Library showing animation of number changes in react.js

Test

Props

name	type	default	description
animateToNumber	number	none	Number to be animated
fontStyle	React.CSSProperties?	none	Style of number text
includeComma	boolean?	false	Whether the number contains commas
locale	string?	en-US	Formats animated number as per locale. Also it should be used with `inculdeComma` prop. For list of locales, search for "BCP 47 language tags"
configs(1)	SpringConfig[]?	config.default	This module is using react-spring and you can refer to this config option. If you pass multiple settings, an animation is randomly assigned to each number. DO NOT USE `duration` because of a bug that hasn't been fixed yet
configs(2)	(number, number): SpringConfig	none	The first parameter gives information about the number to be changed, And the second parameter gives information about the order of the changing numbers. You can use that information to adjust the animation by returning the config

Custom Style

you can use className animated-container to style container (example)
if you want to customize font style. Just ues fontStyle prop

Next JS

You have to use dynamic imports to ensure that this library is imported on the client side only.

Import the library like this:

import dynamic from "next/dynamic";
const AnimatedNumbers = dynamic(() => import("react-animated-numbers"), {
  ssr: false,
});

import React from "react";
import AnimatedNumbers from "react-animated-numbers";
import "./App.css";

function App() {
  const [num, setNum] = React.useState(331231);
  return (
    <div className="container">
      <AnimatedNumbers
        includeComma
        animateToNumber={num}
        fontStyle={{ fontSize: 40 }}
        locale="en-US"
        configs={[
          { mass: 1, tension: 220, friction: 100 },
          { mass: 1, tension: 180, friction: 130 },
          { mass: 1, tension: 280, friction: 90 },
          { mass: 1, tension: 180, friction: 135 },
          { mass: 1, tension: 260, friction: 100 },
          { mass: 1, tension: 210, friction: 180 },
        ]}
      ></AnimatedNumbers>

      <AnimatedNumbers
        animateToNumber={num}
        fontStyle={{ fontSize: 32 }}
        configs={(number, index) => {
          return { mass: 1, tension: 230 * (index + 1), friction: 140 };
        }}
      ></AnimatedNumbers>
      <div>
        <button onClick={() => setNum((state) => state + 31234)}>+</button>
        <button onClick={() => setNum((state) => state - 31234)}>-</button>
      </div>
    </div>
