Slice 1: Multi-Tenant Foundation

Admin Creates Vendor → Vendor Owner Logs In

Status: 🔄 IN PROGRESS
Timeline: Week 1 (5 days)
Current Progress: Backend ~90%, Frontend ~60%

🎯 Slice Objectives

Establish the multi-tenant foundation with complete vendor isolation and admin capabilities.

User Stories

• ✅ As a Super Admin, I can create vendors through the admin interface
• As a Super Admin, I can manage vendor accounts (verify, activate, deactivate)
• ✅ As a Vendor Owner, I can log into my vendor-specific admin interface
• ✅ The system correctly isolates vendor contexts (subdomain + path-based)

Success Criteria

• ✅ Admin can log into admin interface
• ✅ Admin can create new vendors with auto-generated owner accounts
• ✅ System generates secure temporary passwords
• ✅ Vendor owner can log into vendor-specific interface
• Vendor context detection works in dev (path) and prod (subdomain) modes
• Database properly isolates vendor data
• All API endpoints protected with JWT authentication
• ✅ Frontend integrates seamlessly with backend

✅ Testing Checklist

Backend Tests

Authentication

• Admin can login with valid credentials
• Admin login rejects invalid credentials
• Non-admin users cannot access admin endpoints
• JWT tokens expire after configured time
• Token refresh works correctly

Vendor Management

• Admin can create vendor with all required fields
• System generates unique vendor code
• System generates unique subdomain
• Owner user account is created automatically
• Temporary password is generated (12+ characters)
• Default roles are created (Owner, Manager, Editor, Viewer)
• Owner is linked to Owner role
• Vendor is auto-verified when created by admin
• Duplicate vendor code is rejected
• Duplicate subdomain is rejected
• Duplicate owner email is rejected

Vendor Context Detection

• Subdomain detection works: vendor.platform.com
• Path detection works: /vendor/VENDORCODE/
• Admin routes bypass vendor context
• API routes bypass vendor context
• Static routes bypass vendor context
• Invalid vendor returns appropriate error

API Endpoints

• POST /api/v1/admin/vendors creates vendor
• GET /api/v1/admin/vendors lists vendors with pagination
• GET /api/v1/admin/dashboard returns statistics
• PUT /api/v1/admin/vendors/{id}/verify toggles verification
• PUT /api/v1/admin/vendors/{id}/status toggles active status
• All endpoints require admin authentication
• All endpoints return proper error messages

Frontend Tests

Admin Login Page

• Page loads without errors
• Form validation works
• Loading state displays during login
• Error messages display correctly
• Successful login redirects to dashboard
• Token is stored in localStorage
• Page is responsive on mobile

Admin Dashboard

• Dashboard loads with statistics
• Vendor count is accurate
• User count is accurate
• Recent vendors list displays
• Navigation works correctly
• Refresh button updates data
• Loading states work correctly
• No console errors

Vendor Creation Page

• Form loads correctly
• All fields are validated
• Vendor code auto-uppercases
• Subdomain auto-lowercases
• Email validation works
• Submit creates vendor successfully
• Credentials are displayed once
• Can copy credentials
• Form resets after creation
• Error messages display correctly

Vendor Login Page

• Page loads with vendor context
• Vendor name displays correctly

• Login fails with wrong credentials
• Redirects to vendor dashboard
• Token stored in localStorage
• "Vendor Not Found" shows for invalid vendor

Vendor Dashboard

• Dashboard loads successfully
• Vendor information displays
• Statistics load correctly
• Welcome message shows
• Verification badge shows correct status
• No console errors

Database Tests

Schema Verification

-- Check tables exist
SELECT table_name FROM information_schema.tables 
WHERE table_schema = 'public';
-- Expected: users, vendors, roles, vendor_users

-- Check admin user
SELECT * FROM users WHERE role = 'admin';

-- Check vendor creation
SELECT * FROM vendors WHERE vendor_code = 'TESTVENDOR';

-- Check owner user
SELECT * FROM users WHERE email = 'owner@testvendor.com';

-- Check default roles
SELECT * FROM roles WHERE vendor_id = (
    SELECT id FROM vendors WHERE vendor_code = 'TESTVENDOR'
);
-- Expected: 4 roles (Owner, Manager, Editor, Viewer)

Security Tests

• Passwords are hashed with bcrypt
• JWT tokens are properly signed
• Admin endpoints reject non-admin users
• Vendor endpoints require authentication
• Cross-vendor access is prevented
• SQL injection is prevented
• XSS is prevented in forms
• CSRF protection is enabled

Performance Tests

• Admin login responds < 1 second
• Dashboard loads < 2 seconds
• Vendor creation completes < 3 seconds
• Vendor list loads < 1 second
• No N+1 query problems

📝 Documentation Tasks

4. Document Learnings: Update this document with lessons learned
5. Move to Slice 2: Begin marketplace import implementation

💡 Tips & Best Practices

Working with Alpine.js

• Keep components focused and small
• Use x-data for reactive state
• Use x-init for loading data
• Prefer x-show over x-if for toggles
• Use @click, @submit for event handling

Working with Jinja2

• Pass initial data from backend to avoid extra API calls
• Use template inheritance (extends, blocks)
• Keep logic in backend, not templates
• Use filters for formatting

API Integration

• Always handle loading states
• Always handle errors gracefully
• Use the shared apiClient utility
• Store tokens in localStorage
• Clear tokens on logout
