The ESLint configuration in Uptime Watcher is not small. With dozens of plugins and custom rules, understanding what is actually enabled can be painful.

To solve that, we integrated a static build of the ESLint Config Inspector directly into the Docusaurus site, so you can browse the current ESLint config as a web UI.

This post summarizes how that integration works and where to look if you want to extend or regenerate it.

Electron IPC is a common place where apps quietly rot: ad-hoc channels, mismatched payloads, and copy-pasted handlers that drift over time.

Uptime Watcher takes a different route. IPC contracts are treated as shared types, and we have scripts that fail the build when main and renderer drift apart.

This post explains how the IPC layer is structured, how static guards work, and how that shows up in the git history.

Property-based testing is not just a buzzword in this repo; it has caught real bugs in core monitor logic that traditional example-based tests missed.

This post walks through how we introduced fast-check, where we wired it in, and specific bug classes it exposed in Uptime Watcher.

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
