Let’s start killing a with single thread Processor //sync processfunction slowSquare(n){var i = 0;while (++i < n * n) {}} slowSquare(100000)slowSquare(100000) $time node app.js **28.04 secs** //async processfunction slowSquareAsync(){setTimeout(function(args) {let i = 0;let n = 100000while (++i < n * n) {}}, 1)} slowSquareAsync()slowSquareAsync() $time node app.js Waiting too long then I aborted (ctrl+c) after wait about 4mins And why my coming hot? :D laptop After read few article I found this Then I tried create very small module, I called Iyem.js , iyem meaning is maid in Bahasa I will try same code but using Iyem.js let iyem = require('iyem') let slowSquareThread = iyem.create(function(){var i = 0;var n = 100000;while (++i < n * n) {}$.finish(i);})slowSquareThread.start()slowSquareThread.onFinish(function(result,err){console.log(result,err)}) function slowSquare(n){var i = 0;while (++i < n * n) {}} slowSquare(100000) $time node app.js **13.2 secs** Wow, cool right? , let’s try more complex multi thread with communication between thread (Pub Sub) let iyem = require('iyem') let importDataReportWorker = iyem.create(function(){const parse = require('parse-csv')const fs = require('fs')const reconcile = require('./Reconcile')parse(fs.readFileSync("./200MB.csv", "utf-8"),function(err,report){$.sub("GET_TRX_SETTELMENT_COLLECTION_DONE",function(dataTrx){var result = reconcile(report,dataTrx)$.finish(result)})})}) let getTrxCollection = iyem.create(function(){const db = require('./db')db.find({transaction_date:"2017-10-10"},function(err,collection){if(err) $.error(err)$.pub("GET_TRX_SETTELMENT_COLLECTION_DONE",collection)$.finish()})}) getTrxCollection.start()importDataReportWorker.start().onFinish(function(err,result){console.log("DONE")console.log(result)}) this is just experimental, Please give me your feedback and dont forget to clap or share _Easy way to manage Multi Thread Js_www.npmjs.com iyem _iyem - Nodejs with Multi Thread_github.com lukluk/iyem If you learned something, click the 💚 to help others find this article.
