Znv is a TypeScript library for type-safe environment variable parsing and validation in Node.js using Zod schemas. It allows developers to define environment variable schemas with defaults, descriptions, and validation rules, then export validated, type-safe values for use in their applications. The library automatically coerces string environment variables to appropriate types, provides environment-specific defaults, and aggregates validation errors with helpful context. It's designed for Node.js applications that need robust configuration management through environment variables, particularly those using TypeScript and Zod for type safety.
