Which configuration dirs must be set with root?

[Farnsi]

vite Example:

export default defineConfig({
  root: './src',
  plugins: [
    pluginAPIRoutes({
      cacheDir: '../.api', // this starts without an error
    }),
  ],
  //...
}

Call a route errors Error: Cannot find module 'express' imported from '/home/myproject/.api/configure.js'
Express is installed.

With absolute path it works. cacheDir: process.cwd() + '/.api',

Na not working. When you use absolute path it will not create .api with configure.ts,....

And the next question, which paths must be set, if you want to use api-Files outside of src?
