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...
