Build Your First Fullstack App with Next.js 16

From `pnpm create` to PostgreSQL via Drizzle ORM, deployed to Fly.io. 4 hands-on steps.

Start with Step 1 →

Difficulty: Intermediate
Lessons: 4

"What is Next? What is App Router? What's a Server Component anyway?" — this course answers each question with real code.

Who is this for

React basics done, but App Router is new for you
Want a fullstack app without standing up a separate backend
Want to finish one cycle including DB

What you'll have built

Felt the difference between Server / Client Components
Built an API Route that takes external calls
Stored & queried data via Drizzle ORM + PostgreSQL
Deployed to Fly.io (or Vercel)

Flow

Publishing one complete feature

Setup

Establish a project foundation with fixed type, styling, and runtime contracts.

Render boundary

Split data and interaction responsibilities between server and client components.

Persistence

Connect API input and failure contracts to the database write path.

Deployment

Verify the public state through build, environment configuration, and health checks.

A single project walks through 4 steps: "empty folder → screen → data → live on the internet."

Steps

Setup — pnpm create next-app + Tailwind v4 + TypeScript strict
Server vs Client Components — what 'use client' actually means
API Route + Drizzle ORM — /api/posts POST/GET, postgres connection
Deploy — Docker standalone build, Fly.io free tier deploy

Each step layers code on top of the previous, so by step 4 the same project reaches deployment.
