The Most Popular Ruby on Rails Debugging Tools

Here's a rundown of several popular debugging tools available for use with the Ruby on Rails framework.

1. The "byebug" gem is a powerful interactive debugging tool that allows developers to pause the execution of their code at any point, inspect and modify variables, and step through code line by line. It also supports post-mortem debugging and can be used to debug both the Rails application and its tests.
2. "pry-rails" is another popular gem that provides an alternative to the built-in Rails console. It allows developers to interact with their application and its objects in a more powerful and intuitive way, and also provides advanced features such as syntax highlighting and auto-completion.
3. "better_errors" is a gem that provides more detailed error pages for Rails applications, including interactive debugging and stack trace navigation.
4. "debugger" gem is another popular gem that is similar to byebug, but it provides a more traditional debugging experience. It allows developers to set breakpoints, step through code, and inspect variables in a similar way to a traditional debugger.
5. "rails-footnotes" is a gem that adds debugging information directly to the bottom of the browser window, including details about the current controller and action, as well as links to relevant source code.
6. "rack-mini-profiler" is a gem that provides detailed performance profiling for Rails applications, including information about database queries, view rendering times, and more.

In summary, these are some of the most popular debugging tools available for Ruby on Rails, each with its own strengths and use cases. Ultimately, the best tool for a given situation will depend on the specific needs of the developer and the application being debugged.
