Phase 3 Completion Summary

✅ What Was Accomplished

Phase 3 has been successfully completed with full authentication, authorization, and comprehensive documentation.

🔐 Authentication & Authorization

Middleware Implementation

Created middleware.ts with:

  • Session management via Supabase Auth
  • Role detection from JWT claims
  • Route protection based on user roles
  • Automatic redirects to appropriate dashboards
  • Public route handling for auth pages

Role-Based Access Control

Three user roles:

  1. Student (default) - Access to /dashboard/student/*
  2. Teacher - Access to /dashboard/teacher/* (+ admins can access)
  3. Admin - Access to /dashboard/admin/* (full system access)

Automatic behavior:

  • New users get 'student' role on signup
  • Role is injected into JWT by custom_access_token_hook()
  • Middleware reads role and redirects to correct dashboard
  • Unauthorized access attempts redirect to user's proper dashboard

Protected Routes

/dashboard
├── /student   → Students only
├── /teacher   → Teachers + Admins
└── /admin     → Admins only

Public routes (no auth required):

  • / (home)
  • /auth/login
  • /auth/sign-up
  • /auth/forgot-password
  • /auth/confirm
  • /auth/error

Utilities Created

lib/supabase/get-user-role.ts:

  • getUserRole() - Server-side role extraction
  • getRoleFromClaims() - Middleware role extraction
