How Pronto Works
Pronto doesn't use the MVC (Model View Controller) pattern prominent in many applications. There are several reasons for this, but the big one is simple: MVC isn't a terribly good fit for Node.js. If you really like MVC, you can actually reproduce it conveniently in Pronto.js, but the framework itself doesn't make you use it.
Instead, Pronto combines two other patterns: Front Controller and Chain of Command.
- Front Controller: This is basically the "router" part of most MVC implementations. In a nutshell, it sits at the front of the application and maps incoming requests to the code that can handle those requests.
- Chain of Command: This pattern takes a particular request and executes a series of commands in response. Each command builds on the previous command, thus they act like a "chain".
A First Pronto Project
To get started with Pronto using Node.js, give this a try. What we are going to do is build a very simple "Hello World" application. This doesn't get into the details of working with a context or writing your own commands, but it will help you get started.
