Frequently used components for Python projects.

Project description


Frequently used components for Python projects.

PyPI Version Build Status Coverage Status Documentation Status Python Versions


All of the components in frequent have extensive code documentation (as well as extensive usage documentation and examples) and unit tests. The modules (and their associated unit tests) are entirely self-contained and depend solely on the standard library.

  • config: components providing global application configuration settings management and storage.

  • messaging: the foundations for building custom messaging frameworks.

  • repository: base class (and exception classes) for implementing the repository pattern for back-end agnostic object storage.

  • singleton: metaclass for creating singleton classes.

  • unit_of_work: base classes for implementing the unit of work pattern for transactional blocks.


You have a few options for installing/using frequent. The first is to install using your package manager of choice, pipenv for instance:

$ pipenv install frequent

However, taking a cue from the excellent boltons package, each component is self-contained in its respective file/folder allowing for easy vendorization. Components are not dependent on one another and rely solely on the standard library. This makes vendorization of a component as simple as copying just the file/folder for the component(s) that you need (same goes for the unit tests).


I found myself copying/re-writing certain components for my projects over and over again. This library is an attempt to take some of these components I find myself needing frequently (and re-writing too frequently) and package them up in a convenient and easy-to-use format.
