View transition api and solid start

Has anybody gotten view transition api working reliably with solid router? I tried following code but it doesnt work always for some reason.

const VtApi: ParentComponent = (props) => {
    const transition = (fnStartingTheSynchronousTransition) => {
        // In case the API is not yet supported
        if (!document.startViewTransition) {
            return fnStartingTheSynchronousTransition();
        }

        // Transition the changes in the DOM
        const transition = document.startViewTransition(
            fnStartingTheSynchronousTransition,
        );
    };

    useBeforeLeave((e) => {
        // Stop the inmediate navigation and DOM change
        if (!e.defaultPrevented) {
            e.preventDefault();

            // Perform the action that triggers a DOM change synchronously
            transition(() => {
                e.retry(true);
            });
        }
    });

    return <>{props.children}</>;
};

export default VtApi;

const VtApi: ParentComponent = (props) => {
    const transition = (fnStartingTheSynchronousTransition) => {
        // In case the API is not yet supported
        if (!document.startViewTransition) {
            return fnStartingTheSynchronousTransition();
        }

        // Transition the changes in the DOM
        const transition = document.startViewTransition(
            fnStartingTheSynchronousTransition,
        );
    };

    useBeforeLeave((e) => {
        // Stop the inmediate navigation and DOM change
        if (!e.defaultPrevented) {
            e.preventDefault();

            // Perform the action that triggers a DOM change synchronously
            transition(() => {
                e.retry(true);
            });
        }
    });

    return <>{props.children}</>;
};

export default VtApi;

Do you know when exactly it doesn't work? My implementation looks similar and it works fine

It works like 70% of the time on routing. I have no idea on what situations it fails.

import type { ParentComponent } from "solid-js"; 
 import { type RouteSectionProps, useBeforeLeave } from "@solidjs/router"; 
  
 import "./view-transition.css"; 
 export const ViewTransition: ParentComponent<RouteSectionProps> = (props) => { 
   let isTransitionNavigate = false; 
  
   useBeforeLeave((event) => { 
     if (document.startViewTransition) { 
  
       // if this is not already the second navigation, 
       // which happens after the view-transition was initialized from inside this component 
       if (!isTransitionNavigate) { 
         const isBackNavigation = Number.isInteger(event.to) && (event.to as number) < 0; 
  
         event.preventDefault(); 
  
         isTransitionNavigate = true; 
  
         if (isBackNavigation) { 
           document.documentElement.classList.add("back-navigation");

           document.documentElement.classList.remove("back-navigation"); 
         }); 
       } 
     }

   return <>{props.children}</>; 
 };

This is my solution and it works... I am not at my computer rn so can't really dig deeper

Thanks a lot. With your code it works pretty much always.

Luka•2mo ago

Oohh I would like to use this too! Where do I place this code? In app.tsx as a comp?

Massukka•2mo ago

I wrapped props.children with this component in app.tsx. Desktop works for the most part but i am still having issues with mobile browsers
