Deploy a SvelteKit app on Enzonic

SvelteKit picks its deployment target through an adapter. Deploy runs adapter-node builds as a Node.js server (node build/index.js) and serves adapter-static builds as plain files. adapter-auto has no Enzonic target, so choose one of the two.

Deploy SvelteKit Docs

At a glance

What Enzonic Deploy does with a SvelteKit project when you connect it. You can override any of it in the project settings.

Language: JavaScript / TypeScript
Detected from: @sveltejs/kit in dependencies; @sveltejs/adapter-node means server, @sveltejs/adapter-static means static
Build command: vite build (or your build script)
Output: build
Runs as: Server or Static

Dependencies install with the package manager your lockfile names: npm ci, pnpm install --frozen-lockfile, yarn install --immutable (Berry) or --frozen-lockfile, or bun install --frozen-lockfile. Node.js 18, 20, 22 and 24 are available. Deploy reads engines.node in package.json, then .nvmrc or .node-version, and uses Node.js 22 when nothing pins a version.

How it runs

Server
With @sveltejs/adapter-node: build/index.js and build/handler.js are started with node build/index.js.
Static
With @sveltejs/adapter-static: the build folder is served as files, with your fallback page if you set one.

Deploy SvelteKit step by step

1Install the adapter you want: npm i -D @sveltejs/adapter-node (server) or @sveltejs/adapter-static (static).
2Set it in svelte.config.js and commit.
3Create the project on deploy.enzonic.com from the repository and deploy.

svelte.config.js

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

export default {
  preprocess: vitePreprocess(),
  kit: { adapter: adapter() },
};

Connect a database to SvelteKit

Create a database on Enzonic Databases (or from the project's settings) and its connection string is added to the project's environment variables. This example uses PostgreSQL.

src/routes/+page.server.ts

import postgres from 'postgres';
import { env } from '$env/dynamic/private';

const sql = postgres(env.DATABASE_URL);

export async function load() {
  const posts = await sql`select id, title from posts order by id desc limit 20`;
  return { posts };
}

$env/dynamic/private reads the value at runtime, so the same build works for previews and production.

Postgres projects get two variables: DATABASE_URL through the connection pooler for the app, and DATABASE_URL_UNPOOLED for migrations.

Things to know

With adapter-auto the build still runs, but Deploy reports that it has no Enzonic target and asks you to pick adapter-node or adapter-static.
$env/static/private inlines values at build time: changing a variable then needs a new deployment. Prefer $env/dynamic/private for secrets.
