# Staff Management — Integration Guide

## 1. Register the routes in your Express app

```ts
// apps/api/src/index.ts (or server.ts)

import express from 'express'
import teamRouter    from './routes/team'
import webhookRouter from './routes/webhooks'

const app = express()

// Webhook MUST use raw body — register BEFORE express.json()
app.use(
  '/webhooks',
  express.raw({ type: 'application/json' }),
  webhookRouter
)

// All other routes use JSON
app.use(express.json())

// Team routes — mounted under /api/v1/team (matches api-routes.md)
app.use('/api/v1/team', teamRouter)
```

---

## 2. Install the Clerk webhook (Clerk Dashboard → Webhooks)

1. Go to **clerk.com** → your app → **Webhooks** → **Add endpoint**
2. URL: `https://api.RentalDriveGo.com/webhooks/clerk`
3. Events to subscribe: `user.created`
4. Copy the **Signing Secret** and add to `.env`:

```env
CLERK_WEBHOOK_SECRET=whsec_xxxxxxxxxxxxxxxxxxxxx
```

5. Install `svix` for signature verification:

```bash
npm install svix
```

---

## 3. Environment variables needed

```env
# Clerk
CLERK_SECRET_KEY=sk_live_...
CLERK_WEBHOOK_SECRET=whsec_...

# Frontend
NEXT_PUBLIC_API_URL=https://api.RentalDriveGo.com/api/v1

# Dashboard URL (used in invite redirect)
DASHBOARD_URL=https://app.RentalDriveGo.com
```

---

## 4. Add the page to the Next.js dashboard app

```
apps/dashboard/
├── app/
│   └── dashboard/
│       └── team/
│           └── page.tsx          ← copy frontend/pages/team.tsx here
├── components/
│   └── team/
│       ├── InviteModal.tsx       ← copy from frontend/components/team/
│       ├── EditMemberModal.tsx
│       └── PermissionsMatrix.tsx
└── hooks/
    └── useTeam.ts                ← copy from frontend/hooks/
```

Add the route to your dashboard sidebar navigation:

```tsx
// components/Sidebar.tsx — add to nav items
{ href: '/dashboard/team', label: 'Team', icon: UsersIcon }
```

---

## 5. requireRole middleware placement

The `requireRole` middleware is already applied inside the team router.
Only expose it if you need it elsewhere (e.g., `PATCH /pricing-rules` → `requireRole('MANAGER')`):

```ts
import { requireRole } from './middleware/requireRole'

// Example: license approval endpoint (OWNER or MANAGER only)
router.post(
  '/customers/:id/approve-license',
  requireRole('MANAGER'),
  approveLicenseHandler
)
```

---

## 6. Invite acceptance flow (frontend)

When a user clicks the magic link in their invitation email, Clerk redirects them to:

```
https://app.RentalDriveGo.com/onboarding/accept-invite?__clerk_ticket=...
```

Create this page in your Next.js app:

```tsx
// app/onboarding/accept-invite/page.tsx
'use client'
import { useEffect } from 'react'
import { useClerk } from '@clerk/nextjs'
import { useRouter } from 'next/navigation'

export default function AcceptInvite() {
  const { handleRedirectCallback } = useClerk()
  const router = useRouter()

  useEffect(() => {
    handleRedirectCallback({}).then(() => {
      // Clerk webhook fires user.created → activates Employee record in DB
      // Redirect to dashboard after a short delay
      setTimeout(() => router.replace('/dashboard'), 1000)
    })
  }, [])

  return (
    <div className="flex items-center justify-center min-h-screen">
      <p className="text-sm text-zinc-500">Setting up your account…</p>
    </div>
  )
}
```

---

## 7. Prisma type extensions (optional, for `req.employee`)

To get TypeScript to recognize `req.companyId` and `req.employee` on Express requests,
add a type declaration file:

```ts
// types/express.d.ts
import { Employee, Company } from '@prisma/client'

declare global {
  namespace Express {
    interface Request {
      companyId: string
      company: Company
      employee: Employee
    }
  }
}
```

---
