What is the best framework for my project?

Choosing the right framework it’s not an easy task, there are a lot of good frameworks. Some of them are better than the others in a particular task and vice versa. I am going to compare four frameworks in order to choose one of them.

Express

Express only require a basic undertanding of node.js.
URL-based routing mechanism using HTTP
Robust and scalable
Easy learning curve
Provides plugins to boost its functionality

Sails

Auto-generate REST API
Integration of Express for HTTP
ORM for framework compatibility with databases
Support web socket

Nest

Ensure modular architecture for complete development flexibility
High compatibility with Angular on the frontend
CLI for a modular structure & features
Flexible

Fastify

Provides APIs working with routes, middleware, req/res validation…
Provides extensibility via hooks, plugins, and decorators.
Suitable for JSON schema
Easy way to use loggers.

Time comparison

Considering the previous facts, I’m going to choose between Express and Fastify. I have implemented HU:01, 02 and 07 to compare times.

Express code and benchmark

const express = require('express');
const app = express();

const port = process.env.port || 8080

const MyOutlet = require('./myoutlet.js');
const Item = require('./item.js');
let myoutlet = new MyOutlet();

var bodyParser = require('body-parser')
app.use( bodyParser.json() );       // to support JSON-encoded bodies
app.use(bodyParser.urlencoded({     // to support URL-encoded bodies
  extended: true
}));

app.get('/', function (req, res) {
    res.status(200).json('API is running');
});

app.get('/item/:brand', function(req,res){
  let brand = req.params.brand;
  try{
    res.status(200).json(myoutlet.brandInfo(brand))
  }catch(error){
    res.sendStatus(400)
    throw error;
  }
})

app.route('/item')
  .get(function(req,res){
    try{
      res.send({'Items': myoutlet.showItems()});
    }catch(error){
      res.sendStatus(404)
      throw error;
    }
  })

  .post(function(req,res){
    let type = req.body.type;
    let size = req.body.size;
    let brand = req.body.brand;
    let color = req.body.color;
    let price = req.body.price;
    let season = req.body.season;
    try{
      let item = new Item(type,size,brand,color,price,season)
      myoutlet.addItem(item);
      res.sendStatus(201)
    }catch(error){
      res.sendStatus(400)
      throw error;
    }
  })


app.listen(port);
console.log('Server running at localhost:'+port+'/');

module.exports = app

GET /item

Requests per second: 1362.49
Time per request: 73.395ms

GET /item/:brand

Requests per second: 1389.16
Time per request: 71.986ms

Fastify code and benchmark

const MyOutlet = require('./myoutlet.js');
const Item = require('./item.js');
let myoutlet = new MyOutlet();

const fastify = require('fastify')({logger: true})

fastify.register(require('fastify-formbody'))

const start = async () => {
    try {
      await fastify.listen(8000)
    } catch (err) {
      fastify.log.error(err)
      process.exit(1)
    }
}

fastify.get('/', async (req, res) => {
    return { aplicacion: 'MyOutlet' }
})

fastify.get('/item', async (req, res) => {
  try{
    return ({'Items': myoutlet.showItems()});
  }catch(error){
    res.code(404)
    throw error;
  }
})

fastify.post('/item', async (req, res) => {
  let type = req.body.type;
  let size = req.body.size;
  let brand = req.body.brand;
  let color = req.body.color;
  let price = req.body.price;
  let season = req.body.season;
  try{
    let item = new Item(type,size,brand,color,price,season)
    myoutlet.addItem(item);
    res.code(201)
  }catch(error){
    res.code(400)
    throw error;
  }
})

fastify.get('/item/:brand', async (req, res) => {
  let brand = req.params.brand;
  try{
    return ({'Items/brand': myoutlet.brandInfo(brand)});
  }catch(error){
    res.code(400)
    throw error;
  }
})


const close = async () => {
    try {
      await fastify.close()
    } catch (err) {
      fastify.log.error(err)
      process.exit(1)
    }
}
start()

module.export = start;
module.exports.close = close;
