How to handle one express route different than all other
javascript,node.js,express,routes
As of Express version 4.x, app.router has been removed. Routes are now executed in the order they are added. Now you may use the express.Router because it will allow you to have isolated instances of routes and in your example you could create many routers with their own versioned routes....
Express Router Prefix
You can write your route files like so: module.exports = function (app) { 'use strict'; var router = express.Router(); router.get('/', getAllExercises); router.get('/:id', getExerciseById); app.use('/api/exercises', router); }; And require each of them like this: require('./routes/exercises')(app); Note that you can replace __dirname + '/... with './.......
Express - preventing two+ responses from being sent
You can check for res.headersSent if (res.headersSent) return; client.info(function (err, resp) { //this callback will also invoke res.send if (res.headersSent) return; response['redisInfo'] = resp; res.status(200).send({"test message from SmartConnect": response}); }); ...
ExpressJs is not serving index.html
So after many hours of fiddling and reading I replaced this code: app.use(express.static('./src/app')); app.use(express.static('./')); app.use(express.static('./temp')); app.use('/*', express.static('./src/index.html')); with this: app.use(express.static(__dirname)); app.use(express.static(process.cwd())); app.route('/*') .get(function(req, res) { res.sendFile(__dirname + '/index.html'); }); and it appears to have solved the problem...
Send a POST when the user hits the bottom?
"what is doing the 'posting'" When a Form gets submitted, it's that which does the 'POSTing'. A "submit" is an action, like a function call, not simply a boolean value being watched for true or false. <form method="POST" action="/url"> <input name="name" value="value"> <button>Submit</button> </form> Here when the button will...
Error handling when uploading file using multer with expressjs
You can handle errors using the onError option: app.post('/upload',[ multer({ dest : './uploads/', onError : function(err, next) { console.log('error', err); next(err); } }), function(req, res) { res.status(204).end(); } ]); If you call next(err), your route handler (generating the 204) will be skipped and the error will be handled by Express....
Select Mongoose Model Based on Express Route
You can get models by name: var mongoose = require('mongoose'); app.get('/:trial', function(req, res){ var trial = req.params.trial; mongoose.Model(trial).find(function(err, records) { if (err) { // Return when we end the response here... return res.send(err); } res.json(records); // returns all trial records in JSON format }); }); Depending on circumstances, I would...
How to correctly use Express 4 multiple routers
javascript,node.js,express,routes
Method routes (.get, .post, and of course .all) are terminal. This is why you can use wildcards with them as well. .use is not terminal and doesn't allow wildcards -- it acts as a prefix. This is an implementation choice of express. Use .use without wildcards. .use does not set...
Express js 4, Parse.com JSON error
javascript,jquery,node.js,express,parse.com
There's a typo in your express code. You're referencing req.data when it should be req.body.data: For instance, this: var user = new Parse.User(); user.set("username", req.data.email); user.set("password", req.data.pw); user.set("email", req.data.email); Should be this: var user = new Parse.User(); user.set("username", req.body.data.email); user.set("password", req.body.data.pw); user.set("email", req.body.data.email); Also, your initial data array is actually...
NodeJs + ExpressJs app routing odd behavior
angularjs,node.js,express,mongoose,passport.js
So apparently the problem is that HTML defaults to finding an index.html file in any folder within the root. When I change the html file to something else like abc.html the problem is solved. Seems like a bug to me.
What is wrong with Nodejs?
node.js,express,runtime-error,middleware,multer
What done=true is doing, is declaring a global variable called done. In order for it to not be a global variable, use the var key word e.g. var done = true. It is generally regarded as a bad idea to declare global variables. JavaScript has an optional mode called strict...
Not able to access result returned from mongoDb outside query
The callback from toArray is asynchronous, i.e. will happen after your console.log line executes, therefore you need to re-arrange as follows: var collectionOne = []; router.get('/fetch',function(req, res, next){ MongoClient.connect('mongodb://localhost:27017/local', function(err, db){ var collection = db.collection('borrower'); db.collection("borrower", function(err, collection) { collection.find().toArray(function(err, result) { if (err) { throw err; } else {...
Dropzone.js status is pending and not uploading a file
javascript,node.js,backbone.js,express,dropzone.js
I solved the issue by enabling Cache-Control in Access-Control-Allow-Header header of my Node server. app.use(function (req, res, next) { res.header('Access-Control-Allow-Origin', '*'); res.header('Access-Control-Allow-Headers', 'Cache-Control, Origin, X-Requested-With, Content-Type, Accept, Authorization'); res.header('Access-Control-Allow-Methods', 'GET,PUT,PATCH,POST,DELETE'); if (req.method === 'OPTIONS') return res.end(); next(); }); ...

How to include parameters in url using nodejs+jade?
It depends on whether you will make your app to be RESTful or not. Saying you would like to be Restful. To create an admin you should make a POST to the url /admin. Respectively to create an account you should post to the url /account. This is if admin...
How to use passport.js's TwitterStrategy sessionless?
From Passport twitter middleware issue reported earlier on gihub Any OAuth 1.0 strategy requires sessions. OAuth 2 requires it if state is enabled (which is highly recommended). A temporary secret is stored in the session to prevent cross site scripting attacks. ...
Using middleware to call an Authentication API using ExpressJS
angularjs,node.js,authentication,express
It looks like the middleware is being fired from the OPTIONS request. Using a more robust express library like cors will solve this problem. Alternatively, you could check for the OPTIONS request manually, then return the necessary information instead of calling next(), but unless you know exactly what you're doing,...
pretty print json directly in page from Express
Depending on what you're going for using browser extensions or a program like Postman will make it easier for you to develop against.
Express can't set headers after they're sent while downloading from mobile
When a browser asks the server for a request with a GET, it sends an ACCEPT statement in the header information. See https://developer.mozilla.org/en-US/docs/Web/HTTP/Content_negotiation#The_Accept.3A_header So, I'd guess that your browser makes its request and says to the server (in its header) "I can accept graphics files, video files, HTML files, text...
Write NodeJS stream into a string synchronously
Streams in node.js are not synchronous - they are event driven. They just aren't synchronous. So, you can't get their results into a string synchronously. If you have no choice but to use a stream, then you have no choice but to deal with the contents of the stream asynchronously....
Is it possible to send data directly to a constructor?
Express doesn't really care about constructors or objects. You can certainly use them, but then you need to do some plumbing to use them within a middleware function. Instead, you might want to think in terms of middleware functions. A common pattern in node development is to define one (or...
Set multer properties inside an express route
Multer is it's own middleware. You can add it to a route via: router.post('/uploads', multer({ dest: './my/destination' //req.app.get('cfg').uploads.dir }), function (req, res, next) { console.log(req.files); process.exit(); }); Though you're going to have to find another way to access your config. One way would be to pass the config or app...
How to get ip in socket io

zip and download from nodejs
Try zip2.writeToResponse(res,'folder.zip'); instead of zip2.writeToFile('folder.zip');
Adding attributes for fields using ejs view helpers
You are probably looking for text_field_tag, because type="5" doesn't make much sense. You can pass object as third argument to text_field_tag with attributes you want to set. <%- text_field_tag('inputFld', '5', {id: 'inputFldId', Class: 'some_class'}) %> ...
How to validate presence of parameter in API call
The problem is that your middleware will only be called on routes that include the :id param, because you have it mounted on '/players/:id/info'. You'll need to mount it on '/players' in order to match both cases.
Why method passed as argument wont work here
Could be that the execution context is different. When you say res.redirect(redirectUrl), this inside the redirect method is referring to the res object(unless a custom execution context is used), but when you pass res.redirect as a callback, when the callback is invoked the context is lost. router.get('/auth',function(req, res, next){ auth.beginOauth(res.redirect.bind(res));...
Class atributes not updating [node.js - express ]
javascript,node.js,class,express,neo4j
.save is asynchronous, so you can't use the value returned by it outside its callback, hence moving the rest of your code inside the callback will fix it: var t = this; this.db.save(vals, function (err, node) { if (err) throw err; vals = node; console.log("2:"); // output print console.log(vals); //...
NodeJS for a JAVA developer - Few Questions
1) Node is using Javascript so it is single threaded and non-blocking. 2) If i understand correctly what you mean.. yes you can have a single file application. Which probably make your life miserable when the app grows big. 3) Yes.This variable will be accessible through out the file. For...
NodeJS / ExpressJS check valid token parameter before routing

Get local json file using request-promise
javascript,json,angularjs,node.js,express
Relative paths (starting with ../ or ./) are relative to the current working directory. If you want to read a file relative to the current JS source file, you need to prefix the path with __dirname, which is the directory where the current JS source file resides: fs.readFile(__dirname + '/../testJSON/user.json',...
Csurf invalid csrf token Express / nodejs
node.js,cookies,express,csrf,mean-stack

How to redirect and then stop in node.js
javascript,node.js,redirect,express
You should use middleware. Here's an example: // you can include this function elsewhere; just make sure you have access to it var blockIfLoggedIn = function (req, res, next) { if (req.isAuthenticated()) { req.flash('error', 'Sorry, but you cannot access this page.') return res.redirect('/') } else { return next() } }...

http.createServer(function(req, res) { res.end("Request received on 9001"); }).listen(9056); Your HTTP server is listening on port 9056. The proxy tries to connect to a HTTP server on wrong port and throws an error, when connection cannot be established. To avoid errors like this on the future, put port in a variable:...
How to handle expressjs middleware request. post request remains pending made by dropzone
node.js,express,dropzone.js,multer
You need an Express route for your form post that will finish the http request. The multer middleware will process the file uploads and add them to the request so they are available to a route handler, but you need to have a route for the form post. From the...
Node forward path request to another server
node.js,express,routing,routes,request
This works: here's what you need to put in your node app: var express = require('express'); var app = module.exports = express(); var proxy = require('http-proxy').createProxyServer({ host: 'http://your_blog.com', // port: 80 }); app.use('/blog', function(req, res, next) { proxy.web(req, res, { target: 'http://your_blog.com' }, next); }); app.listen(80, function(){ console.log('Listening!'); }); Then...
Redis: Delete user token by email ( find Key by Value )
You basically have to choose one of two approaches: a full scan of the database or an index. A full scan, as proposed in another answer to this question, will be quite inefficient - you'll go over your entire keyspace (or at least all the tokens) and will need to...
Jade / Expressjs: Pass objects from server to client
javascript,node.js,express,jade
If you want to interpolate object from you express, the easiest and cleanest way is to serialize them. For the moment, once interpolated, you are trying to write something like this: var stats = [Object object]; Which isn't a valid JavaScript syntax :/ So, on the server side, serialize your...

Use socket.io-client with Express and nodejs to send query to java server
The structure of your controller is a bit messed up. Here are some things that are wrong: You connect to the Java server when the module is loaded, but you don't assign a connect event handler until the route gets hit. This means you will normally miss the connect event...
Req.files in undefined at the server side (built with express & node) when sending files using dropzone
The tutorial you were following is quite outdated, and certainly written for old version of express. With express 4.0, released in April 2014, (almost) all built-in middleware was dropped, including the one parsing uploaded files as req.files. That's the problem, and the solution is to use separate module to handle...
Where should I put routes in express.js
This is completely preferential. Any pattern that works is likely to be valid here. Express routers make things very nice and easy to setup. Personally I prefer to create a directory for every top level route, files for the second level, and exports for the third. Here's an example of...
Passing data from server/app.js to controller Angular-fullstack + multer
javascript,angularjs,node.js,express,multer
OK so after battling with this all day i've got a dirty fix that works so i thought i'd share it with you, but there really must be a cleaner, more elegant way of doing this: app.post('/api/photo',function(req,res){ if(done==true){ photoName = req.files.userPhoto.name; photoName = encodeURIComponent(photoName); res.redirect('../course?img=' + photoName); } }); Just...
Express.js server with Apache Tomcat
I don't believe that combining express.js (simple web server for Node.JS platform) and Apache Tomcat (Servlet container from JVM world) make sense at all. I bet that you are confusing Apache Web Server with Apache Tomcat. They are two completely separate projects. If that is the case than notice that...

What is the best framework and difference of nodejs framework
They are not very comparable. If you want to create a real-time application, you will probably need to use both. Express is a web framework.

Emitting and receiving socket io within the same file
If you are trying to emit and listen for events within the same file, you should be using the built in event listeners for node, not the specialized ones for socket.io (https://nodejs.org/api/events.html): var EventEmitter = require('events').EventEmitter; var eventExample = new EventEmitter; //You can create event listeners: eventExample.on('anEvent', function(someData){ //Do something...
Include whole directory of scripts using Jade?
javascript,node.js,express,jade
There is no possibility to use such wildcards in Jade, it has no such notion of your filesystem. You can create a mixin that will help a bit though, for example: mixin scripts(path, names) - each name in names script(type="text/javascript", src=path+name+".js") +scripts("/vendor/", ["angular", "angular-resource", "angular-route"]) For the possibility of automatical...

Node Server - Source Code accessible
The obvious answer is to change the directory used in the express.static() middleware if you're using that. Typically there is a public or similarly-named directory that you would create that holds only your public assets.

Express is for backend servers.

Using Express' route paths to match `/` and `/index`
javascript,regex,node.js,express,path
The question mark is for optional route parameters, not optional route segments. For example: app.route('/:myVar?'); With app.route('/(index)?'); you are matching routes that are literally "http://myapp.com/(index)". You want a regular expression route. app.route(/^\/(index)?$/); ^ - matches the beginning of a line, so that the whole expression must match from the beginning....

Socket.io client does not connect to server
I don't know if this is the only issue, but you're calling this: var io = require("socket.io").listen(app); before you assign the app variable so it is undefined. The request for this URL: http://localhost:3000/socket.io/?EIO=3&transport=polling&t=1434334401655-37 is how a socket.io connection starts so that is normal. The problem is that the socket.io listener...

how to determine logged in user in a mean stack application
node.js,express,mean-stack,meanjs
If you are using passport you just have to access req.user as it was already mentioned. Taking a look at your gist, my guess is that some of your routes are defined much earlier than app.use(passport.initialize()); and app.use(passport.session());, which means that if you receive a request to get /opportunity_ids (for...
Angularjs Login authentication redirection getting — Error: Can't set headers after they are sent
