Uptime Watcher 19.0: From Local Script to Deeply Tested Desktop App
· 8 min read
Uptime Watcher started as a pragmatic way to watch a handful of URLs from a local machine. By the time we reached v19.0.0, it had grown into a heavily-tested, architecture-driven Electron app with a full documentation and tooling ecosystem around it.
This post walks through that journey using real commits from the git history, focusing on three themes:
- How the architecture solidified around repositories, events, and IPC
- How the testing strategy evolved into strict, property-based coverage
- How documentation and tooling caught up with the rest of the stack
All examples and commit references are taken from the main branch as of 2025-11-25.
