Architecture ​

examples/monorepo/
├── server/    Express + Prisma + @authcore/express with useCookies (port 3000)
└── client/    Vite + React + @authcore/react mode="cookie" (port 5173)
  • Vite dev server proxies /auth and /api to backend
  • In production, Express serves the built client SPA
  • Auth uses httpOnly cookies — no token in localStorage

Setup ​

bash
cd examples/monorepo
cp .env.example .env

cd server && pnpm install && pnpm db:push && cd ..
cd client && pnpm install && cd ..

Run in two terminals:

bash
pnpm dev:server    # Express on :3000
pnpm dev:client    # Vite on :5173 with proxy

Key Code ​

Server — cookie-based auth:

ts
app.use('/auth', auth.router({ useCookies: true }))

Client — cookie mode (no token management needed):

tsx
<AuthProvider baseUrl="/auth" mode="cookie">
  <AppContent />
</AuthProvider>

Vite proxy — routes auth requests to backend during dev:

ts
server: {
  proxy: {
    '/auth': 'http://localhost:3000',
    '/api': 'http://localhost:3000',
  },
}
