Optional envOptional expandA boolean value indicating the use of expanded variables. If .env contains expanded variables, they'll only be parsed if this property is set to true.
Internally, dotenv-expand is used to expand variables.
Optional ignoreIf "true", environment files (.env) will be ignored.
Optional ignoreIf "true", predefined environment variables will not be validated.
Optional keyIf set, this function will transform all environment variable keys prior to parsing.
Be aware: If you transform multiple keys to the same value only one will remain!
environment variable key
.env file: `PORT=8080` and `keyTransformer: key => key.toLowerCase()` results in `{"port": 8080}`
Optional separatorIf set, use the separator to parse environment variables to objects.
app__port=8080
db__host=127.0.0.1
db__port=3000
if separator is set to __, environment variables above will be parsed as:
{
"app": {
"port": 8080
},
"db": {
"host": "127.0.0.1",
"port": 3000
}
}
