pypi-to-sqlite

PyPI Changelog Tests License

Load data about Python packages from PyPI into SQLite

Installation

Install this tool using pip:

pip install pypi-to-sqlite

Usage

To create a SQLite database with details of one or more packages, run:

pypi-to-sqlite pypi.db datasette sqlite-utils

You can also process JSON that you have previously saved to disk like so:

curl -o datasette.json https://pypi.org/pypi/datasette/json
pypi-to-sqlite pypi.db -f datasette.json

The tool will create three tables: packages, versions and releases. The full table schema is shown below.

To create the tables with a prefix, use --prefix prefix. For example:

pypi-to-sqlite pypi.db datasette --prefix pypi_

This will create tables called pypi_packages, pypi_versions and pypi_releases.

Demo

You can see examples of tables created using this tool running in Datasette here:

pypi-to-sqlite --help

Usage: pypi-to-sqlite [OPTIONS] DB_PATH [PACKAGE]...

  Load data about Python packages from PyPI into SQLite

  Usage example:

      pypi-to-sqlite pypy.db datasette sqlite-utils

  Use -f to load data from a JSON file instead:

      pypi-to-sqlite pypy.db -f datasette.json

  Created tables will be packages, versions and releases

  To create tables called pypi_packages, pypi_versions, pypi_releases use
  --prefix pypi_:

      pypi-to-sqlite pypy.db datasette sqlite-utils --prefix pypi_

Options:
  --version            Show the version and exit.
  -f, --file FILENAME  Import JSON from this file
  -d, --delay FLOAT    Wait this many seconds between requests
  --prefix TEXT        Prefix to use for the created database tables
  --help               Show this message and exit.

Development

To contribute to this tool, first checkout the code. Then create a new virtual environment:

cd pypi-to-sqlite
python -m venv venv
source venv/bin/activate

Now install the dependencies and test dependencies:

pip install -e '.[test]'

To run the tests:

pytest
