DefEnv

DefEnv is a go package that contains methods for extracting environment variables and converting them to specified types. If there is no environment variable, the default value is used.

There are two types of methods in a package: ordinary and strict. If there is no environment variable, or if a parsing error occurs, ordinary methods return a default value.

value := defenv.Int("WORKER_NUMBER", 8)

Unlike ordinary methods, strict methods return an error when parsing fails.

value, err := defenv.IntStrict("WORKER_NUMBER", 8)

Methods:

Type	Ordinary	Strict
bool	Bool	BoolStrict
time.Duration	Duration	DurationStrict
float64	Float64	Float64Strict
int	Int	IntStrict
int64	Int64	Int64Strict
string	String	-
uint	Uint	UintStrict
uint64	Uint64	Uint64Strict
