Support for Javascript Frameworks

[binaryben]

Hey, this software looks amazing for writing academic reports. I'll definitely be using when I'm studying next.

There is this plugin that allows Svelte components to be used. Could inclusion of Javascript and JS Frameworks be considered as something to add with first party support and at a more generic level? I'd love to see React, Vue and Svelte supported in particular.

It would allow two main use cases:

1. Another way of creating new modules/extensions for use in generic (HTML based) documents
   • In particular, I am hoping to create a website like this awesome interactive maths learning website (for another topic) with Quarto
   • Some of the interactive components could be made in a JS Framework instead of Lua
2. Documentation for software projects
   • This already seems to have some level of support with the inclusion of Docusaurus sites as an output option

Not sure if this would be considered implemented by providing a way to use JS for Extensions or if it would be supported as a native supported language like Python and R are.

You should take a look at the Lua API's ability to include dependencies (described here: https://quarto.org/docs/extensions/lua-api.html#dependencies). This would allow you to e.g. enclose math in a special div that is handled specially by your JS code.

Net: you can do anything you want by including JS (w/ libraries as required) and then just applying the JS to portions of the document based on e.g. divs with special classes.

We have first-party support for Observable JS (https://quarto.org/docs/computations/ojs.html) because it aligns particularly well with scientific/technical communication. Using other frameworks is absolutely possible (as demonstrated w/ the Svelte plugin) but just requires a bit more work up front.
