How to register a user using Node.js and MongoDB (using mongoose and Express.js)

Question

I need your help. I want to make a user registration form and use Nodejs, Express.js, MongoDB (mongoose) and give me a very simple example how to make a user registration form: Name, email address, password and mobile phone number :) I made a mongoose scheme and give such values. Name: req.body.name, but this will not work: / In my presentation, I did something bad.

this is my code, and if you think this is not correct, correct it. (Sorry for my bad english). this is server.js

var mongoose = require('mongoose'); mongoose.connect('mongodb://localhost/addressbookdb'); var express = require('express'); var app = express(); var db = mongoose.connection; app.use(express.static(__dirname + '/../client')); app.post("/",function(req,res){ res.end("Registration Succesfully Completed!"); var db = mongoose.connection; db.on('error', console.error.bind(console, 'connection error:')); db.once('open', function (callback) { console.log("connected.") }); // Schema var RegSchema = mongoose.Schema({ Name: String, Email: String, Pass: String, Num: Number, reg_time : { type : Date, default: Date.now } }, { collection: 'AddressCol' }); // Model var UserReg = mongoose.model('UserReg', RegSchema); // Add in collection var UserAdd = new UserReg({ Name: req.body.name, Email: req.body.email, Pass: req.body.pass, Num: req.body.num, }); // Save UserAdd.save(function (err, fluffy) { if (err) return console.error(err); }); }); app.listen(8000, function() { console.log("Server is running!"); }); 

and this is my html page:

 <div class="form-group"> <input type="text" class="form-control" id="name" placeholder="name><br> <input type="email" class="form-control" id="email" placeholder="Email"><br> <input type="password" class="form-control" id="pass" placeholder="Password"><br> <input type="number" class="form-control" id="num" placeholder="Number"><br> <button type="submit" class="btn btn-primary" id="reg-form-btn">Registration!</button> </div> <script> $(document).ready(function() { $("#reg-form-btn").click(function() { var name = $("#name").val(); var email = $("#email").val(); var pass = $("#pass").val(); var num = $("#num").val(); $.post("/", { Name: name, Email: email, Pass: pass, Num: num }); }); }); </script>

Perhaps you should consider a passport or other module. But you can do something like this:

 app.post('/signup', function (req, res, next) { var user = { Name: req.body.name, Email: req.body.email, Pass: req.body.pass, Num: req.body.num }; var UserReg = mongoose.model('UserReg', RegSchema); UserReg.create(user, function(err, newUser) { if(err) return next(err); req.session.user = email; return res.send('Logged In!'); }); }); app.post('/login', function (req, res, next) { var email = req.body.email; var pass = req.body.pass; User.findOne({Email: email, Pass: pass}, function(err, user) { if(err) return next(err); if(!user) return res.send('Not logged in!'); req.session.user = email; return res.send('Logged In!); }); }); app.get('/logout', function (req, res) { req.session.user = null; }); 

Then you should have middleware for authentication

 function isLoggedIn (req, res, next) { if (!(req.session && req.session.user)) { return res.send('Not logged in!'); } next(); } 

And use it on private routes

 app.get("/api", isLoggedIn, function (req, res) { //Something private })

Here is a good tutorial on how to do what you want using a very useful passport module. You can also quickly look at the mechanism of the Jade template, which can be useful in further exploring the creation of Express applications.

check out this tutorial ... you can ignore Angular and mongojs if you want: http://www.phloxblog.in/single-page-application-angular-js-node-js-mongodb-mongojs-module/#.Vc20OXW1Gkq

You are missing the body-parser . Try this in the server code:

 const bodyParser = require('body-parser'); app.use(bodyParser); 

Please refer to the question. How do I access the request body when sending POST using Node.js and Express?
