Or… how to put OOP sauce in your functional backend Node is my first choice when I need to make backend services for mobile or web applications. While JS is not my favourite language the overall approach to backend development is much more pleasant than using other like EE or PHP.So, while I still waiting to see the official approach of Swift to server side development with the official (hope to see something later this year, maybe WWDC?), I try to experiment different patterns while I’m still writing the backend services for a new side project. tools Java Server APIs Group In this short post I want to share with you a little pattern I use to better handling service routes.The idea behind this pattern is to group each application context (authentication, user profile managment and any other specific application’s feature) in different classes which inherits from a base class. Router This class exposes a construct which takes as input the Express application and the base path where services for the route are exposed; also this class ha a property called where I’ll return the list of all services exposed by this specific route. services Let me show to you the base class: Router It’s very simple; we simply declare the list of all services which needs to be exposed by a base route, then assign a function (in form of express route, so ) which needs to be called. function route(req, res, next) {} For example our Auth subclass maybe: As you can see the path each route path is in the form: VERB: is the HTTP method which expose the call (if not specified is , otherwise you should specify if it’s a etc.) GET POST,PUT PATH: is the path of the service exposed (in the classic form of any Express request) While the value is the name of the function you should to implement in your subclass. At the end you can allocate and put in place your route as follows: Each service exposed by our is available under the /users/auth path (ie, ). AuthRouter http://server_url/users/auth/login/fb/xxxx It’s very easy to implement and a good way to make order in your Node backend.
