import { defineConfig } from 'astro/config';

import node from '@astrojs/node';

// https://astro.build/config
export default defineConfig({
  build: {
    // Example: Generate `page.html` instead of `page/index.html` during build.
    format: 'file'
  },
  adapter: node({
    mode: 'standalone'

});
