Best way to exclude admin section from client js files?

[nullday0]

The goal is to extract admin section components and everything from main js bundle.

I would like to extract admin pieces into separate js files with some prefix (say, admin-<hash>.chunk.js), and then limit access to js files with such prefix on backend side (using express or whatever) using sessions.

The question is what tools can I use to achieve this?
Seems like there is code splitting on route level, but how to manage each route's build filename, to add that admin prefix?

This is a security issue to me, for example, there could be some admin pages having some sensitive internal directions/instructions. And as it's static data, it will be packed into final js bundle, and some bad guys could reverse engineer public js, get admin paths and fetch these chunks of JS, and basically read all these templates with sensitive info.
I can always deploy a separate admin app, but it's not an option for some projects.

Any input will be appreciated, thanks.
