Tech Stack

Layer	Technology
Platform	Cloudflare Workers with Static Assets
Frontend	React 19 + Vite

Quick Start

1. Clone and Install

git clone https://github.com/jezweb/vite-flare-starter.git my-app
cd my-app
pnpm install

2. Create Cloudflare Resources

# Login to Cloudflare
pnpm cf:login

# Create D1 database
npx wrangler d1 create vite-flare-starter-db
# Copy the database_id to wrangler.jsonc

# Create R2 bucket for avatars
npx wrangler r2 bucket create vite-flare-starter-avatars

3. Configure Environment

# Copy example env file
cp .dev.vars.example .dev.vars

# Edit .dev.vars with your values:
# - BETTER_AUTH_SECRET (generate with: openssl rand -hex 32)
# - BETTER_AUTH_URL (http://localhost:5173 for local)
# - Optional: Google OAuth credentials

4. Generate and Apply Migrations

# Generate migration from schema
pnpm db:generate:named "initial_schema"

# Apply migration locally
pnpm db:migrate:local

5. Start Development

pnpm dev
# Open http://localhost:5173

6. Deploy to Production

# Apply migration to remote database
pnpm db:migrate:remote

# Set production secrets
echo "your-secret" | npx wrangler secret put BETTER_AUTH_SECRET
echo "https://your-app.workers.dev" | npx wrangler secret put BETTER_AUTH_URL

# Deploy
pnpm deploy

Production Checklist

Before deploying to a new domain, ensure:

1. Set TRUSTED_ORIGINS to include your production domain(s):

   echo "http://localhost:5173,https://your-app.workers.dev" | npx wrangler secret put TRUSTED_ORIGINS

2. Set BETTER_AUTH_URL secret to your exact production URL:

   echo "https://your-app.workers.dev" | npx wrangler secret put BETTER_AUTH_URL

3. For Google OAuth, add redirect URI in Google Cloud Console:

   https://your-app.workers.dev/api/auth/callback/google
   

Common issues:

• Auth works but redirects to homepage → Check TRUSTED_ORIGINS includes your domain
• OAuth callback fails → Check BETTER_AUTH_URL matches your domain exactly
• Google sign-in fails → Check redirect URI is registered in Google Cloud Console

Adding a New Module

1. Create Backend - Add routes in src/server/modules/your-module/
2. Create Schema - Add Drizzle table in src/server/modules/your-module/db/schema.ts
3. Export Schema - Add export to src/server/db/schema.ts
4. Generate Migration - Run pnpm db:generate:named "add_your_table"
5. Register Routes - Mount in src/server/index.ts
6. Create Frontend - Add pages/hooks/components in src/client/modules/your-module/
7. Add Route - Update src/client/App.tsx

Configuration

Disable Email Signup

Set DISABLE_EMAIL_SIGNUP=true to prevent new email/password registrations:

# .dev.vars (local)
DISABLE_EMAIL_SIGNUP=true

# Production
echo "true" | npx wrangler secret put DISABLE_EMAIL_SIGNUP

Note: This only affects email/password signup:

• Existing email users can still log in
• Google OAuth is NOT affected (domain restriction is handled at Google Cloud level)

Google OAuth

1. Create OAuth credentials at Google Cloud Console
2. Set authorized redirect URI: https://your-app.workers.dev/api/auth/callback/google
3. Add credentials to .dev.vars and production secrets

Domain Restriction: To allow only your Google Workspace domain:

• Go to OAuth consent screen → Set "User type" to Internal
• Only users from your domain can sign in (e.g., @yourcompany.com)

Custom Themes

The starter includes 8 built-in color themes plus support for custom themes.

Using Theme Generators:

1. Visit a theme generator:
   • tweakcn - Modern editor with OKLch support
   • shadcn/ui Themes - Official hand-picked themes
   • 10000+ Themes - Browse community themes
2. Copy the generated CSS
3. Go to Settings → Color Theme → Custom
4. Paste the CSS and click "Apply Theme"

Using Claude Code:

Ask Claude Code to generate a theme based on your brand:

Create a custom theme for my app using brand colors:
- Primary: #2563eb (blue)
- Make it professional and clean

Claude will generate the CSS variables which you can paste into the Custom Theme dialog.

Theme CSS Format:

:root {
  --background: 0 0% 100%;
  --foreground: 240 10% 3.9%;
  --primary: 220 90% 56%;
  /* ... other variables */
}

.dark {
  --background: 240 10% 3.9%;
  /* ... dark mode variables */
}

App Branding

Customize the app name displayed in the sidebar:

# .dev.vars (local)
VITE_APP_NAME=My Client App

# Production (in wrangler.jsonc vars or secrets)

Default Theme

Set the default color theme for new users:

# .dev.vars (local)
VITE_DEFAULT_THEME=blue   # Options: default, blue, green, orange, red, rose, violet, yellow

Or edit src/shared/schemas/preferences.schema.ts directly for additional control.

Lock Theme for Client Sites

To prevent users from changing the color theme (useful for branded client sites):

# .dev.vars (local)
VITE_FEATURE_THEME_PICKER=false

Note: Users can still switch between light/dark/system mode - only the color theme picker is hidden.

Hide API Tokens

To hide the API Tokens tab from regular users (power user feature):

# .dev.vars (local)
VITE_FEATURE_API_TOKENS=false

Trusted Origins (Auth)

Configure allowed origins for authentication (required for production):

# .dev.vars (local) - comma-separated list
TRUSTED_ORIGINS=http://localhost:5173,https://myapp.workers.dev,https://myapp.com

Note: http://localhost:5173 is always included automatically for development.

Security Features

Rate Limiting

Sensitive endpoints are rate-limited to prevent abuse:

Endpoint	Limit	Window
Password change	3	24 hours
Email change	5	24 hours
Account deletion	1	24 hours
Avatar upload	10	1 hour
API token creation	10	24 hours

Rate limit constants can be configured in src/shared/config/constants.ts.

Note: Rate limiting uses in-memory storage per worker instance. For distributed rate limiting across workers, consider upgrading to KV storage.

Security Headers

All responses include security headers:

• X-Content-Type-Options: nosniff
• X-Frame-Options: DENY
• Referrer-Policy: strict-origin-when-cross-origin
• Permissions-Policy: camera=(), microphone=(), geolocation=()
• HSTS in production

Password Reset

Users can reset their password via email. Requires email configuration:

# .dev.vars
EMAIL_API_KEY=re_xxxxx          # Resend API key
EMAIL_FROM=noreply@yourdomain.com

The flow:

1. User visits /forgot-password
2. Enter email → reset link sent
3. Click link → /reset-password?token=xxx
4. Set new password → redirect to sign-in

Session Management

Users can view and revoke active sessions at Settings → Sessions:

• View all logged-in devices/browsers
• See IP address and last active time
• Revoke individual sessions
• "Log out everywhere" to revoke all other sessions

Development

Testing

Run tests with Vitest:

pnpm test           # Run tests once
pnpm test:watch     # Watch mode

Tests use @cloudflare/vitest-pool-workers to run against Miniflare for realistic D1/R2 simulation.

Database Seeding

Populate development data:

pnpm db:seed

Creates test users:

• test@example.com / password123
• admin@example.com / admin12345

Plus sample API tokens and organization settings.

API Client

A centralized API client is available at src/client/lib/api-client.ts:

import { apiClient } from '@/client/lib/api-client'

// Type-safe requests with automatic credentials
const data = await apiClient.get<User>('/api/user')
const result = await apiClient.post<Result>('/api/items', { name: 'New Item' })
