Static Typing in Ruby with a Side of Sorbet
As an experiment to see how static typing could help improve our team’s Ruby experience, we introduced Sorbet into a greenfield codebase with a team of 4 developers. Our theory was that adding static type checking through Sorbet could help us catch bugs before they go into production, make refactoring easier, and improve the design of our code. The short answer is that yes, it did all of that!
How Ruby Can Surprise You
A nice list of quirks and specifics of Ruby that look confusing.
Gems
full_request_logger
Easy access to full request logs via a web UI. The recorder attaches to the existing Rails.logger instance, and captures a copy of each log line into a per-thread buffer. When the request is over, the middleware makes the recorder store all the log lines that were recorded for that request as a compressed batch to an auto-expiring Redis key.
bundle-diff
Bundler plugin for showing diffs of bundled gems against latest versions.
httpx
HTTPX is an HTTP client library for the Ruby programming language.
modulation
Modulation provides an alternative way of organizing your Ruby code. Modulation lets you explicitly import and export declarations in order to better control dependencies in your codebase. Modulation helps you refrain from littering the global namespace with a myriad modules, or complex multi-level nested module hierarchies.
lowkiq
Ordered background jobs processing.
tapping_device
Tapping Device is a gem built on top of Ruby’s TracePoint class that allows you to tap method calls of specified objects. The purpose for this gem is to make debugging Rails applications easier.
Tools

SWR
SWR is a React Hooks library for remote data fetching.
The name “SWR” is derived from stale-while-revalidate, an HTTP cache invalidation strategy popularized by RFC 5861.
SWR first returns the data from cache (stale), then sends the fetch request (revalidate), and finally comes with the up-to-date data again.
