Development

Codebase

The pygeoapi codebase exists at https://github.com/geopython/pygeoapi.

Testing

pygeoapi uses pytest for managing its automated tests. Tests exist in /tests and are developed for providers, formatters, processes, as well as the overall API.

Tests can be run locally as part of development workflow. They are also run on pygeoapi’s GitHub Actions setup against all commits and pull requests to the code repository.

To run all tests, simply run pytest in the repository. To run a specific test file, run pytest tests/test_api.py, for example.

Working with Spatialite on OSX

Using pyenv

It is common among OSX developers to use the package manager homebrew for the installation of pyenv to being able to manage multiple versions of Python. They can encounter errors about the load of some SQLite extensions that pygeoapi uses for handling spatial data formats. In order to run properly the server you are required to follow these steps below carefully.

Make Homebrew and pyenv play nicely together:

# see https://github.com/pyenv/pyenv/issues/106
alias brew='env PATH=${PATH//$(pyenv root)\/shims:/} brew'

Install python with the option to enable SQLite extensions:

LDFLAGS="-L/usr/local/opt/sqlite/lib -L/usr/local/opt/zlib/lib" CPPFLAGS="-I/usr/local/opt/sqlite/include -I/usr/local/opt/zlib/include" PYTHON_CONFIGURE_OPTS="--enable-loadable-sqlite-extensions" pyenv install 3.7.6

Configure SQLite from Homebrew over that one shipped with the OS:

export PATH="/usr/local/opt/sqlite/bin:$PATH"

Install Spatialite from Homebrew:

brew update
brew install spatialite-tools
brew libspatialite

Set the variable for the Spatialite library under OSX:

SPATIALITE_LIBRARY_PATH=/usr/local/lib/mod_spatialite.dylib
