.env.go.local | !!exclusive!!

Your Go initialization code should handle this gracefully by logging a warning—not crashing—if .env.go.local is missing in production environments, allowing the application to read the system environment variables seamlessly. If you want to implement this in your project, let me know:

It used a popular library, godotenv . The logic was standard: it looked for a .env file. .env.go.local

But as your system grows—adding message queues, caching layers, dependent APIs, or multiple developers—one .env file often becomes a source of friction. Your Go initialization code should handle this gracefully

: This lightweight package is designed to look for files called env.json or .env in your project directory and apply them as environment variables, accessible via os.Getenv . It's based on a Node.js module, making it a good choice for teams with a polyglot background. But as your system grows—adding message queues, caching

The key insight here is that . When you call Load multiple times or pass multiple files, later files take precedence. This creates a clean hierarchy: system variables → .env → .env.local .
