How to break static methods out to their own file and export correctly via ES6?

seems to work fine With an ES6 class, you can assign to the class object and have what is essentially a static method, just like what you'd do in ES5:
code :
class Door {
  constructor() {
    this.species = 'Oak';
    this.instanceMethod = fnInstanceMethod; // <-- works great
Door.create = fnCreate;
this.instanceMethod = fnInstanceMethod; // <-- works great
class Door {
  constructor() {
    this.species = 'Oak';
Door.create = fnCreate;
Door.prototype.instanceMethod = fnInstanceMethod;
// makeCreate.js
module.exports = theClass => () => new theClass();

// Door.js
const makeCreate = require('./makeCreate');
const fnInstanceMethod = require('./instanceMethod');
class Door {
  constructor() {
    this.species = 'Oak';
Door.create = makeCreate(Door);
Door.prototype.instanceMethod = fnInstanceMethod;

module.exports = Door;
function makeCreate(theClass) {
  return function() {
    return new theClass();
module.exports = makeCreate;

Closure compiler export all prototypes & static methods

hope this fix your issue What you describe is really what externs is for: Prevent Google Closure Compiler from renaming settings objects
You can see an example of a large externs file here: http://code.google.com/p/closure-compiler/source/browse/trunk/contrib/externs/jquery-1.6.js
code :
jQuery.prototype.add = function(arg1, context) {};

ES6 modules: Export single class of static methods OR multiple individual methods

will help you
A class of just static methods feels like a bit of a 'code smell'
code :
//------ myMethods.js ------

export default {
  myMethod1() {
  myMethod2(args...) {

How to correctly use static variables in class methods?

I wish this helpful for you To assign values to static variables which are the result of expressions will cause a parse error.
code :
static $int = 0;          // correct 
static $int = 1+2;        // wrong  (as it is an expression)
static $int = sqrt(121);  // wrong  (as it is an expression too)

NodeJS export class with static methods

Does that help That is the correct approach although in your example you could simply store the values as primitives: Config.SVR_PORT = 8080, note I rewrote those as "constants", since I don't recommend changing statics.
When this is said, then please note: Do not put any sensitive data (passwords, etc) in your JavaScript files, but instead put these in a config file. This will separate config from code. And help you not to leak any potential critical information.
