[Swiper Element] Server Side Component Support

[tomm1996]

Clear and concise description of the problem

In a npx create-next-app@latest boilerplate add this component

'use server'

import { register } from 'swiper/element';

register();

export const Slider = () => {
    return (
        <div style={{"width": "80vw"}}>
            <swiper-container>
                <swiper-slide>
                    <h2>Slide 1</h2>
                </swiper-slide>
                <swiper-slide>
                    <h2>Slide 2</h2>
                </swiper-slide>
                <swiper-slide>
                    <h2>Slide 3</h2>
                </swiper-slide>
            </swiper-container>
        </div>
    );
}

You will receive this error:

Unhandled Runtime Error
Error: Hydration failed because the initial UI does not match what was rendered on the server.

Warning: Expected server HTML to contain a matching <swiper-slide> in <swiper-container>.

Suggested solution

• split importable modules into template & component
• Remove references to window from potential server-side code

Any updates on this? We are updating to react 18, and this is causing us to have to force any elements that have a react swiper to be rendered client side. If we can, we would love to be able to render them on the server. There is no data in them that requires loading on the client.

same here, let's go HEROS!

For anyone trying to use swiper in react, suggest to migrate to embla that's used under the hood in shadcn https://github.com/davidjerleke/embla-carousel
