Describe the bug

I'd like to use the same syntax for my client side assertions as my build time testing framework. Unfortunately, Vite seems to load Node.js dependent code when you import Vitest. Is Vitest not compatible with browsers?

ERROR: No matching export in "browser-external:fs" for import "existsSync"

I'm using v0.8.4: https://unpkg.com/browse/vitest@0.8.4/package.json
