A full‑stack ASP .NET Core MVC bookstore demo combining a playful front‑end with a robust admin console and complete shopping workflow. Key highlights include:

🛠️ Key Functionalities

🧑‍💼User Experience

• Dynamic starry background via Particles.js with custom GIF branding
• Full‑width banner carousel for promotions (Stripe deals, new arrivals, editor’s picks)
• “Ways to save and explore books” icon carousel styled like Amazon with arrow controls
• Responsive product grid: six‑column layout, hover zoom/shadow, discount ribbons, and split‑screen ad banners every 12 items
• AJAX‑powered shopping cart badge and live cart count
• Product Details page with quantity selector, role‑based add‑to‑cart, and real‑time price tiers

🔧 Admin Console (Authenticated Roles)

• Category Management: DataTables-powered table with pagination, search, “Create New Category” button, inline Edit/Delete actions (modal dialogs + SweetAlert2 delete confirmations).
• Product Management: DataTables CRUD list with warnings for incomplete uploads, create/edit/delete controls, and SweetAlert2 confirmation. Create/Edit pages feature TinyMCE rich-text editor for descriptions, input fields for Title, ISBN, Author, List Price and tiered pricing, Category dropdown, Cover Image & multiple Product Images uploads with file‑upload validation.
• User Management & Registration: Admin portal “Register” page to create new accounts with email, name, contact, address fields, and role selection. User List table with Name, Email, Phone, Company, Role columns and Unlock/Permission actions.
• Order Management: Filterable order list with status tabs and API endpoints; Order Details view showing pickup info and order summary; buttons for Start Processing, Ship Order, Cancel Order; Stripe Checkout integration with delayed vs. immediate payment, plus refund processing and real-time status updates.

🔑 Under the Hood

• Architecture: ASP .NET Core MVC, Entity Framework Core, repository & service layer patterns
• Front‑end: Bootstrap 5, jQuery, DataTables, Particles.js, SweetAlert2, Toastr.js, TinyMCE, FontAwesome
• Authentication/Authorization: ASP .NET Identity roles, Google reCAPTCHA v3 on admin register
• Payments: Stripe Checkout Sessions with delayed vs. immediate capture
• Dependency Injection for clean code separation and testability
