# Auth Routes Refactor Summary

## Overview

Refactored authentication routes to delegate fully to WorkOS AuthKit hosted UI, removing custom login/register forms in favor of automatic redirects.

## Changes Made

### 1. Updated `/auth/login` Route

**File:** `/Users/kooshapari/temp-PRODVERCEL/485/kush/trace/frontend/apps/web/src/routes/auth.login.tsx`

**Before:**

- Custom UI with WorkOS branding
- "Sign In with WorkOS" button requiring user click
- Multiple UI elements (title, description, card, button)

**After:**

- Minimal redirect handler
- Automatic redirect to WorkOS hosted UI via `signIn()`
- Only shows "Redirecting to sign in..." loading message
- No user interaction required

**Key Changes:**

```typescript
// Removed custom UI components (Button, cards, etc.)
// Added automatic redirect logic in useEffect
useEffect(() => {
  if (user && !isLoading) {
    navigate({ to: '/' }); // Already authenticated
    return;
  }
  if (!isLoading && !user) {
    signIn(); // Immediate redirect to WorkOS
  }
}, [user, isLoading, signIn, navigate]);
```

### 2. Updated `/auth/register` Route

**File:** `/Users/kooshapari/temp-PRODVERCEL/485/kush/trace/frontend/apps/web/src/routes/auth.register.tsx`

**Before:**

- Custom UI with sign-up messaging
- "Sign Up with WorkOS" button
- Link to switch between login/register
- Multiple UI elements

**After:**

- Minimal redirect handler
- Automatic redirect to WorkOS hosted UI via `signUp()`
- Only shows "Redirecting to sign up..." loading message
- No user interaction required

**Key Changes:**

```typescript
// Removed custom UI components
// Added automatic redirect logic in useEffect
useEffect(() => {
  if (user && !isLoading) {
    navigate({ to: '/' }); // Already authenticated
    return;
  }
  if (!isLoading && !user) {
    signUp(); // Immediate redirect to WorkOS
  }
}, [user, isLoading, signUp, navigate]);
```

### 3. Fixed AuthKitProvider Configuration

**File:** `/Users/kooshapari/temp-PRODVERCEL/485/kush/trace/frontend/apps/web/src/providers/AppProviders.tsx`

**Before:**

```typescript
providerProps.redirectUri = `${window.location.origin}/`;
```

**After:**

```typescript
providerProps.redirectUri = `${window.location.origin}/auth/callback`;
```

**Reason:** The `redirectUri` must point to the OAuth callback route (`/auth/callback`) that handles the authentication response from WorkOS, not the root path.

### 4. Unchanged Routes (Kept As-Is)

#### `/auth/callback`

**File:** `/Users/kooshapari/temp-PRODVERCEL/485/kush/trace/frontend/apps/web/src/routes/auth.callback.tsx`

- Already properly implemented
- Handles OAuth callback from WorkOS
- Processes authentication state
- Redirects to intended destination

#### `/auth/logout`

**File:** `/Users/kooshapari/temp-PRODVERCEL/485/kush/trace/frontend/apps/web/src/routes/auth.logout.tsx`

- Already properly implemented
- Clears auth state
- Signs out from WorkOS
- Redirects to login

## Authentication Flow

### Login Flow

1. User navigates to `/auth/login`
2. `LoginRedirect` component mounts
3. Checks if user already authenticated → redirect to dashboard
4. If not authenticated → immediately calls `signIn()`
5. `signIn()` redirects browser to WorkOS hosted UI
6. User authenticates on WorkOS
7. WorkOS redirects to `/auth/callback`
8. Callback handler processes OAuth response
9. User redirected to dashboard (or returnTo URL)

### Register Flow

1. User navigates to `/auth/register`
2. `RegisterRedirect` component mounts
3. Checks if user already authenticated → redirect to dashboard
4. If not authenticated → immediately calls `signUp()`
5. `signUp()` redirects browser to WorkOS hosted UI (registration mode)
6. User creates account on WorkOS
7. WorkOS redirects to `/auth/callback`
8. Callback handler processes OAuth response
9. User redirected to dashboard (or returnTo URL)

## Benefits

### 1. Simpler Codebase

- Removed ~60 lines of custom UI code from each route
- No need to maintain custom login/register forms
- Single source of truth for auth UI (WorkOS)

### 2. Better User Experience

- Consistent auth experience across WorkOS products
- Professional, well-tested auth UI
- Automatic redirect - no extra click required
- Better mobile experience (WorkOS UI is mobile-optimized)

### 3. Security

- All auth UI handled by WorkOS (security experts)
- No custom auth forms to maintain/secure
- Reduces attack surface area

### 4. Maintainability

- Less code to maintain
- Auth UI updates automatically from WorkOS
- Easier to add new auth features (SSO, MFA, etc.)

## Configuration Requirements

### WorkOS Dashboard

Ensure the following redirect URI is configured in your WorkOS Dashboard:

```
http://localhost:5173/auth/callback  (development)
https://yourdomain.com/auth/callback (production)
```

### Environment Variables

```bash
VITE_WORKOS_CLIENT_ID=your_client_id_here
```

## Testing Checklist

- [ ] Navigate to `/auth/login` → should redirect to WorkOS
- [ ] Navigate to `/auth/register` → should redirect to WorkOS
- [ ] Complete login flow → should return to dashboard
- [ ] Complete register flow → should return to dashboard
- [ ] Visit `/auth/login` when already logged in → should redirect to dashboard
- [ ] Logout → should clear session and redirect to login
- [ ] Test with `returnTo` parameter → should redirect to intended page after auth

## Migration Notes

### Breaking Changes

None - the routes maintain the same URLs and behavior, just with automatic redirects instead of manual button clicks.

### Removed Dependencies

- No longer importing `Button` from `@tracertm/ui` in auth routes
- No longer importing `LogIn`, `UserPlus` icons from `lucide-react`
- Removed `AUTH_ROUTES` import from register route (no longer needed)

### Added Logic

- Automatic redirect logic in `useEffect` hooks
- Proper loading state handling to prevent redirect loops

## Reference Documentation

- [WorkOS AuthKit React Docs](https://workos.com/docs/authkit/react/python)
- [WorkOS AuthKit Provider Config](https://workos.com/docs/authkit/react/configuration)
- Internal: `/auth/callback` documentation in codebase

## Files Modified

1. `/Users/kooshapari/temp-PRODVERCEL/485/kush/trace/frontend/apps/web/src/routes/auth.login.tsx`
2. `/Users/kooshapari/temp-PRODVERCEL/485/kush/trace/frontend/apps/web/src/routes/auth.register.tsx`
3. `/Users/kooshapari/temp-PRODVERCEL/485/kush/trace/frontend/apps/web/src/providers/AppProviders.tsx`

## Verification

To verify the changes work correctly:

```bash
# Start the dev server
bun run dev

# Visit http://localhost:5173/auth/login
# Should immediately redirect to WorkOS hosted UI

# Visit http://localhost:5173/auth/register
# Should immediately redirect to WorkOS hosted UI (registration mode)
```

## Next Steps

1. Test the auth flow end-to-end
2. Verify WorkOS Dashboard has correct redirect URIs
3. Update any documentation that references the old custom login UI
4. Consider removing unused UI component imports if not used elsewhere
