The sheer scale and massive number of developers using Rails has produced a large number of guides, tutorials, plugins, documentation, videos and anything that can help new and old Rails developers.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Small loading time
Since it has very few dependencies, the loading time for a Sinatra app is considerably small.
Pro Has only the bare minimum needed
Sinatra has taken an approach of having only the most useful components needed to build applications out of the box. It has simple routes along with a Domain Specific Language over a Rack layer.
Pro Massive community with lots of tutorials and guides
The sheer scale and massive number of developers using Rails has produced a large number of guides, tutorials, plugins, documentation, videos and anything that can help new and old Rails developers.
Pro Many plugins (gems) available
There are many third-party plugins (Ruby gems) available for Rails development. The larger ones and those that have a lot of downloads and users are very well documented and easy to use.
Pro Ruby is a nice readable language
Ruby has a very clean syntax that makes code easier to both read and write than more traditional Object Oriented languages, such as Java. For beginning programmers, this means the focus is on the meaning of the program, where it should be, rather than trying to figure out the meaning of obscure characters.
presidents = ["Ford", "Carter", "Reagan", "Bush1", "Clinton", "Bush2"]
for ss in 0...presidents.length
print ss, ": ", presidents[presidents.length - ss - 1], "\n";
end
Pro Good conventions
MVC is a great starting point, and perfect for APIs. You'll rarely if ever have to wonder "where should I put this code?"
Pro Small projects are very easy and it's possible to finish one in very little time
The large number of documentation, tutorials, videos and guides which help new developers who are just starting with Rails make it seem very easy to create a small and simple application by relying on code generation and components that come out of the box with Rails.
Pro Cool language
Pro Supported on every major cloud or VPS hosting service
Rails is supported on every major Cloud hosting service nowadays. There are also countless tutorials that help developers deploy their Rails apps if there are any problems on the way.
Pro Meta-programming capabilities
Cons
Con Hard to scale well
Because it's rather small and minimalistic, scaling up is not very easy with Sinatra. You need a great deal of knowledge on libraries and modules that may be useful for your particular use-case. As your application grows larger it may be hard to keep things clean and minimalistic, losing a lot of the advantages that Sinatra has.
Con Learning curve seems low at first, but starts becoming steeper
Rails' simplicity is deceptive. It's learning curve is really low at first, and the huge number of tutorials and guides out there for starting with Rails make it even easier. But it starts getting harder and harder as apps become more complicated. If good code conventions and OO design are not followed, then the codebase will be all over the place and it becomes impossible to maintain it.
Con Too much magic
So much behavior is implemented with dynamic behind-the-scenes changes to existing classes that obscure bugs are way too common. Conflicting interactions between multiple plugins that both try to change the same objects are a particularly pernicious example.
Con Too much convention
Con Not a very popular language outside of web development
Con Bad performance
Among the slowest frameworks. If you want to scale, you will have to migrate to another land.
