Why?

This is originally designed for merge multiple configurations in different running environment such as production or stage.

As a node.js developer, package config and lodash are very handy for me. This package is the base of a python-version config package.

In a normal project, there is usually a copy of default configuration, but when we deploy it, some configurations differ from default ones like database address. So a handy configuration-loading package is supposed to load right configurations according to the running environment.
