DevOps, Domains & Infrastructure Standards

Complete standards for deployment infrastructure, CI/CD pipelines, domain management, monitoring, and the subdomain branding strategy. The operational backbone for every shipped project.

Overview

This standard covers the operational infrastructure behind every project — how code moves from commit to production, how domains and subdomains are managed, how services are monitored, and the overarching brand/subdomain strategy.

Prerequisites: General Standards (Git workflow, security).

What this covers:

• CI/CD pipeline configuration
• Deployment platforms (Vercel, Cloudflare, GitHub Actions)
• Domain & subdomain strategy (centralized branding)
• DNS configuration
• Error monitoring (Sentry)
• Performance monitoring (Lighthouse CI)
• Environment and secrets management

CI/CD Pipeline

Universal Pipeline

Every project follows this CI/CD pattern:

Local → Commit → GitHub → CI (check, test, build) → Deploy (production)

GitHub Actions Workflow Template

name: CI/CD
on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  quality:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '22'
          cache: 'npm'
      - run: npm ci
      - run: npm run check
      - run: npm test
      - run: npm run build
        env:
          PUBLIC_SENTRY_DSN: ${{ secrets.SENTRY_DSN }}
          SENTRY_AUTH_TOKEN: ${{ secrets.SENTRY_AUTH_TOKEN }}

Pipeline Steps Explained

Pre-Commit Hooks (Husky)

// .husky/pre-commit
npm run check
npm test
npm run build

All three must pass before a commit is created. This catches issues at the earliest possible point.

Deployment Platforms

Primary: Vercel

When to Use Alternatives

Domain & Subdomain Strategy

The Principle

One domain. Unlimited subdomains. Zero extra cost.

Instead of buying dozens of custom domains (labelkit.com, xcelerate.app, sounds.io), centralize everything under a single personal brand domain. This:

• Saves $10–20/year × dozens of projects
• Builds a single strong brand identity
• Makes management trivial (one DNS zone)
• Creates memorable, professional URLs

Brand Domain Options (Non-Exhaustive)

Recommendation: Purchase the full name .com for professionalism. Add a short .dev variant for subdomain-only use if desired.

Subdomain Naming Convention

{project}.byjtt.com

Examples:

DNS Configuration

Per-project setup on Vercel:

1. Deploy project to Vercel (gets {project}.vercel.app)
2. Go to project → Settings → Domains
3. Add {project}.byjtt.com
4. Vercel provides a CNAME record — add it to your DNS provider
5. Wait for DNS propagation (5–30 minutes typically)

DNS Provider: Cloudflare (recommended) or your registrar's default DNS.

On Vercel Hobby (free) plan: Up to 50 domains per project — more than enough.

Decision Tree: Subdomain vs Path vs Separate Domain

Does this project need its own domain for branding or trust?
├── YES, and budget allows separate domain
│   → Buy a specific domain (e.g., xcelerate.app)
├── YES, branding matters but budget is tight
│   → Use subdomain (xcelerate.byjtt.com)
└── NO, it's part of the main site
    → Use path (byjtt.com/projects/xcelerate)

Monitoring & Observability

Error Tracking: Sentry

Every production project gets Sentry:

// Initialization (lazy-loaded, non-blocking)
const dsn = import.meta.env.PUBLIC_SENTRY_DSN;
if (dsn) {
  const Sentry = await import('@sentry/browser');
  Sentry.init({
    dsn,
    integrations: [Sentry.browserTracingIntegration()],
    tracesSampleRate: 0.1,  // 10% sampling to stay within free tier
  });
}

Configuration:

• Lazy load Sentry — never block page render for monitoring
• Sample rate: 0.1 (10%) for browser tracing
• Error grouping by environment and release version
• Source maps uploaded for readable stack traces (Vercel integration)

Performance Monitoring: Lighthouse CI

# lighthouserc.json
{
  "ci": {
    "collect": {
      "numberOfRuns": 3,
      "staticDistDir": "./dist"
    },
    "assert": {
      "assertions": {
        "categories:performance": ["error", { "minScore": 0.95 }],
        "categories:accessibility": ["error", { "minScore": 0.95 }],
        "categories:best-practices": ["error", { "minScore": 0.95 }],
        "categories:seo": ["error", { "minScore": 0.95 }]
      }
    }
  }
}

Run in CI on every PR to catch regressions before they reach production.

Health Checks

• Uptime monitoring: Vercel built-in (Hobby plan includes basic monitoring)
• Synthetic checks: GitHub Actions cron job hitting /api/health endpoints
• Real user monitoring: Sentry performance traces (sampled)

Environment & Secrets Management

Environment Variables

Secret Management Rules

1. Never commit secrets — .env files are in .gitignore
2. Use .env.example — committed to repo with placeholder values
3. Vercel Environment Variables — set in project dashboard
4. GitHub Secrets — for CI/CD tokens (SENTRY_AUTH_TOKEN, VERCEL_TOKEN)
5. Rotate regularly — if a secret is compromised, rotate immediately
6. Principle of least privilege — each token has the minimum scope needed

Environment Setup Checklist

• [ ] .env.example created with all variables (no values)
• [ ] Production variables set in Vercel/Cloudflare dashboard
• [ ] CI/CD secrets added to GitHub repository secrets
• [ ] Local development environment documented in README
• [ ] No secrets in source code, compiled output, or build logs

Lighthouse CI Configuration

Local Assertion Targets

The only acceptable score for production is 100 across all categories. The 95 minimum is a CI gate — if it drops below 95, the build fails. Aim for 100 and diagnose any regression immediately.

Review & Shipping Checklist

• [ ] CI/CD pipeline configured and passing
• [ ] Preview deployment verified (all features work)
• [ ] Custom domain/subdomain added in Vercel
• [ ] DNS records configured and propagated
• [ ] Sentry configured with DSN and source maps
• [ ] Lighthouse CI assertion file committed
• [ ] Environment variables set in production
• [ ] .env.example committed to repo
• [ ] GitHub repository secrets configured
• [ ] Production build tested locally
• [ ] SSL/HTTPS verified (auto via Vercel/Cloudflare)

Trends to Watch (2026+)

• Edge infrastructure — More workloads shifting to edge compute for lower latency
• GitOps — Infrastructure defined in Git, deployed via PRs
• AI-assisted operations — LLMs analyzing logs, suggesting fixes, automating incident response
• Observability convergence — Merging logs, traces, and metrics into unified platforms (OpenTelemetry)
• Zero-downtime deployments — Becoming standard expectation even for small projects
• Serverless maturation — Reduced cold starts, lower costs, broader language support
