Descripción
Problem:
When trying to import a local module for OJS as outlined here when server: shiny, an error occurs and the module cannot be used. The module is found, otherwise the error will occur on initial build and the render will fail, but it is unable to be imported. This does not happen if the shiny server is not used. It would be useful to be able to store OJS code (such as functions that can make plots) as a .qmd module and import it into a quarto document running with a shiny server to feed in the data.
Currently this is the error that occurs:
Error: error loading dynamically imported module Loading module from “http://localhost:6366/square.js” was blocked because of a disallowed MIME type (“text/html”)
Minimal Example:
square.js:
export function square(x) { return x * x; }
This works:
---
title: "Module Import Test"
format: html
---
```{ojs}
//| echo: true
//| output: true
import { square } from "./square.js";
square(5);
```
This does not:
---
title: "Module Import Test"
format: html
server: shiny
---
```{ojs}
//| echo: true
//| output: true
import { square } from "./square.js" // This recieves an error and square is undefined.
square(x)
```
```{ojs}
x * x // This code is able to run perfectly fine
```
```{r}
#| context: server
#| echo: true
x <- reactive(5)
ojs_define(x)
```

Línea de trabajo
Reproduce the failure with square.js and the minimal Quarto document using server: shiny, comparing it with the working non-Shiny document. Start by tracing how the local JavaScript module is served during Shiny rendering; done means the local OJS import loads and square(5) works in the Shiny document without the MIME-type error.
