The Unofficial 37signals/DHH Rails Style Guide

About This Document

This style guide was generated by Claude Code through deep analysis of the Fizzy codebase - 37signals' open-source project management tool.

Why Fizzy matters: While 37signals has long advocated for "vanilla Rails" and opinionated software design, their production codebases (Basecamp, HEY, etc.) have historically been closed source. Fizzy changes that. For the first time, developers can study a real 37signals/DHH-style Rails application - not just blog posts and conference talks, but actual production code with all its patterns, trade-offs, and deliberate omissions.

Simplified getRelativeTimeString
// from https://twitter.com/Steve8708/status/1504131981444980739
// simplified to a function body of 8 tidy lines
// no loop needed, no 2d array of 3-tuples needed
// just 2 arrays, a findIndex call, and some indexing :)
