To make this configurable and sharable, I'd suggest moving this into ``lib/config/index.js`` inside the ``addOverrides()`` function. After this line you could do:

    ...
    override(module.exports);
    module.exports.redisCli = redis.createClient(module.exports.redisConn);

Then all code could access it like this:

    var config = require('./config');
    ...
    config.redisCli.foo();
