env ignores lowerCase option

[OmgImAlexis]

I don't know if I'm missing something or not reading the docs correctly and I'm hoping someone here can help. Currently I'm using this setup in my app with a config.json file in the root of my repo. If the app uses docker instead of just launching it via the cli I would like to use redis inside of another container hence the need for ENV.

What I've noticed is that even when passing in DNS_PORT it's being added to the store with all capitals meaning when get() is called it finds the lowercase one even since there's now two DNS and dns fields in the store.

Maybe the lowerCase option should add the fields using lowerCase instead of just looking them up with lowerCase?

nconf.use('file', {
    file: path.join(__dirname, 'config.json')
}).defaults({
    redis: {
        host: "127.0.0.1",
        port: 6379
    },
    dns: {
        port: 5353
    }
}).env({
    separator: '_',
    lowerCase: true,
    whitelist: [
        'DNS_INTERFACE',
        'DNS_PORT',
        'DNS_ZONE',
        'REDIS_HOST',
        'REDIS_PORT',
        'LOGS_LEVEL'
    ]
});

The last line uses nconf.get('dns:port'); to set the server's port.
The output is from console.log(nconf.get());.

➜  redis-dns git:(master) ✗ export DNS_PORT=6000 && ./node_modules/.bin/babel-node index.js 
{ DNS: { PORT: '6000' },
  redis: { host: '127.0.0.1', port: 6379 },
  dns: { port: 2103, interface: '127.0.0.1', zone: 'redis-dns.local' },
  type: 'literal',
  logs: { level: 'warning' } }

did you find the issue? I'm having the same problem here

The issue is stated above. I ended up just switching to configstore.
