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.

Server routing


There are many ways to interpret a route in terms of web servers, but the easiest (or what I like to think of them as) one is the path that interacts with a particular resource on a web server. In most frameworks, including hapi, a route comprises three core properties:

  • the path through which you can access the route

  • a method by which you can access the path

  • a handler, which is a function to take an action based on the request and return the output to the user

In hapi, the handler looks like the following:

…
server.route({
  method: 'GET',
  path: '/',
  handler: function (request, reply) {
    return reply('Hello!');
  }
});
…

The preceding code should look familiar to the code sample of our server from the previous chapter. Again, like everything in hapi, we add a route by providing a configuration object with the required route properties. If any required properties are missing, the server will show an error on startup with a detailed error message, thus making it very easy to...
