Python-/flask-based web proxy for transforming a HXL dataset dynamically. Requires Python3.
User documentation is available at https://github.com/HXLStandard/hxl-proxy/wiki
Installation from PyPi:
pip install hxl-proxy
Installation from source:
python setup.py install
Running unit tests:
python setup.py test
To configure the proxy, make a copy of config.py.TEMPLATE (e.g. to config.py), and change its values as necessary. The environment variable HXL_PROXY_CONFIG should point to your local config file's location. More details appear below.
Choose and configure your input and output caches as needed, following the examples in the config template. You may need to create local directories or databases, depending on the caching backends you choose.
For mapping, the Proxy uses a collection of GeoJSON files hosted online. If you want to use a local copy (e.g. for offline demos), clone the GitHub repository at https://github.com/hxlstandard/p-codes and set the new base URL as the value of PCODE_BASE_URL. Note that the server serving the local copy must implement CORS, since the shapes get loaded on the browser side: https://www.w3.org/TR/cors/
Edit PCODE_COUNTRY_MAP if you'd like to make more countries available in the map dropdown menu.
Launching a local server (usually on http://127.0.0.1:5000):
python run-server.py
For web deployment, see the hxl-proxy.wsgi.TEMPLATE file and the flask documentation.
