A minimal Python library to validate environment variables at startup. Zero dependencies.
Project description
envgate
A minimal Python library to validate environment variables at startup. Zero dependencies.
Why?
Instead of your app crashing at runtime because DATABASE_URL is missing,
envgate validates everything at startup and tells you exactly what's wrong.
Installation
pip install envgate
Quick Start
from envgate import get_env, validate
# Get a single variable with type coercion
port = get_env("PORT", type="int", default=8000)
debug = get_env("DEBUG", type="bool", default=False)
# Or validate multiple variables at once
config = validate({
"DATABASE_URL": {"type": "str"},
"REDIS_URL": {"type": "str"},
"PORT": {"type": "int", "default": 8000},
"DEBUG": {"type": "bool", "default": False},
})
If DATABASE_URL is missing:
envgate.exceptions.MissingEnvVarError: Environment variable 'DATABASE_URL' is not set.
