Can I import server-side package in a file contains both server-side and client-side functionality?

[oran1248]

Let's say I have a file named utils.js, containing two functions s and c.
s is a server-side function (Being called on an /api endpoint handler), and uses mongodb package.
c is a client-side function (will be bundled and sent to the browser).

When compiling the app using next build, will it cause any issues?
Does webpack know to bundle only part of a file/module? (considering server-side functions and imports as a "dead code" since they only being called from a server-side code)

Thanks
