hapi is a rock solid server framework for Node.js. Its focus on modularity and configuration-over-convention makes it the perfect match for any size development team. This video will introduce you to hapi by showing you the bare minimum needed to run a hapi server.

[00:00] The first thing we need to do is install Hapi. We'll do "npm install hapi --save," which will save it to the package.json file as a dependency. Next, I'll use nodemon to watch for changes to files in my project directory. Nodemon will automatically restart the server any time it detects a changed file.

[00:26] In my index.js file, I need to pull in the Hapi framework by requiring it and assign it to the variable "hapi." Next, I'll create a new instance of the Hapi server class, then add a connection which tells the server which host and port to listen on.

[00:48] To add a basic route, I'll use the server's route method and pass in a configuration object that tells the route how to behave. Every route configuration needs three things, a method that tells the router which HTTP verb or verbs to watch for, a path string for the URL to match, and a handler function to handle a request.

[01:07] The handler function takes two arguments, "request" and "reply." I'll just use "reply" to respond with a string of "Hello Hapi."

[01:18] The last thing we need to do is tell the server to start. Server.start takes a callback function, letting us know that the server has been started. I'll log the connection's URI here. Now, when I refresh the browser, it responds with the string "Hello Hapi."

I just get the PRO subscription and this is the first class I take. how come you guys keep content outdated on a paid site? most of this code doesn't make sense on the last versions of hapi.
