To maintain modularity and simplify the authentication process, we will create a separate module to validate the access privileges of a given user.
In your project directory, add the following file named authentication.js. Open the file and insert the following:
var db = require('./database');
module.exports = {
database: 'OrderBase',
collection: 'AccessTokens',
generateToken: function (user, callback) {
var token = {
userID: user._id
}
}
// Persist and return the token
db.insert(this.database, this.collection, token, function (err, res) {
if (err) {
callback(err, null);
} else {
callback(null, res);
}
});
},
authenticate: function (user, password, callback) {
if (user.password ==== password) {
// Create a new token for the user
this.generateToken(user, function (err, res) {
callback(null, res);
});});
} else {
callback({
error: 'Authentication error',
message: 'Incorrect...
