javascript - Export function/class from node.js module -

i have class i've defined in javascript this:

var coolclass = function() {   this.prop1 = 'cool';   this.prop2 = 'neato'; }  coolclass.prototype.docoolthings = function(arg1, arg2) {   console.log(arg1 + ' pretty ' + this.prop1; }  modules.export = coolclass; 

i need able export can test in mocha using require. i'd still allow class instantiated in browser.

as of now, can load browser, instantiate , it's go. (obviously error in console not understanding keyword 'export' or 'module')

typically export multiple single functions using

exports.somefunction = function(args){}; 

but want export 1 function, none of methods i've added via prototype chain defined.

i've tried module.exports doesn't seem trick either. mocha spec requires file this:

var expect = require('chai').expect; var coolclass = require('../cool-class.js'); var mycoolclass;  beforeeach(function() {   mycoolclass = new coolclass();// looks here issue });  describe('coolclass', function() {   // if instantiate class here, works.   // methods added coolclass undefined  }); 

it looks beforeeach in mocha gets tripped up. can instantiate class in actual spec, , works fine.

on mochajs, need put beforeeach inside parent describe, , have specific scenarios on children describes. else, things done in beforeeach doesn't recognized describe. mycoolclass treated global variable , nothing instantiated, that's why prototype functions undefined.

so it's (sorry i'm on mobile):

var mycoolclass = require('mycoolclass.js'); describe('mymodule', function () {   var mycoolclass;    beforeeach(function () {     mycoolclass = new mycoolclass();   });    describe('my scenario 1', function () {     mycoolclass.dosomethingcool('this'); //or assert    }); }); 

you can @ documentation further details.
