Declare illegal variable names in minify/build?

[CodyCodes95]

Hey guys, got a quite niche one, wondering if anyone can help me out in solving it.

I develop React apps that are embedded into proprietary CMS websites. A bit unconventional, but yeah. These websites often have a lot of custom js on the page, and the global variables on the page conflict with variables that my Vite app builds into, causing errors. The only way around this is to disable minifying so I have control over the variable names, or modify each conflicting var after build.

What I would like to do is config my minify to NOT use certain variable names, is this at all possible?

Cheers,

Bump, any help would be greatly appreciated!

Experiencing the same currently, we have a site using knockout js, which defines the global variable ko.

The minified script now declares a vue component with this name and therefore breaking all user code on the site.
