Supabase Integration - Implementation Summary

Overview

This document summarizes the complete Supabase integration for the BHH application, including setup instructions, testing guidelines, and deployment notes.

What Was Implemented

1. Core Infrastructure

  • Supabase Client (web/src/lib/supabaseClient.ts): Singleton client with runtime validation
  • Site URL Config (web/src/lib/siteUrl.ts): Centralized site URL management
  • Auth Hook (web/src/lib/useSupabaseAuth.tsx): React hook for auth state management

2. Authentication Pages

  • Login (web/src/pages/Auth.jsx): Uses signInWithPassword()
  • Signup (web/src/pages/Register.jsx): Uses signUp() with email confirmation and password validation
  • Password Reset Request (web/src/pages/PasswordReset.jsx): Uses resetPasswordForEmail()
  • Password Reset Flow (web/src/pages/ResetPassword.jsx): NEW page using updateUser() to set new password

3. Database Schema

  • Migration File: supabase/migrations/0001_profiles_rls.sql
  • Profiles Table: Auto-created on user signup with role field
  • RLS Policies: Users can view/update only their own profile
  • Triggers: Auto-create profile on signup, auto-update timestamp

4. Security Features

  • ✅ No secrets committed (environment variables only)
  • ✅ Runtime validation of required env vars
  • ✅ Password validation (min 6 chars, matching confirmation)
  • ✅ RLS policies on profiles table
  • ✅ Secure password reset flow
  • ✅ No CodeQL security vulnerabilities detected

Environment Setup

Required Environment Variables

Create /web/.env with:

VITE_SUPABASE_URL=your_supabase_project_url
VITE_SUPABASE_ANON_KEY=your_supabase_anon_key
VITE_PUBLIC_SITE_URL=https://bhh.icholding.cloud

Get these values from:

  1. Go to your Supabase Dashboard
  2. Project Settings → API
  3. Copy "Project URL" and "anon public" key

Example Files

  • .env.example files are committed at root and /web level
  • Copy these to .env and fill in your values

Database Setup

Option 1: Using Supabase CLI (Recommended)

# Install Supabase CLI
npm install -g supabase

# Link your project
supabase link --project-ref your-project-ref

# Apply migrations
supabase db push

Option 2: Manual SQL Execution

  1. Go to Supabase Dashboard → SQL Editor
  2. Copy contents of supabase/migrations/0001_profiles_rls.sql
  3. Execute the SQL

Verify Migration

After running migration, verify in Supabase Dashboard:

  • Table Editor → Check profiles table exists
  • Authentication → Policies → Verify RLS policies

Supabase Dashboard Configuration

CRITICAL: Configure these settings in Supabase Dashboard:

  1. Go to Authentication → URL Configuration
  2. Set Site URL: https://bhh.icholding.cloud
  3. Add Redirect URLs:
    • https://bhh.icholding.cloud
    • https://bhh.icholding.cloud/ResetPassword
    • http://localhost:5173/ResetPassword (for local dev)

Email Templates (Optional)

You can customize email templates in: Authentication → Email Templates

Testing Guide

Manual QA Checklist

1. Sign Up Flow

  • Navigate to Register page
  • Select "Client" account type
  • Fill in all required fields
  • Enter password (test validation: too short, mismatch)
  • Complete registration
  • Check email for confirmation link
  • Click confirmation link
  • Verify you can log in

2. Login Flow

  • Navigate to Login page
  • Select account type
  • Enter email and password
  • Verify successful login
  • Check that correct dashboard loads based on role

3. Password Reset Flow

  • Click "Forgot password?" on login page
  • Enter email address
  • Check email for reset link
  • Click reset link (test on desktop AND mobile)
  • Enter new password
  • Confirm password
  • Verify success message
  • Verify redirect to login
  • Log in with new password

4. Role Persistence

  • Sign up as Client
  • Verify role is "client" in Supabase profiles table
  • Log out
  • Log back in
  • Verify routed to ServicePortal (client dashboard)

5. Profile Management

  • Check Supabase profiles table
  • Verify profile auto-created on signup
  • Verify role field matches selected type
  • Verify timestamps are set

Database Verification

Run these queries in Supabase SQL Editor:

-- Check profiles table structure
SELECT * FROM pg_catalog.pg_tables WHERE tablename = 'profiles';

-- View all profiles
SELECT * FROM profiles;

-- Check RLS policies
SELECT * FROM pg_policies WHERE tablename = 'profiles';

-- Verify triggers exist
SELECT * FROM information_schema.triggers WHERE trigger_schema = 'public';

Deployment Checklist

Pre-Deployment

  • All environment variables set in deployment platform
  • Database migration applied in Supabase
  • Supabase URL configuration set correctly
  • Email templates reviewed (optional)

Post-Deployment

  • Test signup flow on production URL
  • Test login flow on production URL
  • Test password reset (receive and use email)
  • Verify mobile password reset works
  • Check that profiles are created in database
  • Verify RLS policies are working

Troubleshooting

Build Fails with Missing Environment Variables

Error: "Missing required environment variable: VITE_SUPABASE_URL"

Solution:

  • Ensure .env file exists in /web directory
  • Check that variables are prefixed with VITE_
  • Restart dev server after adding variables

Password Reset Email Not Received

Possible causes:

  1. Email in spam folder
  2. Supabase Site URL not configured
  3. Redirect URL not whitelisted

Solution:

  • Check Supabase Dashboard → Authentication → URL Configuration
  • Verify Site URL matches your domain
  • Add reset URL to redirect URLs list

Profile Not Created on Signup

Possible causes:

  1. Migration not applied
  2. Trigger not working
  3. RLS policy blocking insert

Solution:

  • Verify migration was applied: Check profiles table exists
  • Check trigger: Run SELECT * FROM information_schema.triggers WHERE trigger_schema = 'public';
  • Check Supabase logs for errors

User Can't Log In After Password Reset

Possible causes:

  1. User not confirmed email
  2. Password too short
  3. Supabase auth error

Solution:

  • Check user status in Supabase Auth → Users
  • Verify password meets minimum requirements (6 chars)
  • Check Supabase logs for authentication errors

RLS Policy Errors

Error: "new row violates row-level security policy"

Solution:

  • Verify user is authenticated
  • Check that RLS policies are correctly set
  • Ensure user ID matches profile ID

Architecture Notes

Why Two Auth Providers?

The app uses both AuthProvider (Base44) and SupabaseAuthProvider to maintain backward compatibility. This allows:

  • Gradual migration to Supabase
  • Existing features to continue working
  • New features to use Supabase auth

Role-Based Routing

After login, users are routed based on their profile role:

  • client → ServicePortal
  • worker → EmployeeDashboard
  • employee → EmployeeSignup (application)
  • admin → AdminDashboard

Profile Management

Profiles are auto-created by a database trigger when a user signs up. The client can then update the role field to match the selected account type.

Next Steps (Optional Enhancements)

1. Route Guards

Create protected route components that:

  • Check if user is authenticated
  • Verify user has correct role for page
  • Redirect unauthorized users

2. Social Auth

Add social login providers:

  • Google
  • GitHub
  • Apple

Configuration in: Supabase Dashboard → Authentication → Providers

3. Multi-Factor Authentication

Enable MFA for enhanced security:

  • SMS-based OTP
  • Authenticator apps

Configuration in: Supabase Dashboard → Authentication → Auth Providers

4. Session Management

Implement session timeout and refresh:

  • Auto-refresh tokens
  • Logout on inactivity
  • Remember me functionality
