Welcome to the ultimate guide on creating a dynamic shopping cart application using Angular 10, MDBootstrap, Firebase, and i18n! In this article, you’ll learn how to set up user registration, manage cart items, and implement drag-and-drop functionality. Grab your virtual toolbox, and let’s dive in!

Functionalities Overview

Before we get our hands dirty in code, let’s understand the core functionalities that we’ll implement:

• User Registration via Firebase Authentication (both Email/Password and Google Authentication).
• CRUD operations:
  • Users can add products to their cart.
  • Admins can add, edit, or delete products.
• Drag and Drop functionality using Angular CDK.
• Implement Authentication and Authorization for security.

Required Tools and Technologies

Here’s what you will be using:

• Technologies: HTML, MDBootstrap, CSS, Angular-10, Firebase, i18n, Drag Drop, Progressive Web Application, jsPDF.
• Database: Angular Firebase (Realtime Database).

Installation Steps

Let’s get started on the installation:

1. Angular CLI – Download Angular CLI
2. NodeJs – Download Node.js
3. Package Manager – Use NPM or Yarn.
4. Clone the repository and run npm install if you’re using npm, or yarn install if you’re using Yarn.
5. Follow an Angular + Firebase Tutorial.
6. Activate Firebase Authentication Providers (Email/Password and Google provider).
7. Update Firebase Realtime Database Rules:

rules: 
    {
      ".read": true, 
      ".write": true 
    }

8. Configure your Firebase settings in src/environments/firebaseConfig.ts:

export const FireBaseConfig = 
    { 
      apiKey: YOUR_API_KEY, 
      authDomain: YOUR_AUTH_DOMAIN, 
      databaseURL: YOUR_DATABASE_URL, 
      projectId: YOUR_PROJECT_ID, 
      storageBucket: YOUR_STORAGE_BUCKET, 
      messagingSenderId: YOUR_SENDER_ID 
    };

9. For Admin Role, register or sign in with Google Auth and set isAdmin to true.
10. Import the products JSON to the Realtime Database from Products JSON.
11. Run the server!

Understanding the Code: A Beginner’s Analogy

Imagine you’re building a physical shop where you manage various products. The Angular framework serves as your shop’s infrastructure, Firebase acts as your storage room for all products, and MDBootstrap embodies the stylish design of your shop. Just like a customer can select items to purchase, in our application, users have the capability to add items to their cart. As the shop owner, admins have special permissions to restructure the inventory, which parallels our CRUD operations.

Troubleshooting Tips

If you encounter any issues, here are some troubleshooting ideas:

• Ensure that Firebase Authentication is properly set up in your project settings.
• Double-check your Firebase configuration in the firebaseConfig.ts file to ensure all credentials are correctly inputted.
• Make sure your Realtime Database rules allow reads and writes.
• If your Angular application doesn’t load, check the console for any error messages and verify that your server is running by executing ng serve.
