While working on a Ruby on Rails development project, a developer often gets confused with the gems. These are plug-ins or external libraries that enhance the functionality of a website developed on Ruby on Rails technology. Now the query most people search for is – when to use these gems!
Well, we need to take a lot of things in consideration. We need to understand the code base, examinations, quality, level of functionality, etc. How about going into the details? Okay! Let us do it.
When using gem in Ruby on Rails development
Here are some of the factors that suggest using a gem in a web application.
1. Gem’s code quality
You must use a rails gem only when it has a good quality coding. Those which are not readable and complex are best to be avoided. Instead, go for a better gem that is easily understandable and convenient to work upon.
2. The amount of effort required
Consider how much effort is required in adding modules. If the addition of modules in applications seems to be complicated, it’s better to opt for a Ruby gem.
Otherwise, a simple module can be easily written by experienced developers. In that case, gems are not required at all.
3. Gem with DSL that works
Again, it is better to choose a gem whose DSL seems suitable for working with. When you have different gems with almost similar functionality, this feature will help you to choose the right one.
