express-clean-routes

Easy to use library that helps to write clean routes for express applications.

Install

$ npm i -s express-clean-routes

Supported HTTP Methods

get post delete put

Clean route definition

const path = [
    {
        'path' : '/users/info',
        'method' : 'get',
        'middlewares' : [middleware.checkAuth],
        'handlers' : controller.getUserInfo
    }
]

'path' can take Dynamic Routes like:

 const path = [
     {
         'path' : '/users/:id',
         'method' : 'get',
         'middlewares' : [middleware.checkAuth],
         'handlers' : controller.getUserInfo
     }
 ]

'middlewares' can take multiple middleware functions:

 const path = [
     {
         'path' : '/users/:id',
         'method' : 'get',
         'middlewares' : [middleware.checkAuth, middleware.validateData],
         'handlers' : controller.getUserInfo
     }
 ]

Usage

express-clean-routes can be used with any project structure, here lets consider the following structure

.
+-- server
|   |
|   |
|   +-- controllers
|   |   +-- index.js
|   |   +-- users.js
|   |
|   +-- middlewares
|   |   |   +-- index.js
|   |
|   +-- public
|   |
|   +-- routes
|   |   +-- index.js
|   |   +-- users.js
|   |   +-- healthcheck.js
|   |
|   app.js
|
package.json

Setting up routes

The users.js file in routes directory:

const middleware = require('../middlewares')
const controller = require('../controllers/users')

const paths = [
    {
        'path' : '/users/info',
        'method' : 'get',
        'middlewares' : [middleware.checkAuth],
        'handlers' : controller.getUserInfo
    },
    {
        'path' : '/users/info',
        'method' : 'post',
        'middlewares' : [middleware.checkAuth, middleware.checkData],
        'handlers' : controller.processUserInfo
    }
]


module.exports = paths;

The healthcheck.js file in routes directory:

const middleware = require('../middlewares')
const controller = require('../controllers')

const paths = [
    {
        'path' : '/health/status',
        'method' : 'get',
        'middlewares' : [],
        'handlers' : controller.processStatus
    },
    {
        'path' : '/health/version',
        'method' : 'get',
        'middlewares' : [],
        'handlers' : controller.processVersion
    }
]


module.exports = paths;

The index.js file in routes directory:

var paths = [];

paths.push(require('./healthcheck'));
paths.push(require('./users'));

module.exports = paths;

Setting up the middlewares

The index.js file in middlewares directory:

const Middleware = {};

Middleware.checkAuth = (req, res, next)=>{
    if(req.query.fail === 'true'){
        return res.status(401).send({message:"Auth Failed"});
    }
    next();
};


Middleware.checkData = (req, res, next)=>{
    const body = req.body;
    if(!body.hasOwnProperty("first_name")){
        return res.status(400).send({message:"bad request"});
    }
    next();
};


module.exports = Middleware;

Setting up express to use express-clean-routes (Option 1)

Your app.js will look similar to this:

const express = require('express');
const http = require('http');
const cleanroutes = require('express-clean-routes');
const routes = require('./routes');

const app = express();

app.use(express.json());

app.use('/', cleanroutes(routes));

const server = http.Server(app);
const port = 3000;

server.listen(port, () => {
  console.log(`Express server running on port ${port}`);
});

Setting up express to use express-clean-routes (Option 2)

Your app.js will look similar to this:

const express = require('express');
const http = require('http');
const cleanroutes = require('express-clean-routes');
const routes = [];

const app = express();

app.use(express.json());

// include routes here
routes.push(require('./routes/healthcheck'));
routes.push(require('./routes/users'));
app.use('/', cleanroutes(routes));

const server = http.Server(app);
const port = 3000;

server.listen(port, () => {
  console.log(`Express server running on port ${port}`);
});

Setting up express to use express-clean-routes (Option 3)

Your app.js will look similar to this:

const express = require('express');
const http = require('http');
const cleanroutes = require('express-clean-routes');
const healthRouter = require('./routes/healthcheck');
const userRouter = require('./routes/users');

const app = express();

app.use(express.json());

app.use('/', cleanroutes([healthRouter, userRouter]));

const server = http.Server(app);
const port = 3000;

server.listen(port, () => {
  console.log(`Express server running on port ${port}`);
});
