Subsume JSON a.k.a. JSON ⊂ ECMAScript (via) TIL that JSON isn’t a subset of ECMAScript after all! “In ES2018, ECMAScript string literals couldn’t contain unescaped U+2028 LINE SEPARATOR and U+2029 PARAGRAPH SEPARATOR characters, because they are considered to be line terminators even in that context.” # 15th August 2019, 10:30 am

json-flatten. A little Python library I wrote that attempts to flatten a JSON object into a set of key/value pairs suitable for transmitting in a query string or using to construct an HTML form. I first wrote this back in 2015 as a Gist—I’ve reconstructed the Gist commit history in a new repository and shipped it to PyPI. # 22nd June 2019, 4:51 am

paginate-json (via) I released a fun tiny utility: paginate-json, which knows how to paginate through JSON APIs that use the HTTP Link header for pagination. I built it so I could pull data from the GitHub API and pipe it directly into SQLite via sqlite-utils. # 12th June 2019, 3:22 pm

quicktype code generator for Python. Really interesting tool: give it an example JSON document and it will code-generate the equivalent set of Python classes (with type annotations) instantly in your browser. It also accepts input in JSON Schema or TypeScript and can generate code in 18 different languages. # 14th May 2019, 11:35 pm

zson (via) “ZSON is a PostgreSQL extension for transparent JSONB compression. Compression is based on a shared dictionary of strings most frequently used in specific JSONB documents [...] In some cases ZSON can save half of your disk space and give you about 10% more TPS.” # 2nd April 2019, 9:26 pm

Datasette 0.27 (via) The latest release of Datasette introduces an option to output tables and SQL query results as newline-delimited JSON—plus a new “datasette plugins” command for listing available plugins. # 1st February 2019, 4:39 am
