Ilmus Node.js 17.0, platvorm, mis v\u00f5imaldab JavaScripti keeles v\u00f5rgu rakenduste t\u00e4itmist. Node.js 17.0 kuulub tavap\u00e4rase toetuse haru alla, mille uuendused viiakse ellu kuni juuni 2022. J\u00e4rgmise n\u00e4dala jooksul l\u00f5petatakse Node.js 16 haru stabiliseerimine, mis saavutab LTS staatuse ja mille toetamine kestab kuni aprilli 2024. Eelmise LTS haru Node.js 14.0 j\u00e4\u00e4b toetuse alla kuni aprilli 2023 ning eelneva LTS haru 12.0 kuni aprilli 2022. <\/p>\n
Peamised t\u00e4iustused: <\/p>\n
Lisaks v\u00f5ib mainida, et Node.js-i uusimates harudes on likvideeritud kaks haavatavust (CVE-2021-22959, CVE-2021-22960), mis v\u00f5imaldavad teostada «HTTP Request Smuggling» (HRS) r\u00fcnnakuid, mis v\u00f5imaldavad saata spetsiaalselt vormindatud kliendip\u00e4ringutega teiste kasutajate p\u00e4ringute sisusse, mida t\u00f6\u00f6deldakse samas jadas, frontendi ja backendi vahel (n\u00e4iteks on v\u00f5imalik sisestada kahjuliku JavaScripti koodi teise kasutaja seanssi). \u00dcksikasjad avalikustatakse hiljem, kuid praegu on teada, et probleemid on tingitud valest t\u00fchikute k\u00e4sitsemisest HTTP-pealkirja nime ja kolonni vahel, samuti erinevast k\u00e4sitsemisest tagasikutsumise ja reavahetuse s\u00fcmbolite osas parameeterplokis, mida kasutatakse p\u00e4ringu keha edastamiseks osade kaupa «chunked» re\u017eiimis. <\/p>\n
Tuletame meelde, et Node.js platvormi saab kasutada veebirakenduste serveri toe pakkumiseks, samuti tavap\u00e4raste klientide ja serveri v\u00f5rguprogrammide loomiseks. Node.js rakenduste funktsionaalsuse laiendamiseks on ette valmistatud suur hulk mooduleid, mis sisaldavad mooduleid rakenduste rakendamiseks. serverid<\/a> HTTP, SMTP, XMPP, DNS, FTP, IMAP, POP3 kliente, mooduleid erinevate veebiraamistike integreerimiseks, WebSocket ja Ajax t\u00f6\u00f6tlejat, andmebaasi \u00fchendusi (MySQL, PostgreSQL, SQLite, MongoDB), malligeneraatorid, CSS-mootorid, kr\u00fcptoalgoritmide rakendused ja autentimiss\u00fcsteemid (OAuth), XML-parsereid. <\/p>\n Suurte paralleelsete p\u00e4ringute t\u00f6\u00f6tlemise tagamiseks kasutab Node.js as\u00fcnkroonset koodik\u00e4ivitamise mudelit, mis p\u00f5hineb mitteblokeerival s\u00fcndmust\u00f6\u00f6tlusel ja tagasiside t\u00f6\u00f6tlejate m\u00e4\u00e4ramisel. \u00dchenduste multiplexerimise meetoditeks on sellised meetodid nagu epoll, kqueue, \/dev\/poll ja select. \u00dchenduste multiplexerimiseks kasutatakse libuv teeki, mis on libevi peal Unix-s\u00fcsteemides ja IOCP peal Windowsis. T\u00f6\u00f6de v\u00f5rgu loomise jaoks kasutatakse libeio teeki, niisuguste mitteblokeerivate DNS-p\u00e4ringute t\u00f6\u00f6tlemiseks on integreeritud c-ares. K\u00f5ik s\u00fcsteemikutsed, mis p\u00f5hjustavad blokeerimist, toimuvad teede grupis ja edastavad seej\u00e4rel oma t\u00f6\u00f6 tulemuse tagasi anon\u00fc\u00fcmse kanali kaudu (pipe). JavaScripti koodi t\u00e4itmine toimub Google'i v\u00e4lja t\u00f6\u00f6tatud V8 mootori kaudu (Microsoft arendab lisaks versiooni Node.js Chakra-Core mootori kasutades). <\/p>\n Node.js on oma olemuselt sarnane Perl AnyEvent, Ruby Event Machine, Python Twisted ja Tcl'i s\u00fcndmuste rakendustega, kuid Node.js s\u00fcndmust\u00f6\u00f6tlus ts\u00fckkel on arendajalt varjatud ja meenutab s\u00fcndmuste t\u00f6\u00f6tlemist veebirakenduses, mis t\u00f6\u00f6tab brauseris. Node.js rakenduste kirjutamisel tuleb arvestada s\u00fcndmep\u00f5hise programmeerimise erip\u00e4ra; n\u00e4iteks, selle asemel et k\u00e4ivitada 'var result = db.query('select..');' oodates selle l\u00f5petamist ja seej\u00e4rel tulemuste t\u00f6\u00f6tlemist, kasutatakse Node.js-is as\u00fcnkroonse t\u00e4itmise p\u00f5him\u00f5tet, st koodi muudetakse kujule 'db.query('select..', function (result) {tulemuse t\u00f6\u00f6tlemine});', mille k\u00e4igus kaob juhtimine koheselt edasisele koodile ning p\u00e4ringu tulemus t\u00f6\u00f6deldakse andmete saabumise ajal. \u0421\u043e\u0441\u0442\u043e\u044f\u043b\u0441\u044f \u0440\u0435\u043b\u0438\u0437 Node.js 17.0, \u043f\u043b\u0430\u0442\u0444\u043e\u0440\u043c\u044b \u0434\u043b\u044f \u0432\u044b\u043f\u043e\u043b\u043d\u0435\u043d\u0438\u044f \u0441\u0435\u0442\u0435\u0432\u044b\u0445 \u043f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u0439 \u043d\u0430 \u044f\u0437\u044b\u043a\u0435 JavaScript.
