# aws-lambda-env-modeler

> A Python library that uses Pydantic models to validate, parse, and manage environment variables in AWS Lambda functions.

aws-lambda-env-modeler simplifies environment variable management in AWS Lambda by leveraging Pydantic for type-safe parsing and validation. It provides a decorator to validate variables before handler execution and a global getter function for safe access anywhere in your code. Parsed models are cached for performance.

- Python 3.10 - 3.14
- Requires: pydantic >= 2.12.0, < 3
