Byebug VS Ruby on Rails

Just pry or with byebug? If the latter: https://github.com/deivid-rodriguez/byebug/issues/564

Byebug is not fully compatible with Zeitwerk, I was getting random NameError exceptions failing to load constants in development and tests until I removed this gem.

byebug - this elevates debugging Ruby applications. It allows you to run a program line by line, add breakpoints, and evaluate and track values at runtime. If you still use puts for debugging, it's time you get to know Byebug's features and commands.

Immune from the compatibility issue with Zeitwerk

For debugging purposes, I recommend a few gems that will get you started and allow you to play with ruby code in your terminal and manage ruby gems. Gems like bundler pry and byebug do it good and you can check out the official docs, Pry, Byebug, Bundler, These gems need to be accessed globally.

Byebug is a helpful and easy-to-use debugger made for Ruby. It allows developers to use traditional debugging features to help identify what is happening in a program while it's running. Byebug was created by David Rodriguez in hopes of building a better Ruby debugger.

Others have been suggesting byebug, but for us it started causing random constant loading errors on Ruby 3 in Rails, due to Zeitwerk compatibility issues. So I'm quite happy that the debug gem came in as a replacement. I did like that pry-byebug allows stepping in a normal Pry console, I expect the debug gem will require some getting used to.

As far as debugging tools go, the Byebug and Pry are two of the best gems I have found. They are used in different contexts, but for all intents and purposes, including them in your code will halt an operation and allow you to access whatever point in the code you halted within your terminal with a REPL.

We commonly use byebug for debugging our code which is an easy-to-use, feature-rich ruby debugger. This gem is introduced in Rails 5. It offers features like Stepping, Breaking, Evaluating and Tracking.

Looking forward to this, byebug's Zeitwerk incompatibility is currently causing nondeterministic constant loading errors in our app when used with pry-byebug.

Here's a real life example: Imagine a Ruby on Rails app on which a team of developers are working. The code is hosted on GitLab and all the work is coordinated using GitLab issues. In other words: For every commit, there's an associated issue and the issue number acts as a sort of primary key for documentation, time reporting and so forth. This convention has a few advantages, most notably the ability to easily learn more about how, when and by whom features were implemented as well as how this implementation came to be.

Ruby on Rails is regarded as one of the best ruby frameworks. It was the primary language in developing big projects such as Twitter and helped the language boost the community. Often referred to as “Rails,” Ruby on Rails is a web development framework with an MVC control structure and currently running its 6.1 version. The 16-year-old language has dramatically influenced the web development structures and managing databases, web pages, and other components on a web application.

In Rails 7.1, a new option _instance_methods is introduced, allowing developers to opt-out of the automatic generation of instance methods for enums. When enum is defined with _instance_methods: false, Rails will no longer generate methods like pending?, processed?, etc.

Rails isn't super opinionated about database writes, its mostly left up to developers to discover that for relational DBs you do not want to be doing a bunch of small writes all at once.

That said it specifically has tools to address this that started appearing a few years ago https://github.com/rails/rails/pull/35077

The way my team handles it is to stick Kafka in between whats generating the records (for us, a bunch of web scraping workers) and and a consumer that pulls off the Kafka queue and runs an insert when its internal buffer reaches around 50k rows.

Rails is also looking to add some more direct background type work with https://github.com/basecamp/solid_queue but this is still very new - most larger Rails shops are going to be running a second system and a gem called Sidekiq that pulls jobs out of Redis.

I'm looking forward to see what extractions from this will land on rails. For example: https://github.com/rails/rails/issues/50454

Here is what strict_loading does (source):

Kamal is a wonderfully simple way to deploy your applications anywhere. It will also be included by default in Rails 8. Kamal is trivial, but I don’t recommend using it on your development machine.
