In previous chapters, we studied and implemented Express framework. The Express community denotes it as minimalistic framework, and it thus provides performance benefits. For building any application, choosing the right framework is one of the most important factors for scalability of an application. In the case of Hapi, It has a different routing mechanism which boosts the performance of an application with its configurable pattern of code. It's always recommended that developers take into consideration all the benefits as well as downsides of any framework that it provides versus the functional implementation of application and its long-term goals. Let's understand the Hapi framework with the help of a small prototype.

The following steps give an incremental learning the experience of implementation of the Hapi framework using a phone book example. It is recommended to code as you read for better learning.
