Describe the Bug

I am trying to access a D1 database defined in my wrangler.jsonc. The documentation for the svelte plugin make it seem as though it should just work but I don't see a database in my hooks.server.ts.

import type { Handle } from "@sveltejs/kit";
import { DB } from '$env/static/private';

export const handle: Handle = async ({ event, resolve }) => {
  // all undefined
  console.log(process.env.DB, import.meta.env.DB, DB);
}

svelte config

import { vitePreprocess } from '@sveltejs/vite-plugin-svelte';

/** @type {import('@sveltejs/kit').Config} */
const config = {
	// Consult https://svelte.dev/docs/kit/integrations
	// for more information about preprocessors
	preprocess: vitePreprocess(),
};

export default config;

vite config

import { sveltekit } from '@sveltejs/kit/vite';
import { defineConfig } from 'vite';
import { cloudflare } from "@cloudflare/vite-plugin";

export default defineConfig({
	plugins: [sveltekit(), cloudflare()]
});

Please provide any relevant error logs

It works with the adapter but I thought the idea of the Vite plugin is that I don't need an adapter anymore.

import adapter from "@sveltejs/adapter-cloudflare";
import { vitePreprocess } from '@sveltejs/vite-plugin-svelte';

/** @type {import('@sveltejs/kit').Config} */
const config = {
	// Consult https://svelte.dev/docs/kit/integrations
	// for more information about preprocessors
	preprocess: vitePreprocess(),

	kit: {
		adapter: adapter()
	}
};

export default config;

Hey the vite plugin does not work with sveltekit yet, but we're working on it with the svelte team :)

Ah ok, thanks for clarifying. I'll use the adapter for now then.

Thanks for the info, would you be able to hazard an ETA?

Using the adapter for development introduces a delay every time we save the files for rebuilding. It would be great if the vite plugin works so we get HMR.
