## 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');
|
|
}
|
|
);
|
|
```
