Datasette is an open source tool for exploring and publishing data.

The Accountability Project Datasettes. The Accountability Project “curates, standardizes and indexes public data to give journalists, researchers and others a simple way to search across otherwise siloed records”—they have a wide range of useful data, and they’ve started experimenting with Datasette to provide SQL access to a subset of the information that they have collected.
Weeknotes: Datasette and Git scraping at NICAR, VaccinateCA
This week I virtually attended the NICAR data journalism conference and made a ton of progress on the Django backend for VaccinateCA (see last week).

This week I got involved with the VaccinateCA effort. We are trying to end the pandemic a little earlier, by building the most accurate database possible of vaccination locations and availability in California.
[... 1,154 words]Fuzzy Name Matching in Postgres. Paul Ramsey describes how to implement fuzzy name matching in PostgreSQL using the fuzzystrmatch extension and its levenshtein() and soundex() functions, plus functional indexes to query against indexed soundex first and then apply slower Levenshtein. The same tricks should also work against SQLite using the datasette-jellyfish plugin.
Cross-database queries in SQLite (and weeknotes)
I released Datasette 0.55 and sqlite-utils 3.6 this week with a common theme across both releases: supporting cross-database joins.
[... 720 words]Open source projects: consider running office hours
Back in December I decided to try something new for my Datasette open source project: Datasette Office Hours. The idea is simple: anyone can book a 25 minute conversation with me on a Friday to talk about the project. I’m interested in talking to people who are using Datasette, or who are considering using it, or who just want to have a chat.
[... 786 words]Weeknotes: Finally, an intro video for Datasette
My big project this week was this Video introduction to Datasette and sqlite-utils. I recorded the video a few weeks ago in advance of FOSDEM, but this week I put together the annotated version. I’m really happy with it, and I’ve added it to the datasette.io homepage as a starting point for helping people understand the project.
[... 690 words]Video introduction to Datasette and sqlite-utils
I put together a 17 minute video introduction to Datasette and sqlite-utils for FOSDEM 2021, showing how you can use Datasette to explore data, and demonstrating using the sqlite-utils command-line tool to convert a CSV file into a SQLite database, and then publish it using datasette publish. Here’s the video, plus annotated screen captures with further links and commentary.
Weeknotes: Mostly messing around with map tiles
Most of what I worked on this week was covered in Serving map tiles from SQLite with MBTiles and datasette-tiles. I built two new plugins: datasette-tiles for serving map tiles, and datasette-basemap which bundles map tiles for zoom levels 0-6 of OpenStreetMap. I also released download-tiles for downloading tiles and bundling them into an MBTiles database.
[... 350 words]Serving map tiles from SQLite with MBTiles and datasette-tiles
Working on datasette-leaflet last week re-kindled my interest in using Datasette as a GIS (Geographic Information System) platform. SQLite already has strong GIS functionality in the form of SpatiaLite and datasette-cluster-map is currently the most downloaded plugin. Most importantly, maps are fun!
[... 1,334 words]JMeter Result Analysis using Datasette (via) NaveenKumar Namachivayam wrote a detailed tutorial on using Datasette (on Windows) and csvs-to-sqlite to analyze the results of JMeter performance test runs and then publish them online using Vercel.
Weeknotes: datasette-leaflet, datasette-plugin cookiecutter upgrades
This week I shipped Datasette 0.54, sent out the latest Datasette Newsletter and then mostly worked on follow-up projects.
[... 552 words]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.
[... 760 words]Datasette Weekly: Official project website for Datasette, building a search engine with Dogsheep Beta, sqlite-utils analyze-tables (via) Volume 5 of the Datasette Weekly-ish newsletter.
Building a search engine for datasette.io
This week I added a search engine to datasette.io, using the search indexing tool I’ve been building for Dogsheep.
[... 1,391 words]datasette.io, an official project website for Datasette
This week I launched datasette.io—the new official project website for Datasette.
[... 1,971 words]datasette.io (via) Datasette finally has an official project website, three years after the first release of the software. I built it using Datasette, with custom templates to define the various pages. The site includes news, latest releases, example sites and a new searchable plugin directory.
Weeknotes: github-to-sqlite workflows, datasette-ripgrep enhancements, Datasette 0.52
This week: Improvements to datasette-ripgrep, github-to-sqlite and datasette-graphql, plus Datasette 0.52 and a flurry of dot-releases.
New for AWS Lambda – Container Image Support. “You can now package and deploy Lambda functions as container images of up to 10 GB in size”—can’t wait to try this out with Datasette.
Datasette Weekly volume 4. Datasette Office Hours, Personal Data Warehouses, datasette-ripgrep, datasette-indieauth, Datasette Client for Observable and more.
Datasette Office Hours (via) I’ve decided to try running Datasette Office Hours every Friday. If you’d like to chat with me over Zoom about the project for 20 minutes for any reason at all you can grab a slot here using Calendly.
Datasette 0.52. A relatively small release—it has a new plugin hook (database_actions(), for adding links to a new database actions menu), renames the --config option to --setting and adds a new “datasette publish cloudrun --apt-get-install” option.
