express-route-controller2

express-route-controller2

This is a helper function to assign controller actions to routes in express based on express-route-controller.

It provides just a structure on top of a normal express app, but also doesn't get in the way at all, and you can continue to use express normally and define even more routes manually if you wish. It's focused to help in the creation of APIs.

Usage:

In your express project install express-route-controller2:

npm install express-route-controller2

Now create a folder where you want all your controllers, eg. controllers, and add a file in there, named mycontroller.js. Then define it somehow, like so:

module.exports = {
    create: function(req, res) {
    },
    update: function(req, res) {
    },
    read: function(req, res) {
    },
    delete: function(req, res) {
    },
    validate: function(req, res, next) {
    }
};

In your main app.js file (or wherever you set up express routes normally) simply call the helper function (very sparse demo express app):

var express = require('express');
var app = express();
var erc2 = require('express-route-controller2');

// set up express route control:
erc2(app, {
  controllers: __dirname + '/controllers',
  routes: {
    "/grades": "mycontroller#read", // method: get
    "/notices/:id": { 
      "get": "mycontroller#read",
      "delete": "mycontroller#delete",
      "put": {
        "middleware": "mycontroller#validate", // this could be an array eg: ["mc#1", "mc#2"]
        "handler": "mycontroller#update"
      }
    }
  }
});

app.listen(3000);

You can make this even more easier, by defining your routes in a routes.json file, like so:

{
  "/grades": "mycontroller#read", 
  "/notices/:id": { 
    "get": "mycontroller#read",
    "delete": "mycontroller#delete",
    "put": {
      "middleware": "mycontroller#validate",
      "handler": "mycontroller#update"
    }
  }
}

And loading the routes is as simple as:

...

erc2(app, {
    controllers: __dirname + '/controllers',
    routes: require('routes.json')
});

...
