Support for define global constants from vite.config

[timleers]

Clear and concise description of the problem

In our webapp we are using vite's define for global constants. Unfortunately our tests using these constants are failing because the variables are not defined. Seems like vitest is ignoring everything included in the define context of the vite.config.js.

Do you plan to support that or did i miss something and its already working?

Suggested solution

Parse 'define' part of the vite.config and provide items as constants.

Alternative

Not use define in vite.config

Additional context

if there is anything i can do to support this awesome project please let me know. I'm happy to contribute

Could you please provide a reproduce demo ? I tried it and everything was fine.

Seems like the issue occurs only when using the constant within a vue component:
