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.

Probably the best gem if you need an HTTP client. I like that it constantly improving and I see new releases.

Also, I like that it has a nice feature -middleware support.

While it is probably the most customizable and flexible gem for file uploads, it might be too complex. I personally prefer to use a paperclip, carrierwave, or activestorage when I need to have just a simple file upload.

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

first

Best two things of Hugo:
- It's fast
- It has a lot of starters and themes
