FrankenMarkdown
TL;DR
FrankenMarkdown is a new Markdown engine that combines a clean-room parser, LaTeX-grade typesetting, and a custom PDF writer into a single Rust-based solution. It operates entirely in the browser using WebAssembly, allowing users to type Markdown and instantly see rendered HTML or PDF without any server interaction.
✦ Why It Matters
Engineers can implement client-side Markdown rendering in their applications to enhance user privacy and reduce server load.
Key Takeaways
- Explore using Rust for building client-side applications.
- Implement WebAssembly for efficient browser-based processing.
- Utilize URL fragments for sharing documents securely.
- Consider client-side rendering to improve user privacy.
Full Summary
FrankenMarkdown addresses the need for a robust Markdown rendering engine that operates entirely client-side, ensuring privacy and ease of sharing. Built with a clean-room parser and LaTeX-grade typesetting, it utilizes a Rust core that compiles to WebAssembly (WASM) for efficient execution in the browser.
Users can type Markdown on one side of the interface, while the engine renders it in real-time on the other side. The engine can also convert documents to PDF format without needing a backend server.
By compressing Markdown and encoding it in URL fragments, users can share documents without uploading them anywhere, maintaining complete control over their content. This solution supports documents up to approximately 30 KB, making it suitable for most Markdown use cases.
The implications for engineers include the ability to create fully client-side applications that respect user privacy while providing rich document rendering capabilities.
