A comprehensive web-based Product Management System built with vanilla JavaScript that implements full CRUD (Create, Read, Update, Delete) operations. This application provides an intuitive interface for managing product inventories with advanced features like real-time calculations, search functionality, and persistent data storage.
- Create: Add new products with detailed information
- Read: Display all products in an organized table format
- Update: Edit existing product information seamlessly
- Delete: Remove individual products or clear all data
- Real-time Price Calculator: Automatic total calculation (Price + Taxes + Ads - Discount)
- Bulk Operations: Add multiple quantities of the same product
- Smart Search System: Search by product title or category
- Data Persistence: Uses localStorage to save data between sessions
- Input Validation: Ensures data integrity with validation rules
- Responsive Design: Clean, modern UI that works across devices
- Dynamic UI Updates: Real-time color changes based on input validity
- Smooth Animations: CSS transitions for better user interaction
- Form Auto-clear: Automatic form reset after operations
- Count Limitation: Maximum 100 items per product for performance
- Search Mode Toggle: Switch between title and category search
- HTML5: Semantic markup structure
- CSS3: Modern styling with dark theme and responsive design
- Vanilla JavaScript: Pure JavaScript without frameworks
- DOM Manipulation: Dynamic table generation and updates
- Event Handling: Click and keyup events for real-time interactions
- Local Storage API: Client-side data persistence
- Array Methods: Efficient data manipulation with splice, push, etc.
- Template Literals: Dynamic HTML generation
- Input Validation: Form validation with user feedback
Product Object: {
title: string,
price: number,
taxes: number,
ads: number,
discount: number,
total: calculated,
count: number,
category: string
}- Automatic total calculation:
(Price + Taxes + Ads) - Discount - Real-time updates as user types
- Visual feedback with color-coded total display
- Case-insensitive search functionality
- Dual search modes (title/category)
- Live filtering as user types
- Maintains original data integrity
- JSON serialization for localStorage
- Efficient array operations for CRUD functions
- Proper memory management with data cleanup
- Minimal DOM queries by caching elements
- Efficient table rendering with template literals
- Smart re-rendering only when necessary
- Optimized search with string includes method
