Cloudflare SvelteKit Workers D1

Overview

Provide a clear, current workflow to connect a SvelteKit TypeScript app to Cloudflare Workers and D1, including adapter setup, Wrangler configuration, D1 bindings/migrations, local testing, and deployment instructions.

Workflow Decision Tree

Existing SvelteKit app -> Use the Manual Setup workflow in references/manual-workers-d1.md.
Brand new project -> Use the Cloudflare framework CLI flow in references/manual-workers-d1.md (C3 option).
User wants fastest/auto config -> Use references/wrangler-autoconfig.md (experimental) and still verify the generated config.

Core Workflow (Manual Setup)

Verify the latest Cloudflare + SvelteKit docs with web.run (adapter-cloudflare, Workers framework guide, D1 commands).
Add the Cloudflare adapter and update svelte.config.js.
Create or update wrangler.toml for Workers Assets and D1 bindings.
Create the D1 database and copy its binding block into wrangler.toml.
Add TypeScript platform typings and use platform.env.DB in server endpoints.
Create/apply migrations locally and remotely.
Build, test with Wrangler, then deploy.

Use the exact steps and snippets in references/manual-workers-d1.md.

D1 Integration Checklist

Ensure the binding name is a valid JS identifier and matches platform.env.<BINDING> in code.
Ensure wrangler.toml includes [[d1_databases]] with database_name + database_id.
Create and apply migrations with both --local and --remote as needed.
Update TypeScript declarations in src/app.d.ts.

Local Dev and Testing Guidance

Prefer SvelteKit dev server for general UI work.
For Cloudflare-specific behavior, build and run wrangler dev .svelte-kit/cloudflare.
Use adapter platformProxy options if local bindings need tweaks.

Writing Deployment Instructions

Be explicit about files, commands, and where to paste blocks.
Always include the wrangler.toml skeleton and D1 binding block.
Include verification steps (local dev and a deploy check).
If there is any uncertainty in versions or commands, re-check docs via web.run.
