What is the page title rendered by this Next.js static metadata?

Given this Next.js page component with static metadata, what will be the page title shown in the browser tab?

NextJS

export const metadata = {
  title: 'Welcome to My Site',
  description: 'A simple Next.js app'
};

export default function Page() {
  return <main><h1>Hello World</h1></main>;
}

A A simple Next.js app

B Welcome to My Site

C Hello World

D Page

💡 Hint

Look at the metadata object and see which property sets the page title.

The 'title' property inside the static metadata object sets the page title shown in the browser tab.

📝 Syntax

intermediate

Which option correctly defines static metadata in a Next.js page?

Choose the correct syntax to define static metadata for a Next.js page component.

A export const metadata = { title: 'Home' };

B export function metadata() { return { title: 'Home' }; }

C const metadata = { title: 'Home' }; export default metadata;

D export default function metadata() { return { title: 'Home' }; }

💡 Hint

Static metadata must be exported as a constant object, not a function or default export.

Next.js expects static metadata as a named export constant object called 'metadata'.

What is the description meta tag content rendered by this static metadata?

Given this static metadata in a Next.js page, what will be the content of the description meta tag in the HTML?

NextJS

export const metadata = {
  title: 'About Us',
  description: 'Learn more about our company and team.'
};

export default function About() {
  return <main><h1>About</h1></main>;
}

A About Us

B No description meta tag is rendered

C About

D Learn more about our company and team.

💡 Hint

The 'description' property in metadata sets the meta description tag content.

The 'description' property in the static metadata object sets the content of the meta description tag in the HTML head.

Why does this static metadata not update the page title?

This Next.js page has static metadata but the browser tab title remains 'Document'. What is the likely cause?

NextJS

const metadata = {
  title: 'Dashboard'
};

export default function Dashboard() {
  return <main><h1>Dashboard</h1></main>;
}

A The page component must be named 'Page' for metadata to work.

B The title property must be inside a function, not an object.

C The metadata object is not exported, so Next.js ignores it.

D Static metadata only works in server components, not client components.

💡 Hint

Check if the metadata object is properly exported for Next.js to detect it.

Next.js requires the metadata object to be exported with 'export const metadata' to apply it.

🧠 Conceptual

Which statement about Next.js static metadata is TRUE?

Select the true statement about how static metadata works in Next.js 14+.

A Static metadata is defined as a named export and is used to generate HTML head tags at build time.

B Static metadata can be dynamically changed at runtime based on user input.

C Static metadata requires a special hook to update the page title after rendering.

D Static metadata must be defined inside the page component function to take effect.

💡 Hint

Think about when static metadata is processed and how it affects the HTML.

Static metadata is a named export object used by Next.js at build time to generate head tags, not changed dynamically.
