NextJS project compilation fails with JSEncrypt

I've installed JSEncrypt npm package for asymmetric encryption. But when I run the project I get the below error

Server Error ReferenceError: window is not defined

I even tried to dynamically load the JSEncrypt.min.js file in the project.

Can some one help resolving this?

Use dynamic import provided by Next.js. Import JSEncrypt only when you need to use it instead of importing it at the top of a module. The code below works for me.

async function decrypt() {
  const JSEncrypt = (await import('jsencrypt')).default
  var encryptor = new JSEncrypt()
  /* DO SOMETHING */
}

Thats because window is not defined while Server Side Rendering.
Importing the component (where you are including JSEncrypt) with next/dynamic and SSR set to false should fix the issue.
Ex.

import dynamic from 'next/dynamic'
const ComponentWithJSEncrypt = dynamic(
  () => import('../components/myComponent'), // path of your component
  { ssr: false }
)
