Next.js: populate the head tag with custom tags

From any Next.js page component, you can add information to the page header.

This is handy when:

you want to customize the page title
you want to change a meta tag

How can you do so?

Inside every component you can import the Head component from next/head and include it in your component JSX output:

import Head from 'next/head'

const House = props => (
  <div>
    <Head>
      <title>The page title</title>
    </Head>
    {/* the rest of the JSX */}
  </div>
)

export default House

You can add any HTML tag you’d like to appear in the <head> section of the page.

When mounting the component, Next.js will make sure the tags inside Head are added to the heading of the page. Same when unmounting the component, Next.js will take care of removing those tags.
