Hey, I suggest adding the following to the script section in the package.json example just to demonstrate how to use the eleventy flags
"serve":"node --require esbuild-register node_modules/.bin/eleventy --serve"
As an update: @khalidabuhakmeh and I have gotten very, very far into this. One place we stumbled: vhtml doesn't support async. When we got to a component that needed to render an image, we were in trouble.
We investigated Nano JSX, dropped it in. Was quite interesting. The vhtml got its last activity 3 years ago, whereas Nano JSX is quite active. Unfortunately the Suspense component didn't really pan out for the renderSSR approach.
We found a clever workaround on the issue involving, of all things, collections.
Why not put the config file in ts too?
"dev": "node --require esbuild-register node_modules/.bin/eleventy --config=.eleventy.ts --serve"
Well @khalidabuhakmeh put our Gatsby->11ty 2.0 plus TS/TSX/Vite rewrite into production last week. It's been a blast. We did some neat content and component things.
Thanks all for this gist which I stumbled across in December and completely changed directions.
I'm curious how you're using Vite and 11ty together
@pspeter3 We plan soon to write a bunch of stuff about what we're doing. I'll confess, I approached this as writing a larger system, Gatsby-ish.
I have a wild idea for a next step. To avoid prop drilling, I'd like child components to have access to the this: Context above. It's hard: vhtml is the caller. I have an idea for that. But I worry the work @zachleat is doing on dependency tracking for incremental will get broken.
@pspeter3 You up for doing a Meet sometime, I can show you what we did? You after all were the trigger. 😀
Sure! Definitely curious to learn more. I also think you may be able to use Preact instead of vhtml so you can pass the data via context. I also think that may be better for memory since vhtml does some caching internally. I'll try playing with that idea today and let you know how it goes.
@pspeter3 Here is a fairly-recent setup: https://github.com/pauleveritt/g3-tsx ... just before we got out of spike solution mode. Interesting bits:
- Use Typebox to read frontmatter into validated schemas
- Custom collections which provide instances of our validated, cleaned-up resource classes
- A (still primitive) reference system which dereferences relations after the content model is built
- A very aggressive testing strategy
@pspeter3 Did you ever get a chance to play with preact to pass data via context?
I'd like to clean up the types better but I got a working prototype with the following:
import { createContext } from "preact";
import { useContext } from "preact/hooks";
import type { FunctionComponent, VNode } from "preact";
export interface EleventyContext {}
const Context = createContext<EleventyContext | null>(null);
export type EleventyComponent<T> = (
this: EleventyContext,
data: T
) => VNode<{}>;
export function createEleventContextProvider<T>(
Component: FunctionComponent<{ data: T }>
): EleventyComponent<T> {
return function (this: EleventyContext, data: T): VNode<{}> {
return (
<Context.Provider value={this}>
<Component data={data} />
</Context.Provider>
);
};
}
export function useEleventyContext(): EleventyContext {
const value = useContext(Context);
if (value === null) {
throw new Error("Missing EleventyContext");
}
return value;
}
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.
@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?
@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.
@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.
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!

I’m assuming those questions are directed at me and the answer to both is yes.
