Setting Environment Variables in Netlify

​

Security Best Practices

1. Add .env to .gitignore:
   .gitignore

   .env
   .env.local
   .env.*.local
   
2. Use .env.example for documentation: Create a template file without sensitive values:
   .env.example

   RESEND_API_KEY=your_resend_api_key_here
   
3. Rotate keys regularly: Change API keys periodically and after any suspected compromise
4. Use different keys for development and production: Never use production API keys in development
5. Limit key permissions: Use API keys with minimum required permissions

​

Validation

try {
  await resend.emails.send({...});
} catch (emailError) {
  console.error('Error sending email:', emailError);
}
