SSR with @solidjs/start

[mrlubos]

Which project does this relate to?

Router

Describe the bug

Hey! I am super excited about Solid Router as seen by my timely comment. I assume this is not currently supported so perhaps a feature request, but how to use the router in SolidStart? Is it the SSR functionality I am requesting? Am I the problem?

Your Example Website or App

https://stackblitz.com/edit/github-grada5-vrkkfmhj?file=app.config.ts,src%2Fapp.tsx

Steps to Reproduce the Bug or Issue

Here's a list of changes I've made to an existing project.

1. Modify app.config.ts

import { defineConfig } from "@solidjs/start/config";
import { TanStackRouterVite } from "@tanstack/router-plugin/vite";

export default defineConfig({
  vite: {
    plugins: [
      TanStackRouterVite({
        autoCodeSplitting: true,
        target: "solid",
      }),
    ],
  },
});

2. Create routes/__root.tsx

import { Outlet, createRootRoute } from '@tanstack/solid-router'

export const Route = createRootRoute({
  component: RootComponent,
})

function RootComponent() {
  return (
    <>
      <div>Hello "__root"!</div>
      <Outlet />
    </>
  )
}

3. Modify app.tsx

import { Router } from "@solidjs/router";
import { FileRoutes } from "@solidjs/start/router";
import { createRouter } from "@tanstack/solid-router";
import { ErrorBoundary, Suspense } from "solid-js";

import { routeTree } from '~/routeTree.gen'

const router = createRouter({ routeTree });

export default function App() {
  return (
    <Router
      root={props => (
        <ErrorBoundary>
          <Suspense>
            {props.children}
          </Suspense>
        </ErrorBoundary>
      )}
    >
      <FileRoutes />
    </Router>
  );
}

This is enough to show the following error trace when I load the root page

needs ssr:false currently in solid start

[mrlubos]

Ran into another issue which has nothing to do with TanStack per se, but sharing here in case you have any thoughts spirit-led-software/clerk-solidjs#257

[brenelz]

Yeah SSR doesn't work with tanstack solid router. I've been trying to debug that client side error with no luck

[gregkonush]

yup, not quite clear how to add tanstack router into solid start setup as index.html is hidden. https://github.com/gregkonush/solit

[birkskyum]

@mrlubos , it might take a while before SSR is working with SolidStart.

On a positive note, SSR is now working for the @tanstack/solid-router on this experimental branch of TanStack Start:

• SolidJS driver for TanStack Start #3522

[mrlubos]

@birkskyum No problem, appreciate the update! As for the other issue I linked, I'm not sure what the solution would be for libraries needing to implement the "current router" navigation/components short of having a separate release/export for each. I'm slowly reducing my dependency on that package in the meantime in hopes of having an easier migration experience whenever this is ready!
