Setup

What's a Next.js developer's favorite part of setting up a new project?
Installing dependencies. It's like Christmas, but every package is a surprise!

Creating a Next.js Project

Run the following command to create a new Next.js project:

pnpm create next-app

Give your project a name and select the following options:

  • we want to use TypeScript
  • we want to use ESLint
  • we want to use Tailwind CSS
  • we want to use the src/ directory
  • we want to use the App Router
  • we don't want to customize the defalt import alias

Next, navigate to the newly created directory and run:

pnpm dev

Note that pnpm create next-app automatically runs pnpm install, so you don't need to worry about that.

If you go to http://localhost:3000, you will see the default home page. Let's simplify it a bit for the following sections.

Simplifying the Default Project

Enter the src directory.

First, remove the globals.css file (styles will be the topic of the next chapter).

Next, replace the code in page.tsx with this:

export default function Home() {
  return <h1>Welcome</h1>;
}

Finally, replace the code in layout.tsx with this:

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <html lang="en">
      <body>{children}</body>
    </html>
  );
}

Go to http://localhost:3000 again and observe the simplified home page.
