Project Overview: PePy
PePy is an insightful platform designed to provide detailed statistics about Python packages. It is an essential tool for Python developers who are eager to monitor the performance and reach of their packages within the community. The official website can be accessed at pepy.tech, and it includes both backend and frontend repositories. The backend service, which this introduction focuses on, forms the backbone of the PePy website's operations.
The Purpose of PePy
The primary aim of PePy is to offer a comprehensive view of the download statistics for Python packages. By aggregating and presenting data, it helps developers understand the impact and popularity of their projects, which is crucial for maintaining and improving open-source software.
Contribution and Sponsorship
The sustainability of PePy is made possible through community support and generous sponsorships. Notably, companies such as DigitalOcean and individuals like Samuel Colvin, Seth Michael Larson, Luciano Bello, and Pavel Dmytrenko have committed support to keep the platform operational. Their contributions underscore the collaborative nature of the open-source community.
Getting Started with Development
PePy encourages contributions from the open-source community. Setting up a development environment is straightforward, requiring a few prerequisites:
- Bash version 4.3 or higher
- Docker version 17.05 or higher
- Docker Compose version 1.16.1 or higher
- Docker-py version 2.2.1 or higher
- Ansible version 2.3 or higher
Prospective contributors can start the environment with a simple command:
make start-containers
Project Architecture and Design Patterns
PePy employs Domain-Driven Design (DDD) along with the Command Query Separation (CQS) pattern to clearly delineate commands from queries. This logical architecture is structured into several components:
- Application Layer: Contains all commands and queries.
- Domain: Houses domain objects, including entities, exceptions, and value objects.
- Infrastructure: Manages components such as database implementations, web applications using Flask, and APIs.
- CLI: Command-line interface programs.
- Container: Configurations and dependency management.
- API: Endpoint controllers for interfacing with user requests.
Frequently Asked Questions
Where does the download data originate from?
The download data comes from the official Python Packaging Authority (PyPA) BigQuery dataset, which provides comprehensive download statistics for Python packages.
How frequently is the data updated?
Updates occur daily with a cron job that retrieves data at 5 pm UTC. This ensures that download figures are current, reflecting the latest activity from the previous day.
Licensing
PePy is available under the MIT license, promoting open access and collaboration by allowing anyone to use, modify, and distribute the software.
In summary, PePy is a pivotal tool for Python developers looking to analyze the performance of their packages. Its open-source nature and ease of setup invite vast collaboration, making it a valuable resource in the Python community.
