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.

Foreword

hapi is a toolkit for web applications (and other HTTP servers) built by people with twice my experience and at least 10 times the smarts. They got the right team together and managed to work with the freedom to get it right this one last time—and they delivered.

hapi is also built by people who understand how to create, foster, and maintain a healthy and inclusive open source community, manage a responsible yet speedy release process, and be all around lovely people. If you are an end user or want to start contributing to the hapi ecosystem, you'll have great fun on your way with the clever technology and, even more so, with the great people.

From the first examples in the first chapter that you work through on your own to a fullfledged system that a large team can work on productively without stepping on each other's toes, Getting Started with hapi.js takes you on the journey to master everything you need to build everything from a hobby project to the most popular site on the Web.

The third step of my "usual process" of working with hapi is this: loving hapi even more.

I know you will, too.
