Security Checklist
1. Secrets Management
FAIL: NEVER Do This
const apiKey = "sk-proj-xxxxx" // Hardcoded secret
const dbPassword = "password123" // In source code
PASS: ALWAYS Do This
const apiKey = process.env.OPENAI_API_KEY
const dbUrl = process.env.DATABASE_URL
// Verify secrets exist
if (!apiKey) {
throw new Error('OPENAI_API_KEY not configured')
}
Verification Steps
- No hardcoded API keys, tokens, or passwords
- All secrets in environment variables
-
.env.localin .gitignore - No secrets in git history
- Production secrets in hosting platform (Vercel, Railway)
