zksync-crypto in next.js cant build. node.js and web.js should merge.

Environment

Mainnet

Acknowledgement

• I understand that issues are expected with the Go SDK as they are being updated.

Issue Description

In next.js, it is impossible to accurately obtain whether the crypto file type is node or web, resulting in packaging failure.

Expected Behavior

The packaging should be successful. Is it possible not to distinguish the file type, but to distinguish the node or web environment in the file?

Code Example

'use client'

import zk from 'zksync-crypto' or import zk from 'zksync-crypto/dist/zksync-crypto-web'

export default function Bridge() {
console.log(zk)
return null
}

and => npm run build

will find a error:
1. Error: Cannot find module 'util'
2. ReferenceError: window is not defined

Hi @Alan-Cn What are you trying to build? zksync-crypto is a quite old package and you might want to use zksync-ethers instead.

I'll leave you a link to our docs in case it helps you:

• zksync-ethers v5: https://docs.zksync.io/build/sdks/js/getting-started.html
• zksync-ethers v6: https://docs.zksync.io/build/sdks/js/zksync-ethers/getting-started.html

[Alan-Cn]

What I need is functional support for zksync-lite. Can the two copies you sent support zksync-lite?

[uF4No]

No, zksync-ethers is for zkSync Era.

For zkSync Lite, have you tried following the examples in this section of the docs? Also, check out this appendix to run the zksync lite library in the browser.
