Build a full-stack TanStack Start app on Cloudflare Workers from scratch — SSR, file-based routing, server functions, D1+Drizzle, better-auth, Tailwind v4+shadcn/ui. Use whenever the user mentions TanStack Start, asks to scaffold a full-stack Cloudflare app with SSR, wants an SSR
Overview
Build a full-stack TanStack Start app on Cloudflare Workers from scratch — SSR, file-based routing, server functions, D1+Drizzle, better-auth, Tailwind v4+shadcn/ui. Use whenever the user mentions TanStack Start, asks to scaffold a full-stack Cloudflare app with SSR, wants an SSR dashboard, or asks for a React 19 + Cloudflare Workers app with file-based routing and server functions — even if they don't name TanStack Start specifically. No template repo — Claude generates every file fresh per project.

Workflow
Step 1: Gather Project Info
| Required | Optional |
|---|---|
| Project name (kebab-case) | Google OAuth credentials |
| One-line description | Custom domain |
| Cloudflare account | R2 storage needed? |
| Auth method: Google OAuth, email/password, or both | Admin email |
Step 2: Initialise Project
Create the project directory and all config files from scratch.
vite.config.ts — Plugin order matters. Cloudflare MUST be first:
import { defineConfig } from "vite";
import { cloudflare } from "@cloudflare/vite-plugin";
import { tanstackStart } from "@tanstack/react-start/plugin/vite";
import tailwindcss from "@tailwindcss/vite";
import viteReact from "@vitejs/plugin-react";
export default defineConfig({
plugins: [
cloudflare({ viteEnvironment: { name: "ssr" } }),
tailwindcss(),
tanstackStart(),
viteReact(),
],
});
wrangler.jsonc:
{
"$schema": "node_modules/wrangler/config-schema.json",
"name": "PROJECT_NAME",
"compatibility_date": "2025-04-01",
"compatibility_flags": ["nodejs_compat"],
"main": "@tanstack/react-start/server-entry",
"account_id": "ACCOUNT_ID",
"d1_databases": [
{
"binding": "DB",
"database_name": "PROJECT_NAME-db",
"database_id": "DATABASE_ID",
"migrations_dir": "drizzle"
}
]
}
Key points: main MUST be "@tanstack/react-start/server-entry" (Nitro server entry). Use nodejs_compat (NOT node_compat). Add account_id to avoid interactive prompts.
tsconfig.json:
{
"compilerOptions": {
"target": "ES2022",
"module": "ESNext",
"moduleResolution": "bundler",
"jsx": "react-jsx",
"strict": true,
"skipLibCheck": true,
"esModuleInterop": true,
"resolveJsonModule": true,
"isolatedModules": true,
"noEmit": true,
"paths": { "@/*": ["./src/*"] },
"types": ["@cloudflare/workers-types/2023-07-01"]
},
"include": ["src/**/*", "vite.config.ts"]
}
.dev.vars — generate BETTER_AUTH_SECRET with openssl rand -hex 32:
BETTER_AUTH_SECRET=<generated-hex-32>
BETTER_AUTH_URL=http://localhost:3000
TRUSTED_ORIGINS=http://localhost:3000
# GOOGLE_CLIENT_ID=
# GOOGLE_CLIENT_SECRET=
.gitignore — node_modules, .wrangler, dist, .output, .dev.vars, .vinxi, .DS_Store
Then install and create the D1 database:
cd PROJECT_NAME && pnpm install
npx wrangler d1 create PROJECT_NAME-db
# Copy the database_id into wrangler.jsonc d1_databases binding
Step 3: Database Schema
src/db/schema.ts — All tables. better-auth requires: users, sessions, accounts, verifications. Add application tables (e.g. items) for CRUD demo.
D1-specific rules:
- Use
integerfor timestamps (Unix epoch), NOT Date objects - Use
textfor primary keys (nanoid/cuid2), NOT autoincrement - Keep bound parameters under 100 per query (batch large inserts)
- Foreign keys are always ON in D1
src/db/index.ts — Drizzle client factory:
import { drizzle } from "drizzle-orm/d1";
import { env } from "cloudflare:workers";
import * as schema from "./schema";
export function getDb() {
return drizzle(env.DB, { schema });
}
CRITICAL: Use import { env } from "cloudflare:workers" — NOT process.env. Create the Drizzle client inside each server function (per-request), not at module level.
drizzle.config.ts:
import { defineConfig } from "drizzle-kit";
export default defineConfig({
schema: "./src/db/schema.ts",
out: "./drizzle",
dialect: "sqlite",
});
Generate and apply the initial migration:
pnpm db:generate
pnpm db:migrate:local
Step 4: Configure Auth
src/lib/auth.server.ts — Server-side better-auth:
import { betterAuth } from "better-auth";
import { drizzleAdapter } from "better-auth/adapters/drizzle";
import { drizzle } from "drizzle-orm/d1";
import { env } from "cloudflare:workers";
import * as schema from "../db/schema";
export function getAuth() {
const db = drizzle(env.DB, { schema });
return betterAuth({
database: drizzleAdapter(db, { provider: "sqlite" }),
secret: env.BETTER_AUTH_SECRET,
baseURL: env.BETTER_AUTH_URL,
trustedOrigins: env.TRUSTED_ORIGINS?.split(",") ?? [],
emailAndPassword: { enabled: true },
socialProviders: {
// Add Google OAuth if credentials provided
},
});
}
CRITICAL: getAuth() must be called per-request (inside handler/loader), NOT at module level.
src/lib/auth.client.ts — Client-side auth hooks:
import { createAuthClient } from "better-auth/react";
export const { useSession, signIn, signOut, signUp } = createAuthClient();
src/routes/api/auth/$.ts — API catch-all for better-auth:
import { createAPIFileRoute } from "@tanstack/react-start/api";
import { getAuth } from "../../../lib/auth.server";
export const APIRoute = createAPIFileRoute("/api/auth/$")({
GET: ({ request }) => getAuth().handler(request),
POST: ({ request }) => getAuth().handler(request),
});
CRITICAL: Auth MUST use an API route (createAPIFileRoute), NOT a server function (createServerFn). better-auth needs direct request/response access.
Step 5: Server Functions
Core pattern — always create DB client inside the handler:
import { createServerFn } from "@tanstack/react-start";
import { getDb } from "../db";
export const getItems = createServerFn({ method: "GET" }).handler(async () => {
const db = getDb();
return db.select().from(items).all();
});
Input validation with Zod:
export const createItem = createServerFn({ method: "POST" })
.inputValidator(
z.object({
name: z.string().min(1),
description: z.string().optional(),
})
)
.handler(async ({ data }) => {
const db = getDb();
const id = crypto.randomUUID();
await db.insert(items).values({ id, ...data, createdAt: Date.now() });
return { id };
});
Protected server functions — check auth, throw redirect if unauthenticated:
import { redirect } from "@tanstack/react-router";
import { getAuth } from "../lib/auth.server";
async function requireSession(request?: Request) {
const auth = getAuth();
const session = await auth.api.getSession({
headers: request?.headers ?? new Headers(),
});
if (!session) {
throw redirect({ to: "/login" });
}
return session;
}
export const getSessionFn = createServerFn({ method: "GET" }).handler(
async ({ request }) => {
const auth = getAuth();
return auth.api.getSession({ headers: request.headers });
}
);
export const getItems = createServerFn({ method: "GET" }).handler(
async ({ request }) => {
const session = await requireSession(request);
const db = getDb();
return db.select().from(items).where(eq(items.userId, session.user.id)).all();
}
);
Route loader pattern — server functions in route loader:
export const Route = createFileRoute("/_authed/items")({
loader: () => getItems(),
component: ItemsPage,
});
function ItemsPage() {
const items = Route.useLoaderData();
return <div>{items.map((item) => <div key={item.id}>{item.name}</div>)}</div>;
}
Auth guard (_authed.tsx) — use beforeLoad:
export const Route = createFileRoute("/_authed")({
beforeLoad: async () => {
const session = await getSessionFn();
if (!session) {
throw redirect({ to: "/login" });
}
return { session };
},
});
Child routes access session via Route.useRouteContext().
Mutation + invalidation — after mutations, invalidate router to refetch loaders:
function CreateItemForm() {
const router = useRouter();
const handleSubmit = async (data: NewItem) => {
await createItem({ data });
router.invalidate();
router.navigate({ to: "/items" });
};
return <form onSubm

### Step 2: Initialise Project
Create the project directory and all config files from scratch.
**`vite.config.ts`** — Plugin order matters. Cloudflare MUST be first:
```typescript
import { defineConfig } from "vite";

}
```
Key points: `main` MUST be `"@tanstack/react-start/server-entry"` (Nitro server entry). Use `nodejs_compat` (NOT `node_compat`). Add `account_id` to avoid interactive prompts.
**`tsconfig.json`**:
```json

"include": ["src/**/*", "vite.config.ts"]
}
```
**`.dev.vars`** — generate `BETTER_AUTH_SECRET` with `openssl rand -hex 32`:

BETTER_AUTH_SECRET=<generated-hex-32>
BETTER_AUTH_URL=http://localhost:3000
TRUSTED_ORIGINS=http://localhost:3000

**`.gitignore`** — node_modules, .wrangler, dist, .output, .dev.vars, .vinxi, .DS_Store
Then install and create the D1 database:

import { env } from "cloudflare:workers";
import * as schema from "../db/schema";
export function getAuth() {

**CRITICAL**: `getAuth()` must be called per-request (inside handler/loader), NOT at module level.
**`src/lib/auth.client.ts`** — Client-side auth hooks:

```
**`src/routes/api/auth/$.ts`** — API catch-all for better-auth:
```typescript
import { createAPIFileRoute } from "@tanstack/react-start/api";
