evp-ts

Lightweight environment variable parser for TypeScript, inspired by Zod and Haskell's EVP. Current stable version 1.1.1 is actively maintained with regular releases. Supports nested object parsing, type inference, secret masking, default values, optional fields, and dotenv-style help generation. Key differentiators: low dependency footprint, comprehensive error reporting that continues parsing all variables, and explicit logging with secret hashing. Alternative to dotenv with stronger typing and validation, but less mature ecosystem.
