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
Yesterday I described the new sqlite-utils transform mechanism for applying SQLite table transformations that go beyond those supported by
ALTER TABLE. The other new feature in sqlite-utils 2.20 builds on that capability to allow you to refactor a database table by extracting columns into separate tables. I’ve called it sqlite-utils extract.
This week I built a geospatial search engine for protected areas in California, shipped datasette-graphql 1.0 and started working towards the next milestone for Datasette Cloud.[... 1099 words]
This week I helped Natalie launch Rocky Beaches, shipped Datasette 0.48 and several releases of
datasette-graphql, upgraded the CSRF protection for
datasette-upload-csvs and figured out how to get a commit log of changes to my blog by backing up its database to a GitHub repository.
This week I’ve been working on making Datasette easier to install, plus wide-ranging improvements to the Datasette GraphQL plugin.[... 1009 words]
This week I’ve mostly been building datasette-graphql, a plugin that adds GraphQL query support to Datasette.[... 1249 words]
GitHub quietly released a new feature at some point in the past few days: profile READMEs. Create a repository with the same name as your GitHub account (in my case that’s github.com/simonw/simonw), add a
README.md to it and GitHub will render the contents at the top of your personal profile page—for me that’s github.com/simonw
How Super Graph compiles GraphQL to a single SQL query. Super Graph is a GraphQL server that compiles arbitrarily nested GraphQL queries to “a single fast SQL query”. I’ve always wondered how that could possible work, so I asked author Vikram Rangnekar for an example of a compiled query—it turns out it uses a brilliant sequence of JSON aggregations to glue together results from nested subqueries and left outer joins. # 16th April 2020, 10:52 pm
SQL is a better API language than GraphQL – Convince me otherwise (via) A dumb tweet I posted this morning blew up today and ended up on the Hacker News homepage. # 16th April 2020, 10:44 pm
PostGraphile: Production Considerations. PostGraphile is a tool for building a GraphQL API on top of an existing PostgreSQL schema. Their “production considerations” documentation is particularly interesting because it directly addresses some of my biggest worries about GraphQL: the potential for someone to craft an expensive query that ties up server resources. PostGraphile suggests a number of techniques for avoiding this, including a statement timeout, a query allowlist, pagination caps and (in their “pro” version) a cost limit that uses a calculated cost score for the query. # 27th March 2020, 1:22 am
Select Transform: JSON Template over JSON (via) A barrage of interesting ideas here. Having clients transmit up a JSON template which is then executed against data on the server and used to return exactly the data the client needs is just one of them (significant overlap with GraphQL there). # 18th October 2017, 5:12 pm
