More or less I found hapi to be similar to express only, few differences rest it does everything same as to express, the transition from express is difficult as with express we have middleware and is missing in this one. People have mix opinion over the performance of API, personally, I haven't seen any boost in performance its just like express. Documentation is great, plugin structure is what makes it easy and less chaotic. Overall its good alternative to express but if you are already using express as your framework and thinking of migrating it to hapi, don't do it, it's not worth the effort.

It is similar to express framework but comes with many build-in features which makes it special. It has many plugin available which can be used based on the project requirements. We can easily implement Authentication, API documentations with swagger any many other things using those plugins. It has a very huge community and documentation is also very good. Latest version of HAPI comes with async/await support, which is very helpful for clean and fast development.

This is one of the best package to create APIs when using with Node.It is quite similar to Express.js but still a bit different. With hapi there is no need to use middleware. - Documentation is quite good and well maintained - Backed by Walmart

The Hapi js ecosystem is well documented, well maintained, and battle-tested (came out of Walmart Labs). More opinionated than express, less than a framework like sails or loopback. A great starting point for a web app or api in node.

Its the first nodejs framework I have worked on. The security of hapi is way better than even the no. 1 competitor of hapi (express). And its tight integration with Joi schema validation provides better experience for the developers.
