Getting Started with hapi.js

Overview of this book

This book will introduce hapi.js and walk you through the creation of your first working application using the out-of-the-box features hapi.js provides. Packed with real-world problems and examples, this book introduces some of the basic concepts of hapi.js and Node.js and takes you through the typical journey you'll face when developing an application. Starting with easier concepts such as routing requests, building APIs serving JSON, using templates to build websites and applications, and connecting databases, we then move on to more complex problems such as authentication, model validation, caching, and techniques for structuring your codebase to scale gracefully. You will also develop skills to ensure your application's reliability through testing, code coverage, and logging. By the end of this book, you'll be equipped with all the skills you need to build your first fully featured application. This book will be invaluable if you are investigating Node.js frameworks or planning on using hapi.js in your next project.

Chapter 2. Adding Functionality by Routing Requests

In the last chapter, we saw what a sample route looks like in both vanilla Node and hapi, and how hapi is more configuration-oriented in its routing definition. In this chapter, I will expand on how hapi handles routing, making it easy to add routes in a scalable manner while being able to avoid making unnecessary mistakes. If you haven't got much experience with building web servers, this chapter will also be a good foundation in routing, covering the following topics:

  • Adding and configuring routes in hapi

  • The hapi routing algorithm

  • The hapi request life cycle

  • The hapi request object

  • The reply interface

  • Serving static files

  • Using templating engines to serve view

By the end of this chapter, you will have the tools that you need to be able to create a JSON API, a static file server, and a fully functional website using a templating library. You will also be shown some patterns to simplify less trivial requests, so the control flow won't become a...
