AWS Website: SvelteKit

Deploys a SvelteKit app to AWS with AWS.Website.SvelteKit — no svelte.config.js adapter, no CDK.

The resource builds the app with SvelteKit's own Vite pipeline and a wrangler-free in-memory AWS adapter, deploys the server output on a streaming Lambda Function URL, and serves client assets + prerendered pages from S3 behind CloudFront. Values passed via env are exposed to server routes through process.env.

const site = yield* AWS.Website.SvelteKit("SvelteKitSite", {
  env: {
    GREETING: "Hello from SvelteKit on AWS!",
  },
});

Commands

bun alchemy deploy   # build + deploy
bun alchemy dev      # SvelteKit's Vite dev server (Node SSR, HMR)
bun alchemy destroy  # tear down

Notes

@alchemy.run/frontend-frameworks must be installed in the project — the server's source provider is loaded from its /sveltekit export at deploy time.
Unchanged projects skip the build and deploy entirely (the project tree is content-hashed, respecting .gitignore).
In alchemy dev, the site is kit's own Vite dev server (plain Node SSR) — already the AWS Lambda programming model, process.env included. No cloud resources are created; wrap the site in Alchemy.remote() to deploy the real infrastructure even during dev.
