Open edX Events from Hooks Extensions Framework (OEP-50_).

.. _OEP-50: https://open-edx-proposals.readthedocs.io/en/latest/oep-0050-hooks-extension-framework.html

Purpose

This repository implements the necessary tooling and definitions used by the Hooks Extension Framework to manage the events execution and extra tools.

Getting Started with Development

Please see the Open edX documentation for guidance on Python development <https://docs.openedx.org/en/latest/developers/how-tos/get-ready-for-python-dev.html>_ in this repo.

Deploying

The Open edX Events component is a Python library which doesn't need independent deployment. Therefore, its setup is reasonably straightforward. First, it needs to be added to your service requirements, and then it will be installed alongside requirements of the service.

If the service you intend to use is either the LMS or CMS, then the library is installed alongside their requirements since the Maple release.
