folder-router

Introduction

Folder-router is a tiny express router to get started with a new NodeJS project. You can put all your route files in a single directory, folder-router will be able to open and inject all your endpoint in your express instance. You can also put your file in sub directory and access it through sub-url.

Installation

You need NPM to install folder-router in your NodeJS project.

$ npm install --save folder-router

You can now use it in your main server file.
The first parameters must be your express instance, the second one must be the location of your routes directory. I highly recommand to use absolute location.

var app = require('express')();
var router = require('folder-router');
 
router(app, __dirname + '/routes');
 
app.listen(3000);

Creating your routes

In your routes directory, you can create as much as file as you want, everything will be read and add to express by folder-router. A route file MUST export a express.Router() instance as below :

routes/book.js

var Router = require('express').Router();
 
Router.get('/book', function(req, res) {
    res.end('All Books !');
});
 
Router.get('/book/:id', function(req, res) {
    res.end('Books with id = ', req.params.id);
});
 
Router.post('/book', function(req, res) {
    res.end('Adding a new book')
});
 
module.exports = Router;

Here is the list of all end points :

• GET http://localhost:3000/book
• GET http://localhost:3000/book/5
• POST http://localhost:3000/book

---

Also, you can create a directory "book" and write your routes like so :
routes/book/book.js

var Router = require('express').Router();
 
Router.get('/', function(req, res) {
    res.end('All Books !');
});
 
Router.get('/:id', function(req, res) {
    res.end('Books with id = ', req.params.id);
});
 
Router.post('/', function(req, res) {
    res.end('Adding a new book')
});
 
module.exports = Router;

The name of the file has no impact. The end point remains the same because it takes the name of the sub directory

---

One other solution for that, you can exports the base url with the root variable

routes/book.js

var Router = require('express').Router();
 
Router.get('/', function(req, res) {
    res.end('All Books !');
});
 
Router.get('/:id', function(req, res) {
    res.end('Books with id = ', req.params.id);
});
 
Router.post('/', function(req, res) {
    res.end('Adding a new book')
});
 
module.exports = Router;
module.exports.root = '/book'; // here
