The official Python VSCode extension from Microsoft is itself a further development of that one (indeed, you can still see that it's a fork on GitHub: https://github.com/microsoft/vscode-python).
After some light testing, this seems to work really well. I've had issues with other Javascript kernels for Jupyter and I personally don't care for the UX of Observable, so this is exciting.
Nothing huge, just don't personally care for evaluated output above the cell. Kinda breaks all the conventions of the command line, Jupyter, etc. Not that I couldn't get used to it, but originally Observable output below the cell but then switched in some update and I never really went back. Such a minor little pet peeve, I know.
I realise this is probably obvious to most people who're familiar with the author's work, but I was looking at the README trying to figure out if this is just a VS Code thing or not. It doesn't say (though it has screenshots of VS Code, nothing in the README says it's a VS Code extension). It does say it in the "about" section of the repo, which I rarely actually look at on Github.
Something I've experimented a bit with in the past is having something like Storybook for API modules. Rather than jumping out to postman, you could just have your notebook that calls your API functions. So far the stumbling block is always ES Modules. Usually the client code uses them and Node always makes them a pain to deal with. Hopefully the situation will be better in another couple of years.
not sure myself, but could be useful to make some quick visualization of some database. often I just want to know some random stuff, so I'll use a SQL query, this looks like a neat way to do that, get some graphs too.
This looks very cool. Especially the ploty integration.
As a frontend JS dev - I feel like I need a good walkthrough blog post to really understand how this works - the REPL/notebook concept is new to me but it's instantly attractive
I always wondered why no one made a better node.js repl. I wish there was something like ipython for nodejs.
