Ẹkọ ode oni lori Node.js ni ọdun 2020

Eyin ẹlẹrọ elegbe, agbegbe Metarhia n ṣe afihan si akiyesi rẹ ni igbalode Node.js dajudaju, eyi ti o ni imọran ti o jinlẹ ti gbogbo awọn agbara ati awọn aaye ti Syeed. Itọkasi akọkọ ni bi o ṣe le ṣẹda igbẹkẹle, awọn olupin ohun elo fifuye giga ati awọn API laisi ti so mọ ilana kan pato tabi paapaa ilana, i.e. áljẹbrà owo kannaa sinu lọtọ Layer. Awọn ikowe naa wa pẹlu ọpọlọpọ awọn apẹẹrẹ koodu ti n ṣe afihan apẹrẹ ohun elo to rọ ati awọn imuposi ayaworan, pẹlu ṣiṣẹ pẹlu DBMS nipasẹ ipele iraye si data, ṣiṣẹda awọn ohun elo ibaraenisepo lori awọn oju opo wẹẹbu, aridaju aabo, Tiipa oore-ọfẹ, ibaraẹnisọrọ interprocess, idilọwọ awọn n jo iranti, iwọn ati ikojọpọ ni lilo awọn ilana ati awọn okun. Lọwọlọwọ awọn ikowe 38 wa ninu iṣẹ ikẹkọ (nipa awọn wakati 35 ati ½ ti fidio), Awọn ibi ipamọ 37 pẹlu awọn apẹẹrẹ koodu, 4 PDF pẹlu awọn kikọja. Ṣaaju apakan akọkọ ti iṣẹ Node.js, o gbọdọ kọkọ ṣakoso ni o kere ju apakan asynchronous siseto dajudaju.
