Particle.js + Node + Express - 无法获取要加载的资源(Particle.js + Node + Express - Can't get resource to load)

 乡亲。 这又是一个愚蠢的问题。 
 
 我正在研究使用particles.js作为背景，因为我学会了使用node和express。 在github上提供的文档中，它说使用： 
 
npm install particles.js
 
 做完这些之后，我添加了这个来在我的app.js中调用它： 
 
var particleJS = require("particle.js")
 
 然而，在这一点上，当我尝试运行我的应用程序时，节点错误状态如下： 
 
 ReferenceError：窗口未定义 
 
 还有另一个代码块应该被调用来创建这个应该在前端运行的代码块，使用一个jade文件。 
 
/* particlesJS.load(@dom-id, @path-json, @callback (optional)); */
particlesJS.load('particles-js', 'assets/particles.json', function() {
console.log('callback - particles.js config loaded');
});
 
 有几件事我不太确定。 首先，从我对节点的乐趣中，应该可以在app.js中调用npm install模块。 所以我觉得奇怪，它不起作用。这是因为有问题的代码不是基于像使用明确的框架？ 
 
 其次，如果是这种情况，我已经通过npm安装了particles.js模块，为了让玉器提取它，我必须将js复制到“javascript”公共目录中，以便它能够找到它？ 
 
 如果是这样的话，我不需要首先通过npm安装它？ 
 
 很多问题......对不起。 我仍然在学习，并用这个稍微运行一下。 也许我的逻辑在某个地方是错误的。 
 
 谁能帮忙？ 

folks. It's stupid question time again. 
 
I was looking into using particles.js as a background as i learned to use node and express. On the documentation available on the github, it says to use:
 
npm install particles.js
 
After doing this, i've added this to call it in my app.js:
 
var particleJS = require("particle.js")
 
At this point however, when i try to run my app, nodes error states:
 
ReferenceError: window is not defined
 
There is also another code block which is supposed to be called to create this which is supposed to be run on the frontend, using a jade file.
 
/* particlesJS.load(@dom-id, @path-json, @callback (optional)); */
particlesJS.load('particles-js', 'assets/particles.json', function() {
console.log('callback - particles.js config loaded');
});
 
There's a few things i'm not too sure about. Firstly, from my fun with node, npm install modules should be able to be called in the app.js. So i find it strange that it doesn't work.. Is this because the code in question isn't based around using a framework like express? 
 
Secondly, if this is the case and i've installed the particles.js module through npm, in order to have jade pick it up, i'd have to copy the js over to the "javascript" public directory so it can find it? 
 
And if thats the case i don't need to have it installed through npm in the first place?
 
So many questions... sorry. I'm still learning, and getting a little run around with this. Maybe my logic is wrong somewhere.
 
Can anyone help?
