How to install peer dependencies in ipyreact?

[kolibril13]

For jupyter-tldraw, I am currently using the old version 1 of tldraw, but now there is a new version 2.

The docs say I should install like this:
npm install @tldraw/tldraw@alpha signia signia-react
because tldraw v2 has peer dependencies on signia and signia-react.

I tried
import { Tldraw } from "@tldraw/tldraw@alpha";
but that did not work.

I got this error message in the console:

Multiple versions of signia detected. This will cause unexpected behavior.   
Please add "resolutions" (yarn/pnpm) or "overrides" (npm) in your package.json to ensure only one version of signia is loaded.
(anonymous) @ index.ts:11

Does someone have an idea how I can get the signia and signia-react dependencies installed?

Here is the full example

%%react

import * as React from "react";
import {  } from "@tldraw/signia";

import { Tldraw } from "@tldraw/tldraw@alpha";



export default function App() {
  return (
    <div
      style={{
        position: "relative",
        width: "800px",
        height: "350px",
      }}
    >
      <Tldraw />
    </div>
  );
}

The idea of ipyreact and (anywidget) is that you don't need to use npm/webpack (although you could generate a esm bundle probably).

However, it's weird it does not work... I'm not sure the peer dependency matters for esm.

Thanks for these insights!

Three questions that might help in resolving this issue:
At what location is ipyreact storing the packages?
Are there maybe cached versions of that package somewhere on my system? If yes, how can I delete them ?
Is there an equivalent of npm install in ipyreact?

[maartenbreddels]

It's getting them from esm.sh (watch your browser network tab to see them being downloaded on the fly)
This is not ipyreact, it's ES modules (esm) feature of browsers.

[kolibril13]

In the browser network tab I can indeed see an error when I try to import the new version:
import { Tldraw } from "@tldraw/tldraw@alpha".

[maartenbreddels]

yeah, saw that as well, but that is probably not related, although seems like some kind of packaging issue in tldraw.

Maybe it is not a solution, but you can check this out on https://esm.sh/#docs which can be used with _import_map as well:

Specify Dependencies
By default, esm.sh rewrites import specifiers based on the package dependencies. To specify the version of these dependencies, you can add the ?deps=PACKAGE@VERSION query. To specify multiple dependencies, separate them with a comma, like this: ?deps=react@17.0.2,react-dom@17.0.2.

import React from "https://esm.sh/react@17.0.2"
import useSWR from "https://esm.sh/swr?deps=react@17.0.2"

[maartenbreddels]

Note that React is already 'baked' in, because we need to run react. It's currently shipping with 18 only.

@gergomiklos : Thanks a lot for pointing me to the docs!

I also just discovered that they have a code playground at https://code.esm.sh/, that's great to reproduce errors!
One question in that regard: When I get an example to work in that online playground, will it also likely work in ipyreact then?

Regarding tldraw, this example works fine:

import * as React from "https://esm.sh/react";
import { Tldraw } from "https://esm.sh/@tldraw/tldraw";

export default function App() {
  return (
    <div
      style={{
        position: "relative",
        width: "600px",
        height: "350px",
      }}
    >
      <Tldraw />
    </div>
  );
}

when I now try to change to the alpha version by changing the line

- import { Tldraw } from "https://esm.sh/@tldraw/tldraw";
+ import { Tldraw } from "https://esm.sh/@tldraw/tldraw?deps=@tldraw/tldraw@alpha";

I still get the old version rendered, and not the latest alpha application.
In case that you have other ideas on what else I can try, let me know :)

I've talked to the tldraw creator, and he told me that import { Tldraw } from "@tldraw/tldraw@alpha";
should work fine, I only would only have to provide the fonts and icons assets as folders.

This leads me to the next question:
How can I access files from the Jupyter localhost address?
For testing, I've created a file my_file.txt in the project directory and started jupyterlab, but when I tried to access it via
http://localhost:8889/my_file.txt
I got the error:

404 : Not Found
You are requesting a page that does not exist!

It would be amazing if this was possible! :)
