问题 I have a to access the config variables defined in the file called test.js which has -- var aws = require('aws-sdk'); exports.connect = function(){ return aws; } Now I need to access it when the OnClick event occurs on the browser.

问题 I'm using node + express as my web server, and has a cluster of 4 workers . I tried several ways to deliberately kill a worker : process.exit() in a controller, and triggered using a browser action. Thought this is just for a single worker process, but turned out all workers were killed. Again in a controller, I let a worker send suicide announcement to the master : process.send('suicide'); and here goes my master process: if (cluster.isMaster) { console.log(`Master cluster setting up $

问题 So I have been working on a SPA project using Sailsjs . The problem is: When the first page loads, I use res.view or res.render in my controller. But, for subsequent requests, I dont want to use res.view or res.render , rather I'd like to use res.json . Right now, I use the method: return req.param('json') ? res.json(myObj) : res.view('layout', myObj); This works, but I was looking for a more generic and abstract method in which my controller itself would know (on the basis of req.param('json

问题 I'm following a tutorial in which I created a simple "Hello World" in Express. The tutorial gets everything up and running locally just fine with 'npm start'. The tutorial then moves on to prepare for uploading code to Heroku via Toolbelt. Following the directions (so far as I can tell), I execute 'foreman start'. When I hit the localhost URI, I get the basic HTML I'm expecting, but no CSS (no doubt related to the ERR_CONNECTION_REFUSED outputs I see in the console window, which is probably

问题 After reading many similar threads, I failed to see the reason of my problem... Im trying to learn how to create a RESTful API with node and express 4, pretty basic and simple, but when i try to save my document with a POST req, no req.body is sent on the request and i have some problems. Lets look a little piece of code: module.exports = (router, Bear) -> router.route '/bears' .get (req, res) -> Bear.find (err, bears) -> if err then err else res.json bears .post (req, res) -> newBear = _id:

问题 I have been working on porting a basic Express based app to Meteor. The excellent post Is there an easy way to convert an express app to meteor? was a great start, using a waiter function to wrap iron-router routes that Meteor expects into req / res that Express likes. However, I've hit a bug that I'm stuck on. I'm not able to get Meteor to pass the res.render object over to my handlebars templating engine. For example: main.js app.get('/complex', function(req, res){ var data = { name:
