Great library if you want to add feature flags to your app. I like the flexibility and ability to fully/partially/specifically enable features.

Amazing gem to integrate powerful search capabilities into your Rails application, on top of Elasticsearch. I recently used it to build a global "cross-model" smart search for a CRM. It even supports useful features, like: misspellings, suggestions, stemming, ... and can reindex data with no downtime.

A good gem to create a simple PDF, but the main risk I see is that the last release of the gem happened in 2020. Also, you cannot "edit" PDFs with it. So in my case I used "hexapdf" gem

Sidekiq-Cron is a very helpful gem for setting up and managing recurring jobs with Sidekiq. It makes scheduling cron jobs easy and supports both cron expressions and natural language formats. The Web UI is simple to use, and the gem offers great features like second-precision scheduling and timezone customization. A great tool for anyone managing background jobs in Ruby on Rails apps!

I've been building Rails apps for more than 10 years and I feel like I have superpowers now 💪 No, seriously. Building web-apps with Rails makes you really productive.

The latest major version, Rails 7, also simplified the front-end part, which makes super easy to use modern/ES6 stuff, even without Node and a the extra build step.

An excellent gem to mock (and "record") your requests in the specs.

Sometimes a bit annoying to re-record cassettes, but not a big deal.

Every Ruby/Rails dev must know this gem.
