TanStack Start

This guide shows how to initialize and deploy a TanStack Start application to Cloudflare using Alchemy.

Init

Section titled “Init”

Start by creating a new TanStack Start project with Alchemy:

Terminal window
bunx alchemy create my-tanstack-app --template=tanstack-start
cd my-tanstack-app

Log in to Cloudflare

Section titled “Log in to Cloudflare”

Authenticate once with your Cloudflare account:

Terminal window
bun wrangler login

Deploy

Section titled “Deploy”

Run the deploy script generated by the template:

Terminal window
bun run deploy

You’ll get the live URL of your TanStack Start application:

Terminal window
{
  url: "https://website.<your-account>.workers.dev",
}

Local Development

Work locally using the dev script:

Terminal window

Section titled “alchemy.run.ts”
/// <reference types="@types/node" />


import alchemy from "alchemy";
import { TanStackStart } from "alchemy/cloudflare";


const app = await alchemy("my-tanstack-app");


export const worker = await TanStackStart("website", {
  command: "bun run build",
});


console.log({
  url: worker.url,
});


await app.finalize();

types/env.d.ts

Section titled “types/env.d.ts”
// Auto-generated Cloudflare binding types.
// @see https://alchemy.run/concepts/bindings/#type-safe-bindings


import type { worker } from "../alchemy.run.ts";


export type CloudflareEnv = typeof worker.Env;


declare global {
  type Env = CloudflareEnv;
}


declare module "cloudflare:workers" {
  namespace Cloudflare {
    export interface Env extends CloudflareEnv {}
  }
}
