.env.go.local

Because .env.go.local is git-ignored, new developers won't know what variables your application requires to run. Create a .env.example file that is committed to Git. This file should contain all the necessary configuration keys but with dummy or empty values:

# API Keys EXTERNAL_API_KEY=your_external_api_key_here EXTERNAL_API_SECRET=your_external_api_secret_here .env.go.local

type Config struct Port int `env:"PORT" envDefault:"8080"` DBTimeout time.Duration `env:"DB_TIMEOUT" envDefault:"30s"` IsDebugMode bool `env:"DEBUG_MODE" envDefault:"false"` Because

Your codebase should be identical across different environments (local, staging, production). The only thing that changes is the configuration. .env.go.local keeps the local machine's setup separate from the team’s shared settings. 2. Enhanced Security The only thing that changes is the configuration

: A file used to override values specifically for local development. It is ignored by Git.

Go does not natively parse .env files out of the box; it reads directly from the host operating system's environment using the standard os package. To bridge this gap, Go developers rely on popular configuration libraries. The most robust tools for this are godotenv and viper . Method 1: Using ://github.com
