To edit the index.html, the equivalent in NextJS is the _document.js file.
A custom Document is commonly used to augment your application's
<html>and<body>tags.
import Document, { Html, Head, Main, NextScript } from 'next/document'
class MyDocument extends Document {
static async getInitialProps(ctx) {
const initialProps = await Document.getInitialProps(ctx)
return { ...initialProps }
}
render() {
return (
<Html>
<Head />
<body>
<Main />
<NextScript />
<script>...</script>
</body>
</Html>
)
}
}
If you only want to append elements to <head> tag (for a specific page), use next/head:
import Head from 'next/head'
function IndexPage() {
return (
<>
<Head>
<script>....</script>
</Head>
</>
)
}
