This lesson

This lesson teaches Deployment: the concepts, APIs, and habits you need before advancing in Next.js.

Without Deployment, you will struggle to read or extend Next.js codebases and playground exercises.

You will apply Deployment in contexts like: Marketing sites, dashboards, e-commerce, and Vercel-style deployments that need hybrid static + dynamic pages.

Write TSX for Client Components, click Run—React 18 CDN + in-browser TSX compile; use client/server lessons explain App Router concepts; mountApp renders interactive UI; printOutput feeds the terminal.

When hooks, state, and effects from intermediate lessons are familiar.

Next.js apps build to optimized server and static assets. Vercel is the zero-config path; Node, Docker, and platforms like Railway or AWS work with next start or standalone output.

Build pipeline

next build — compile routes, static pages, server bundles
next start — production Node server (or platform adapter)

Standalone output

// next.config.js
module.exports = { output: 'standalone' };

Produces a minimal deployable folder for containers—copy .next/standalone plus static assets.

Checklist before go-live

Env vars set in hosting dashboard
Error monitoring (Sentry, etc.)
Analytics and Core Web Vitals review
Preview deployments for PRs

Self-check

What command produces the production build?
When is standalone output useful?

Challenge

Deploy checklist

Run the default code to print the checklist object.
Add one item you would verify before your first deploy.

Done when: terminal shows an updated deployment checklist.

Playground

Runs in your browser in a sandboxed frame. Backend runners appear when this track’s profile allows them.
