๐ Get Started with Next.js 15 in 5 Minutes or Less (Seriously)
Next.js 15 just dropped and whether you're bootstrapping a startup, modernizing a crusty legacy app, or building your next side project at 2am with cold brew in hand โ youโre gonna want in.
This guide will get you up and running faster than a CI build on a good day.
Let's go.
๐ ๏ธ Step 1: Create Your App
Fire up your terminal and run:
npx create-next-app@latest@15 my-next-app
cd my-next-app
Youโll get a shiny new app with:
โ๏ธ Step 2: Dev Server, Meet Browser
npm run dev
Visit http://localhost:3000 and boom โ youโre live. Well, dev live.
๐งฑ Step 3: Add a Component
Head to /app/page.tsx and tweak that JSX:
export default function Home() {
return (
<main className="p-6">
<h1 className="text-4xl font-bold">Welcome to Next.js 15 ๐</h1>
<p>You're up and running in under 5 minutes. Time for a celebratory snack.</p>
</main>
);
}
Want Tailwind CSS? Run this:
npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p
Then configure your tailwind.config.js and globals.css.
๐ก Bonus: Edge-Ready APIs
Next.js 15 loves the edge. Want a fast API?
// app/api/hello/route.ts
export async function GET() {
return Response.json({ msg: 'Hey from the edge ๐ง' });
}
Done.

You can still keep it simple or go full enterprise mode โ your call.
