Envhanced-Config

Environment variables are universal and simple way to pass configuration parameters to an application. However, they are not well suited for more complex configurations for which a structured config file is more suited.

Enhanced-Config allows you to combine both approaches by allowing Environment variables in JSON files.

Example Envhanced Config File

{
    "transport": {
        "net": {
            "port": ${PORT:80},
            "hostname": "${HOSTNAME:localhost}",
            "password": ${str(PASSWORD)}
        }
    }
}

Parsing a file

import envhanced from "./envhanced.ts";
const parsed = envhanced(config);
