Customizing _app.js and _document.js pages

There are certain cases where you need to take control over page initialization, so that every time we render a page, Next.js will need to run certain operations before sending the resulting HTML to the client. To do that, the framework allows us to create two new files, called _app.js and _document.js, inside our pages/ directory.

The _app.js page

By default, Next.js ships with the following pages/_app.js file:

import '../styles/globals.css'
function MyApp({ Component, pageProps }) {

import Link from 'next/link...
