MarkdownPro is a modern, web-based Markdown editor and converter that combines powerful features with a sleek, user-friendly interface. Built for developers, writers, and Markdown enthusiasts, it offers a seamless experience from writing to final output.

Key Features

• Real-time Preview: Instant rendering of GitHub-flavored Markdown with split-screen view
• Multiple Export Formats: Convert Markdown to HTML, PDF, and Plain Text
• Auto-Save & Recovery: Automatic saving with data persistence and recovery mechanisms
• Modern UI/UX: Responsive design with light/dark theme support and smooth transitions
• File Operations: Drag-and-drop support, file import/export, and format conversion
• Performance Optimized: Web Workers for heavy processing and debounced updates

Tech Stack

• Frontend Framework: React with TypeScript
• Build Tool: Vite for fast development and optimized production builds
• State Management: React Query for async operations and local React state
• Styling: Tailwind CSS with Shadcn/ui components
• Storage: IndexedDB for large documents, LocalStorage for settings
• Performance: Web Workers for heavy computations

Implementation Highlights

Storage Strategy

• Two-tiered storage approach using LocalStorage for quick access and IndexedDB for larger documents
• Automatic data recovery and integrity checks
• Persistent user preferences and theme settings

Performance Optimizations

• Code splitting for optimized loading
• Debounced preview updates for smooth editing
• Web Workers for heavy parsing operations
• Efficient state management with React Query

    end

Future Roadmap

• Real-time collaboration features
• Advanced export templates
• Git integration
• Cloud storage sync
• Public API for developers
