javascript - How to use require in nodejs? -

-

मेरे पास 3 फ़ाइलें हैं:

बाल 1: 

  var parent = आवश्यकता होती है ('./parent'); माता-पिता ['प्रकार'] = 'बाल 1'; Module.exports = जनक;

चाइल्ड 2: 

  var माता = आवश्यक ('। / Parent'); माता-पिता ['प्रकार'] = 'बाल 2'; Module.exports = जनक;

अभिभावक: 

  module.exports = {'parent': 1}

test.js: < / P> 

  var test1 = आवश्यक ('। / Child1') var test2 = आवश्यकता है ('। / Child2')

परिणाम: 

  {माता-पिता: 1, प्रकार: 'बाल 2'} ---- {मूल: 1, प्रकार: 'बाल 2'}

क्यों?

से:

मॉड्यूल पहली बार लोड किए जाने के बाद कैश किए जाते हैं। इसका अर्थ है (अन्य बातों के अलावा) कि हर कॉल की आवश्यकता होती है ('फू') को उसी ऑब्जेक्ट को लौटा दिया जाएगा, अगर वह उसी फाइल को हल करेगा।

यह विशेष रूप से सुविधाजनक नहीं है केवल प्रदर्शन के लिए, लेकिन मॉड्यूल आरंभीकरण के लिए यदि आप विभिन्न ऑब्जेक्ट्स चाहते हैं, तो अपने मॉड्यूल को फ़ैक्टरी में बदलें।

I am trying to use the ASP.NET signal for the first time - here's what I did: created a new web Has been added to the project and the following signal R packages: I have created the following category: [Hub-name ("chat")] Public class ChatHub: Hub {Public Zero Halo () {Clients.All.hello ( ); }} and the following startup configuration: public partial class startup {public zero configuration (IAppBuilder app) {configure (app); App.MapSignalR (); }} However, whenever I navigate localhost: (port) / api / signalr / chat I get the following error: Protocol error: Unknown transport. I am running a new browser and trying different people so remove it from the API / URL, and just use the localhost: (potter) / signaller / Chat

Camel ProducerTemplate possible memory leak -

-
To some degree, this is a bit of a shot in the dark, but we have a process that is dramatically slow One day's course we have found that all the things running on the fuses begin to draw, but when we are running a specific process, JPPropellers are going on, I have found that the increase in magnetic usage increases over time. . Org.apache.camel.ProductTemplate.Send So my main question is, is the way in which the manufacturer product is being used here which is wrong / can this be a problem? exchange foo = new DefaultExchange (getCamelContext (), ExchangePattern.InOnly); Foo.getIn () setBody (obj). Root R = Exchange .getContext (). GetRoute ("do_something_fun"); Creator Template Template = exchange.getContext () CreateProducerTemplate (); Template.send (r.getEndpoint (), foo); Generally, you should not create a productive template on each request as described here: / P> However, because I do not have a complete picture of your application, so you can cr...

javascript - Adhering to a max length setting with jshint -

-
I get several recommendations to compile a maximum of 80 characters when writing javascript, e.g. Google, NPM, Node. JS, Crockford In some cases, though, I do not think how best to do this. MongoClient.connect ('mongodb: // localhost: 27017 / sampleDatabase', function (mistake, database) {if (err)} {throw error;} db = database;}); This will throw a jshint warning because it exceeds 80 characters. Now, do you choose to ignore the warning in this example, or instead choose an option for a solution like MongoClient.connect ('mongodb: // localhost: 27017 / sampleDatabase' , Function (err, database) {if (err) {throw error;} db = database;}); If you can reuse the url variable So, great option if this is a shot, as is often such a call, I would probably do something like this ... / * jslint sloppy: true, white: true, browser: True, maxlen: 80 * / / * global mongo client * / var dbarhh, db; DbErrHand = function (mistake, database) {if (err) {throw error; } ...
