How Losing My Typora License Led to Building My Own Markdown Editor
Introduction
For years, Typora has been my go-to Markdown editor — it’s affordable, reliable, and powerful. But yesterday, out of nowhere, it asked for my license key and threw an error claiming my usage limit was exhausted. While waiting on support to reply, I browsed free and open-source alternatives, but nothing quite clicked. Frustrated and impatient, I decided to take matters into my own hands last night and tasked Bob with building one from scratch. What started as a quick experiment quickly turned into a fully functional Electron app. Taking it a step further, I had Bob rewrite the entire application in Rust and package distributable builds for both versions. Today, both apps are completely open-source and ready to use — feel free to grab them!
Building the Desktop Foundation (Electron & React)
When building a high-performance desktop editor, selecting an extensible, cross-platform architecture is critical. The first edition of the Markdown editor was built using Electron, React 18, and TypeScript. This architecture decouples the main process handling system events and file storage from the isolated renderer process responsible for live preview rendering, syntax highlighting, and Mermaid diagram execution.
