Ruby on Rails advantages

  • RoR doesn’t let their creators sacrifice on security. They have a special section on their website for complaining and fixing security patches. RoR creators provide critical security features to come with the basic package for developers. They have update policies with the latest RoR security.
  • For 10+ years, they are still updating every now and then.
  • It is easier to build a website from scratch in Ruby on Rails.
  • Ruby on Rails has very little artificial complexity than any other language and framework.
  • The best part of RoR is its popular community. Through which many problems are sorted out very fast, new gems are added to public repositories every day.
  • Ruby on Rails is free of cost.  All necessary packages, open-source code libraries, support resources- all are free.
  • Developers save the time for debugging in late stages of development, all thanks to Ruby on Rails.
  • Pragmatism, along with Ruby, produces elegant solutions.
  • Ruby on Rails is very expressive as it is closer to the English language.
  • When it comes to the flexible convention for productivity, Rail comes with a small toolbox for agile development.
  • As there is a vast community of RoR, developers contribute a lot to these communities by creating and publishing new gems, which are also free to use and open source. One of the benefits of an active community is there will always be someone on Slack/Discord/Reddit to help you out.

Advantages in costing for Ruby on Rails

Ruby on Rails is famous for many readymade modules and plugins, which makes it easier for a programmer to use already written codes in it. RoR developers are 30 times faster than any other programming developer, lesser the time you take to code more money in your pocket.

Costing depends on these factors,

  1. How complicated is your application?
  2. Numbers of people working on RoR Application.
  3. The complexity of the application.

Ruby on Rails is an open-source framework that means it saves money on the framework itself. Hence it is cost-efficient.

CI services provide automated testing which ensures developer to avoids collision between new and old code, the average cost of such services per year is 300$-600$.

Debugging in Ruby on Rails

Debugging programming code from time to time is how professionals work, RoR makes debugging easier for developers. RoR forbade code execution at the breakpoint and marked that spot by keyword known as byebug. During execution, when it reaches the breakpoint, the marker will point the current so that the developer can write commands there. This gem offers a lot of other commands for e.g., next, step, break and continue. All gems have similar functions but different syntax and semantics.

Few tips and tricks for debugging includes,

  • During the production environment, use staging test servers for testing and checking your code.
  • The only way to fix production errors on the production site is it should be first fixed on the local machine and reproduce
  • To revert back to the old version, you must have backup each production version before pushing a new one.
  • You can fix production error only if,
    • Error is caused by specific dataset
    • Error is caused by deeper code bugs by the production dataset.
    • Error is caused by some server
