Cov chav kawm niaj hnub ntawm Node.js hauv 2020

Nyob zoo cov phooj ywg engineers, lub zej zog Metarhia nthuav qhia rau koj cov kev xav niaj hnub Node.js chav kawm, uas suav nrog kev txheeb xyuas qhov tob ntawm tag nrho cov peev txheej thiab cov yam ntxwv ntawm lub platform. Lub ntsiab tseem ceeb yog yuav ua li cas los tsim kev txhim khu kev qha, high-load daim ntawv thov servers thiab APIs yam tsis tau khi rau ib lub moj khaum tshwj xeeb los yog txawm raws tu qauv, i.e. abstract business logic rau hauv ib txheej nyias. Cov lus qhuab qhia yog nrog los ntawm ntau tus qauv code qhia txog kev hloov pauv ntawm daim ntawv thov tsim thiab kev tsim vaj tsev, suav nrog kev ua haujlwm nrog DBMS los ntawm cov ntaub ntawv nkag mus rau txheej, tsim kev sib tham sib tham hauv websockets, ua kom muaj kev ruaj ntseg, Kev kaw zoo nkauj, kev sib txuas lus sib txuas, tiv thaiv kev nco qab, scaling thiab clustering ntawm siv cov txheej txheem thiab xov. Tam sim no muaj 38 cov lus qhuab qhia hauv chav kawm (kwv yees li 35 thiab ½ teev video), 37 repositories nrog code piv txwv, 4 PDF nrog slides. Ua ntej qhov tseem ceeb ntawm Node.js chav kawm, koj yuav tsum xub paub yam tsawg kawg ib nrab kawm asynchronous programming.
