You can find both apps (color chooser and CVD simulations) on the class website, under Resources.

Great work, thanks! Do you plan on porting the palette creator app as well?

And how extensive are the changes? Does it make sense to integrate the shinylive versions in the colorspace package as well?

I'm not sure I'll port the palette creator app because I don't think it fits into my class and so I don't want to confuse students with an app they don't know what to do with. 1/

The changes to port an app are pretty minimal. In theory, you just have to run shinylive::export() on the app dir.

In practice, I did three types of changes: 1. Resolve incompatibilities; 2. Fix folder structure for web assets; 3. Tweak UI. 2/

Incompatibilities: Some existing R packages don't currently work in webr. Most importantly RCurl. There was an RCurl call I had to replace with a call from base64enc. Not a big deal. 3/
