Building Authentication with passport.js Chapter 6// register a user
app.post('/users/register', (req, res) => {
const name = req.body.name;
const email = req.body.email;
const password = req.body.password;
const newUser = new User({
name,
email,
password,
});
User.createUser(newUser, (error, user) => {
if (error) {
res.status(422).json({
message: 'Something went wrong. Please try again after some
time!',
});
}
res.send({ user });
});
});
};Here, we have added a route for users login as /users/login which then uses
passport.js local authentication mechanism to log in the user to the app.
Also, we configured passport.js to use LocalStrategy when user logs in which takes the
username and password of the user.
Installing express-session
The next thing we need to do is setup a session so that when a user successfully logs in,
the user data can be stored in the session and can be retrieved easily when we make
other requests. For this, we need to add a package called express-session. Let's go ahead
and install the package with the following command:
$ npm install express-session --saveConfiguring express-session
Now, that we have the package, let's configure this package to fulfill our needs to save the
user in the session. Add the following lines of code in it.
