I'm writing an SDK and I'd like to have a bunch of logs in there that can be turned on/off by the user of the SDK.

Currently I have this in my index.ts:

winston.configure({
  level: (process.env.DEBUG || process.env.VUE_APP_DEBUG) ? 'debug' : 'info',
  format: winston.format.combine(
    winston.format.json(),
    winston.format.prettyPrint(),
    winston.format.colorize({ all: true }),
  ),
  transports: [
    new winston.transports.Console(),
  ],
});

I was hoping that just by installing the package with npm and having a DEBUG or VUE_APP_DEBUG variable in the .env file of the user, the logger would turn on/off.

Alas this doesn't work:) What's the right way to do it?
