: Already set on the host machine (highest priority). .env.go.local : Machine-specific Go overrides (ignores Git). .env.local : General local overrides (ignores Git).
While Go's standard library provides os.Getenv and os.LookupEnv to retrieve environment variables, it does not natively parse .env files out of the box. To use files like .env.go.local , you will need a parser. Learn how to use .env files in Go projects
The number one rule of environment management is to never commit secrets (like database passwords, private API keys, or encryption salts) to Git. By putting your personal credentials into .env.go.local and adding it to your .gitignore , you eliminate the risk of accidentally pushing credentials to public or private repositories. 2. Team Flexibility ) Create a file named
# GitHub Actions example env: DATABASE_URL: $ secrets.DATABASE_URL API_KEY: $ secrets.API_KEY APP_PORT: 8080
Every developer has a unique local setup. One developer might run PostgreSQL natively on port 5432, while another runs it inside Docker on port 5433. Utilizing .env.go.local allows each team member to adjust variables to match their local machine without changing the shared .env file and causing Git conflicts. 3. Isolation in Monorepos
