TypeError: Cannot read property 'username' of undefined from Form Submit
<p>I have a form being submitted, but I am unable to assign assign the form 'req.body' username and password properties to the database (no hash on the password, just trying to get a MEAN CRUD app working for starters).</p>

<p>My form is as follows:</p>

<p><strong>form</strong></p>

<pre><code>&lt;form action="/signup" method="post"&gt;
    &lt;input type="text" name="username" placeholder="Username" /&gt;
    &lt;input type="password" name="password" placeholder="Password" /&gt;
    &lt;button type="submit" value="Sign Up" /&gt;
&lt;/form&gt;
</code></pre>

<p><strong>user schema (./models/user.js)</strong></p>

<pre><code>var mongoose = require("mongoose");

var UserSchema = new mongoose.Schema({
    username: String,
    password: String
});

module.exports = mongoose.model('User', UserSchema);
</code></pre>

<p><strong>app.js (only showing reference to User model and "/signup" post function</strong></p>

<pre><code>var User = require("./models/user");
app.post("/signup", function(req, res) {
    var user = new User();
    user.username = req.body.username;
    user.password = req.body.password;
    user.save(function(err) {
        if (err) {
            res.send(err);
        }
        res.redirect("/profile", { message: 'User successfully registered!', data: user });
    });
});
</code></pre>

<p>When I run the application:</p>

<pre><code>node app.js
</code></pre>

<p>Everything runs fine. All endpoints, routes are working correctly.</p>

<p>However, when I click the submit button of the above form, I receive the following error in my Terminal:</p>

<pre><code>TypeError: Cannot read property 'username' of undefined
    at Layer.handle [as handle_request](/node_modules/express/lib/router/layer.js:95:5)
    at next (/node_modules/express/lib/router/route.js:131:13)
    at Route.dispatch (/node_modules/express/lib/router/route.js:112:3)
    at Layer.handle [as handle_request] (/node_modules/express/lib/router/layer.js:95:5)
</code></pre>

<p>How can I ensure that the <strong>req.body.username</strong> and the <strong>req.body.password</strong> successfully pass to the mongodb database?</p>

<p>Thanks for any help.</p>
