Trying to load a npm module (Ruffle - [Using Ruffle · ruffle-rs/ruffle Wiki · GitHub](https://github.com/ruffle-rs/ruffle/wiki/Using-Ruffle#javascript-api)) throws an error:

```auto
 ChunkLoadError: Loading chunk 966 failed.
(error: https://observablehq.com/@atiro/core.ruffle.14afbe2b2ea587f28d56.js)

```

I think I’m pushing things probably trying to load this emulator within a notebook, but any obvious fixes ?

I’ve sent you a suggestion to load the wasm file. It seems to be working but I can’t confirm while the swf file is missing.

I’ve created an example here:

for comparison, my suggestion is here [Leonardo Canal Challenge / Fil / Observable](https://observablehq.com/@fil/leonardo-canal-challenge-suggestion) ; I didn’t know of ruffle-mirror, which seems to be better than my fiddling with the config.

I’ve updated [my notebook](https://observablehq.com/@mootari/ruffle-js) to include a splash screen and download progress, implemented via `XMLHttpRequest`.
