Some people call this "dependency injection", I call it "passing arguments"

main.js

var connect = require('my-connector');
var dep1 = require('dep1');
var dep2 = require('dep2')

exports.default = function (config) {
  var connection = connect(config);
  var myDep1 = dep1.init(connection);
  var myDep2 = dep2.init(connection);
  
  return {
    doIt: function () {
      // Do interesting things with myDep1 and myDep2
    }
  };
}
