Hide Nextjs code in the static chunks

[Pravin7108]

Summary

Secret keys in the CSR gets exposed while using environmental variables and Javascript Obfuscation

Additional information

Hello everyone , 

I have been Nextjs 14.0.2 for my project. I use env files and i works good in the SSR, but in the CSR the variables that I used in the vercel are directly exposed in the chunks files of the source .
Even debugger can show the keys i used.
I need to do javascript obfuscation or hide the confidential data showing in the chunk.
Need a good guidance for sorting out this issue.

Thanks in advance.

Can you explain, maybe with pseudocode, the kind of sensitive/secret data, and why it ends up in the client, and if so, why is it needed there?
