javascript - Deploying First Express.js App, Someone please tell me how bad my server logic is -

-

i deploy first express.js app , need tell me if messing up.

i running ubuntu ec2 using nginx proxy port 80 requests socket node.js app listening on.

to start app, using pm2. when wrote server app, included node.js cluster module fork , cluster needed. deployment time, see pm2 offers clustering.

here server pm2 running on production server:

confus.at('development', () => {     spawnworker() })  confus.at('production', () => {     if(cluster.ismaster) { master()  }     if(cluster.isworker) { spawnworker()  } })  function spawnworker() {     const port = app.settings.server.port      app.server = http.createserver(app)     app.server.listen(port, () => {         utils.success(util.format('[+] listening on %d', port))     }) }  function master() {     lodash.foreach(os.cpus(), () => {         cluster.fork()     })      cluster.on('fork', (worker) => {         utils.success('[+] forked worker', worker.id)     })      cluster.on('exit', (worker) => {         utils.success('[-] exited worker', worker.id)     }) }

please note in spawnworker function, app express app created through usual const express = require('express'), app = express()

here questions:

  1. in above code production node.js server, doing inherently flawed?
  2. for express production app ran through pm2, should remove cluster logic above code , use pm2's clustering?

versions

node v5.5.0

nginx v1.4.6

pm2 1.0.0
