go-decouple

Package go-decouple is inspired by the python-decouple package. It provides a layer above godotenv that handles defaults and type conversion.

For example, if you want to read an integer value from an environment variable, you can call:

decouple.Load()
value, exists = decouple.GetInt("MY_INT_VAR", 0)

If MY_INT_VAR exists, value will be set to the integer value and exists will be true. If MY_INT_VAR does not exist, value will be set to 0 and exists will be false. If MY_INT_VAR exists but cannot be converted into the requested type, value will be set to 0 and exists will be false.
