2. Fill in your Supabase credentials
3. Never commit .env.local to version control

​

Required Variables

​

Supabase Configuration

​

Development/Testing Variables

​

​

Model Selection by Module

​

Environment-Specific Configuration

​

Development

VITE_SUPABASE_URL=https://dev-project.supabase.co
VITE_SUPABASE_PUBLISHABLE_KEY=dev-anon-key
SUPABASE_SERVICE_ROLE_KEY=dev-service-key  # Testing only

​

Staging

VITE_SUPABASE_URL=https://staging-project.supabase.co
VITE_SUPABASE_PUBLISHABLE_KEY=staging-anon-key
# No service role key in staging client

​

Production

VITE_SUPABASE_URL=https://prod-project.supabase.co
VITE_SUPABASE_PUBLISHABLE_KEY=prod-anon-key
# No service role key in production client

​

Security Best Practices

​

1. Never Commit Secrets

• Use .env.local for local development
• Add .env.local to .gitignore
• Use .env.example as template (no real values)

• Commit .env.local with real values
• Put secrets in .env.example
• Hardcode secrets in code
• Share secrets in chat/email

​

2. VITE_ Prefix Rules

• ✅ Safe: Public URLs, anon keys, feature flags
• ❌ Never: Service role keys, API secrets, passwords

# ✅ SAFE - Public URL
VITE_SUPABASE_URL=https://project.supabase.co

# ❌ DANGEROUS - Secret exposed to client
VITE_SUPABASE_SERVICE_ROLE_KEY=xxxxx  # WRONG!

​

3. Edge Function Secrets

• Set via supabase secrets set KEY=value
• Never in .env.local or client code
• Only accessible in edge function runtime

​

4. Service Role Key

• ⚠️ Bypasses all RLS policies
• ❌ Never use in client code
• ✅ Only in test files and edge functions
• ✅ Only in development/staging

​

Variable Validation

​

Required Variables Check

// src/integrations/supabase/client.ts
const SUPABASE_URL = import.meta.env.VITE_SUPABASE_URL;
const SUPABASE_PUBLISHABLE_KEY = import.meta.env.VITE_SUPABASE_PUBLISHABLE_KEY;

if (!SUPABASE_URL || !SUPABASE_PUBLISHABLE_KEY) {
  throw new Error('Missing required Supabase environment variables');
}

​

Development Warnings

• Required variables are missing
• Service role key is used in client code (development only)
• Invalid Supabase URL format

​

How to Obtain Keys

​

Supabase Keys

1. Go to Supabase Dashboard
2. Select your project
3. Navigate to Settings → API
4. Copy:
   • Project URL → VITE_SUPABASE_URL
   • anon public key → VITE_SUPABASE_PUBLISHABLE_KEY
   • service_role key → SUPABASE_SERVICE_ROLE_KEY (testing only)

​

Email Provider Secrets

• Entra: ENTRA_CLIENT_SECRET
• Gmail: GMAIL_SERVICE_ACCOUNT_JSON

​

Twilio Credentials

1. Go to Twilio Console
2. Navigate to Account → API Keys & Tokens
3. Copy:
   • Account SID → TWILIO_ACCOUNT_SID
   • Auth Token → TWILIO_AUTH_TOKEN
4. Navigate to Phone Numbers → Manage → Active Numbers
5. Copy phone number → TWILIO_PHONE_NUMBER
6. Set via Supabase CLI:
   supabase secrets set TWILIO_ACCOUNT_SID=ACxxxxx
   supabase secrets set TWILIO_AUTH_TOKEN=xxxxx
   supabase secrets set TWILIO_PHONE_NUMBER=+1234567890
   

​

Troubleshooting

​

Issue: “Missing required Supabase environment variables”

1. Check .env.local exists
2. Verify variables are set:
   echo $VITE_SUPABASE_URL
   echo $VITE_SUPABASE_PUBLISHABLE_KEY
   
3. Restart development server
4. Check for typos in variable names

​

Issue: “Invalid Supabase URL”

1. Verify URL format: https://{project-ref}.supabase.co
2. Check for trailing slashes (remove if present)
3. Ensure HTTPS (not HTTP)

​

Issue: “Service role key in client code”

1. Remove SUPABASE_SERVICE_ROLE_KEY from .env.local
2. Only use in test files: tests/**/*.ts
3. Never import in client code: src/**/*.tsx

​

Issue: “Edge function can’t access secrets”

1. Verify secrets are set:
   supabase secrets list
   
2. Redeploy function after setting secrets:
   supabase functions deploy {function-name}
   
3. Check secret names match exactly (case-sensitive)

​

Issue: “CORS errors in development”

1. Verify VITE_SUPABASE_URL points to correct project
2. Check Supabase project CORS settings
3. Ensure edge functions include CORS headers

​

Production Deployment

​

Vercel Environment Variables

• Public client config values are defined at build time in vite.config.ts.
• vercel.json must not contain env or build.env keys.
• CI enforces this via npm run check:no-vercel-env-config.

​

Supabase Edge Function Secrets

1. Set secrets via Supabase CLI (e.g. Twilio, Entra, Gmail):
   supabase secrets set TWILIO_ACCOUNT_SID=ACxxxxx --project-ref {project-ref}
   supabase secrets set ENTRA_CLIENT_SECRET=xxxxx --project-ref {project-ref}
   
2. Or via Supabase Dashboard → Project Settings → Edge Functions → Secrets
