Ranked in these QuestionsQuestion Ranking
Pros
Pro Comes bundled with a code reload tool
Revel comes bundled with a code reload tool which rebuilds the project on every file change. This code reload tool is also used to run, build and deploy the Revel application that you are building.
Pro Good examples easy to understand with simple emulated MVC behavior
Pro No need to find and install external libraries
Revel is a "batteries included" web framework, which means that a lot of features already come out of the box. This way you don't have to spend time and find third-party libraries to integrate to the framework for most of the tasks you need to complete.
Pro Easy to learn for fast development
Pro Backed by a major corporation
Hapi was developed and is still being used by Walmart. Being backed by such a major company means that it will not lose support any time soon and most importantly it's being developed by professionals and that you will always get support for it.
Pro Consistency across applications
Hapi's philosophy is that configuration is more important than code. This is especially useful for very large teams because it helps developers maintain consistency and reusability throughout their code.
Cons
Con Non-idiomatic code
Con Outdated
The world has moved past its MVC obsession. It's not the way the web works anymore. The good thing about go is that it's trivial to write a server applications (literally takes minutes). relying on a bloated, archaic framework is missing the point
Con Dead
Thankfully, this abomination is no longer being developed
Con No official support for mongo
Revel does not come with any support for MongoDB, you can integrate third-party libraries but they have been reported to crash under heavy load.
Con Requires too much boilerplate
Hapi seems to be made with large applications in mind. The sheer amount of boilerplate code it requires is simply not practical for a small web app. This also means that there are few examples of Hapi applications around for beginners to learn from.
