I have the following file: (auth.js)
module.exports = function (express, mongoose, router) {
router.route('/setup')
.get(function (req, res) {
var salt = bcrypt.genSaltSync(10);
var hashed = bcrypt.hashSync(req.query.password, salt);
// create a sample user
mongoose.models.playlist.create({username: 'Hieratic', password: hashed}, function (err, item) {
if (err) throw err;
console.log('User saved successfully');
res.json({ success: true });
});
});
return router;
};
And the current server file: (server.js)
"use strict";
var url = require('url');
var express = require('express');
var bodyParser = require('body-parser');
var fs = require('fs');
var crypto = require('crypto');
//npm install request

}
process.on('disconnect', function () {

mongoose.disconnect();
});
require('./auth.js')(express, mongoose, router);
var port = 51000;
app.listen(port);
console.log('Magic happens at http://localhost:' + port);
When i attempt to access the /setup route it does hit the server however it throws an html page:
(http://localhost:51000/setup):
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Cannot GET /setup</pre>
</body>
Can anyone see what ive done wrong?
You have created router, but not registered it as a middleware:
var router = express.Router();
require('./auth.js')(express, mongoose, router);
app.use(router);
Refer to Cannot GET / Nodejs Error
You have no route set up.
Serve your page like this:
app.get('/', function (req, res) {
res.render('index', {});
});

I am new with connecting client and server side, and it might be why I couldn't find an answer for my question. Is a simple question.
As you can see I want to send "hey" from the client to the server(user.js). However I don't know how does I catch the response on the server side.
I know that a "hey" or neither the code make much sense, but is just an example to make things simple, I just wondering how does the server side could catch and handle the data.
Thanks in advance!
When you post data, specify how you are encoding it. It's generally best to use a standard encoding method rather than POSTing plain text. (Also don't start variable names with capital letters unless they are constructor functions)
const http = new XMLHttpRequest();
const url = 'http://localhost:4550/users';
const data = JSON.stringify({ value: "hey" });
http.open("POST", url);
http.setRequestHeader("Content-Type", "application/json");
http.send(data);
http.onreadystatechange = (e) => {
console.log(http.responseText)
}
Then in your server side code, use a body parser to decode the data.
Since you are using an absolute URL in the request, it seems likely that you are making a cross-origin request so you also need to grant permission using CORS.
const express = require('express')
const bodyParser = require('body-parser')
const cors = require('cors')
const app = express()
const port = 4550
const jsonParser = bodyParser.json()
const corsOptions = {
origin: 'http://example.com',
optionsSuccessStatus: 200
};
const corsMiddleware = cors(corsOptions)
app.get('/', (req, res) => res.send('Hello World!'))
app.get('/users', (req, res, next) => {
res.send('respond with a resource1');
});
app.options("/users", corsMiddleware)
app.post('/users', corsMiddleware, jsonParser, (req, res, next) => {
// data is in `req.body` (which will have a `value` property because the object on the client does)
res.send('respond with a resource2');
});
app.listen(port, () => console.log(`Example app listening on port ${port}!`))
(The above is untested and may have minor errors in it)
Please send serialized data as below:
const http = new XMLHttpRequest();
const url = 'http://localhost:4550/users';
const data = JSON.stringify("hey");
http.open("POST", url);
http.setRequestHeader("Content-Type", "application/json");
http.send(data);
You need to use bodyParser package
npm install body-parser
const bodyParser = require("body-parser");
and before setting up routes use it as below :
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
Don't forget to allow the headers declaration as below :
app.use((req, res, next) => {
res.setHeader("Access-Control-Allow-Origin", "*");
res.setHeader(
"Access-Control-Allow-Headers",
"Origin, X-Requested-With, Content-Type, Accept"
);
res.setHeader(
"Access-Control-Allow-Methods",
"GET, POST"
);
next();
});
and now you can read your data as below
router.post('/users', (req, res, next) => {
console.log(req.body);
});
I would update my client side view every insert in the database.
In y angular application I have a function that adds text to database :
ajoutText(newtext: String) {
this.dataService.sendtext(newtext)
.subscribe(res => this.socket.emit('save-message', { data: "hello" }));
}
after posting message to database I emit a socket. the idea is to trigger a get route to update my observable in Angular side with the new data, and create a data stream.
Here's my server configuration :
server.js:
var http = require("http");
var admin = require('firebase-admin');
var firebase = require("firebase");
var express = require("express");
var app = express();
var bodyParser = require("body-parser");
var port = process.env.app_port || 8080; // set our port
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
var server = app.listen(port);
var io = require("socket.io")(server);
var routerProj = require("./routes/routes");
app.use(function (req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header('Access-Control-Allow-Methods', 'GET, POST, PUT ,DELETE');
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept,*");
next();
});
var config = {
... configuration...
};
firebase.initializeApp(config);
var serviceAccount = require("./ServiceAcountKey.json");
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: "https://datatable-18f93.firebaseio.com"
});
app.use(function (req, res, next) {
req.io = io; // pass socket to route
next();
});
app.use("/v1", routerProj);
and routes.js file :
var express = require("express"); // call express
var router = express.Router(); // get an instance of the express Router
var admin = require("firebase-admin");
//module.exports = function (req) {
//router.route("/")
router.use(function (req, res, next) {
// Test
console.log(req.io.sockets)
next();
});
router
.route("/")
.get(function (req, res, err) {
// Get a database reference to our posts
var db = admin.database();
var ref = db.ref("/");
// Attach an asynchronous callback to read the data at our posts reference
ref.once("value", function (snapshot) {
var list = [];
snapshot.forEach(function (elem) {
list.push(elem.val());
})
list = JSON.stringify(list);
res.send(list);
}, function (errorObject) {
console.log("The read failed: " + errorObject.code);
res.status(500).send(errorObject.code);
});
});
router
.route("/")
.post(function (req, res, err) {
console.log(req.body);
// Get a database reference to our posts
var db = admin.database();
var ref = db.ref("/");
// Attach an asynchronous callback to read the data at our posts reference
ref.push(
{
"text": req.body.text
}
);
});
//return router;
//}
module.exports = router;
How can I run post route on save-message emit from client side ?
I would send data from angular to Express.
in my service ;
sendtext(text): Observable<any> {
console.log(text);
return this.http.post<string>(this.url, text, httpOptions);
}
I configure headers
const httpOptions = {
headers: new HttpHeaders({
'Content-Type': 'application/x-www-form-urlencoded'
})
my console.log(text) prints me the right text typed in an input.
In my server side I have created my server.js file
var http = require("http");
var admin = require('firebase-admin');
var firebase = require("firebase");
var express = require("express");
var app = express();
var routerProj = require("./routes/routes");
var bodyParser = require("body-parser");
var port = process.env.app_port || 8080; // set our port
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
var server = app.listen(port);
app.use(function (req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header('Access-Control-Allow-Methods', 'GET, POST, PUT ,DELETE');
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept,*");
next();
});
var config = {
......configuration...
};
firebase.initializeApp(config);
var serviceAccount = require("./ServiceAcountKey.json");
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: "https://datatable-18f93.firebaseio.com"
});
app.use("/v1", routerProj);
//Create HTTP server and listen on port 8000 for requests
// Print URL for accessing server
console.log("Server running at http://127.0.0.1:8080/");
And I have created my router file:
var express = require("express"); // call express
var router = express.Router(); // get an instance of the express Router
var admin = require("firebase-admin");
router
.route("/")
.post(function (req, res, err) {
console.log(req.body);
// Get a database reference to our posts
var db = admin.database();
var ref = db.ref("/");
// Attach an asynchronous callback to read the data at our posts reference
ref.push(
{
"text": req.body
}
);
});
module.exports = router;
Here console.log(req.body) prints an empty object {}
Is it because of the headers ? if yes how can I configure them ? I have already tried'Content-Type': 'application/json', and without headers, no result.
I would use socket.io in my routes file.
I have found multiple methods but no one worked for me.
Now I'm trying this solution
var http = require("http");
var admin = require('firebase-admin');
var firebase = require("firebase");
var express = require("express");
var app = express();
var bodyParser = require("body-parser");
var port = process.env.app_port || 8080; // set our port
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
var server = app.listen(port);
var io = require("socket.io")(server);
var routerProj = require("./routes/routes")(io);
app.use(function (req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header('Access-Control-Allow-Methods', 'GET, POST, PUT ,DELETE');
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept,*");
next();
});
var config = {
XXX
};
firebase.initializeApp(config);
var serviceAccount = require("./ServiceAcountKey.json");
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: "https://datatable-18f93.firebaseio.com"
});
app.use("/v1", routerProj);
//Create HTTP server and listen on port 8000 for requests
// Print URL for accessing server
console.log("Server running at http://127.0.0.1:8080/");
io.sockets.on("connection", function (socket) {
console.log("a user is connected");
});
Routes.js
var express = require("express"); // call express
var router = express.Router(); // get an instance of the express Router
var admin = require("firebase-admin");
module.exports = function (io) {
/*router.use(function (req, res, next) {
// do logging
io.on('connection', function (socket) {
console.log('User has connected to Index');
});
});*/
router.use(function (req, res, next) {
io.on('save-message', function (socket) {

sockets are working in my server.js file , in console I get the message :"a user is connected" when I run my angular app.
But in my browser I run http://127.0.0.1:8080/v1in router.js console.log is not working, so sockets is not getting passed.
I have tried to emit an event :
ngOnInit() {
this.socket.emit('save-message', { room: "hello" });
}
In my router.js :
router.use(function (req, res, next) {
io.on('save-message', function (socket) {
console.log('User has connected to Index');
});
});
console.log don't print anything.
var search = 1 + req.url.indexOf('?'); throws an error saying the statement to my left is undefined. Im using passportjs to create a login/registration page on my angular frontend. trying to make a post request to nodejs results in the above error. Im entirely new to the mean stack and ive tried several different tutorials to get myself up and running but have had some road blocks. can someone point in the right direction?
I've played around with just about every file moving around code and trying different solutions but nothing works, or one problem is solved but another occurs.
