And ya, it’s been a minute (or 214 days) since the last Plot release. We’ll get back to soon and ship a 1.0 release. Been busy between Canvases and Notebooks 2.0.

Observable Notebook Kit & Desktop 1.4 now support TypeScript cells, along with TypeScript for Node.js data loader cells. (Just type stripping, but greatly helps interoperability.)

A small but significantly useful victory: I got file association working with Observable Desktop.

Big fan of @observablehq.com and since their preview release of Observable Notebooks 2.0 my team at Fora Health have integrated Notebook Kit into our app. Works really well so far. Quick demo ⬇️

Oops, seems I broke sign-in in yesterday’s Observable Desktop 1.1.0, but it should be fixed now in 1.1.1. Was it broken for you? Is it fixed now? Please give it a try and let me know. observablehq.com/notebook-kit...

I would love to see that! We’re not using Arrow yet to serialize the results (instead using JSON array-of-objects, mostly because it’s easy), but I’m planning on switching to Arrow tables in memory and possibly Parquet for files in the future.

Wow, that was fast. 🏎️💨 Nice work! Also a tip: SQL cells declare their own DatabaseClient internally when you use the database attribute (unless you set it to something like `var:db`) so no need to declare one in JavaScript unless you want to use it in JavaScript.
