SSR and routes in Solid.JS

On the Solid.JS website, it is stated that it supports server-side rendering (SSR). However, I am unable to find a straightforward method for SSR with routing. For instance, if I consider the following example:

import express from "express";
import { renderToString } from "solid-js/web";

function App() {
  return <h1>Hello World</h1>;
}

const app = express();

app.get("/", (req, res) => {
  const html = renderToString(() => <App />);
  res.send(html);
});

app.listen(3000, () => {
  console.log("Server started on port 3000");
});

import express from "express";
import { renderToString } from "solid-js/web";

function App() {
  return <h1>Hello World</h1>;
}

const app = express();

app.get("/", (req, res) => {
  const html = renderToString(() => <App />);
  res.send(html);
});

app.listen(3000, () => {
  console.log("Server started on port 3000");
});

(https://docs.solidjs.com/references/concepts/ssr/simple-client-fetching-ssr) Although this code works, it does not explain how to incorporate routing. Is there a way to make it work based on the request URL received by Express without requiring modifications to the App component?

https://start.solidjs.com/getting-started/what-is-solidstart is probably a better place to start

So there isn't any way to do that in Solid.JS ?

I imagine it is possible, I would be surprised if it wasn't, but why would you want to do all the route plumbing to/from express routing yourself? is using express's route engine a necessity? otherwise https://start.solidjs.com/core-concepts/routing (all the routing magic for both server and client side all ready for you) and https://start.solidjs.com/core-concepts/api-routes for routes that are only server side

True but express/js is ancient on the flip side of the coin is TJ even still maintaining it

https://github.com/ryansolid/solid-ssr-workbench is linked in that page. most of what you need should be there.

Well, it works in JavaScript. But in TypeScript it's another story. If you do

npx degit solidjs/templates/ts my-app
cd my-app
npm install # or yarn or pnpm
npm run dev # or yarn or pnpm

npx degit solidjs/templates/ts my-app
cd my-app
npm install # or yarn or pnpm
npm run dev # or yarn or pnpm

And after that, try to create a server.tsx with something like:

import express from "express";
import { renderToString } from "solid-js/web";

function App() {
  return <h1>Hello World</h1>;
}

const app = express();

app.get("/", (req: any, res: any) => {
  const html = renderToString(() => <App />);
  res.send(html);
});
app.listen(3000, () => {
  console.log("Server started on port 3000");
});

import express from "express";
import { renderToString } from "solid-js/web";

function App() {
  return <h1>Hello World</h1>;
}

const app = express();

app.get("/", (req: any, res: any) => {
  const html = renderToString(() => <App />);
  res.send(html);
});
app.listen(3000, () => {
  console.log("Server started on port 3000");
});

And try to run the server with ts-node src/server.tsx you fall in a rabbit hole of errors. Like Unknown file extension ".tsx", and after that, you try to remove "type": "module", in package.json, but new errors are coming. It would be great to have a default template for SSR in typescript that actually work out of the box.

solid uses a custom jsx transform so the babel transform is necessary along the build pipeline it should work if babel typescript preset is thrown in there
