Building Authentication with passport.js Chapter 6

Now, when we save a user, we should create our own method to add users to the
database, as we want to encrypt their passwords. So, let's add the following code

to models/User.js:

const User = mongoose.model('User', UserSchema);

module.exports = User;

module.exports.createUser = (newUser, callback) => {

bcryptjs.genSalt(10, (err, salt) => {

bcryptjs.hash(newUser.password, salt, (error, hash) => {

// store the hashed password

const newUserResource = newUser;

newUserResource.password = hash;

newUserResource.save(callback);

});

});

};

In the preceding code, we have used the bcrypt library, which uses a genSalt mechanism

to convert a password into an encrypted string. The preceding method—createUser—in

the User model takes the user object, converts the user-provided password into a bcrypted

password, and then saves it to the database.

Adding API endpoint to register a user

Now that we have our model ready, let's move on to creating an endpoint to create a user.

For that, let's first create a controller called users.js in the controllers folder to

manage all user related requests. Since we have added a code block to initialize all the files

inside the controllers directory in server.js, we do not need to require those files

here.

In users.js, replace the file's contents with the following code:

const User = require('../models/User.js');

module.exports.controller = (app) => {

// 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({
