+# Project Architecture
+
+## Overview
+
+This is a React-based developer tools web application built with TypeScript. The application provides various utility tools including timestamp conversion, timers, text comparison, JSON formatting, encoding/decoding, encryption, QR code generation, and IP address lookup.
+
+## Technology Stack
+
+- **Frontend Framework**: React with TypeScript
+- **Routing**: React Router v6
+- **UI Components**: Ant Design (antd)
+- **Build Tool**: Create React App
+- **Deployment**: GitHub Pages
+

+
+## Key Components
+
+### 1. Routing (src/router/Router.tsx)
+
+The application uses React Router v6 for client-side routing. The main routes include:
+
+- `/` and `/home` - Homepage
+- `/tools/*` - Tools layout with nested routes for individual tools:
+  - `/tools/timestamp` - Timestamp converter
+  - `/tools/timer` - Timer utility
+  - `/tools/textdiff` - Text comparison tool
+  - `/tools/json` - JSON formatting tool
+  - `/tools/encoder_decoder` - Encoding/decoding utilities
+  - `/tools/encryption` - Encryption/decryption utilities
+  - `/tools/qrcode` - QR code generator
+  - `/tools/ipaddress` - IP address lookup
+  - `/tools/cron` - Cron expression parser and scheduler
+
+### 2. Tools Layout (src/pages/ToolsLayout.tsx)
+
+The ToolsLayout component serves as the main layout for all tool pages with:
+
+- A horizontal navigation menu with tab items for each tool
+- Dynamic tab selection based on the current URL path
+- Content area that renders the active tool component via `<Outlet />`
+
+Key features:
+- Uses `useLocation` hook to track URL changes
+- Implements `useState` and `useEffect` to dynamically update the selected tab
+- Automatically activates the corresponding tab based on the URL path
+
+### 3. Individual Tool Components
+
+Each tool is implemented as a standalone component in the `src/components/tools/` directory:
+
+- **TimestampPanel** - Time conversion utilities
+- **TimerPanel** - Countdown and stopwatch functionality
+- **TextDiffTool** - Text comparison with visual highlighting
+- **JsonTools** - JSON formatting and validation
+- **EncoderDecoderTabs** - Multiple encoding/decoding formats
+- **EncryptionTabs** - Various encryption/decryption algorithms
+- **QRCodeGenerator** - QR code generation from text input
+- **IPAddressView** - IP address information lookup
+- **CronTool** - Cron expression parsing and schedule prediction
+
+## Data Flow
+
+1. User navigates to a URL (e.g., `/tools/json`)
+2. React Router matches the route and renders the `ToolsLayout` component
+3. `ToolsLayout` determines the active tab based on the URL path
+4. The corresponding tool component is rendered in the content area via `<Outlet />`
+5. User interacts with the tool, which manages its own state and UI
+
+## GitHub Pages Deployment
+
+The application is configured for deployment to GitHub Pages with special handling in `public/index.html` to support client-side routing:
+
+- Includes a script to handle redirects for single-page applications
+- Uses the `spa-github-pages` approach to ensure proper routing
+
+## State Management
+
+- Each tool component manages its own local state using React hooks
+- The ToolsLayout component manages the active tab state
+- No external state management library is used (e.g., Redux, Zustand)
+
+## Styling
+
+- Primarily uses Ant Design components for UI
+- Custom CSS is minimal and located in `src/App.css`
+- Responsive design through Ant Design's built-in responsive features
+
+## Build Process
+
+- Uses Create React App's default build process
+- Optimizes assets for production deployment
+- Outputs to the `build/` directory
