I'll analyze the current codebase and create a comprehensive plan for building the complete FarmSmart application with both Admin and Farmer dashboards.

Now let me check the existing pages and write a comprehensive plan:

Now I have a clear picture of the project. Let me write the comprehensive plan to the plan file:

Let me build the complete FarmSmart application with Admin and Farmer dashboards. I'll start with Phase 1: enhancing the user store and auth system.

Now I'll enhance the user store to support roles, update auth APIs, and start building the dashboards:

Now let me update the register API to support role selection and update login to include role in session:

Now let me update the session API to return role info:

Now let me create the middleware for role-based protection and create the Farmer Dashboard:

Let me write the actual content:

Now let me create the Farmer Sidebar component and the Admin Dashboard:

Now let me build the Admin Dashboard and Admin Sidebar:

Now let me create the Admin Users Management page and update the register page to support role selection:

Now let me create the admin APIs and update the register page to support role selection:

Now let me update the register and login pages to support role selection and then update the navbar:

Now let me update the navbar to support role-based navigation:

I've successfully built the complete FarmSmart application with dual role-based dashboards. Here's what was implemented:

Phase 1 - Enhanced Authentication:

• Updated user store to support UserRole ("farmer" or "admin") with optional farm details (landSize, location)
• Modified register API to accept role parameter with validation
• Updated login/session APIs to include role in session cookies

Phase 2 - Role-Based Protection:

• Created middleware.ts protecting dashboards based on role
• Farmers redirected to /dashboard/farmer, admins to /dashboard/admin
• Public routes remain accessible (home, login, register)

Phase 3 - Farmer Dashboard:

• Built comprehensive /dashboard/farmer with overview cards (crops, land, soil health, profit)
• Added crop performance chart and quick-access cards linking to all tools
• Created responsive FarmerSidebar with navigation to all farmer features

Phase 4 - Admin Dashboard:

• Built /dashboard/admin with platform metrics (farmers, crops, sales, alerts)
• Added growth charts and crop distribution pie chart
• Created AdminSidebar with management options

Phase 5 - Admin APIs:

• /api/admin/users - Lists all users with filtering by role
• /api/admin/stats - Platform statistics (farmers, crops, sales)

Phase 6 - Updated Navigation:

• Enhanced register page with role selection and conditional farmer fields (land size, location)
• Updated navbar to show role badges and link to correct dashboard
• Role-aware authentication across both desktop and mobile views

The system is production-ready with proper session management, role-based access control, and comprehensive farmer and admin interfaces.
