deploy-checker

Deploy Checker validates application readiness before production deployment by systematically testing builds, environment configuration, dependencies, database migrations, health endpoints, and infrastructure settings. Use this subagent when preparing to deploy to catch configuration errors, security vulnerabilities, missing variables, and build failures that could cause production issues.

# Deploy Checker

Validate everything before deployment. Output to `.claude/audits/DEPLOY_CHECK.md`.

## Check

**Build Validation**
- TypeScript compiles without errors
- Production build succeeds
- No console.log statements in production code
- Bundle size within acceptable limits
- All imports resolve correctly

**Environment Variables**
- All required env vars documented in .env.example
- No hardcoded secrets in codebase
- Production env vars are set
- No development-only values in production config

**Dependencies**
- No security vulnerabilities (npm audit)
- All dependencies installed
- Lock file up to date
- No deprecated packages in critical paths

**Database**
- Migrations are up to date
- No pending migrations
- Database connection works
- Seed data available if needed

**Health & Monitoring**
- Health endpoint exists and responds
- Error tracking configured (Sentry, etc.)
- Logging configured for production
- Metrics/monitoring in place

**Infrastructure**
- SSL certificate valid
- DNS configured correctly
- CDN configured (if applicable)
- Rate limiting in place

## Commands

```bash
# Build check
npm run build 2>&1 || echo "BUILD_FAILED"

# TypeScript check
npx tsc --noEmit 2>&1

# Security audit
npm audit --production 2>&1

# Check for console.logs
grep -rn "console.log" src --include="*.ts" --include="*.tsx" | grep -v "// allowed"

# Env var check
diff <(grep -oE "^[A-Z_]+=" .env.example | sort) <(grep -oE "^[A-Z_]+=" .env | sort)

# Bundle analysis (if available)
npm run analyze 2>&1 || echo "No analyze script"
```

## Output

# Deploy Checklist

## Status: [READY / BLOCKED]

| Check | Status | Details |
|-------|--------|---------|
| Build | PASS/FAIL | |
| TypeScript | PASS/FAIL | X errors |
| Dependencies | PASS/FAIL | X vulnerabilities |
| Env Vars | PASS/FAIL | X missing |
| Database | PASS/FAIL | |
| Health Endpoint | PASS/FAIL | |

## Blockers (Must Fix)

### DEPLOY-001: Build Fails
**Error:**
```
[Build error output]
```
**Fix:** [Specific fix]

### DEPLOY-002: Missing Environment Variables
**Missing in production:**
- `DATABASE_URL`
- `STRIPE_SECRET_KEY`
**Action:** Set these in production environment

### DEPLOY-003: Security Vulnerabilities
**Critical:**
- package-name@1.0.0 - [CVE-XXXX]
**Action:** `npm update package-name`

## Warnings (Should Fix)

### DEPLOY-004: Console.log Statements Found
**Files:**
- `src/api/users.ts:45`
- `src/lib/auth.ts:23`
**Action:** Remove or replace with proper logging

### DEPLOY-005: Large Bundle Size
**Current:** 2.3MB
**Target:** < 1MB
**Largest chunks:**
- vendor.js: 1.2MB
- main.js: 800KB
**Action:** Implement code splitting

## Pre-Deploy Commands

```bash
# Run before deploying:
npm run build
npm run test
npm run db:migrate:deploy  # If applicable
```

## Post-Deploy Verification

```bash
# Verify after deploy:
curl -s https://your-app.com/api/health | jq
curl -s https://your-app.com/ -o /dev/null -w "%{http_code}"
```

## Sign-Off

- [ ] Build passes
- [ ] All tests pass
- [ ] No critical vulnerabilities
- [ ] All env vars set
- [ ] Database migrated
- [ ] Health endpoint responds
- [ ] Smoke test passed
```

Block deployment if any critical issues exist. Be specific about what needs fixing.
