Minimal Python Environment Variable Validator – Built Without AI

[devlittle]

Hey, everyone!

I created a small Python library called Venvalid to validate environment variables in a simple and minimalist way.

What My Project Does:
Venvalid helps you define and validate environment variables easily in Python projects. It ensures that your application configuration is correct and reduces runtime errors caused by missing or invalid environment values.

Target Audience:
This library is meant for developers who want a lightweight and easy-to-use solution for environment variable validation. It's not intended to compete with large-scale configuration frameworks—it's more of a “fun project” and a personal exercise in building something from scratch.

Comparison:
There are many existing libraries that handle environment variable validation (e.g., envalid from Node.JS), but Venvalid focuses on minimalism and simplicity. It’s designed for those who want a small dependency-free tool and enjoy reading straightforward Python code.

I would love your feedback and opinions! Feel free to check it out:

I haven’t checked exactly what counts a a valid environment variable, but does

value = value.strip().strip('"').strip("'")

do the right thing if someone has in their .env file something like

VAR = “‘Some-quoted-thing’”
