Cannot find module 'crypto-js' or its corresponding type declarations

Question

I have a project and this project is displaying "QR code" and then for some reason I have to use a certain encoder function and for that I used this library:

Crypto

i am trying to use Crypto, but i get this error:

Cannot find module 'crypto-js' or its corresponding type declarations.

file.tsx:

import CryptoJS from 'crypto-js';

const ENC_KEY =
    '50b3cc356d8f34017b3cce1a021389458b898ae85a816201695d11cb87fa1769';
const IV = '07ed0f192b6d8f36c24bd802e0a52cd4';


/**
 * 
 * @param encryptedQR it should be a hex based string
 * @returns a utf8 based decrypted string
 */
export function decrypt(encryptedQR: string) {
    const key = CryptoJS.enc.Hex.parse(ENC_KEY);
    const iv = CryptoJS.enc.Hex.parse(IV);
    const encryptedHex = CryptoJS.enc.Hex.parse(encryptedQR);
    const encrypted = CryptoJS.enc.Base64.stringify(encryptedHex);
    const decrypted = CryptoJS.AES.decrypt(encrypted, key, {
        iv,
        mode: CryptoJS.mode.CBC,
        padding: CryptoJS.pad.NoPadding,
    });
    return CryptoJS.enc.Utf8.stringify(decrypted).trim();
}

Answer 1

I solve my problem with this steps:

1- npm install crypto-js --save
2- npm install @types/crypto-js
3- 
      from: import { CryptoJS } from ‘crypto-js’;
      to: import * as CryptoJS from ‘crypto-js’;

Or

1- yarn add crypto-js --save
2- yarn add @types/crypto-js
3- 
      from: import { CryptoJS } from ‘crypto-js’;
      to: import * as CryptoJS from ‘crypto-js’;
