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 runtime, Vite, Vitest, ESLint, Prettier, 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 v1.3+ (replaces Node.js and npm)
• VS Code with our recommended extensions
• React Developer Tools browser extension (recommended)
• Cloudflare account for deployment

Quick Start

1. Create Your Project

Generate a new repository from this template, then clone it locally:

git clone https://github.com/your-username/your-project-name.git
cd your-project-name

2. Install Dependencies

bun install

3. Configure Environment

This project follows Vite env conventions:

• .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

cp .env .env.local  # then replace placeholder values with real ones

Also check wrangler.jsonc for Worker configuration and bindings.

4. Start Development

# 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:

bun db:push              # Push schema directly (quick dev setup)
bun db:seed              # Seed with sample data (optional)
bun db:studio            # Open database GUI

For production, use bun db:migrate to apply migrations instead of db:push.

App	URL
React app	http://localhost:5173
Marketing site	http://localhost:4321
API server	http://localhost:8787

Production Deployment

1. Environment Setup

Configure your production secrets in Cloudflare Workers:

# Required secrets
bun wrangler secret put BETTER_AUTH_SECRET

# Stripe billing (optional — first 4 required to enable, annual is optional)
bun wrangler secret put STRIPE_SECRET_KEY
bun wrangler secret put STRIPE_WEBHOOK_SECRET
bun wrangler secret put STRIPE_STARTER_PRICE_ID
bun wrangler secret put STRIPE_PRO_PRICE_ID
bun wrangler secret put STRIPE_PRO_ANNUAL_PRICE_ID  # optional

# OAuth providers (as needed)
bun wrangler secret put GOOGLE_CLIENT_ID
bun wrangler secret put GOOGLE_CLIENT_SECRET

# Email service
bun wrangler secret put RESEND_API_KEY

# AI features (optional)
bun wrangler secret put OPENAI_API_KEY

Run these commands from the target app directory or pass --config apps/<app>/wrangler.jsonc. Non-sensitive vars like RESEND_EMAIL_FROM go in wrangler.jsonc directly.

2. Build and Deploy

# Build packages that require compilation (order matters!)
bun email:build    # Build email templates first
bun web:build      # Build marketing site
bun app:build      # Build main React app

# Deploy all applications
bun web:deploy     # Deploy marketing site
bun api:deploy     # Deploy API server
bun app:deploy     # Deploy main React app
