    The error I'm getting:

    ERROR in ./src/ponents/Loading.jsx 9:33-39

export 'default' (imported as 'Loader') was not found in 'react-loader-spinner' (possible exports: Audio, BallTriangle, Bars, Circles, CradleLoader, Grid, Hearts, MutatingDots, Oval, Plane, Puff, RevolvingDot, Rings, TailSpin, ThreeDots, Triangle, Watch)

    Here is my code:

    import React from 'react';
import Loader from 'react-loader-spinner';

export const Loading = () => (
  <div className="flex justify-center items-center ">
    <Loader type="Puff" color="#00BFFF" height={550} width={80} />
  </div>
);

    Reset to default 8

    react-loader-spinner exports various loaders and you can use those loaders directly. And if you want to import all the loaders and use them. You can do it like this.

    import * as Loader from "react-loader-spinner";

function App() {
  return <Loader.TailSpin />;
}

    or

    import {TailSpin} from "react-loader-spinner";

function App() {
  return <TailSpin />;
}

    https://codesandbox.io/s/hopeful-herschel-652kq?file=/src/index.js:70-168

    You just need to import that specific loader you want, as there are many of them that react-loader-spinner exports. For example the code below is for Rings loader.

    All loader types are here on the official documentation.

    import { Rings } from 'react-loader-spinner';

export const Loading = () => (
  <div className="flex justify-center items-center ">
    <Rings color="#00BFFF" height={80} width={80} />
  </div>
);

    You can import specific one from react-loader-spinner

    import React from 'react'
import {Triangle} from 'react-loader-spinner'
const Loading = () => {
  return (
    <div className='flex justify-center items-center'>
        <Triangle type='Puff' color='#00BFFF' height={550} width={80} />
    </div>
  )
}

export default Loading

    https://mhnpd.github.io/react-loader-spinner/ Here you can find many examples of Loaders

    make sure use the correct method of import and Export ,It Normally occurs because false Way of importing and exporting

    Use this for Making and Importing the Loader Here we are targeting the specific loader from react-loader-spinner

    import React from 'react';
import { Rings } from 'react-loader-spinner';
export const Loading = () => (
  <div>
    <Rings color="#00BFFF" height={80} width={80} />
  </div>
);

    See carefully that we don't use default Here so to import in main ponent

    import {Loading}  from './Loading.jsx';
