Project Overview
How The Project Came Together.
A full-stack Markdown to HTML converter featuring both a CLI tool and a live web application. This project demonstrates Python backend development, serverless deployment, and frontend integration: - CLI Tool: Command-line interface supporting single file and batch conversions with customizable options for themes, table of contents, and output formatting. - Web Application: Real-time browser-based converter with live preview, file upload support, and instant HTML download functionality. - Markdown Parser: Custom-built regex-based parser supporting headers (h1-h6), bold, italic, links, images, ordered/unordered lists, code blocks with syntax highlighting, blockquotes, and horizontal rules. - Theming System: Professional light and dark themes with GitHub-flavored styling, CSS custom properties, and responsive design. - Table of Contents: Automatic TOC generation from document headers with anchor links for easy navigation. - Testing: Comprehensive test suite with 73 unit tests covering parser and converter functionality.
