Karate Store is an e-commerce platform where users can purchase martial arts equipment and accessories. To ensure user security, it's essential to implement robust authentication mechanisms.
In this article, we will discuss the steps required to create a user registration and login system for Karate Store using Gitlab UI/CD. We will cover topics such as creating a user model, implementing user registration forms, and integrating with Gitlab's authentication API.
A user model is essential to store user data, including their username, password, email, and other relevant information. We can create a user model using Gitlab's built-in User model or implement our own custom model.
To create the user model, we need to define the structure of the data and methods required to interact with it. For example, we may need to define a method to hash passwords for secure storage.
User registration forms are essential to collect user information from users before creating an account. We can create user registration forms using Gitlab's UI/CD features or implement our own custom form.
To create the user registration form, we need to define a template with fields for username, email, password, and other relevant information. We can then use Gitlab's validation features to ensure that user input is valid.
Gitlab provides an authentication API that allows us to integrate our system with the Gitlab authentication service. We can use this API to authenticate users and redirect them to their profiles after login.
To integrate with the authentication API, we need to create a credentials file for Gitlab's API credentials and configure it in our code. We can then use the API credentials to authenticate users before redirecting them to their profiles.
// Create a user model
class User {
constructor(username, email, password) {
this.username = username;
this.email = email;
this.password = hashedPassword(password);
}
hashCode() {
return this.username + this.email;
}
}
// Define the hashing function for passwords
function hashedPassword(password) {
const salt = crypto.randomBytes(16).toString('hex');
const hash = crypto.createHash('sha256').update(salt + password).digest('hex');
return `hashed:${hash}`;
}
// Create a user registration form
const registerForm = document.getElementById('register-form');
function registerUser() {
const username = registerForm.username.value;
const email = registerForm.email.value;
const password = registerForm.password.value;
// Validate user input
if (username.length <3) { alert("Username must be at least 3 characters long"); return; } if (!email.match(/^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$/) || !password.match(/^(?=.*\d)(?=.*[@$!%*#?&])[A-Za-z\d@$!%*#?&]{8,}$/)) { alert("Invalid email or password"); return; } // Register the user fetch('/register', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ username, email, password }), }) .then((response) => response.json())
.then((data) => console.log(data))
.catch((error) => console.error(error));
}
Example login functionality using the credentials file for Gitlab's API credentials
To implement login functionality, we can use the credentials file for Gitlab's API credentials to authenticate users.
We can then redirect them to their profiles after login.
