Regarding "inject custom JavaScript to be run on kernel startup", I tried to add some script in post.js. If the script uses no external packages, it works well. For "await import()" is not allowed in post.js in building, so far, I couldn't find a way to use external packages. For example, const {default: OpenAI} = await import('https://cdn.jsdelivr.net/npm/openai@4.26.0/+esm'); caused SyntaxError: Unexpected token ("import").
Any suggestions?

xeus-javascript
opens the door for quite some interesting use cases. For example it could be reused for making custom JavaScript kernels with a set of libraries already preloaded.Looks like we would need a way to:
A concrete example would be for the p5 kernel: https://github.com/jupyterlite/p5-kernel Currently this kernel is a bit tedious to maintain, and would benefit from the features offered by
xeus-javascript
.Having such kernel compared to using a generic JavaScript kernel would still be useful, because someone authoring a p5 sketch could directly use global variables (like the
setup()
anddraw()
functions, or other globals likeTWO_PI
orDEGREES
) provided by the p5 library, without having to import the library from a CDN.
