⚒️ Start contributing

I wanted to make the setup of the environment as easy as possible. To start the environment you need the following prerequisites:

Prerequisites

• bash (+4.3)
• docker (+17.05)
• docker-compose (+1.16.1)
• docker-py (+2.2.1)
• ansible (+2.3)

Start environment

You only (fingers crossed) need to execute the following to start the environment:

make start-containers

Architecture and patterns

Principally I used some DDD concepts (like value objects, entities, and so on) and also CQS whose objective is to separate commands from queries.

The structure of the code is the following:

• pepy/application: here is where all the commands and the queries are located.
• pepy/domain: domain objects like entities, exceptions, and value objects.
• pepy/infrastructure: infrastructure components like the implementation of the repository class like DB or BigQuery, the Flask web application, the container, and so on.
  • pepy/infrastructure/cli: the command line programs.
  • pepy/infrastructure/container: config files and the dependency injection manager.
  • pepy/infrastructure/api: the api endpoints controller.

FAQ

Where the downloads come from?

The data is retrieved from the official BigQuery repository: https://packaging.python.org/guides/analyzing-pypi-package-downloads/

When the data is updated?

There is a cron that runs every day at 5 pm UTC that retrieves all the new downloads from the previous day.
