I am writing a simple MEAN app, and I am currently working on the routes.
In my server.js, I have
var express = require('express');
var multer = require('multer');
var upload = multer({dest: 'uploads/'});
var sizeOf = require('image-size');
var app = express();
var mongoose = require('mongoose');
var bodyParser = require('body-parser');
var methodOverride = require('method-override');
// configuration ===========================================
require('./app/models/Purchase');
require('./app/models/Seller');
require('./app/models/User');
// config files
var db = require('./config/db');
var port = process.env.PORT || 8080; // set our port
// mongoose.connect(db.url); // connect to our mongoDB database
// get all data/stuff of the body (POST) parameters
app.use(bodyParser.json()); // parse application/json
app.use(bodyParser.json({ type: 'application/vnd.api+json' })); // parse application/vnd.api+json as json
app.use(bodyParser.urlencoded({ extended: true })); // parse application/x-www-form-urlencoded
app.use(methodOverride('X-HTTP-Method-Override')); // override with the X-HTTP-Method-Override header in the request. simulate DELETE/PUT
app.use(express.static(__dirname + '/public')); // set the static files location /public/img will be /img for users
// routes ==================================================
var routes = require('./app/routes/routes');//(app); // pass our application into our routes
var price = require('./app/routes/pricing');
var processing = require('./app/routes/processing');
var uploads = require('./app/routes/uploads');
var seller = require('./app/routes/seller');
app.use('/', routes);
app.use('/price', price);
app.use('/processing', processing);
app.use('/uploads', uploads);
app.use('/seller', seller);
// start app ===============================================
app.listen(port);
console.log('Magic happens on port ' + port);
exports = module.exports = app;
Then, in my route, I have
var express = require('express');
var mongoose = require('mongoose');
var Seller = mongoose.model('Seller');
var router = express.Router();
router.get('/', function(req,res){
res.json({message: 'youre in router.get'});
});
router.post('/registerSeller', function(req,res,next){
console.log('You made it all the way to seller route!');
res.json({message: "you did it"});
next();
});
module.exports = router;
When I start my node server, everything goes well. When I use Postman to POST to the above route, it just 'hangs' and eventually gives an error message that it cannot connect. In Postman, I select 'POST' to http://localhost:8080/seller/registerSeller.Clicking 'code', I get
POST /seller/registerSeller HTTP/1.1
Host: localhost:8080
Cache-Control: no-cache
Postman-Token: 070cb9b3-992a-ffd6-cede-c5b609bc9ce5
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
Looking at the browser's developer tools, it shows a POST being made, and then after a while, it also reads that the POST failed.
Could anyone tell me what I'm doing wrong? Thank you.
The problem is that you are responding and then trying to call the next() function in the router stack.
router.post('/registerSeller', function(req,res,next){
console.log('You made it all the way to seller route!');
return res.send({message: "you did it"});
//next(); remove this shit.
});
This should work. Express middlewares go in order. So if you need to have a middleware to be called before this function, then you have to put it before in the stack. If you need to do something after this function, forget about the res.json... part.

I'll try to make this as to the point as possible. I am trying to make a post request to my express backend. All of the post requests here work, except for "/addpayment". Here is my file called 'router.js'
module.exports = function(app) {
app.post('/signin', requireSignin, Authentication.signin)
app.post('/signup', Authentication.signup)
app.post('/addpayment', function(req, res, next) {
res.send({ message: 'why................' })
})
}
Here is my main 'server.js' file
const express = require('express')
const http = require('http')
const bodyParser = require('body-parser')
const morgan = require('morgan')
const app = express()
const router = require('./router')
const mongoose = require('mongoose')
const cors = require('cors')
// DB Connect
mongoose.connect('mongodb://localhost/demo-app')
// App
app.use(morgan('combined'))
app.use(cors())
app.use(bodyParser.json({ type: '*/*' }))
router(app)
// Server
const port = process.env.PORT || 3090
const server = http.createServer(app)
server.listen(port)
console.log('Server has been started, and is listening on port: ' + port)
I get a 404 in postman, and inside my app browser console. I am using passport in my other routes. I already tried running it through passport when I have a JWT token, and same thing(a 404).
I have already looked at all Stack Overflow/Github posts on the first few pages of google results, with no solution for my use case.
I have made a simplified version of your server and everything works as expected. Only difference that I have made is that I am not creating http server like you, but just calling app.listen
here is working example
router.js
module.exports = function(app) {
app.post('/addpayment', function(req, res, next) {
res.send({message: 'why................'})
})
};
server.js
var express = require('express');
var router = require('./router');
var app = express();
router(app);
//init server
app.listen(3000, function() {
console.log("Server running on port 3000");
});
I'm currently writing a web application with the MEAN stack, and am testing to see if my nodejs server is working. Here's my server.js:
// server.js
'use strict';
// modules =================================================
const path = require('path');
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const methodOverride = require('method-override');
// configuration ===========================================
// config files
const db = require('./config/db');
// set our port
var port = process.env.PORT || 8080;
// connect to mongoDB
// (uncomment after entering in credentials in config file)
// mongoose.connect(db.url);
// get all data/stuff of the body (POST) parameters
// parse application/json
app.use(bodyParser.json());
// parse application/vnd.api+json as json
app.use(bodyParser.json({ type: 'application/vnd.api+json' }));
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: true }));
// override with the X-HTTP-Method-Override header in the request simulate DELETE/PUT
app.use(methodOverride('X-HTTP-Method-Override'));
// set the static files location /public/img will be /img for users
app.use(express.static(__dirname + '/public'));
// routes ==================================================
require('./app/routes')(app); // configure our routes
// start app ===============================================
// startup our app at http://localhost:8080
app.listen(port);
// shoutout to the user
console.log('App running on port ' + port);
// expose app
exports = module.exports = app;
I currently have it redirecting all routes to my index.html file to test to make sure my views are working. Here's my routes.js:
// models/routes.js
// grab the user model
var User = require('./models/user.js');
module.exports = {
// TODO: Add all routes needed by application
// frontend routes =========================================================
// route to handle all angular requests
app.get('*', function(req, res) {
res.sendfile('./public/index.html'); // load our public/index.html file
});
};
However, when I try to run node server.js, it gives me this error:
/home/hess/Projects/FitTrak/app/routes.js
app.get('*', function(req, res) {
^
SyntaxError: Unexpected token .
Does anyone have any idea what's causing this? I checked and all my braces and parentheses are all closed and written correctly.
As Jose Hermosilla Rodrigo said in his comment, you're declaring the object literal module.exports wrong. It should look like this instead:
module.exports = function(app) {
app.get('*', function(req, res) {
res.sendfile('./public/index.html'); // load our public/index.html file
});
};
just try this code...
// models/routes.js
var express=require('express');
var app=express();
// TODO: Add all routes needed by application
// frontend routes =========================================================
// route to handle all angular requests
app.get('*', function(req, res) {
res.sendfile('./public/index.html');
});
module.exports = route;
server.js
'use strict';
const path = require('path');
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
var route=require('./models/route.js');
const methodOverride = require('method-override');
// configuration ===========================================
// config files
const db = require('./config/db');
// set our port
var port = process.env.PORT || 8080;
// connect to mongoDB
// (uncomment after entering in credentials in config file)
// mongoose.connect(db.url);
// get all data/stuff of the body (POST) parameters
// parse application/json
app.use(bodyParser.json());
// parse application/vnd.api+json as json
app.use(bodyParser.json({ type: 'application/vnd.api+json' }));
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: true }));
// override with the X-HTTP-Method-Override header in the request simulate DELETE/PUT
app.use(methodOverride('X-HTTP-Method-Override'));
// set the static files location /public/img will be /img for users
app.use(express.static(__dirname + '/public'));
// routes ==================================================
require('./app/routes')(app); // configure our routes
// start app ===============================================
// startup our app at http://localhost:8080
app.listen(port);
// shoutout to the user
console.log('App running on port ' + port);
app.use('/',route);
If you are using MEAN stack I would suggest you to use express own router middleware to handle all your routes. Just include.
var router = express.Router();
//use router to handle all your request
router.get(/xxx,function(req, res){
res.send(/xxxx);
})
// You may have n number of router for all your request
//And at last all you have to do is export router
module.exports = router;
I'm having a small problem when building a CRUD Api with node.js and express.
When I post to my API I get "ReferenceError: Phone is not defined"
// server.js
// BASE SETUP
// =============================================================================
// call the packages we need
var express = require('express'); // call express
var app = express(); // define our app using express
var bodyParser = require('body-parser');
var phone = require('./models/phone');
var mongoose = require('mongoose');
mongoose.connect('mongodb://<userID>:<pass>#apollo.modulusmongo.net:27017/ugygY5qe');
// configure app to use bodyParser()
// this will let us get the data from a POST
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
var port = process.env.PORT || 8080; // set our port
// ROUTES FOR OUR API
// =============================================================================
var router = express.Router(); // get an instance of the express Router
router.use(function(req,res,next){
console.log('Something is happening');
next();
});
router.route('/phones').post(function(req, res){
var phone = new Phone();
phone.name = req.body.name;
phone.save(function(err){
if(err){
res.send(err);
}
res.json({message: 'Phone Create'});
});
});
// test route to make sure everything is working (accessed at GET http://localhost:8080/api)
router.get('/', function(req, res) {
res.json({ message: 'hooray! welcome to our api!' });
});
// more routes for our API will happen here
// REGISTER OUR ROUTES -------------------------------
// all of our routes will be prefixed with /api
app.use('/api', router);
// START THE SERVER
// =============================================================================
app.listen(port);
console.log('Magic happens on port ' + port);
And here is my schema file.
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var phoneSchema = new Schema({
name: String
});
module.exports = mongoose.model('Phone', phoneSchema);
I'm not sure where the error is. I've consulted the mongoose docs, search around but still can't get anything to work.
Just a typo ! check line no 4.
var Phone = require('./models/phone');
I'm trying to verify a signed token and extract information from it using NodeJS.
I have a token named userToken in the browser right now, it has been saved after I logged in (I use auth0 to login by the way).
I tried to verify my token here manually : http://jwt.io , it works and gives me payload data without a problem. However, I can't do the same thing with NodeJS. How can I do it?
I read the docs but I couldn't get it.
https://github.com/auth0/express-jwt
Here's my server.js
var http = require('http');
var express = require('express');
var cors = require('cors');
var app = express();
var jwt = require('express-jwt');
var dotenv = require('dotenv');
dotenv.load();
var authenticate = jwt({
secret: new Buffer(process.env.AUTH0_CLIENT_SECRET, 'base64'),
audience: process.env.AUTH0_CLIENT_ID
});
// view engine setup
var path = require('path');
app.set('views', path.join(__dirname, 'views'));
app.use(express.static(path.join(__dirname, 'public')));
app.set('view engine', 'jade');
app.configure(function () {
// Request body parsing middleware should be above methodOverride
app.use(express.bodyParser());
app.use(express.urlencoded());
app.use(express.json());
app.use(cors());
app.use(app.router);
});
app.get('/', function (req, res) {
res.render('index');
});
app.get('/test', function(req,res) {
// how do I check it?
});
var port = process.env.PORT || 3001;
http.createServer(app).listen(port, function (err) {
console.log('listening in http://localhost:' + port);
});
You dont't need to implement nothing. Since you are using this express-jwt, just pass the userProperty tag to jwt:
var authenticate = jwt({
secret: new Buffer(process.env.AUTH0_CLIENT_SECRET, 'base64'),
audience: process.env.AUTH0_CLIENT_ID,
userProperty: 'payload'
});
So, you can get all of your jwt payload data using req.payload in your controllers. You can check it with console.log(req.payload).
You can see how it works here: https://github.com/auth0/express-jwt/blob/master/lib/index.js#L121
I hope it helps, and sorry about my English.
This sample should help you, it's not tested, but sure it's right way, look at source of express-jwt, it does literally same behind the scenes
app.get('/test', function(req, res) {
var jsonwebtoken = require('jsonwebtoken'); //install this, move to declarations
var loginToken = req.headers.authentication || req.body.userToken || req.headers.Bearer; //or your own, it's just headers that pass from browser to client
jsonwebtoken.verify(loginToken, new Buffer(process.env.AUTH0_CLIENT_SECRET, 'base64'), function(err, decoded) {
if(err) {
return res.status(401).send({message: 'invalid_token'});
}
//be aware of encoded data structure, simply console.log(decoded); to see what it contains
res.send(decoded); //`decoded.foo` has your value
});
});
The thing is that you must yourself encode your data, and then decode, so be aware that auth0 returns valid data structure for you (as i'm not sure otherwise)
I'm working through a basic node tutorial and am having difficulty getting my routes.js file to work.
It was working earlier today. The server Node is reading the file. For some reason, though it is not utilizing it. My code looks exactly like the tutorial -- though the teacher is on a PC and I am on a Mac (though I can't see why that would matter).
Before this issue started to occur, I hooked up my database (file below) -- but again, I can't see why that would screw with my routes. When I put this code in server.js, I can get the proper routing.
Help me stackoverflow, you're my only hope! All I see is "Cannot GET /"
My routes.js file
var User = require('../models/user');
module.exports = function(app){
app.get('/', function(req, res){
res.send("Hello World");
});
// app.get('/:username/:password', function(req, res){
// var newUser = new User();
// newUser.local.username = req.params.username;
// newUser.local.password = req.params.password;
// console.log(newUser.local.username + " " + newUser.local.password);
// newUser.save(function(err){
// if(err)
// throw err;
// });
// res.send('Success!')
// });
};
server.js
var express = require('express');
var app = express();
var port = process.env.PORT || 8080;
var cookieParser = require('cookie-parser');
var session = require('express-session');
var morgan = require('morgan');
var mongoose = require('mongoose');
//Config Database
var configDB = require('./config/database.js');
mongoose.connect(configDB.url);
//MIDDLEWARE is run during every interaction;
app.use(morgan('dev'));
//sets req.cookies
app.use(cookieParser());
app.use(session({
//secret for user session
secret: "ist0",
//if the server goes down, the user can remain logged on -- still save to database
saveUninitialized: true,
//even if nothing has changed, resave
resave: true
}));
//ROUTES
require('./app/routes/routes');
// app.use('/', function(req, res){
// //send is express function
// res.send("Our first express program");
// console.log(req.cookies);
// console.log("============");
// console.log(req.session);
// });
app.listen(port);
console.log('The magic happens on ' + port)
My database.js file:
module.exports = {
'url': 'mongodb://localhost/meanboil'
}
You are exporting a function (one that expects app as an argument):
module.exports = function(app) { ... }
But you're just importing that function and don't actually call it:
require('./app/routes/routes');
Instead, you need to call it and pass app as argument:
require('./app/routes/routes')(app);
