: This is a more advanced package. Its AutoLoad function is explicitly designed to load a default .env file, then automatically search for .env.local and .env.<GO_ENV>.local files. It effectively bakes this environment-aware loading pattern right into the library, reducing boilerplate code in your application.
import ( "log" "os" "github.com/joho/godotenv" )
In a typical Go application, you might have multiple environment variables that need to be set, such as database connections, API keys, or feature flags. These variables might be set in a variety of ways, including: .env.go.local
To implement a cascading override where .env.go.local takes precedence, you should use godotenv.Overload() .
Have you adopted the .env.go.local pattern in your team? Share your experience or alternative approaches in the comments below. : This is a more advanced package
He added a new ticket to the sprint board: "Remove env_loader.go and fire whoever thought godotenv.Overload was a good idea for production code."
// 3. Retrieve variables dbHost := os.Getenv("DB_HOST") dbPassword := os.Getenv("DB_PASSWORD") import ( "log" "os" "github
To tie everything together, here is a checklist of best practices you should adopt today.
If you need to load base environment variables but let local variables override them, use godotenv.Overload() .
// The ENV environment variable determines which additional files to load // If ENV is not set, it defaults to "dev"
