Ranked in these QuestionsQuestion Ranking
Pros
Pro Clean, simple route building
Growler improves on Scotty's route building functions, allowing hierarchical declarations rather than requiring each endpoint to be fully specified.
Pro Easy to pick up and use
A simple framework cuts development time and costs. To get started, developers only need to understand how to write routing and actions.
Pro Available on gitHub
Having the source code on gitHub means developers can easily suggest improvements and error reports. They also have a community that can help with any problems that come up.
Cons
Con Potentially unstable API
Growler is still at an experimental stage and users are warned that breaking changes may happen between versions.
Con Lacks features due to its small size
Since Scotty is small, it does not contain some features that a complex web application may need. Anything that Scotty can't provide must be either found or written, costing developers.
