## Description
<section id='description'>
As a reminder, this project is being built upon the following starter project on <a href='https://glitch.com/#!/import/github/freeCodeCamp/boilerplate-advancednode/'>Glitch</a>, or cloned from <a href='https://github.com/freeCodeCamp/boilerplate-advancednode/'>GitHub</a>.
Now we need to allow a new user on our site to register an account. On the res.render for the home page add a new variable to the object passed along- <code>showRegistration: true</code>. When you refresh your page, you should then see the registration form that was already created in your index.pug file! This form is set up to <b>POST</b> on <em>/register</em> so this is where we should set up to accept the POST and create the user object in the database.
The logic of the registration route should be as follows: Register the new user > Authenticate the new user > Redirect to /profile
The logic of step 1, registering the new user, should be as follows: Query database with a findOne command > if user is returned then it exists and redirect back to home <em>OR</em> if user is undefined and no error occurs then 'insertOne' into the database with the username and password and as long as no errors occur then call <em>next</em> to go to step 2, authenticating the new user, which we've already written the logic for in our POST /login route.

```js
app.route('/register')
  .post((req, res, next) => {
    db.collection('users').findOne({ username: req.body.username }, function(err, user) {
      if (err) {
        next(err);
      } else if (user) {
        res.redirect('/');
      } else {
        db.collection('users').insertOne({
          username: req.body.username,
          password: req.body.password
        },
          (err, doc) => {
            if (err) {
              res.redirect('/');
            } else {
              next(null, user);
            }
          }
        )
      }
    })
  },
    passport.authenticate('local', { failureRedirect: '/' }),
    (req, res, next) => {
      res.redirect('/profile');
    }
  );
```
