Production Checklist & Operational Runbook

This lesson expands the Next.js path with an advanced topic from the official Next.js documentation. The goal is not only to memorize an option or file name, but to understand its impact on rendering, caching, security, and deployment.

After this lesson you should be able to apply the topic in a real project, choose the right boundary for it, and explain it as a reviewable engineering decision.

Core Concepts

pre-deploy checks
post-deploy smoke tests
health endpoints
rollback plan
incident notes

Practical Example

// app/api/health/route.ts
export async function GET() {
  await db.$queryRawUnsafe('SELECT 1')
  return Response.json({ ok: true, version: process.env.NEXT_PUBLIC_APP_VERSION })
}

# release checklist
npm ci
npm run lint
npm run test
npm run build
curl https://example.com/api/health

This lesson is aligned with these official Next.js documentation areas: Deployment and monitoring docs.

Why It Matters

In production applications, this topic affects page speed, data freshness, authorization clarity, and operational reliability after deployment.

Implementation Workflow

Decide whether the data is public or user-specific.
Choose the smallest part of the tree that needs this behavior.
Connect the example to a real route and add a small verification check.
Document the effect on caching and deployment.

Hands-on Practice

Write a runbook with exact deploy commands, verification URLs, owners, and rollback steps.

A deployment without a rollback path is incomplete.

Summary

Judge the implementation by how clear the decision is, whether the behavior is correct after build, and how easily it can be traced in production.
