Datasette 0.54: The annotated release notes
Datasette 0.54 is out today, with a number of foundational new features. As I’ve done for previous releases, here are the annotated release notes with some additional commentary.
[... 1,276 words]Drawing shapes on a map to query a SpatiaLite database (and other weeknotes)
This week I built a Datasette plugin that lets you query a database by drawing shapes on a map!
[... 950 words]Weeknotes: Still pretty distracted
Not a lot to report this week. U.S. politics continues to make it extremely difficult to focus on anything substantial.
[... 727 words]Weeknotes: datasette-export-notebook, PyInstaller packaged Datasette, CBSAs
What a terrible week. I’ve found it hard to concentrate on anything substantial. In a mostly futile attempt to distract myself from doomscrolling I’ve mainly been building some experimental output plugins, fiddling with PyInstaller and messing around with shapefiles.
[... 732 words]APIs from CSS without JavaScript: the datasette-css-properties plugin
I built a new Datasette plugin called datasette-css-properties. It’s very, very weird—it adds a .css output extension to Datasette which outputs the result of a SQL query using CSS custom property format. This means you can display the results of database queries using pure CSS and HTML, no JavaScript required!
datasette-css-properties (via) My new Datasette plugin defines a “.css” output format which returns the data from the query as a valid CSS stylesheet defining custom properties for each returned column. This means you can build a page using just HTML and CSS that consumes API data from Datasette, no JavaScript required! Whether this is a good idea or not is left as an exercise for the reader.
Weeknotes: A flurry of not-quite-finished features
My Christmas present to myself this year was to allow myself to spend a week working on stuff I found interesting, rather than sticking to the most important things. This may have been a mistake: it’s left me with a flurry of interesting but not-quite-finished features.

Replicating SQLite with rqlite (via) I’ve been trying out rqlite, a “lightweight, distributed relational database, which uses SQLite as its storage engine”. It’s written in Go and uses the Raft consensus algorithm to allow a cluster of nodes to elect a leader and replicate SQLite statements between them. By default it uses in-memory SQLite databases with an on-disk Raft replication log—here are my notes on running it in “on disk” mode as a way to run multiple Datasette processes against replicated SQLite database files.
Weeknotes: Datasette internals
I’ve been working on some fundamental changes to Datasette’s internal workings—they’re not quite ready for a release yet, but they’re shaping up in an interesting direction.
