and then i ran npm audit --prod,

                       === npm audit security report ===                        

found 0 vulnerabilities
 in 78 scanned packages

does it mean, it doesn't affect in production environment ?

And once i access the given link in audit report for more info, it says,

No fix is currently available. Consider using an alternative package until a fix is made available.

So is there any alternatives available for http-proxy package ?

Thanks in advance.

Answer 1

does it mean, it doesn't affect in production environment ?

Yes, it will not affect your prod environment. http-proxy is only used in your dev dependency as you can see in the row "Depenceny of".

So is there any alternatives available for http-proxy package ?

I don't think so since Angular uses it itself. We have to wait until there is an official fix.
