easyconfig

Easy application configuration with yaml files

Description

Easyconfig simplifies the configuration management for (small) applications.

Validation and parsing of the configuration file is done through pydantic and easyconfig builds on that. It's possible to use all pydantic features and model features so every exotic use case should be covered. If you have previously worked with pydantic you should feel right at home

Features

• Default .yml file generation
• Environment variable expansion
• Support for docker secrets
• Callbacks when values of the configuration change

Why not pydantic settings

A pydantic settings object is a non-mutable object. With easyconfig you can create a global configuration and just import it into your modules. When your application starts you can read the configuration e.g. from a settings file and the object values will change the values accordingly.

Additionally, easyconfig can create a default configuration file with the specified default values and comments of the pydantic models. That way the users can have some guidance how to change the program behaviour.

Environment Variable Expansion

It's possible to use environment variable or files for expansion. Easyconfig will load all values
