crashbytes-envguard
Lightweight environment variable validation with schema, type coercion, and .env loading.
Install
pip install crashbytes-envguard
Usage
from crashbytes_envguard import create_env, s
env = create_env({
"PORT": s.port().default(8080),
"DB_URL": s.url(),
"DEBUG": s.boolean().default(False),
"LOG_LEVEL": s.string().choices("debug", "info", "warn", "error").default("info"),
})
print(env["PORT"]) # 8080 (int, type-coerced)
print(env["DB_URL"]) # "https://..." (validated)
print(env["DEBUG"]) # False (bool, type-coerced)
Fails fast with all errors at once:
EnvError: Environment validation failed:
- DB_URL: required but not set
- PORT: must be >= 1 (got 0)
