Side-loading calculator

[trombonekenny]

I just came from an in-person discussion about PrairieLearn, computer based testing, and calculators. The idea was floated around of including web-based calculators available through PL that could be launched aside a homework or exam. I could see the calculator option being a setting in the assessment where the instructor can decide if it's present, or maybe even the feature set(s) of the calculator.

Is anyone already using a HTML5 or javascript calculator like this? Are there open source copies projects we could install into PL? Or is this something we need/should/could write ourselves?

Some time ago I was playing around with adding an element with the desmos calculator, but I didn't go very far, since the node module I was using had some issues. If anyone is willing to play with it, you'd probably need to either download the files (probably not a good idea from maintainability point of view) or find a suitable node module.

Came across this while Googling. Here's how I did it in a question.html I wrote:

<pl-question-panel>

<div style="float: right;">
    <h5>Optional calculator</h5>
    <iframe src="https://www.desmos.com/fourfunction" width="200" height="350"></iframe>
</div>

<p>
You may not need it in this question, but you are permitted to
use the basic calculator provided to the right.

That works fine for homeworks, but may be an issue in exams with controlled Internet resources. Ideally all resources needed during an exam are under a single domain.
