet demonstrates how to create a bouncing ball animation effect. The circles array holds various properties for each animated circle.
Key Animation Properties
- fill: Defines the fill color of the circle.
- loop: When set to true, the animation will repeat indefinitely.
- delay: Specifies the delay before the animation starts.
- duration: Indicates how long the animation lasts.
- easing: Controls the pacing of the animation.
- transform: Applies CSS transformations.
- style: Additional styles applied to the circle.
- animate: Specifies styles at different points in the animation.
- r, cx, cy: Represent the radius and the center coordinates of the circle.
In the JSX section, we create an SVG component that houses the animated circles. All animation properties are applied by spreading the circle's attributes.
Conclusion
Using the react-tweenful library, animating SVGs becomes a straightforward task.
