// This file isn't processed by Vite, see https://github.com/vikejs/vike/issues/562
// Consequently:
//  - When changing this file, you needed to manually restart your server for your changes to take effect.
//  - To use your environment variables defined in your .env files, you need to install dotenv, see https://vike.dev/env
//  - To use your path aliases defined in your vite.config.js, you need to tell Node.js about them, see https://vike.dev/path-aliases

// If you want Vite to process your server code then use one of these:
//  - vavite (https://github.com/cyco130/vavite)
//     - See vavite + Vike examples at https://github.com/cyco130/vavite/tree/main/examples
//  - vite-node (https://github.com/antfu/vite-node)
//  - HatTip (https://github.com/hattipjs/hattip)
//    - You can use Bati (https://batijs.github.io/) to scaffold a Vike + HatTip app. Note that Bati generates apps that use the V1 design (https://vike.dev/migration/v1-design) and Vike packages (https://vike.dev/vike-packages)
