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.

Composing applications from plugins


So far in this chapter, we've looked at how to create plugins, how to use third-party plugins in our applications, how to add communication between plugins, and how to create dependencies between plugins.

Plugins are a great way of managing your code base by splitting it up into smaller, more manageable chunks of functionality. But like every design strategy, plugins have some downsides. The downsides are mainly in the form of extra overhead when it comes to our registering and configuring them for our applications. In fact, configuration alone can be a big headache for applications. Let's look at how we can mitigate this.

When you think back to our index.js entry file from the last example, we simplified this by pushing all our business logic to plugins, making for a very readable and easy-to-follow entry file for new users of our codebase.

But now let's think about how this scales. As more functionality is added, the number of plugins would obviously grow...
