Super useful CLI utility to count lines of code of basically any language 👌 It can also output results in other formats like JSON, CSV or YAML.

This one is convenient if you want to store data in JSON but you also need to work with attributes like with regular attributes.

It also has some "finders" that simplify query code.

oh, don't like this gem. I think it's too complex and not very flexible.

I prefer to just write "render json: ..."

I really love Sinatra simplicity to start new web services, it's a really smooth and easy process! I also use it currently in production. It makes a lot of sense (from a performance POV) for APIs and Proxies. But if you're going to build a more complex web app, with views, forms, mails, interactions, ... I'd just start with Rails.

Amazing tool.

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.
