A full-stack monorepo template for building SaaS applications with React 19, tRPC, and Cloudflare Workers. Type-safe from database to UI, deployable to the edge in minutes.
## Highlights
- **Type-safe full stack** – TypeScript, tRPC, and Drizzle ORM create a single type contract from database to UI
- **Edge-native** – Three Cloudflare Workers (web, app, api) connected via service bindings
- **Auth + billing included** – Better Auth with email OTP, passkey, Google OAuth, organizations, and Stripe subscriptions
- **Modern React** – React 19, TanStack Router (file-based), TanStack Query, Jotai, Tailwind CSS v4, shadcn/ui
- **Database ready** – Drizzle ORM with Neon PostgreSQL, migrations, and seed data
- **Fast DX** – Bun toolchain, Vite, Vitest, Oxlint, Oxfmt, and pre-configured VS Code settings
React Starter Kit is proudly supported by these amazing sponsors:

Each app deploys independently to Cloudflare Workers. The web worker routes `/api/*` to the API worker and app routes to the app worker via service bindings.
## Prerequisites
- [Bun](https://bun.sh/) v1.4+ (replaces Node.js and npm)
- [VS Code](https://code.visualstudio.com/) with our [recommended extensions](.vscode/extensions.json)
- [React Developer Tools](https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi?hl=en) browser extension (recommended)
- [Cloudflare account](https://dash.cloudflare.com/sign-up) for deployment
## Quick Start
### 1. Create Your Project
[Generate a new repository](https://github.com/kriasoft/react-starter-kit/generate) from this template, then clone it locally:
```bash
git clone https://github.com/your-username/your-project-name.git
cd your-project-name
```
### 2. Install Dependencies
```bash
bun install
```
### 3. Configure Environment
This project follows [Vite env conventions](https://vite.dev/guide/env-and-mode#env-files):
- [`.env`](./.env) is committed and contains shared defaults/placeholders only (no real secrets)
- `.env.local` is git-ignored and should contain your real credentials
- `.env.local` values override `.env`
```bash
cp .env .env.local # then replace placeholder values with real ones
```
Also check [`wrangler.jsonc`](./apps/api/wrangler.jsonc) for Worker configuration and bindings.
### 4. Start Development
```bash
# Launch all apps in development mode (web, api, and app)
bun dev
# Or, start specific apps individually
bun web:dev # Marketing site
bun app:dev # Main application
bun api:dev # API server
```
### 5. Initialize Database
Ensure `DATABASE_URL` is configured in your `.env.local` file, then set up the schema:
```bash
bun db:push # Push schema directly (quick dev setup)
bun db:seed # Seed with sample data (optional)
bun db:studio # Open database GUI
```
`db:push` is for local prototyping only. Staging and production apply migrations instead: `bun db:migrate:staging`, `bun db:migrate:production`.
| App | URL |
| -------------- | ----------------------- |
| React app | |
| Marketing site | |
| API server | |
## Keep Your Project Updated
When you want to bring in newer React Starter Kit changes, ask your coding agent to run the `merge-seed` skill (`/merge-seed` in Claude Code or `$merge-seed` in Codex). It merges upstream changes while preserving your project's identity and configuration. Start with a clean working tree; the [Quick Start guide](https://reactstarter.com/getting-started/quick-start#keep-template-updates) explains the workflow and its safety boundary.
## Production Deployment
The short version. The [deployment guide](https://reactstarter.com/deployment/) covers each step in full.
### 1. Provision Infrastructure
Terraform creates the Hyperdrive configurations the API worker connects through:
```bash
bun infra:production apply
```
Paste the two IDs it prints into the `hyperdrive` block of `apps/api/wrangler.jsonc`.
### 2. Environment Setup
Configure your production secrets in Cloudflare Workers:
```bash
# Required – the API refuses to deploy without these
bun wrangler secret put BETTER_AUTH_SECRET --config apps/api/wrangler.jsonc --env=""
bun wrangler secret put RESEND_API_KEY --config apps/api/wrangler.jsonc --env=""
# Google sign-in (optional – email OTP and passkeys work without it)
bun wrangler secret put GOOGLE_CLIENT_ID --config apps/api/wrangler.jsonc --env=""
bun wrangler secret put GOOGLE_CLIENT_SECRET --config apps/api/wrangler.jsonc --env=""
# Stripe billing (optional – set all four to enable, or none; annual is extra)
bun wrangler secret put STRIPE_SECRET_KEY --config apps/api/wrangler.jsonc --env=""
bun wrangler secret put STRIPE_WEBHOOK_SECRET --config apps/api/wrangler.jsonc --env=""
bun wrangler secret put STRIPE_STARTER_PRICE_ID --config apps/api/wrangler.jsonc --env=""
bun wrangler secret put STRIPE_PRO_PRICE_ID --config apps/api/wrangler.jsonc --env=""
bun wrangler secret put STRIPE_PRO_ANNUAL_PRICE_ID --config apps/api/wrangler.jsonc --env="" # optional
```
All of these belong to the API worker, which is what `--config` selects – without it Wrangler has no worker to attach the secret to. Use `--env staging` for staging; production is the top-level config, selected explicitly with `--env=""`. Non-sensitive vars like `RESEND_EMAIL_FROM` go in `wrangler.jsonc` directly.
Set `RESEND_EMAIL_FROM` to an address on a domain you have verified with Resend. The default `onboarding@resend.dev` only delivers to your own inbox, and sign-in is email OTP – leave it and no one else can sign in.
### 3. Migrate the Production Database
```bash
bun db:migrate:production # reads .env.production.local, and only that file
```
### 4. Build and Deploy
```bash
# Builds, then deploys api -> app -> web (service-binding targets first)
bun deploy:staging
bun deploy:production
```
CI runs the same script, so a release from your machine and one from GitHub Actions cannot drift.
