This is the way I set up the component

import { Name } from "./_components/name";
import { createEleventContextProvider } from "./_utilities/eleventy-context";

export const data = {
  layout: "html",
  title: "Preact Test",
};

export const render = createEleventContextProvider(
  ({ data: title }: { data: typeof data }) => (
    <>
      <h1>{title}</h1>
      <Name />
    </>
  )
);

The Name component is using the useEleventyContext hook as a test but it's not actually important here.

Nicer than what I came up with, thanks @pspeter3

@pspeter3 Can I see your component? Curious if you've eliminated import of h and what are your return types.

I did manage to eliminate h but I think there is an issue with esbuild-register not respecting the jsx-import-source flag.

@pauleveritt

@pspeter3 I think I have h replaced, but have some typing things happening. Any chance you're up for a demo repo or a Google Meet?

@pauleveritt

@pspeter3 Here's a recreation of what I'm struggling with. I can make a full repo if it would help https://gist.github.com/pauleveritt/bef52a4f1f7dd9d7d77ed5d53d8d08a3

My guess is that .bind isn't doing what I think it's doing. But inside MyView, the this isn't what it's supposed to be. I tried adding it to the MyView args list but couldn't get the typing right.

@pauleveritt

@pspeter3 I made a repo with the minimal example but the render function is returning an object (from JSX processing) when 11ty expects a string. Obviously I don't have the h/rendering installed correctly in tsconfig.

As a note to others: esbuild-register appears to have landed jsxImportSource last year. Need to investigate how to make it work.

@pspeter3

That's for esbuild unfortunately. You need egoist/esbuild-register#84

Both the above esbuild-register and new tsx approaches are now on the official docs, thanks everyone!
