How to obfuscate data via transformer

End user with adequate knowledge can easily copy JSON data in plain text from network requests in browser dev tools. I'd like to make copying JSON data a bit more difficult for these advance users. Looks like obfuscation needs to be done in transformer. Does anyone have ideas how to implement obfuscation along with superjson within transformer?

import { uneval } from 'devalue';
import superjson from 'superjson';

export const transformer = {
input: superjson,
output: {
serialize: (object) => uneval(object),
deserialize: (object) => eval(`(${object})`),
},
};

import { uneval } from 'devalue';
import superjson from 'superjson';

export const transformer = {
input: superjson,
output: {
serialize: (object) => uneval(object),
deserialize: (object) => eval(`(${object})`),
},
};

Write your own transformer which wraps superjson and base64 encodes everything What also whhhyyyy, obfuscation is not security, it's just spending your time making debugging harder for yourself

So true 👍 After digging into type info of tRPC transformer and superjson, it seems quite an quite easy job to do obfuscation 😅
