Weeknotes: cookiecutter templates, better plugin documentation, sqlite-generate

I spent this week spreading myself between a bunch of smaller projects, and finally getting familiar with cookiecutter. I wrote about my datasette-plugin cookiecutter template earlier in the week; here’s what else I’ve been working on.

datasette-block-robots. Another little Datasette plugin: this one adds a /robots.txt page with “Disallow: /” to block all indexing of a Datasette instance from respectable search engine crawlers. I built this in less than ten minutes from idea to deploy to PyPI thanks to the datasette-plugin cookiecutter template. # 23rd June 2020, 3:28 am

A cookiecutter template for writing Datasette plugins

Datasette’s plugin system is one of the most interesting parts of the entire project. As I explained to Matt Asay in this interview, the great thing about plugins is that Datasette can gain new functionality overnight without me even having to review a pull request. I just need to get more people to write them!

Weeknotes: Datasette alphas for testing new plugin hooks

A relatively quiet week this week, compared to last week’s massive push to ship Datasette 0.44 with authentication, permissions and writable canned queries. I can now ship alpha releases, such as today’s Datasette 0.45a1, which means I can preview new plugin features before they are completely ready and stable.

Datasette 0.44: The annotated release notes

I just released Datasette 0.44 to PyPI. With 128 commits since 0.43 this is the biggest release in a long time—and likely the last major release of new features before Datasette 1.0.

Serving photos locally with datasette-media. datasette-media is a new Datasette plugin which can serve static files from disk in response to a configured SQL query that maps incoming URL parameters to a path to a file. I built it so I could run dogsheep-photos locally on my laptop and serve up thumbnails of images that match particular queries. I’ve added documentation to the dogsheep-photos README explaining how to use datasette-media, datasette-json-html and datasette-template-sql to create custom interfaces onto Apple Photos data on your machine. # 26th May 2020, 3:53 pm

Weeknotes: COVID-19 numbers in Datasette

COVID-19, the disease caused by the novel coronavirus, gets more terrifying every day. Johns Hopkins Center for Systems Science and Engineering (CSSE) have been collating data about the spread of the disease and publishing it as CSV files on GitHub.

datasette-search-all: a new plugin for searching multiple Datasette tables at once

I just released a new plugin for Datasette, and it’s pretty fun. datasette-search-all is a plugin written mostly in JavaScript that executes the same search query against every searchable table in every database connected to your Datasette instance.

Weeknotes: Datasette Writes

As discussed previously, the biggest hole in Datasette’s feature set at the moment involves writing to the database.

Building a sitemap.xml with a one-off Datasette plugin

One of the fun things about launching a new website is re-learning what it takes to promote a website from scratch on the modern web. I’ve been thoroughly enjoying using Niche Museums as an excuse to explore 2020-era SEO.

Datasette: publish_subcommand hook + default plugins mechanism, used for publish heroku/now (via) I just landed a new plugin hook to Datasette master: publish_subcommand, which lets you define new publisher subcommands for the “datasette publish” CLI tool in addition to Heroku and Zeit Now. As part of this I’ve refactored the heroku/now publisher implementations into two default plugins that ship as part of Datasette—I hope to use this pattern for other core functionality in the future. # 26th July 2018, 5:27 am

datasette-vega (via) I wrote a visualization plugin for Datasette that uses the excellent Vega “visualization grammar” library to provide bar, line and scatter charts configurable against any Datasette table or SQL query. # 29th June 2018, 3 pm

Datasette 0.19: Plugins Documentation (via) I’ve released the first preview of Datasette’s new plugin support, which uses the pluggy package originally developed for py.test. So far the only two plugin hooks are for SQLite connection creation (allowing custom SQL functions to be registered) and Jinja2 template environment initialization (for custom template tags), but this release is mainly about exercising the plugin registration mechanism and starting to gather feedback. Lots more to come. # 17th April 2018, 3:59 am
