Ruby Gems

Just a general collection of gems I’ve known and loved (or want to try out).

Comparisons

• Coditsu will produce a diff between versions of a gem. Great if you want to see what’s changed, or need to do serious auditing of dependencies - run a bundle update, and then hit this for all the changes in Gemfile.lock
• RailsDiff will produce a diff between the output of rails new, handy for making sure you’re picking up new default configs as you roll the update train.

Code Coverage

• Debride finds uncalled methods
• Rcov measures coverage while running tests
• Coverband measures coverage in production

Commandline

• Github has a CLI

Database

• Bullet detects N+1 queries

Debuggers

• Byebug is my go-to for tracing, to step into function calls, skip to next line, and continue execution.
• Pry is the other really popular one.
• Jard looks interesting, provides a multi-window debugger environment, with a GUI stack trace, local variable dumps, threads, etc.
• Ruby is also getting a native debugger in 3.1 with more interesting breakpoints/callbacks that might prove useful for IDE integration.

Worker Queues

All these queues support ActiveJob in Rails

• Que leans heavily on Postgres-specific features for queue management, keeps it in the DB
• Resque is Redis-backed, includes a management site
• Sidekiq also Redis-backed, includes management site, and includes a Pro paid offering with some additional enterprisey features
