A clean,fast,efficient and the RIGHT way to configure routes in express.js

Installation

$ npm install righty

Features

• Cleaner code
• Configuration over code (inspired greatly from Hapi)
• Validations using Joi
• Automatic swagger documentation generation
• Body parsing support (json,urlencoded,multipart-formdata)

Quick Start

var express = require('express');
var app = express();
var Joi = require("joi");

var router = require("righty").Router();    // router instance

var Righty = require("righty")({
    defaultContentType : "json",
    swagger : {
        title : "Demo app",
        version : "v1",
        description : "Swagger docs for demo app. Generated using `righty`",
        schemes : ["http"],
        host : "localhost:3000"
    }
});                                       // righty instance

function SendMessageCtrl(req,res) {

    
    // req.body = > { data : "xyz"}
    
    res.send({
        message : "Sent"
    });
}

function ReceiveMessageCtrl(req,res) {

    res.send({
        message: "OK",
        data: ["Hi Foo", "Is Bar der?"]
    });
}


var routeMapping = [

    {
        path : "/message",
        method : "post",
        validate : {
            body : {
                data : Joi.string().max(250)
            }
        },
        handler : SendMessageCtrl
    },

    {
        path : "/message",
        method : "get",
        handler : ReceiveMessageCtrl
    }
];                           

router.add(routeMapping);           // add routes to router

app.use(express.static(__dirname+ '/public'));       // Note : You need to declare public directory as static if swagger documentation required

Righty.use(app,router);          // attach router to app

app.listen(3000);

API

Righty

Exposed by require('righty').

Righty(options)

Creates a new Righty instance.

var Righty = require("righty")({
    defaultContentType : "json",
    swagger : {
        title : "Demo app",
        version : "v1",
        description : "Swagger docs for demo app. Generated using `righty`",
        schemes : ["http"],
        host : "localhost:3000"
    }
});      
  

options

An options object containing following keys has to be passed to instantiate Righty:

• defaultContentType - The content types to be used for routes, for which content type is not explicitly mentioned. Supported content types (for now) are "json", "urlencoded" and "multipart"

• swagger - an optional object specifying swagger configuration. If omitted, documentation will not be generated. It may contain following keys:

  • title - title of the documentation. Required
  • version - version of the documentation. Required
  • description - description of the documentation. Optional
  • schemes - The transfer protocol of the API. Values MUST be from the list: "http", "https", "ws", "wss". If the schemes is not included, the default scheme to be used is the one used to access the Swagger definition itself. Optional
  • host - The host (name or ip) serving the API. This MUST be the host only and does not include the scheme nor sub-paths. It MAY include a port. If the host is not included, the host serving the documentation is to be used (including the port) . Optional

Note: You need to declare public directory as static if swagger documentation is required.

Righty.use(app,router)

It mounts Righty router (see below) to express app.

Righty.Router()

Creates a new Righty router instance

var router = require("righty").Router();     
  

router.add(routeMapping)

It mounts route(s) to a Righty router instance. It takes routeMapping as a single argument. routeMapping can be an object or an array of similar objects.

routeMapping

A routeMapping object contains following keys:

• path - Route path as used in Express. Required
• method - HTTP method of the request, such as GET, PUT, POST, and so on, in lowercase. Required
• contentType - The content type to be associated with the route. If omitted, defaultContentType is used. Optional
• handler - standard express middleware to be called to generate the response after successful body parsing and validation. Required
• validate - Object containing validation rules. Optional
  • body - Joi schema object. Optional
  • query - Joi schema object. Optional
  • params - Joi schema object. Optional
  • headers - Joi schema object. Optional
  • files - object containing file names as keys and filePropSchema (see below) as values. Optional

filePropSchema

It is an object containing file validation rules:

• mimetype - an array of mime-types to be used as filter for the file. Patterns like '*/*', "image/*", etc. are accepted. Required
• size - Maximum size allowed for files in bytes. Optional

Example where routeMapping is an object:

var router = require("righty").Router();   
  
var controllers = require("../controllers");  

var routeMapping = {
            path : "/profile/:id",
            method : "put",
            validate : {
                body : {
                    name : Joi.string(),
                    gender : Joi.any().valid("m","f")
                },
                headers : {
                    "x-authorization" : Joi.string()
                },
                query : {
                    askForAcknowledgement : Joi.number().valid(0,1),
                },
                params : {
                    id : Joi.number().integer()
                },
                files : {
                    pic : {
                        mimetype : ["image/*"],
                        size : 50000
                    }
                }
            },
            contentType : "multipart",
            handler : controllers.ProfileUpdateCtrl
};

router.add(routeMapping);

module.exports = router;
  

Example where routeMapping is an array:

var router = require("righty").Router();   
  
var controllers = require("../controllers");  

var routeMapping = [
    {
            path : "/profile/:id",
            method : "put",
            validate : {
                body : {
                    name : Joi.string(),
                    gender : Joi.any().valid("m","f")
                },
                headers : {
                    "x-authorization" : Joi.string()
                },
                query : {
                    askForAcknowledgement : Joi.number().valid(0,1),
                },
                params : {
                    id : Joi.number().integer()
                },
                files : {
                    pic : {
                        mimetype : ["image/*"],
                        size : 50000
                    }
                }
            },
            contentType : "multipart",
            handler : controllers.ProfileUpdateCtrl
    },
    {
                path : "/profile/:id",
                method : "get",
                validate : {
                    params : {
                        id : Joi.number().integer()
                    }
                },
                handler : controllers.ProfileViewCtrl
        }
    
];

router.add(routeMapping);

module.exports = router;
  

router.add(basePath,subRouter)

An alternate version of router.add() to facilitate hierarchical routing. subRouter is a normal Righty router and basePath is the path prepended to all the routes in subRouter.

Check out this full blown project which illustrates hierarchical routing.

UPDATE

Now handler can be either middleware or an array of middlewares.
