Weeknotes: tableau-to-sqlite, django-sql-dashboard

This week I started a limited production run of my new backend for Vaccinate CA calling, built a tableau-to-sqlite import tool and started working on a subset of Datasette for PostgreSQL and Django called django-sql-dashboard.

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.

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 homepage as a starting point for helping people understand the project.

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.

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!

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.

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!

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.

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!

[... 891 words]

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. # 7th January 2021, 7:42 pm

sqlite-utils 3.2 (via) As discussed in my weeknotes yesterday, this is the release of sqlite-utils that adds the new “cached table counts via triggers” mechanism. # 3rd January 2021, 9:25 pm

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.

Building a search engine for

This week I added a search engine to, using the search indexing tool I’ve been building for Dogsheep.

[... 1391 words], an official project website for Datasette

This week I launched—the new official project website for Datasette.

[... 1956 words] (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. # 11th December 2020, 4:11 am

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.

[... 1123 words]

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. # 29th November 2020, 12:56 am

datasette-ripgrep: deploy a regular expression search engine for your source code

This week I built datasette-ripgrep—a web application for running regular expression searches against source code, built on top of the amazing ripgrep command-line tool.

Weeknotes: datasette-indieauth, datasette-graphql, PyCon Argentina

Last week’s weeknotes took the form of my Personal Data Warehouses: Reclaiming Your Data talk write-up, which represented most of what I got done that week. This week I mainly worked on datasette-indieauth, but I also gave a keynote at PyCon Argentina and released a version of datasette-graphql with a small security fix.

[... 718 words]

datasette-graphql 1.2 (via) A new release of the datasette-graphql plugin, fixing a minor security flaw: previous versions of the plugin could expose the schema (but not the actual data) of tables in databases that were otherwise protected by Datasette’s permission system. # 21st November 2020, 10:21 pm

Security vulnerability in datasette-indieauth: Implementation trusts the “me” field returned by the authorization server without verifying it. I spotted a critical security vulnerability in my new datasette-indieauth plugin: it accepted the “me” profile URL value returned from the authorization server in the final step of the IndieAuth flow without verifying it, which means a malicious server could imitate any user. I’ve shipped 1.1 with a fix and posted a security advisory to the GitHub repository. # 19th November 2020, 9:14 pm

Implementing IndieAuth for Datasette

IndieAuth is a spiritual successor to OpenID, developed and maintained by the IndieWeb community and based on OAuth 2. This weekend I attended IndieWebCamp East Coast and was inspired to try my hand at an implementation. datasette-indieauth is the result, a new plugin which enables IndieAuth logins to a Datasette instance.

Datasette 0.51 (plus weeknotes)

I shipped Datasette 0.51 today, with a new visual design, plugin hooks for adding navigation options, better handling of binary data, URL building utility methods and better support for running Datasette behind a proxy. It’s a lot of stuff! Here are the annotated release notes.

Weeknotes: incremental improvements

I’ve been writing my talk for PyCon Argentina this week, which has proved surprisingly time consuming. I hope to have that wrapped up soon—I’m pre-recording it, which it turns out is much more work than preparing a talk to stream live.

Weeknotes: evernote-to-sqlite, Datasette Weekly, scrapers, csv-diff, sqlite-utils

This week I built evernote-to-sqlite (see Building an Evernote to SQLite exporter), launched the Datasette Weekly newsletter, worked on some scrapers and pushed out some small improvements to several other projects.

Building an Evernote to SQLite exporter

I’ve been using Evernote for over a decade, and I’ve long wanted to export my data from it so I can do interesting things with it.

[... 1879 words]

xml-analyser. In building evernote-to-sqlite I dusted off an ancient (2009) project I built that scans through an XML file and provides a summary of what elements are present in the document and how they relate to each other. I’ve now packaged it up as a CLI app and published it on PyPI. # 12th October 2020, 12:41 am

evernote-to-sqlite (via) The latest tool in my Dogsheep series of utilities for personal analytics: evernote-to-sqlite takes Evernote note exports en their ENEX XML format and loads them into a SQLite database. Embedded images are loaded into a BLOB column and the output of their cloud-based OCR system is added to a full-text search index. Notes have a latitude and longitude which means you can visualize your notes on a map using Datasette and datasette-cluster-map. # 12th October 2020, 12:38 am

Datasette Weekly: Datasette 0.50, git scraping, extracting columns (via) The first edition of the new Datasette Weekly newsletter—covering Datasette 0.50, Git scraping, extracting columns with sqlite-utils and featuring datasette-graphql as the first “plugin of the week” # 10th October 2020, 9 pm
