This example features how you use a different styling solution than styled-jsx that also supports universal styles. That means we can serve the required styles for the first render within the HTML and then load the rest in the client. In this case we are using styled-components.
This example uses the Rust-based SWC in Next.js for better performance than Babel.
Currently, only the ssr
and displayName
transforms have been implemented. These two transforms are the main requirement for using styled-components
in Next.js.
Deploy the example using Vercel or preview live with StackBlitz
Execute create-next-app
with npm, Yarn, or pnpm to bootstrap the example:
npx create-next-app --example with-styled-components with-styled-components-app
yarn create next-app --example with-styled-components with-styled-components-app
pnpm create next-app --example with-styled-components with-styled-components-app
Deploy it to the cloud with Vercel (Documentation).

When wrapping a Link from next/link
within a styled-component, the as prop provided by styled
will collide with the Link's as
prop and cause styled-components to throw an Invalid tag
error. To avoid this, you can either use the recommended forwardedAs prop from styled-components or use a different named prop to pass to a styled
Link.

import Link from 'next/link'
import styled from 'styled-components'
const StyledLink = ({ as, children, className, href }) => (
<Link href={href} as={as} passHref>
<a className={className}>{children}</a>
</Link>
)
export default styled(StyledLink)`
