The sdx-downstream app is used within the Office for National Statistics (ONS) for consuming decrypted Survey Data Exchange (SDX) Surveys from sdx-store and delivering them to downstream environments e.g. Common Software.

This application presently installs required packages from requirements files:

• requirements.txt: packages for the application, with hashes for all packages: see https://pypi.org/project/hashin/
• test-requirements.txt: packages for testing and linting

It's also best to use pyenv and pyenv-virtualenv, to build in a virtual environment with the currently recommended version of Python. To install these, see:

• https://github.com/pyenv/pyenv
• https://github.com/pyenv/pyenv-virtualenv
• (Note that the homebrew version of pyenv is easiest to install, but can lag behind the latest release of Python.)

Once your virtual environment is set, install the requirements:

$ make build

To test, first run make build as above, then run:

$ make test

It's also possible to install within a container using docker. From the sdx-downstream directory:

$ docker build -t sdx-downstream .

The following environment variables can be set:

sdx-downstream works as a single consumer which exposes no endpoints. The best way to test its behaviour is to start it within a docker-compose setup and trigger the consumer through the console.
