Setting up my NextJS project with styled components and Typescript has been my current focus.
After consulting the official NextJS documentation, I successfully configured the _document.tsx file, which appears like this:
import Document, { DocumentContext } from 'next/document';
import { ServerStyleSheet } from 'styled-components';
class MyDocument extends Document {
static async getInitialProps(ctx: DocumentContext) {
const sheet = new ServerStyleSheet();
const originalRenderPage = ctx.renderPage;
try {
ctx.renderPage = () =>
originalRenderPage({
enhanceApp: (App) => (props) => sheet.collectStyles(<App {...props} />),
});
const initialProps = await Document.getInitialProps(ctx);
return {
...initialProps,
styles: (
<>
{initialProps.styles}
{sheet.getStyleElement()}
</>
),
};
} finally {
sheet.seal();
}
}
}
export default MyDocument;
However, a warning from ESLint now appears saying, "Missing return type on function."
Instead of disabling this feature in ESLint, what is the correct approach to address this issue?
Thank you!
