I just started using TypeScript with Next. What does this do? import { NextPage } from 'next'; export const Page: NextPage = () => {} I looked at the docs but it does really give a good explanation in what it does.

I am guessing by the name that it routes pages. Can someone please explain what this does?

Thank you.

My advice is to start here, but in brief:

import { NextPage } from 'next';

export const Page: NextPage = () => {}

NextPage is a type exported by NextJS. When we write Page: NextPage we're saying that our Page ponent is of type NextPage.

import { NextPage } from 'next'; : This line imports the NextPage type from the next package. The NextPage type is a generic type provided by Next.js for defining the type of a Next.js page ponent.

When you create a page in Next.js, you typically define it as a React ponent. The NextPage type is a type alias for a React ponent that is a Next.js page. It includes properties specific to Next.js pages, such as getStaticProps, getServerSideProps, and others used for data fetching during page rendering.

So, in summary, the code you provided is creating a Next.js page ponent using TypeScript. It is defining a constant named Page with the type NextPage and providing the logic for your page within the arrow function. This is a mon pattern when working with Next.js and TypeScript to ensure type safety and provide better development tooling support.
