In Python development, we often face a tricky problem: when upgrading third-party libraries or Python versions, API changes can cause existing code to break. These compatibility issues not only consume development time but can also prevent projects from adopting safer and more efficient library versions in a timely manner.

This is the pain point that Modshim aims to solve.

What is modshim?

modshim is an innovative Python package that provides a lightweight method for creating module shim layers, allowing you to elegantly handle API incompatibility issues without modifying your original code.

Imagine you’re using a popular data processing library, but when upgrading to a new version, you discover that key functions have been renamed or parameter signatures have changed. Traditionally, you’d have to modify every import and call throughout your codebase. With modshim, you only need to define compatibility rules in one place, and it handles the rest automatically.
