[javascript] How to redirect to another page in node.js

Ok, I'll try to help you using one my examples. First of all, you need to know I am using express for my application directory structure and for creating files like app.js in an automatically way. My login.html looks like:

...
<div class="form">
<h2>Login information</h2>
<form action="/login" method = "post">
  <input type="text" placeholder="E-Mail" name="email" required/>
  <input type="password" placeholder="Password" name="password" required/>
  <button>Login</button>
</form>

The important thing here is action="/login". This is the path I use in my index.js (for navigating between the views) which look like this:

app.post('/login', passport.authenticate('login', {
    successRedirect : '/home', 
    failureRedirect : '/login', 
    failureFlash : true
}));

app.get('/home', function(request, response) {
        response.render('pages/home');
});

This allows me to redirect to another page after a succesful login. There is a helpful tutorial you could check out for redirecting between pages:

To read a statement like <%= user.attributes.name %> let's have a look at a simple profile.html which has the following structure:

<div id = "profile">
<h3>Profilinformationen</h3>
    <form>
        <fieldset>
            <label id = "usernameLabel">Username:</label>
            <input type = "text" id="usernameText" value = "<%= user.user.username %>" />
            <br>
        </fieldset>
    </form>

To get the the attributes of the user variable, you have to initialize a user variable in your routing.js (called index.js in my case). This looks like

app.get('/profile', auth, function(request, response) {
    response.render('pages/profile', {
        user : request.user
    });
});

I am using mongoose for my object model:

var mongoose = require('mongoose');
var bcrypt   = require('bcrypt-nodejs');
var role     = require('./role');

var userSchema = mongoose.Schema({
    user             : {
        username     : String,
        email        : String,
        password     : String
    }
});

Ask me anytime for further questions... Best regards, Nazar
