Build TanStack Start apps with the Cloudflare Vite plugin

Workers

The Cloudflare Vite plugin now supports TanStack Start ↗ apps. Get started with new or existing projects.

New projects

Create a new TanStack Start project that uses the Cloudflare Vite plugin via the create-cloudflare CLI:

npm create cloudflare@latest -- my-tanstack-start-app --framework=tanstack-start

Existing projects

Migrate an existing TanStack Start project to use the Cloudflare Vite plugin:

  1. Install @cloudflare/vite-plugin and wrangler
npm i -D @cloudflare/vite-plugin wrangler
  1. Add the Cloudflare plugin to your Vite config
vite.config.ts
import { defineConfig } from "vite";
import { tanstackStart } from "@tanstack/react-start/plugin/vite";
import viteReact from "@vitejs/plugin-react";
import { cloudflare } from "@cloudflare/vite-plugin";


export default defineConfig({
  plugins: [
    cloudflare({ viteEnvironment: { name: "ssr" } }),
    tanstackStart(),
    viteReact(),
  ],
});
  1. Add your Worker config file
JSONC
{
  "$schema": "./node_modules/wrangler/config-schema.json",
  "name": "my-tanstack-start-app",
  // Set this to today's date
  "compatibility_date": "2026-04-14",
  "compatibility_flags": [
    "nodejs_compat"
  ],
  "main": "@tanstack/react-start/server-entry"
}
  1. Modify the scripts in your package.json
package.json
{
  "scripts": {
    "dev": "vite dev",
    "build": "vite build && tsc --noEmit",
    "start": "node .output/server/index.mjs",
    "preview": "vite preview",
    "deploy": "npm run build && wrangler deploy",
    "cf-typegen": "wrangler types"
  }
}
