Env Guard v2

Overview

Env Guard v2 is an enhanced CLI tool designed to help developers manage and verify environment variables in Node.js projects. It ensures .env files are properly configured, checks for missing or unused variables, and provides auto-fix options to streamline development.

Features

• Check for Missing .env and .env.example Files: Ensures the necessary environment files exist.
• Auto-Fix Missing Variables: Adds missing variables from .env.example to .env automatically.
• Export .env to JSON: Converts .env file into a structured env.json format.
• Detect Unused Variables: Identifies variables in .env that are not referenced in .env.example.
• Initialize .env Files: Creates empty .env and .env.example files if missing.
• Validate Environment Variables: Ensures all required variables are correctly set.
• Format and Clean .env Files: Organizes and removes duplicate or incorrect entries.
